How to set custom typeface to items in NavigationView?

Question

With the new NavigationView, we are able to set a drawer's items through a menu resource in XML.

With that, we can set each item with something like

<item
  android:id="@+id/drawer_my_account"
  android:icon="@drawable/ic_my_account"
  android:title="@string/drawer_my_account" />

But now, I want to set a custom typeface to each of those items in my drawer, and I could not find a way to do that, either by XML or by Java code. Is there a way to do it?

Answer 1

just add following class file to your project.

import android.graphics.Paint;
import android.graphics.Typeface;
import android.text.TextPaint;
import android.text.style.TypefaceSpan;

public class CustomTypefaceSpan extends TypefaceSpan {

    private final Typeface newType;

    public CustomTypefaceSpan(String family, Typeface type) {
        super(family);
        newType = type;
    }

    @Override
    public void updateDrawState(TextPaint ds) {
        applyCustomTypeFace(ds, newType);
    }

    @Override
    public void updateMeasureState(TextPaint paint) {
        applyCustomTypeFace(paint, newType);
    }

    private static void applyCustomTypeFace(Paint paint, Typeface tf) {
        int oldStyle;
        Typeface old = paint.getTypeface();
        if (old == null) {
            oldStyle = 0;
        } else {
            oldStyle = old.getStyle();
        }

        int fake = oldStyle & ~tf.getStyle();
        if ((fake & Typeface.BOLD) != 0) {
            paint.setFakeBoldText(true);
        }

        if ((fake & Typeface.ITALIC) != 0) {
            paint.setTextSkewX(-0.25f);
        }

        paint.setTypeface(tf);
    }
}

then create following method to your activity

private void applyFontToMenuItem(MenuItem mi) {
        Typeface font = Typeface.createFromAsset(getAssets(), "ds_digi_b.TTF");
        SpannableString mNewTitle = new SpannableString(mi.getTitle());
        mNewTitle.setSpan(new CustomTypefaceSpan("" , font), 0 , mNewTitle.length(),  Spannable.SPAN_INCLUSIVE_INCLUSIVE);
        mi.setTitle(mNewTitle);
}

and call it from activity.

navView = (NavigationView) findViewById(R.id.navView);
        Menu m = navView.getMenu();
        for (int i=0;i<m.size();i++) {
            MenuItem mi = m.getItem(i);

            //for aapplying a font to subMenu ...
            SubMenu subMenu = mi.getSubMenu();
            if (subMenu!=null && subMenu.size() >0 ) {
                for (int j=0; j <subMenu.size();j++) {
                    MenuItem subMenuItem = subMenu.getItem(j);
                    applyFontToMenuItem(subMenuItem);
                }
            }

            //the method we have create in activity
            applyFontToMenuItem(mi);
        }

and here is my output

In my answer there is no onGobalLayout ..Bcause i have use custom type face span .. because SpannableString allow formatting ..but don't allow to change the font for that i have use custom type face span class .. – Forsook

Another alternative is this guy. It solves the problem of custom fonts and adds font caching--a very important thing to have if you're inflating fonts a ton of times. – Doelling

Where is the method getAssets() defined? It looks like that is missing from the code above. – Designed

People who downvote. Please try to give the reason so that i can understand my mistake. And not only on my answer, On any answer if you donwvote give the reason. – Forsook

Got this error This class implements Parcelable but does not provide a CREATOR field – Twodimensional

What ?? This class is not parcelable .. plz check your code properly – Forsook

TypefaceSpan implements ParcelableSpan. here's a generic creator field, but you'll need to add another constructor that takes the parcel "in" and calls super(in): public static final Creator CREATOR = new Creator() { public HopstaTypeFace createFromParcel(Parcel in) { return new HopstaTypeFace(in); } public HopstaTypeFace[] newArray(int size) { return new HopstaTypeFace[size]; } }; – Dwanadwane

@AdeelTurk Yes it gave me that error but I just removed that inspection. Code works like a charm +1ed. – Pasquale

I git This class implements Parcelable but does not provide a CREATOR field error. i'm not able to overcome – Berne

I use this approach for menu item in toolbar. All fine on android 5 but on 7 version it isn't work. Do you have any ideas? – Mezzotint

@Moinkhan: What, if I need to change font size as well? – Teryn

font size is very small as normal ? why – Supergalaxy

Answer 3

Use the app:itemTextAppearance property and give it a custom style that you create in the styles.xml file of your app.

 <com.google.android.material.navigation.NavigationView
        android:id="@+id/nav_view"
        android:layout_width="wrap_content"
        android:layout_height="match_parent"
        android:layout_gravity="start"
        android:fitsSystemWindows="true"
        app:headerLayout="@layout/nav_header_main"
        android:background="@drawable/nav_bg_gradient"
        android:theme="@style/NavigationView"
        app:itemIconTint="@color/colorWhite"
        app:itemTextColor="@color/colorWhite"
        app:itemTextAppearance="@style/NavigationViewItemText"
        app:menu="@menu/main_drawer">

In styles.xml create this custom style overriding the TextAppearance.Material3.LabelLarge, as the Material documentation suggests.

<style name="NavigationViewItemText" parent="TextAppearance.Material3.LabelLarge">
        <item name="android:textColor">@color/colorWhite</item>
        <item name="android:textSize">12sp</item>
        <item name="android:fontFamily">sans-serif-thin</item>
    </style>

Meill

@chris838 , Its work if you follow this for adding your custom font : developer.android.com/guide/topics/ui/look-and-feel/… – Avestan

This should be accepted as it is the most up-to-date solution! – Retread

Perfect solution. However if you are using custom fonts then use <item name="android:fontFamily">@font/custom-font</item> – Teen

That's the way to do it. Override the TextAppearance.Material3.LabelLarge style instead of the TextAppearance.Medium, that's the right one, as per the documentation. – Zoogeography

Answer 4

Is there a way to do it?

Yes. The NavigationView doesn't provide a direct way of handling this, but it can easily be achieved using View.findViewsWithText.

There are two things that will help us handle this.

1. Each MenuItem view is a TextView. So, that makes applying your Typeface that much easier. For more information on the TextView actually used by NavigationView, see NavigationMenuItemView.
2. NavigationView provides a callback when a MenuItem is selected. We're going to have to supply each MenuItem with a unique id and this callback will help generify those ids as much as possible, which means a little less code later on. Although, this is more related to whether or not you have a SubMenu.

Implementation

Notice each MenuItem id is simply menuItem+Position. This will come in handy later when we're finding the View for each MenuItem.

<group android:checkableBehavior="single">
    <item
        android:id="@+id/menuItem1"
        android:icon="@drawable/ic_dashboard"
        android:title="MenuItem 1" />
    <item
        android:id="@+id/menuItem2"
        android:icon="@drawable/ic_event"
        android:title="MenuItem 2" />
    <item
        android:id="@+id/menuItem3"
        android:icon="@drawable/ic_headset"
        android:title="MenuItem 3" />
    <item
        android:id="@+id/menuItem4"
        android:icon="@drawable/ic_forum"
        android:title="MenuItem 4" />
</group>

<item android:title="Sub items" >
    <menu>
        <item
            android:id="@+id/menuItem5"
            android:icon="@drawable/ic_dashboard"
            android:title="Sub item 5" />
        <item
            android:id="@+id/menuItem6"
            android:icon="@drawable/ic_forum"
            android:title="Sub item 6" />
    </menu>
</item>

---

/** The total number of menu items in the {@link NavigationView} */
private static final int MENU_ITEMS = 6;
/** Contains the {@link MenuItem} views in the {@link NavigationView} */
private final ArrayList<View> mMenuItems = new ArrayList<>(MENU_ITEMS);

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    ...
    final NavigationView navView = ...
    // Grab the NavigationView Menu
    final Menu navMenu = navView.getMenu();
    // Install an OnGlobalLayoutListener and wait for the NavigationMenu to fully initialize
    navView.getViewTreeObserver().addOnGlobalLayoutListener(new ViewTreeObserver.OnGlobalLayoutListener() {
        @Override
        public void onGlobalLayout() {
            // Remember to remove the installed OnGlobalLayoutListener
            navView.getViewTreeObserver().removeOnGlobalLayoutListener(this);
            // Loop through and find each MenuItem View
            for (int i = 0, length = MENU_ITEMS; i < length; i++) {
                final String id = "menuItem" + (i + 1);
                final MenuItem item = navMenu.findItem(getResources().getIdentifier(id, "id", getPackageName()));
                navView.findViewsWithText(mMenuItems, item.getTitle(), View.FIND_VIEWS_WITH_TEXT);
            }
            // Loop through each MenuItem View and apply your custom Typeface
            for (final View menuItem : mMenuItems) {
                ((TextView) menuItem).setTypeface(yourTypeface, Typeface.BOLD);
            }
        }
    });
}

You can see how using a generic MenuItem id allows you to utilize Resources.getIdentifier and save a few lines of code.

SubMenu caveat

Something to keep in mind. You need to explicitly loop over your N menu items rather than using Menu.size. Otherwise, your SubMenu items won't be recognized. In other words, if you don't have a SubMenu, another way of doing this would be:

for (int i = 0, length = navMenu.size(); i < length; i++) {
    final MenuItem item = navMenu.getItem(i);
    navigationView.findViewsWithText(mMenuItems, item.getTitle(), View.FIND_VIEWS_WITH_TEXT);
}

And you don't have to worry about applying a unique id to each MenuItem.

First of all, thank you for the answer. - - - I see that your code works to set the custom typeface, but I don't feel comfortable with using OnGlobalLayoutListener and traversing the ViewTree that way, specially by using getResources().getIdentifier(...): that is exactly why I asked for an easy way. Also, this looks like you're relying on the items title to get the reference to them - this will make me a prisoner of my titles, right? I'd love to see a less coupled option. – Corvus

You aren't going to get one. NavigationView simply doesn't provide an "easy" way to handle this. I wouldn't be worried about using the OnGlobalLayoutListener or using Resources.getIdentifier though. These things are safe to use and also used internally by the Android framework too. You would be a prisoner to your titles, yes. I'd love to see a less coupled option too. I like to imagine the design library will be a little more customizable in this aspect later on. – Alanaalanah

findViewsWithText fails to find views which are outside the screen bounds. Is it expected behavior? – Imprecision

As @Imprecision says, if your menu happens to go off the screen this technique will fail to style those menu items. My workaround was to wait until all the items were found with if(mMenuItems.size() != menu.size()) { return; } before removing the listener and styling them. This could be a performance concern but was fine in my particular case (only one extra call to onGlobalLayout() was needed). – Sabadilla

When I try casting my MenuItem to a Textview it becomes null. Any idea why this is? I can change the text of it without problem before trying to typecast it. – Gametangium

Answer 5

I have used app:theme

<android.support.design.widget.NavigationView
    android:id="@+id/nav_view"
    android:layout_width="wrap_content"
    android:layout_height="match_parent"
    android:layout_gravity="start"
    android:background="@color/colorMenuBackground"
    android:fitsSystemWindows="true"
    app:headerLayout="@layout/nav_header_main"
    app:menu="@menu/activity_main_drawer"
    app:theme="@style/NavigationViewTextAppearance"
   />

styles.xml :

<style name="NavigationViewTextAppearance">
    <item name="android:ellipsize">end</item>
    <item name="android:fontFamily">@font/badscript_regular</item>
</style>

Answer 6

A different way to set your custom font:

1. You can add your fonts in a "font" folder, and then you can use them in any TextView (or wherever you needed)

An example of font.xml:

<?xml version="1.0" encoding="utf-8"?>
<font-family xmlns:android="http://schemas.android.com/apk/res/android">
    <font
        android:font="@font/nunito_bold"
        android:fontStyle="normal"
        android:fontWeight="400" />
</font-family>

2. In your styles.xml file, you can customize your item text style with that font, and color, wherever you need (from @Moonis Abidi answer)

 <style name="NavigationText" parent="@android:style/TextAppearance.Medium">
        <item name="android:textColor">@android:color/white</item>
        <item name="android:textSize">12sp</item>
        <item name="android:fontFamily">@font/nunito_semibold</item>
    </style>

3. Now, you only have to specify this in your navigation view with app:itemTextAppearance:

<android.support.design.widget.NavigationView
        android:id="@+id/nav_view"
        android:layout_width="wrap_content"
        android:layout_height="match_parent"
        android:layout_gravity="start"
        android:fitsSystemWindows="true"
        app:headerLayout="@layout/nav_header"
        app:menu="@menu/main_menu"
        app:itemTextAppearance="@style/NavigationText"/>

// ------------- Also, if you need to use this font from others TextViews, you can use it like

 <TextView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:fontFamily="@font/nunito_bold"/>

Answer 7

Not a custom typeface, but another way to change the navigation items' font. Create a layout named design_navigation_item.xml.

<android.support.design.internal.NavigationMenuItemView
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="?attr/listPreferredItemHeightSmall"
    android:paddingLeft="?attr/listPreferredItemPaddingLeft"
    android:paddingRight="?attr/listPreferredItemPaddingRight"
    android:drawablePadding="@dimen/navigation_icon_padding"
    android:gravity="center_vertical|start"
    android:maxLines="1"
    android:fontFamily="sans-serif-thin"
    android:textSize="22sp"
    android:textAppearance="?attr/textAppearanceListItem" />

Then change the fontFamily to the desired font.

And where to use this layout ? – Avestan

Answer 8

It's a bit late to answer but I found a cleaner way to do it, so I would like to share.

• Make a custom view NavFontTextView.java:

  import android.content.Context;
  import android.support.design.internal.NavigationMenuItemView;
  import android.util.AttributeSet;
  
  import utils.CustomFontHelper;
  
  public class NavFontTextView extends NavigationMenuItemView {
  Context mContext;
  
  public NavFontTextView(Context context) {
      super(context);
      mContext = context;
      setDefaultFont();
  }
  
  public NavFontTextView(Context context, AttributeSet attrs) {
      super(context, attrs);
      mContext = context;
      setDefaultFont();
      CustomFontHelper.setCustomFont(this, context, attrs);
  }
  
  public NavFontTextView(Context context, AttributeSet attrs, int defStyleAttr) {
      super(context, attrs, defStyleAttr);
      mContext = context;
      setDefaultFont();
      CustomFontHelper.setCustomFont(this, context, attrs);
  }
  
  public void setDefaultFont() {
      CustomFontHelper.setCustomFont(this, "fonts/SourceSansPro-Regular.ttf", mContext);
  }
  }
  

• Make a file called CustomFontHelper.java:

  import android.content.Context;
  import android.content.res.TypedArray;
  import android.graphics.Typeface;
  import android.util.AttributeSet;
  import android.widget.TextView;
  
  /**
   * Taken from: https://mcmap.net/q/56155/-how-to-set-a-particular-font-for-a-button-text-in-android
   */
  public class CustomFontHelper {
  /**
   * Sets a font on a textview based on the custom com.my.package:font attribute
   * If the custom font attribute isn't found in the attributes nothing happens
   * @param textview
   * @param context
   * @param attrs
   */
  public static void setCustomFont(TextView textview, Context context, AttributeSet attrs) {
      TypedArray a = context.obtainStyledAttributes(attrs, R.styleable.CustomFont);
      String font = a.getString(R.styleable.CustomFont_font);
      setCustomFont(textview, font, context);
      a.recycle();
  }
  
  /**
   * Sets a font on a textview
   * @param textview
   * @param font
   * @param context
   */
  public static void setCustomFont(TextView textview, String font, Context context) {
      if(font == null) {
          return;
      }
      Typeface tf = FontCache.get(font, context);
      if(tf != null) {
          textview.setTypeface(tf);
      }
  }
  }
  

• Make a layout layout/design_navigation_item.xml (the name must be exactly the same):

  <?xml version="1.0" encoding="utf-8"?>
  <custom_view.NavFontTextView xmlns:android="http://schemas.android.com/apk/res/android"
  xmlns:app="http://schemas.android.com/apk/res-auto"
  android:layout_width="match_parent"
  android:layout_height="?attr/listPreferredItemHeightSmall"
  android:drawablePadding="10dp"
  android:gravity="center_vertical|start"
  android:maxLines="1"
  android:paddingLeft="?attr/listPreferredItemPaddingLeft"
  android:paddingRight="?attr/listPreferredItemPaddingRight"
  app:font="fonts/SourceSansPro-Bold.ttf" />
  

• Place your font file SourceSansPro-Bold.ttf in this path: app/src/main/assets/fonts/SourceSansPro-Bold.ttf

You're good to go! This way, you can keep your main activity cleaner.

I really like this approach but it doesn't seem to work, because NavigationMenuItemView doesn't inherit from TextView. Is there a missing step? – Calibre

Answer 9

I've refactored @adneal's answer to this. It loops over the menu items(without going into sub items, only top level items) according to the index instead of the id and sets the Typeface.

Replace rightNavigationView with your NavigationView and {TYPEFACE} with your desired TypeFace

final Menu navMenu = rightNavigationView.getMenu();
        rightNavigationView.getViewTreeObserver().addOnGlobalLayoutListener(new ViewTreeObserver.OnGlobalLayoutListener() {
            @Override
            public void onGlobalLayout() {
                ArrayList<View> menuItems = new ArrayList<>(); // save Views in this array
                rightNavigationView.getViewTreeObserver().removeOnGlobalLayoutListener(this); // remove the global layout listener
                for (int i = 0; i < navMenu.size(); i++) {// loops over menu items  to get the text view from each menu item
                    final MenuItem item = navMenu.getItem(i);
                    rightNavigationView.findViewsWithText(menuItems, item.getTitle(), View.FIND_VIEWS_WITH_TEXT);
                }
                for (final View menuItem : menuItems) {// loops over the saved views and sets the font
                    ((TextView) menuItem).setTypeface({TYPE}, Typeface.BOLD);
                }
            }
        });

Answer 10

for those who use @Moinkhan answer, for applying font to every part of your menus use that solution and for every header section use id. your menu like this..

<item android:title="@string/others" android:id="@+id/nav_others">
    <menu>
        <item
            android:id="@+id/contact"
            android:title="@string/contact"/>
    </menu>
</item>

and solution like this..

navMenu = navView.getMenu();
    MenuItem item= navView.getMenu().findItem(R.id.nav_others);
    applyFontToMenuItem(item);

maybe it helps someone.

Answer 11

I really loved the solution of "Dragon who spits fire"'s but I didn't get the textview. This could be done by doing the following:

TextView textView = (CheckedTextView) findViewById(android.support.design.R.id.design_menu_item_text);

public class StyledMenuItem extends NavigationMenuItemView {
public StyledMenuItem(Context context) {
    super(context);
}

public StyledMenuItem(Context context, AttributeSet attrs) {
    super(context, attrs);
    if (!isInEditMode()) {
        setCustomFont(context, attrs);
        setFilterTouchesWhenObscured(true);

Add the font file in the res/font/ folder to bundle fonts as resources, then You can change it using style resources. In your styles.xml :

<style name="Widget.BottomNavigationView" 
   parent="Widget.Design.BottomNavigationView">
   <item name="fontFamily">@font/your_font</item>
</style>

Then apply it as a theme in your view:

<android.support.design.widget.BottomNavigationView
   ...
   android:theme="@style/Widget.BottomNavigationView"
/>

This is another approach:

A NavigationView has children called NavigationMenuItemView. A NavigationMenuItemView has two children. One is AppCompatCheckedTextView.

Override onLayout method of the NavigationView like bellow and change Typefase of the AppCompatCheckedTextView:

public final class NavigationViewWithCustomFont extends NavigationView{
    private final Context context;
    private Typeface fontFace;

    public NavigationViewWithCustomFont(Context context, AttributeSet attrs){
        super(context, attrs);
        this.context = context;
        this.fontFace = null;
    }

    @Override
    protected void onLayout(boolean changed, int left, int top, int right, int bottom){
        super.onLayout(changed, left, top, right, bottom);
        final ViewGroup navMenuView = (ViewGroup)getChildAt(0);
        final int navMenuItemsCount = navMenuView.getChildCount();
        ViewGroup itemView;

        if(fontFace == null){
            fontFace = Typeface.createFromAsset(context.getAssets(), context.getString(R.string.BTrafficBold));
        }
        for(int i=0; i<navMenuItemsCount; i++){
            itemView = (ViewGroup)navMenuView.getChildAt(i);

            if(itemView instanceof NavigationMenuItemView ){
                CheckedTextView checkedTextView = (CheckedTextView)itemView.getChildAt(0);
                checkedTextView.setTypeface(fontFace, Typeface.BOLD);
            }
        }
    }
}

BottomNavigationView bottom_nav = findViewById(R.id.bottom_nav);
Typeface font = Typeface.createFromAsset(getAssets(), "--your customized font file--");
for (int i = 0; i <bottom_nav.getMenu().size(); i++) {
        MenuItem menuItem = bottom_nav.getMenu().getItem(i);
        SpannableStringBuilder spannableTitle = new SpannableStringBuilder(menuItem.getTitle());
        spannableTitle.setSpan(font.getStyle(), 0, spannableTitle.length(), Spannable.SPAN_INCLUSIVE_INCLUSIVE);
        menuItem.setTitle(spannableTitle);
    }

Answer 15

applyFontToMenuItem(popup.getMenu().getItem(0));
private void applyFontToMenuItem(MenuItem mi) {
    Typeface font = Typeface.createFromAsset(getAssets(), "fonts/Redressed.ttf");       
    SpannableString mNewTitle = new SpannableString(mi.getTitle());
    mNewTitle.setSpan(new CustomTypefaceSpan("", font), 0, mNewTitle.length(),pannable.SPAN_INCLUSIVE_INCLUSIVE);
    mi.setTitle(mNewTitle);
}
