How to Add icons adjacent to titles for Android Navigation Drawer

Question

I am currently working on an android app for 4.2.2 that uses the new NavigationDrawer. It works like a charm except for adding icons.

I found some sample code in which the List view becomes a Relative layout in which 2 parallel arrays are nested and rendered by an Array Adapter based on a menu model a way that they are synchronized, I think.

Here is the MainActivity:

package com.sorin.medisynced.main;

import android.app.Activity;
import android.app.SearchManager;
import android.content.Intent;
import android.content.res.Configuration;
import android.os.Bundle;
import android.support.v4.app.ActionBarDrawerToggle;
import android.support.v4.view.GravityCompat;
import android.support.v4.widget.DrawerLayout;
import android.view.Menu;
import android.view.MenuInflater;
import android.view.MenuItem;
import android.view.View;
import android.widget.AdapterView;
import android.widget.ArrayAdapter;
import android.widget.ListView;
import android.widget.Toast;

import com.sorin.medisynced.R;
import com.sorin.medisynced.filepickerio.FilepickerSaver;
import com.sorin.medisynced.filepickerio.FilepickerViewer;

    private String[] menuItemsEmergency;
    private CharSequence mDrawerTitle;
    private CharSequence mTitle;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main_drawer);
        mTitle = mDrawerTitle = getTitle();
        // set click listener for list drawer
        // mDrawerList.setOnItemClickListener(new DrawerItemClickListener());
        // enable ActionBar app icon to behave as action to toggle nav drawer
        getActionBar().setDisplayHomeAsUpEnabled(true);
        getActionBar().setHomeButtonEnabled(true);

        mDrawerLayout = (DrawerLayout) findViewById(R.id.drawer_layout);
        mDrawerList = (ListView) findViewById(R.id.drawer);

        // set a custom shadow that overlays the main content when the drawer
        // opens
        mDrawerLayout.setDrawerShadow(R.drawable.drawer_shadow,
                GravityCompat.START);

Here is the menu model:

package com.sorin.medisynced.main;


public class NsMenuItemModel {

    public int title;
    public int iconRes;
    public boolean isHeader;

    public NsMenuItemModel(int title, int iconRes,boolean header) {
        this.title = title;
        this.iconRes = iconRes;
        this.isHeader=header;
    }

    public NsMenuItemModel(int title, int iconRes) {
        this(title,iconRes,false);
    }

}

Here ist the ArrayAdapter implementation:

package com.sorin.medisynced.main;


import android.content.Context;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.ArrayAdapter;
import android.widget.ImageView;

import com.sorin.medisynced.R;

public class NsMenuAdapter extends ArrayAdapter<NsMenuItemModel> {

    /*
     * public NsMenuAdapter(Context context, int resource, int
     * textViewResourceId, String[] objects) { super(context,
     * R.layout.ns_menu_row, textViewResourceId, objects); }
     */

    public NsMenuAdapter(Context context) {
        super(context, 0);
    }

    public void addHeader(int title) {
        add(new NsMenuItemModel(title, -1, true));
    }

    public void addItem(int title, int icon) {
        add(new NsMenuItemModel(title, icon, false));
    }

    public void addItem(NsMenuItemModel itemModel) {
        add(itemModel);
    }

    @Override
    public int getViewTypeCount() {
        return 2;
    }

    @Override
    public int getItemViewType(int position) {
        return getItem(position).isHeader ? 0 : 1;
    }

    @Override
    public boolean isEnabled(int position) {
        return !getItem(position).isHeader;
    }

    public static class ViewHolder {
        public final TextView textHolder;
        public final ImageView imageHolder;

        public ViewHolder(TextView text1, ImageView image1) {
            this.textHolder = text1;
            this.imageHolder = image1;
        }
    }

    public View getView(int position, View convertView, ViewGroup parent) {

        NsMenuItemModel item = getItem(position);
        ViewHolder holder = null;
        View view = convertView;

        if (view == null) {
            int layout = R.layout.ns_menu_row;
            if (item.isHeader)
                layout = R.layout.ns_menu_row_header;

            view = LayoutInflater.from(getContext()).inflate(layout, null);

            TextView text1 = (TextView) view.findViewById(R.id.menurow_title);
            ImageView image1 = (ImageView) view.findViewById(R.id.menurow_icon);
            view.setTag(new ViewHolder(text1, image1));
        }

        if (holder == null && view != null) {
            Object tag = view.getTag();
            if (tag instanceof ViewHolder) {
                holder = (ViewHolder) tag;
            }
        }


        if(item != null && holder != null)
        {
            if (holder.textHolder != null)
                holder.textHolder.setText(item.title);

            if (holder.imageHolder != null) {
                if (item.iconRes > 0) {
                    holder.imageHolder.setVisibility(View.VISIBLE);
                    holder.imageHolder.setImageResource(item.iconRes);
                } else {
                    holder.imageHolder.setVisibility(View.GONE);
                }
            }
        }

        return view;        
    }

}

and the main layout:

<!-- The main content view -->

<RelativeLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:id="@+id/content_frame"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:paddingBottom="@dimen/activity_vertical_margin"
    android:paddingLeft="@dimen/activity_horizontal_margin"
    android:paddingRight="@dimen/activity_horizontal_margin"
    android:paddingTop="@dimen/activity_vertical_margin"
    tools:context=".MediSyncedMainActivity" >

    <TextView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="@string/drawer_text" />
</RelativeLayout>

<!-- The navigation drawer -->

<ListView
    android:id="@+id/drawer"
    android:layout_width="240dp"
    android:layout_height="match_parent"
    android:layout_gravity="start"
    android:background="#DADADC"
    android:choiceMode="singleChoice"
    android:divider="@android:color/darker_gray"
    android:dividerHeight="1dp"
    android:showDividers="middle" />

How can I simplify the approach. Is there a way to use one array instead of such a complicated structure.

B.t.w. you can find my project on github under: https://github.com/greenspand/MediSynced

It is a medical app, hence the name. Thx y'all.

What is the problem? Is the layout behaving as it's supposed to be and you're just looking for simpler solution, or does it do something else? What should the result look like? – Possessive

Exactly, I am looking for a simpler solution. Instead of using an Array adapter and implement several string arrays. – Mokpo

Answer 1

here's my layout:

<LinearLayout  xmlns:android="http://schemas.android.com/apk/res/android"
  android:layout_width="fill_parent"
  android:layout_height="wrap_content" >

  <ImageView
    android:id="@+id/drawer_item_icon"
    android:layout_width="wrap_content"
    android:layout_height="match_parent"
    android:layout_marginLeft="10sp"
    android:layout_marginRight="10sp"
    android:src="@drawable/ic_launcher" />

  <TextView
    android:id="@+id/drawer_item_text"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content" 
    android:textSize="25sp"
    android:paddingTop="8sp"
    android:paddingBottom="8sp"
    android:paddingLeft="15sp" />

</LinearLayout>

You should really only use sps for text sizes. For everything else, use dp. See the documentation – Picker

Answer 2

You can use a custom list view along with the list adapter to display the counter besides the list item in the drawer. And then add whatever code you want to your counter method. Here's the code I implemented in my navigation drawer supported android app :

getter/setter methods class for the drawer :

package info.aea.drawer;

public class NavDrawerItem {

    private String title;
    private String tag;
    private int icon;
    private String count = "0";
    // boolean to set visibility of the counter
    private boolean isCounterVisible = false;

    public NavDrawerItem(){}

    public NavDrawerItem(String title, String tag, int icon){
        this.title = title;
        this.tag = tag;
        this.icon = icon;
    }

    public NavDrawerItem(String title, String tag, int icon, boolean isCounterVisible, String count){
        this.title = title;
        this.tag = tag;
        this.icon = icon;
        this.isCounterVisible = isCounterVisible;
        this.count = count;
    }

    public String getTitle(){
        return this.title;
    }

    public String getTag(){
        return this.tag;
    }

    public int getIcon(){
        return this.icon;
    }

    public String getCount(){
        return this.count;
    }

    public boolean getCounterVisibility(){
        return this.isCounterVisible;
    }

    public void setTitle(String title){
        this.title = title;
    }

    public void setTag(String tag){
        this.tag = tag;
    }

    public void setIcon(int icon){
        this.icon = icon;
    }

    public void setCount(String count){
        this.count = count;

    public void setCounterVisibility(boolean isCounterVisible){
        this.isCounterVisible = isCounterVisible;
    }
}

This is the list adapter I used to display the list. check the display count method in the end :

import android.widget.TextView;

public class NavDrawerListAdapter extends BaseAdapter {

    private Context context;
    private ArrayList<NavDrawerItem> navDrawerItems;

    public NavDrawerListAdapter(Context context, ArrayList<NavDrawerItem> navDrawerItems){
        this.context = context;
        this.navDrawerItems = navDrawerItems;
    }

    @Override
    public int getCount() {
        return navDrawerItems.size();
    }

    @Override
    public Object getItem(int position) {       
        return navDrawerItems.get(position);
    }

    @Override
    public long getItemId(int position) {
        return position;
    }

    @Override
    public View getView(int position, View convertView, ViewGroup parent) {
        if (convertView == null) {
            LayoutInflater mInflater = (LayoutInflater)
                    context.getSystemService(Activity.LAYOUT_INFLATER_SERVICE);
            convertView = mInflater.inflate(R.layout.drawer_list_item, null);
        }

        ImageView imgIcon = (ImageView) convertView.findViewById(R.id.icon);
        TextView txtTitle = (TextView) convertView.findViewById(R.id.title);
        TextView txtTag = (TextView) convertView.findViewById(R.id.tag);
        TextView txtCount = (TextView) convertView.findViewById(R.id.counter);

        imgIcon.setImageResource(navDrawerItems.get(position).getIcon());        
        txtTitle.setText(navDrawerItems.get(position).getTitle());
        txtTag.setText(navDrawerItems.get(position).getTag());

        // displaying count
        // check whether it set visible or not
        if(navDrawerItems.get(position).getCounterVisibility()){
            txtCount.setText(navDrawerItems.get(position).getCount());
        }else{
            // hide the counter view
            txtCount.setVisibility(View.GONE);
        }

        return convertView;
    }

}

Answer 3

Simplest way I did it is this way:

1. Make this as your drawer xml

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tashan="http://schemas.android.com/apk/res-auto"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:minHeight="?android:attr/listPreferredItemHeightSmall"
android:orientation="horizontal"
android:padding="@dimen/spacing_small" >

<ImageView
    android:id="@+id/drawer_item_icons"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_gravity="center_vertical"
    android:layout_marginLeft="@dimen/spacing_small"
    android:layout_marginStart="@dimen/spacing_small"
    android:contentDescription="@string/test_string"/>

<TextView
    android:id="@+id/drawer_item_labels"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:layout_gravity="center_vertical"
    android:layout_marginLeft="@dimen/spacing_normal"
    android:layout_marginStart="@dimen/spacing_small"
    android:paddingLeft="@dimen/spacing_small"
    android:paddingRight="@dimen/spacing_small"
    android:textAppearance="?android:attr/textAppearanceSmall"
    android:textColor="#58585b" />

</LinearLayout>

2. Add these values to your 'dimens.xml'. Never hardcode values!

    <dimen name="spacing_normal">16dp</dimen>
    <dimen name="spacing_small">8dp</dimen>

3. For Icons array add this String Array to 'strings.xml

<string-array name="array_main_menu">
    <item>@drawable/1</item>
    <item>@drawable/2</item>
    <item>@drawable/3</item>
    <item>@drawable/4</item>
    <item>@drawable/5</item>
</string-array>

4. In your Adapter access this array by using a Typed Array instance.

    TypedArray typedArray=getResources().obtainTypedArray(R.array.array_main_menu);

5. Inside the getView of your adapter, set image to Imageview like this.

 mIcon.setImageResource(typedArray.getResourceId(position, -1));

here mIcon is your ImageView.

Answer 4

With recent versions of Support Library, the easiest way is to use a NavigationView. Here is a nice tutorial, and here is the official documentation.

A NavigationView is included as second view in the DrawerLayout (instead of ListView from OP code), for example:

     <android.support.design.widget.NavigationView
     android:id="@+id/navigation"
     android:layout_width="wrap_content"
     android:layout_height="match_parent"
     android:layout_gravity="start"
     app:menu="@menu/left_menu" />

Then, the menu should be populated with titles and icons, like (left_menu.xml):

<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:android="http://schemas.android.com/apk/res/android">
<group
    android:id="@+id/leftMenuId"
    android:checkableBehavior="single">
    <item
        android:id="@+id/item1"
        android:icon="@drawable/ic_zzblack_24dp"
        android:title="Title1" />
    <item
        android:id="@+id/settings"
        android:icon="@drawable/ic_settings_black_24dp"
        android:title="Settings" />
</group>
</menu>

For more details, please refer to the first link.
