In my research, there is no way to add external font to the xml file. Only the 3 default font is available in xml
But you can use in java using this code.
Typeface tf = Typeface.createFromAsset(getAssets(),"fonts/verdana.ttf");
textfield.setTypeface(tf,Typeface.BOLD);
Update:
Now I find a way to do this by creating a custom class extending the TextView and use that in the xml file.
public class TextViewWithFont extends TextView {
private int defaultDimension = 0;
private int TYPE_BOLD = 1;
private int TYPE_ITALIC = 2;
private int FONT_ARIAL = 1;
private int FONT_OPEN_SANS = 2;
private int fontType;
private int fontName;
public TextViewWithFont(Context context) {
super(context);
init(null, 0);
}
public TextViewWithFont(Context context, AttributeSet attrs) {
super(context, attrs);
init(attrs, 0);
}
public TextViewWithFont(Context context, AttributeSet attrs, int defStyle) {
super(context, attrs, defStyle);
init(attrs, defStyle);
}
private void init(AttributeSet attrs, int defStyle) {
// Load attributes
final TypedArray a = getContext().obtainStyledAttributes(
attrs, R.styleable.font, defStyle, 0);
fontName = a.getInt(R.styleable.font_name, defaultDimension);
fontType = a.getInt(R.styleable.font_type, defaultDimension);
a.recycle();
MyApplication application = (MyApplication ) getContext().getApplicationContext();
if (fontName == FONT_ARIAL) {
setFontType(application .getArialFont());
} else if (fontName == FONT_OPEN_SANS) {
setFontType(application .getOpenSans());
}
}
private void setFontType(Typeface font) {
if (fontType == TYPE_BOLD) {
setTypeface(font, Typeface.BOLD);
} else if (fontType == TYPE_ITALIC) {
setTypeface(font, Typeface.ITALIC);
} else {
setTypeface(font);
}
}
}
and in xml
<com.example.customwidgets.TextViewWithFont
font:name="Arial"
font:type="bold"
android:layout_width="wrap_content"
android:text="Hello world "
android:padding="5dp"
android:layout_height="wrap_content"/>
dont forget to add the schema in root of your xml
xmlns:font="http://schemas.android.com/apk/res-auto"
And create an attrs.xml file inside values directory, which is holding our custom attribues:
<?xml version="1.0" encoding="utf-8"?>
<resources>
<declare-styleable name="font">
<attr name="type">
<enum name="bold" value="1"/>
<enum name="italic" value="2"/>
</attr>
<attr name="name">
<enum name="Arial" value="1"/>
<enum name="OpenSans" value="2"/>
</attr>
</declare-styleable>
</resources>
Update:
Found some performance issue when this custom view is used in
listview, that is because the font Object is creating every time the
view is loaded. Solution I found is to initialize the font in Application
Class and refer that font object by
MyApplication application = (MyApplication) getContext().getApplicationContext();
Application class will look like this
public class MyApplication extends Application {
private Typeface arialFont, openSans;
public void onCreate() {
super.onCreate();
arialFont = Typeface.createFromAsset(getAssets(), QRUtils.FONT_ARIAL);
openSans = Typeface.createFromAsset(getAssets(), QRUtils.FONT_OPEN_SANS);
}
public Typeface getArialFont() {
return arialFont;
}
public Typeface getOpenSans() {
return openSans;
}
}
