Keylabel of Softkeyboard to change text size and font of keytext

Question

I want to customize softkeyboard. I want to change the text size and font of keytext of keylabel. I have tried many methods but no change in keypad.

You can implement a KeyboardView, then you can customize almost everything in the keyboard's design.

To change de text size you can set the attribute android:keyTextSize.

Unfortunately the isn't a way to change the font style in the xml, you will need to do it programmatically extending a class from KeyboardView. In this case I would suggest Phillip's answer:

public class MyKeyboardView extends KeyboardView {
@Override
public void onDraw(Canvas canvas) {
    Paint paint = new Paint();
    paint.setTextAlign(Paint.Align.CENTER);
    Typeface font = Typeface.createFromAsset(context.getAssets(),
        "fonts/Hippie.otf"); //Insert your font here.
    paint.setTypeface(font);

    List<Key> keys = getKeyboard().getKeys();
    for(Key key: keys) {
        if(key.label != null)
            canvas.drawText(key.label.toString(), key.x, key.y, paint);
        }
    }
}

Another way would be changing your app's font, like Ankush Bist said:

import java.lang.reflect.Field; 
import android.content.Context;
import android.graphics.Typeface;

public final class FontsOverride {

public static void setDefaultFont(Context context,
        String staticTypefaceFieldName, String fontAssetName) {
    final Typeface regular = Typeface.createFromAsset(context.getAssets(),
            fontAssetName);
    replaceFont(staticTypefaceFieldName, regular);
}

protected static void replaceFont(String staticTypefaceFieldName,
        final Typeface newTypeface) {
    try {
           final Field staticField = Typeface.class
                .getDeclaredField(staticTypefaceFieldName);
           staticField.setAccessible(true);
           staticField.set(null, newTypeface);
        } catch (NoSuchFieldException e) {
          e.printStackTrace();
        } catch (IllegalAccessException e) {
        e.printStackTrace();
    }
  }
}

And at last you can fully customize a xml layout like what I did here
