How can I scale down my drawable and show a small arrow?

Answer 1

You could use an ImageButton and try android:scaleType

ImageView.ScaleType

Answer 2

I don't hink you can from xml. There's no xml attribute that can do scaling for buttons. You can do it programatically though, in the following way :

Bitmap originalBitmap= BitmapFactory.decodeResource(getResources(), R.drawable.icon);
Bitmap scaledBitmap=Bitmap.createScaledBitmap(originalBitmap, newWidth, newHeight, true);
txt.setBackgroundDrawable(new BitmapDrawable(bit));
