The solution would be to have 3 views, one for the first letter, another for the (maximum) two lines, and another for the remainder of the text.
When measuring the view, you can determine if you've passed the 2 lines limit you wish to impose, and if so break the text and set the remainder of the text in the 3rd view.
You would also need to overcome the internal font padding of the first letter in order to achieve your desired result, hence the BottomAlignedTextView view.
Here is the code:
BottomAlignedTextView.java
public class BottomAlignedTextView extends TextView {
public BottomAlignedTextView(Context context) {
super(context);
}
@Override
protected void onDraw(Canvas canvas) {
float offset = getTextSize() - getLineHeight();
canvas.translate(0, -offset);
super.onDraw(canvas);
}
}
