import android.widget.ImageView;

public class ArrowImageView extends ImageView{

    public ArrowImageView(Context context) {
        super(context);
    }

    @Override
    public void draw(Canvas canvas) {
        super.draw(canvas);

        Paint paint  = new Paint(Paint.LINEAR_TEXT_FLAG);
        paint.setColor(Color.GREEN);
        paint.setTextSize(12.0F);
        canvas.drawText("Hello World in custom view", 100, 100, paint);
    }
}
