Detecting thumb position in SeekBar prior to API version 16

Question

Basically, I need to detect when the progress changes in the SeekBar and draw a text view on top of the thumb indicating the progress value.

I do this by implementing a

I was able to use my own class to get the Thumb:

MySeekBar.java

package mobi.sherif.seekbarthumbposition;

import android.content.Context;
import android.graphics.drawable.Drawable;
import android.util.AttributeSet;
import android.widget.SeekBar;

public class MySeekBar extends SeekBar {

    public MySeekBar(Context context) {
        super(context);
    }
    public MySeekBar(Context context, AttributeSet attrs) {
        super(context, attrs);
    }
    public MySeekBar(Context context, AttributeSet attrs, int defStyle) {
        super(context, attrs, defStyle);
    }

    Drawable mThumb;
    @Override
    public void setThumb(Drawable thumb) {
        super.setThumb(thumb);
        mThumb = thumb;
    }
    public Drawable getSeekBarThumb() {
        return mThumb;
    }

}

In the activity this works perfectly:

package mobi.sherif.seekbarthumbposition;

import android.app.Activity;
import android.graphics.Rect;
import android.os.Bundle;
import android.util.Log;
import android.widget.SeekBar;
import android.widget.SeekBar.OnSeekBarChangeListener;

public class MainActivity extends Activity implements OnSeekBarChangeListener {
    MySeekBar mSeekBar;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        mSeekBar = (MySeekBar) findViewById(R.id.seekbar);
        mSeekBar.setOnSeekBarChangeListener(this);
    }
    @Override
    public void onProgressChanged(SeekBar seekBar, int progress, boolean b) {
        Rect thumbRect = mSeekBar.getSeekBarThumb().getBounds();
        Log.v("sherif", "(" + thumbRect.left + ", " + thumbRect.top + ", " + thumbRect.right + ", " + thumbRect.bottom + ")");
    }
    @Override
    public void onStartTrackingTouch(SeekBar seekBar) {
        // TODO Auto-generated method stub

    }
    @Override
    public void onStopTrackingTouch(SeekBar seekBar) {
        // TODO Auto-generated method stub

    }
}
