 Hi,

 I have been trying to find a solution for this for the last 3 days but
 i just failed hit a final answer!

 I am creating a View-based class where i show a ball bouncing of the
 sides. I use a Timer to control the animation.

 I want to add a TextView programmatically in my view class. I am
 trying to instantiate an object of TextView with reference to the
 context as follows:

 public class BouncingBallView extends View
 {
 public TextView textView;
 ...

 public BouncingBallView(Context context)
 {
         super(context);
         textView = new TextView(context);
         textView.setTextColor(Color.WHITE);
         textView.setText(test);
         ...

 }

 // Keep in mind that this is called periodically by using a Timer
 @Override protected void onDraw(Canvas canvas)
 {
         // This is not drawn
         textView.draw(canvas);

         // ball drawn correctly
        mBall.setBounds(mX, mY, mX+mBallWidth, mY+mBallHeight);
         mBall.getPaint().setStyle(Paint.Style.STROKE);
         mBall.getPaint().setColor(0x);
         mBall.getPaint().setStrokeWidth(5);
        mBall.draw(canvas);
         mBall.getPaint().setStyle(Paint.Style.FILL);
         mBall.getPaint().setColor(0x);
        mBall.draw(canvas);

 }

 I am trying to do this programmatically as i am not sure if i can do
 it using xml since i alread have created my custom bouncingballview
 and used it as the parameter for setContentView().

 Can any one direct me of how to do this?
 Sorry if this is a trivial question but i am still new to graphics
 handling in Android... i come from Symbian background. If you do know
 of a good introductory article to this topic please share it here.

 Many thanks in advance

Why not put a Layout around your bouncing ball view and then put a
textview inside the layout?
