How can I interact with the ball?
My problem is:
I draw some balls by code and then I want to detect a click on it. I think that the same as John problem

I notice that you do not return a boolean in the onTouch method? I’m confused.

Very good tutorial! I changed a bit in order to have a for loop set up a series of circles. I need each circle to have a onClickListener. Any help would be appreciated.

Hi, I am just trying to draw 6 balls on the screen using this code.
I am doing this:
mainLayout.addView(new Ball(this,50,50,25,0));
mainLayout.addView(new Ball(this,100,50,25,1));
mainLayout.addView(new Ball(this,150,50,25,2));
mainLayout.addView(new Ball(this,200,50,25,3));
mainLayout.addView(new Ball(this,250,50,25,4));
mainLayout.addView(new Ball(this,300,50,25,5));

but it only adds the first ball and not the others. If I comment out the first one, then only the 2nd will be drawn, and so on.
Any idea why this is happening??
