Android Button events doesn't work with touch events

Question

I use example with zoom and scrool big image, which use GestureDetector code here . When I place button on it, I cannot handle any button events - both onClickListener, OnTouchListener doesn't fired.

public class ScrollableView extends AbsoluteLayout  implements OnGestureListener, OnDoubleTapListener { 
private GestureDetector mGestureDetector; 
private ImageView mImageView; 
private Context mContext; 
Button mZoomIn;

public ScrollableView(Context context) { 
    super(context); 
    mContext = context;
    mZoomIn = new Button(context);
    mZoomIn.setText("OK");  
            RelativeLayout.LayoutParams startparam = new RelativeLayout.LayoutParams(
            RelativeLayout.LayoutParams.WRAP_CONTENT,
            RelativeLayout.LayoutParams.WRAP_CONTENT);
    startparam.addRule(RelativeLayout.ALIGN_PARENT_BOTTOM);
    mZoomIn.setOnClickListener(
            new View.OnClickListener() {
                @Override
                public void onClick(View v) {
                    // TODO Auto-generated method stub
                    Toast.makeText(mContext, "Click!", Toast.LENGTH_SHORT); 
                }       
    });
        this.addView(mZoomIn); 
       mGestureDetector = new GestureDetector(this); 
}

What is my mistake?

Missing a .show from the end of Toast.makeText?
