How to set Gesture properties dynamically
GestureOverlayView gestures = (GestureOverlayView) findViewById(R.id.GestureTest);
    gestures.addOnGesturePerformedListener(handleGestureListener);
    Button check=(Button)findViewById(R.id.checkit);
    check.setOnClickListener(new OnClickListener()
    {
        @Override
        public void onClick(View v)
        {
            gestures.setFadeOffset(1000);
        }
    });
}
