Question

I had implemented a custom Gallery with custom Adapter.
My Requirement is that however fast or slow does the user operates fling on the gallery only one item should change in the gallery.
I tried to override the Gallery’s onFling method

@Override
public boolean onFling(MotionEvent e1, MotionEvent e2, float velocityX,
    float velocityY) {
//Log.e("VELOCITY ORIGINAL", ""+velocityX);
if (velocityX > 500) {//moving left
    velocityX = 500.0f;
}else if(velocityX < -500){//moving right
    velocityX = -500.0f;
}
//Log.e("VELOCITY MODIFIED", ""+velocityX);
return super.onFling(e1, e2, velocityX, velocityY);
}

But this did not produce desired results as sometimes it would flick one item and some times it won’t.

Then I tried

@Override
public boolean onFling(MotionEvent e1, MotionEvent e2, float velocityX, float velocityY) {
    return false;
}

But this completely disabled fling operation.

What could be the solution?

Answer 1

For that you have to override the onFling method in the Gallery class Try this and just Use ExtendedGallery instead of Gallery
