Android Only one item change per fling in gallery
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?
Solution
For that you have to override the onFling method in the Gallery class Try this and just Use ExtendedGallery instead of Gallery
