I have a fragment that I need to close when I click away from it, this is the code I have:

@Override
    public boolean dispatchTouchEvent(MotionEvent ev) {
        Rect dialogBounds = new Rect();
        Fragment currentFragment = getSupportFragmentManager().findFragmentById(R.id.fragmentoLeyes);
        if (currentFragment!=null) {
            currentFragment.getView().getHitRect(dialogBounds);
            if (currentFragment instanceof VideoFragment) {
                if (!dialogBounds.contains((int) ev.getX(), (int) ev.getY())) {
                    onBackPressed();
                }
            }
        }
        return super.dispatchTouchEvent(ev);
    }

The problem with the code is that when I click inside the fragment, it closes it and I only need it to close when the click or tap is out of this

The best thing in this case is to overwrite the onTouchEvent() method, by touching the Fragment it detects the coordinates using a Rect :

          Rect r = new Rect(0, 0, 0, 0);
            currentFragment.getView().getHitRect(r);
            boolean  intersects = r.contains((int) event.getX(), (int) event.getY());

and this will determine if you are touching outside the Fragment to proceed to eliminate it.

This would be an example:

@Override
public boolean onTouchEvent (MotionEvent event) {

    if (event.getAction () == MotionEvent.ACTION_DOWN) {

            Rect r = new Rect(0, 0, 0, 0);
            currentFragment.getView().getHitRect(r);
            boolean  intersects = r.contains((int) event.getX(), (int) event.getY());

        if (!intersects) {
            Log.d(TAG, "Pressing INSIDE the Fragment.\nRemoving Fragment!!!");
            FragmentTransaction fragmentTransaction;
            fragmentTransaction = fragmentManager.beginTransaction();
            fragmentTransaction.remove(currentFragment).commit();

            return true;
        }
    }
    return super.onTouchEvent (event);
}
