Google Maps Android API V2 blacking out part of layout

Question

I\'m trying to integrate Google Maps Android API v2 into my Android Application. I\'m placing the Google Map in the middle of my layout. It works great when the layout is able t

My workaround: make use of the new snapshot interface from GoogleMap and display a snapshot of the map while scrolling the page.

Here is my code to setting the snapshot (it's in the same fragment as map, called FragmentMap.java):

public void setSnapshot(int visibility) {
    switch(visibility) {
    case View.GONE:
        if(mapFragment.getView().getVisibility() == View.VISIBLE) {
            getMap().snapshot(new SnapshotReadyCallback() {
                @Override
                public void onSnapshotReady(Bitmap arg0) {
                    iv.setImageBitmap(arg0);
                }
            });
            iv.setVisibility(View.VISIBLE);
            mapFragment.getView().setVisibility(View.GONE);
        }
        break;
    case View.VISIBLE:
        if(mapFragment.getView().getVisibility() == View.GONE) {
            mapFragment.getView().setVisibility(View.VISIBLE);
            iv.setVisibility(View.GONE);
        }
        break;
    }
}

Where "mapFragment" is my SupportedMapFragment and "iv" is an ImageView (make it match_parent).

And here I am controlling the scroll:

pager.setOnPageChangeListener(new OnPageChangeListener() {
        @Override
        public void onPageScrolled(int position, float positionOffset, int positionOffsetPixels) {
            if(position == 0 && positionOffsetPixels > 0 || position == 1 && positionOffsetPixels > 0) {
                ((FragmentMap)adapter.getRegisteredFragment(1)).setSnapshot(View.GONE);
            } else if(position == 1 && positionOffsetPixels == 0) {
                ((FragmentMap)adapter.getRegisteredFragment(1)).setSnapshot(View.VISIBLE);
            }
        }
        @Override
        public void onPageScrollStateChanged(int arg0) {}
        @Override
        public void onPageSelected(int arg0) {}
    });

My fragment with map (FragmentMap) is on position 1, so I need to controll the scroll from position 0 to 1 and from position 1 to 2 (the first if-clause). "getRegisteredFragment()" is a function in my custom FragmentPagerAdapter, in which I have a SparseArray(Fragment) called "registeredFragments".

So, whenever you scroll to or from your map, you always see a snapshot of it. This works very well for me.
