MapFragment in ScrollView

Question

I have one of the new MapFragments in a ScrollView. Actually it\'s a SupportMapFragment, but anyway. It works, but there are two problems:

Answer 1

For me adding a transparent ImageView did not help remove the black mask completely. The top and bottom parts of map still showed the black mask while scrolling.

So the solution for it, I found in this answer with a small change. I added,

android:layout_marginTop="-100dp"
android:layout_marginBottom="-100dp"

to my map fragment since it was vertical scrollview. So my layout now looked this way:

To solve the second part of the question I set requestDisallowInterceptTouchEvent(true) for my main ScrollView. When the user touched the transparent image and moved I disabled the touch on the transparent image for MotionEvent.ACTION_DOWN and MotionEvent.ACTION_MOVE so that map fragment can take Touch Events.

ScrollView mainScrollView = (ScrollView) findViewById(R.id.main_scrollview);
ImageView transparentImageView = (ImageView) findViewById(R.id.transparent_image);

transparentImageView.setOnTouchListener(new View.OnTouchListener() {

    @Override
    public boolean onTouch(View v, MotionEvent event) {
        int action = event.getAction();
        switch (action) {
           case MotionEvent.ACTION_DOWN:
                // Disallow ScrollView to intercept touch events.
                mainScrollView.requestDisallowInterceptTouchEvent(true);
                // Disable touch on transparent view
                return false;

           case MotionEvent.ACTION_UP:
                // Allow ScrollView to intercept touch events.
                mainScrollView.requestDisallowInterceptTouchEvent(false);
                return true;

           case MotionEvent.ACTION_MOVE:
                mainScrollView.requestDisallowInterceptTouchEvent(true);
                return false;

           default: 
                return true;
        }   
    }
});

This worked for me. Hope it helps you..
