Android v2 MapFragment shaking when scrolling in Scrollview

Question

I am using the SupportMapFragment to display a static map in a ScrollView. I do not like to move / zoom the Map, just showing where the location is.

When I am scrol

Answer 1

With the new release of the Google Play Services, Google added a snapshot method in order to retrieve a Bitmap of the currenrt shown map, which instead may be shown. So interaction is not possible but at leased the map is not shaking anymore.

use

GoogleMap.snapshot (GoogleMap.SnapshotReadyCallback callback)

and implement the SnapshotReadyCallback. Once the Snapshot is delivered, replace the MapFragment with an ImageView containing the Snapshot.

This example works pretty well in the onResume method:

@Override
    public void onResume() {
        super.onResume();
        notifyDataChanged();
        final ViewTreeObserver viewTreeObserver = fragmentMap.getView()
                .getViewTreeObserver();

        if (viewTreeObserver.isAlive()) {
            viewTreeObserver
                    .addOnGlobalLayoutListener(new OnGlobalLayoutListener() {

                        @Override
                        public void onGlobalLayout() {
                            onMesuredMap(this);
                        }
                    });
        }

    }

    private void onMesuredMap(OnGlobalLayoutListener listener) {
        if (fragmentMap.getView().getWidth() != 0
                && fragmentMap.getView().getHeight() != 0) {

            fragmentMap.getView().getViewTreeObserver()
                    .removeOnGlobalLayoutListener(listener);

            makeSnapShot();
        }
    }

        private void makeSnapShot() {
    Runnable action = new Runnable() {
        @Override
        public void run() {

            fragmentMap.getMap().snapshot(new SnapshotReadyCallback() {

                @Override
                public void onSnapshotReady(Bitmap arg0) {
                    imageViewStaticMap.setImageBitmap(arg0);
                    removeMapFragment();
                }

            });
        }
    };
            //litle hack to make sure that the map is loaded for sure
    fragmentMap.getView().postDelayed(action, 1500);
}

    private void removeMapFragment() {
        if (fragmentMap.isVisible()) {
            getChildFragmentManager()
                    .beginTransaction()
                    .remove(fragmentMap)
                    .commit();
        }
    }

Sidenote: To use the new release run an Update of the Android SDK Manager, and when using maven run the maven-android-sdk-deployer with:

mvn install -fae
