LatLngBounds.Builder builder = new LatLngBounds.Builder();
            for (LatLng latLng : mLocations) {
                builder.include(latLng);
            }
            MapStatusUpdate mapStatusUpdate = MapStatusUpdateFactory.newLatLngBounds(builder.build());
            mBaiduMap.setMapStatus(mapStatusUpdate);
            MapStatusUpdate msu = MapStatusUpdateFactory.zoomBy(-0.8f);
            mBaiduMap.setMapStatus(msu);
 

應該在onMapLoaded回撥後使用。
