小编par*_*rse的帖子

我正在使用MapFragment,我的活动布局是:

<fragment
        android:id="@+id/map"
        android:name="com.google.android.gms.maps.MapFragment"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:layout_below="@+id/actionbar" />

如果我想使用移动地图相机CameraUpdateFactory.newLatLngBounds(LatLngBounds, padding) 我得到此错误:

Map size can't be 0. Most likely, layout has not yet occured for the map view.  Either wait until layout has occurred or use newLatLngBounds(LatLngBounds, int, int, int) which allows you to specify the map's dimensions.

如果地图已经测量,是否有事件监听器？

EDIT1:@raz这是我检索地图片段的代码:

if (googleMap == null) {
            googleMap = ((MapFragment) getFragmentManager().findFragmentById(
                    R.id.map)).getMap();
}
