使用GoogleMaps时，应用程序在替换FragmentManager时崩溃了[英] App crashes with FragmentManager Replace when using GoogleMaps

问题描述

I'm using the following code to load fragments depending on which item has been selected on NavigationDrawer, however the MapFragment contains Google Maps fragment inside of it and it crashes after trying to open it for the second time.

Here's the code I'm using:

@Override
    public void onNavigationDrawerItemSelected(int position) {
        // update the main content by replacing fragments
        FragmentManager fragmentManager = getSupportFragmentManager();
        if (position == 0) {
            fragmentManager.beginTransaction()
                    .replace(R.id.container, MapFragment.newInstance("a", "b"))
                    .commit();

        }
        else {
            fragmentManager.beginTransaction()
                    .replace(R.id.container, PlaceholderFragment.newInstance(position + 1))
                    .commit();
        }
    }

And here's the log:

This happens only with the MapFragment. PlaceholderFragment works just fine.

UPDATE

推荐答案

Duplicate ID issue is related to incorrect way of using nested fragments.

From: http://developer.android.com/about/versions/android-4.2.html#NestedFragments

Note: You cannot inflate a layout into a fragment when that layout includes a <fragment>. Nested fragments are only supported when added to a fragment dynamically.

So your fragment_map.xml cannot directly contain com.google.android.gms.maps.MapFragment. Replace it with FrameLayout with id map_container and try something like this:

public class MyFragmentWithMap extends Fragment {

    private MapFragment fragment;
    private GoogleMap map;

    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
        return inflater.inflate(R.layout.fragment_map, container, false);
    }

    @Override
    public void onActivityCreated(Bundle savedInstanceState) {
        super.onActivityCreated(savedInstanceState);
        FragmentManager fm = getChildFragmentManager();
        fragment = (MapFragment) fm.findFragmentById(R.id.map_container);
        if (fragment == null) {
            fragment = MapFragment.newInstance();
            fm.beginTransaction().replace(R.id.map_container, fragment).commit();
        }
    }

    @Override
    public void onResume() {
        super.onResume();
        setUpMapIfNeeded();
    }

    // ...
}

Note the use of getChildFragmentManager.
