Question

像我这样在我的项目上实施googlemap

来自xml

<fragment
        android:id="@+id/map"
        android:layout_width="match_parent"
        android:layout_height="250dp"
        class="com.google.android.gms.maps.MapFragment"/>

来自java的

public class Search extends Fragment implementsOnMapReadyCallback {
    View rootView;

    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {

...
loadMap();
...
}

GoogleMap map;
MapFragment mapFragment;

    public void loadMap() {
        if (mapFragment == null) {
            mapFragment = (MapFragment) getFragmentManager().findFragmentById(R.id.map);
            mapFragment.getMapAsync(this);
        }
    }

@Override
    public void onMapReady(GoogleMap googleMap) {
        map = googleMap;
        map.setMyLocationEnabled(true);
        map.getUiSettings().setZoomControlsEnabled(true);
    }

@Override
    public void onDestroy() {
        super.onDestroy();
        getFragmentManager().beginTransaction().remove(mapFragment).commit();
    }

即使我从一个片段更改为另一个片段，这也能正常工作。但是，经过一段时间后，就像应用程序已经在后台运行了很长时间，当我再次尝试打开应用程序时，它只是崩溃应用程序而我收到此错误

我该如何解决这个问题。

Answer 1

我认为这个错误可以忽略，app应该加载得很好。试试这个：

View rootView;

public View onCreateView(LayoutInflater inflater,
                             ViewGroup container, Bundle savedInstanceState)
    {
        // The last two arguments ensure LayoutParams are inflated
        // properly.
        if (rootView != null)
        {
            ViewGroup parent = (ViewGroup) rootView.getParent();
            if (parent != null)
                parent.removeView(rootView);
        }

        try
        {
            rootView = inflater.inflate( R.layout.yourMapFragment, container, false );
        }
        catch( InflateException ex )
        {
        }

        ...
        return rootView;
    }

应用程序在后台被杀死后，MapFragment崩溃
