我有问题在Android片段上膨胀Mapbox MapView.当我在Activity上使用相同的代码时(除了Activity和Fragment之间的标准差异),我可以正确加载MapView,但不能在Fragment上加载.
Mapbox 在这里也有一个MapFragment类,但我不确定如何在Fragment中正确使用它(该示例仍然在Activity中); 使用Google Maps API,我可以在片段上使用MapView而不会出现问题.
下面的logcat行:
at com.example.exampleapp.FragmentMap.onCreateView(FragmentMap.java:133)
是指Java行:
fragmentLayout = inflater.inflate(R.layout.fragment_map, container, false);
以下是此问题的相关代码以及日志:
fragment_map.xml:
FragmentMap.java:
public class FragmentMap extends Fragment {
private MapView mv, miniMap;
View fragmentLayout;
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
fragmentLayout = inflater.inflate(R.layout.fragment_map, container, false);
mv = (MapView) fragmentLayout.findViewById(R.id.mapview);
mv.onCreate(savedInstanceState);
miniMap = (MapView) fragmentLayout.findViewById(R.id.mini_map);
miniMap.onCreate(savedInstanceState);
return fragmentLayout;
}
@Override
public void onStart() {
super.onStart();
mv.onStart();
miniMap.onStart();
}
@Override
public void onStop() {
super.onStop();
mv.onStop();
miniMap.onStop();
}
@Override
public void onDestroy() {
super.onDestroy();
mv.onDestroy();
miniMap.onDestroy();
}
@Override
public void onResume() {
super.onResume();
mv.onResume();
miniMap.onResume();
}
@Override
public void onPause() {
super.onPause();
mv.onPause();
miniMap.onPause();
}
@Override
public void onLowMemory() {
super.onLowMemory();
mv.onLowMemory();
miniMap.onLowMemory();
}
@Override
public void onSaveInstanceState(Bundle outState) {
super.onSaveInstanceState(outState);
mv.onSaveInstanceState(outState);
miniMap.onSaveInstanceState(outState);
}
logcat的:
