Question

在地图项上单击两次时片段中的地图在滑动抽屉中崩溃

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

    View rootView = inflater.inflate(R.layout.map_fine_tech, container, false);
    fragment =  getFragmentManager().findFragmentById(R.id.map);
    return rootView;
}

Answer 1

为了避免崩溃，我使用了我在 MyApplication class 中声明的全局变量，它从 Application class

扩展

MyApplication app = (MyApplication) getApplicationContext();
boolean mapstate = app.isMapstate();
String bvalue = String.valueOf(mapstate);
Log.e("tag1", bvalue);
Fragment fragment = null;

switch (position) {
case 0:
    fragment = new UserProfileScreen();
    app.setMapstate(false);
    String c = String.valueOf(mapstate);
    Log.e("case0", c);
    break;
case 1:
    if(mapstate==false)
    {
        fragment = new MapFineTech();
        app.setMapstate(true);
        String bvalue2 = String.valueOf(mapstate);
        Log.e("tag2", bvalue2);
    }
    else
    {

    }
    break;
}
