SupportMapFragment不起作用，给出错误

Question

当我第一次打开应用程序时，它正确显示地图。但是当我第二次打开应用程序时，它总是崩溃。

@Override 
public void onActivityCreated(Bundle savedInstanceState) { 
    // TODO Auto-generated method stub 
    super.onActivityCreated(savedInstanceState); 

    FragmentManager fm = getChildFragmentManager(); 
    supportMapFragment = (SupportMapFragment)fm.findFragmentById(R.id.doctordetail_map); 

} 

Answer 1

使用此代码，我也面临这样的问题，这会帮助你。

@Override 
public void onActivityCreated(Bundle savedInstanceState) { 
    // TODO Auto-generated method stub 
    super.onActivityCreated(savedInstanceState); 

    FragmentManager fm = getChildFragmentManager(); 
    supportMapFragment = (SupportMapFragment)fm.findFragmentById(R.id.doctordetail_map); 
    if (supportMapFragment == null) { 
     supportMapFragment = SupportMapFragment.newInstance(); 
     fm.beginTransaction().replace(R.id.doctordetail_map, supportMapFragment).commit(); 
    } 

}
