我正在尝试使用为 Android 提供的最新 Map API 2.0.我正在使用支持库，因为我想支持 Android 2.2.以下是我的代码:
I am trying to use the latest Map API 2.0 provided for Android. I am using the Support Library as I want to support Android 2.2. Following is my code:
主要活动类
public class MainActivity extends FragmentActivity {
public FragmentManager fManager ;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
fManager = getSupportFragmentManager();
Button showMapButton = (Button) findViewById(R.id.showMapButton);
showMapButton.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
loadMapFragment();
}
});
}
private void loadMapFragment() {
MapPageFragment plotterFragment = new MapPageFragment();
FragmentTransaction ft = fManager.beginTransaction();
ft.replace(R.id.allFragmentsFrameLayout, plotterFragment);
ft.addToBackStack(null);
ft.commit();
}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
getMenuInflater().inflate(R.menu.activity_main, menu);
return true;
}
}
主活动布局文件

地图片段类
public class MapPageFragment extends SupportMapFragment {
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
super.onCreateView(inflater, container, savedInstanceState);
return inflater.inflate(R.layout.map_fragment_layout, container, false);
}
@Override
public void onViewCreated(View view, Bundle savedInstanceState) {
super.onViewCreated(view, savedInstanceState);
}
}

第一次一切正常.即当我点击 Show Map 按钮时，地图片段被加载并显示地图.当我按下 back 按钮时，地图片段被卸载，我可以再次看到 Show Map 按钮.
Everything is working fine for the first time. i.e. When I click on the Show Map button the map fragment gets loaded and displays the map. When I press back button, the map fragment is unloaded and I can see the Show Map button again.
当我再次按下 Show Map 按钮时，我遇到了一个问题.我收到以下错误:
I face an issue when I press the Show Map button again. I get the following error:

我不知道哪里出错或遗漏了任何东西.
I am not getting where I am getting wrong or missing anything.
推荐答案
如果你删除 onDestroyView() 中的所有嵌套片段，你可以解决这个问题.不知道是不是合适的解决方案.
You can fix this, if you delete all nested fragments in onDestroyView(). Don't know if it is a proper solution.
public void onDestroyView() {
super.onDestroyView();
Fragment fragment = (getFragmentManager().findFragmentById(R.id.map));
FragmentTransaction ft = getActivity().getSupportFragmentManager().beginTransaction();
ft.remove(fragment);
ft.commit();
}
并像往常一样在 onCreateView()
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
return inflater.inflate(R.layout.map, container, false);
}
