android - Android - SupportMapFragment 与 GoogleMaps API 2.0 给出 IllegalArgumentException

Question

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：

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 Activity 布局文件

<RelativeLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    tools:context=".MainActivity" >

    <Button
        android:id="@+id/showMapButton"

        android:layout_height="wrap_content"
        android:text="Show Map"
        android:layout_marginLeft="30dp"
        android:layout_marginRight="30dp"
        android:layout_marginTop="30dp"
        android:layout_alignParentTop="true" />


    <FrameLayout
        android:id="@+id/allFragmentsFrameLayout"
        android:layout_width="fill_parent"
        android:layout_height="fill_parent"
        android:layout_alignParentTop="true">
        <!-- Put fragments dynamically -->
    </FrameLayout>

</RelativeLayout>

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);
    }
}

地图片段布局

<?xml version="1.0" encoding="utf-8"?>
<fragment
    xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:map="http://schemas.android.com/apk/res-auto"

    </application>

</manifest>

一切都是第一次正常工作。即当我单击Show Map按钮时，地图片段会被加载并显示地图。当我按下返回按钮时，地图片段被卸载，我可以再次看到Show Map按钮。

Show Map再次按下按钮时遇到问题。我收到以下错误：

如果您删除. onDestroyView()不知道这是否是一个适当的解决方案。

public void onDestroyView() {
   super.onDestroyView(); 
   Fragment fragment = (getFragmentManager().findFragmentById(R.id.map));   
   FragmentTransaction ft = getActivity().getSupportFragmentManager().beginTransaction();
   ft.remove(fragment);
   ft.commit();
}

像往常一样给它们充气onCreateView()

public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
    return inflater.inflate(R.layout.map, container, false);
}

您需要使用 getChildFragmentManager() 来添加 SupportMapFragment，而不是通过 xml。

关于“为什么”，见官方文档：http: //developer.android.com/about/versions/android-4.2.html#NestedFragments

使用此解决方案（类似于其他解决方案）：

public void onDestroyView() {

    FragmentManager fm = getActivity().getSupportFragmentManager();
    Fragment fragment = (fm.findFragmentById(R.id.map));

    if (fragment.isResumed()) {
        FragmentTransaction ft = fm.beginTransaction();
        ft.remove(fragment);
        ft.commit();
    }
    super.onDestroyView();
}

在使用 if (fragment.isResumed) 之前我遇到了问题。

当布局包含片段时，您不能将布局膨胀为片段。仅当动态添加到片段时才支持嵌套片段。更多细节在这里！

    if (rootView == null)

当我们尝试加载时，在您的活动原因中使用dialog.SetContentView()方法。onCreate()

再次对话框，它只加载对话框而不是整个活动生命周期，并导致它出现重复 ID 异常。

试试看。

我在 JakeWhartonViewPagerIndicatore 和 SherlockFragments 中遇到了同样的问题。这是解决问题的示例 TestFragment，感谢Natalia提供上述解决方案。你的片段可能和我的有点不同。

我使用了 Natalia 响应，但有时会破坏应用程序。使用这个，它可以完美地工作而不会损坏。

@Override
public void onDestroyView() {

  try{
    FragmentTransaction transaction = getSupportFragmentManager()
            .beginTransaction();

    transaction.remove(nestedFragment);

    transaction.commit();
  }catch(Exception e){
  }

    super.onDestroyView();
}

Fragment fragment = (getChildFragmentManager().findFragmentById(R.id.mapview));
