Question

我正在尝试在我正在开发的Android应用程序上实现google map api v2，对于java类我正在扩展Fragment，因为我正在使用导航抽屉。

问题是：当您尝试从导航栏中点击它时，谷歌地图将首次运行，但是当您第二次再次点击它时它会崩溃。

这是java类：

public class FindUs_fragment extends Fragment{
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
        Bundle savedInstanceState) {

    View layout= (View)inflater.inflate(R.layout.map_activity, container,false);

    return layout;
}

这是xml文件：

    <?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical" >
    <fragment

        xmlns:map="http://schemas.android.com/apk/res-auto"
        android:id="@+id/map"
        android:name="com.google.android.gms.maps.MapFragment"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
    map:cameraZoom="15"/>

</LinearLayout>

这是清单文件：

<?xml version="1.0" encoding="utf-8"?>

    package="com.application.example"
    android:versionCode="1"

    <application

        android:icon="@drawable/ic_launcher"

        android:theme="@style/AppTheme" >
        <activity
            android:name="com.application.example.MainActivity"
            android:label="@string/app_name"
            android:screenOrientation="portrait" >
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />

                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>

        <meta-data
            android:name="com.google.android.gms.version"
            android:value="@integer/google_play_services_version" />
        <meta-data
            android:name="com.google.android.maps.v2.API_KEY"
            android:value="api key" />
    </application>

</manifest>

我可以知道导致应用崩溃的问题是什么？

感谢您的时间。

@Dimmerg：我将FindUs_fragment附加到导航抽屉，以下是导航抽屉活动的代码：

public class MainActivity extends Activity {

    private String[] drawerListViewItems;
    private ListView drawerListView;
    private DrawerLayout drawerlayout;
    private ActionBarDrawerToggle actionbardrawertoggle;
    Fragment fragment = null;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        drawerListViewItems = getResources().getStringArray(R.array.drawer_item);
        drawerListView = (ListView)findViewById(R.id.left_drawer);

        drawerListView.setAdapter(new ArrayAdapter<String>(this, R.layout.drawer_listview_item, drawerListViewItems));
        drawerlayout = (DrawerLayout)findViewById(R.id.drawer_layout);

        actionbardrawertoggle = new ActionBarDrawerToggle(
                this,
                drawerlayout,
                R.drawable.ic_drawer, 
                R.string.drawer_open, 
                R.string.drawer_close
                );
        drawerlayout.setDrawerListener(actionbardrawertoggle);
        getActionBar().setDisplayHomeAsUpEnabled(true);
        if (savedInstanceState == null) {
            // on first time display view for first nav item
            displayView(0);
        }
        drawerListView.setOnItemClickListener(new DrawerItemClickListener());



    }

    @Override
    protected void onPostCreate(Bundle savedInstanceState) {
        // TODO Auto-generated method stub
        super.onPostCreate(savedInstanceState);
        actionbardrawertoggle.syncState();
    }

    @Override
    public void onConfigurationChanged(Configuration newConfig) {
        // TODO Auto-generated method stub
        super.onConfigurationChanged(newConfig);
        actionbardrawertoggle.onConfigurationChanged(newConfig);
    }

    @Override
    public boolean onOptionsItemSelected(MenuItem item) {
        // TODO Auto-generated method stub

        if(actionbardrawertoggle.onOptionsItemSelected(item))
        {
            return true;
        }
        return super.onOptionsItemSelected(item);
    }

    @Override
    public boolean onCreateOptionsMenu(Menu menu) {
        // Inflate the menu; this adds items to the action bar if it is present.
        getMenuInflater().inflate(R.menu.main, menu);
        return true;
    }

    private class DrawerItemClickListener implements ListView.OnItemClickListener
    {

        @Override
        public void onItemClick(AdapterView<?> parent, View view, int position,
                long id) {
            // TODO Auto-generated method stub
            displayView(position);
            //drawerlayout.closeDrawer(drawerListView);
        }

    }

    private void displayView(int position)
    {
        Fragment fragment = null;
        switch (position) {
        case 0:
            fragment = new Home_fragment();
            break;

        case 1:
            fragment = new FindUs_fragment();
            break;   

        case 3:
            fragment = new Facebook_fragment();
            break;


        default:
            break;
        }

        if (fragment != null) {
            FragmentManager fragmentManager = getFragmentManager();
            fragmentManager.beginTransaction()
                    .replace(R.id.content_frame, fragment).commit();

            // update selected item and title, then close the drawer
            drawerListView.setItemChecked(position, true);
            drawerListView.setSelection(position);
            setTitle(drawerListViewItems[position]);
            drawerlayout.closeDrawer(drawerListView);
        } else {
            // error in creating fragment
            Log.e("MainActivity", "Error in creating fragment");
        }
    }
    }

在重新加载之前，您需要将谷歌地图设为null。这对我有用。

@Override
public void onDestroyView() {
    SupportMapFragment f = (SupportMapFragment) getFragmentManager()
            .findFragmentById(id);
    if (f != null) {
        try {
            getFragmentManager().beginTransaction().remove(f).commit();
        } catch (Exception e) {
            e.printStackTrace();
        }
    }
    if (mMap != null) {
        List<Marker> temp = mMap.getMarkers();
        if (temp != null) {
            for (Marker marker : temp) {
                marker.remove();
                marker = null;
            }
        }
    }
    mMap = null;
    super.onDestroyView();

}
