Question

我在Fragment中有关于MapFragment的问题。在main_layout.xml中：

<android.support.v4.widget.DrawerLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/main_layout"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#ffffff">

<FrameLayout
    android:id="@+id/frame_container"
    android:layout_width="match_parent"
    android:layout_height="match_parent" />

<ListView
    android:id="@+id/list_slidermenu"
    android:layout_width="240dp"
    android:layout_height="match_parent"
    android:layout_gravity="start"
    android:choiceMode="singleChoice"
    android:divider="@color/list_divider"
    android:dividerHeight="1dp"       
    android:listSelector="@drawable/list_selector"
    android:background="@color/list_background"/>

listView是一个菜单，我用它来改变片段。在MainActivity.java中，我通过此函数更改Fragment：

private void displayView(int _position) 
{
    Fragment fragment = null;
    switch (_position) 
    {
        case 0:
            fragment = _YourTravelFragment;
            break;
        case 1:
            fragment = _SettingFragment;
            break;
        default:
            break;
    }

    if (fragment != null) 
    {
        FragmentManager fragmentManager = getFragmentManager();
        fragmentManager.beginTransaction()
                .replace(R.id.frame_container, fragment).commit();
        _DrawerList.setItemChecked(_position, true);
        _DrawerList.setSelection(_position);
        setTitle(_MenuTitles[_position]);
        _DrawerLayout.closeDrawer(_DrawerList);
    } else 
    {
        Log.e("MainActivity", "Error in creating fragment");
    }
}

我创建了两个Fragment，YourTravelFragment和SettingFragment。在fragment_your_travel.xml中有一个MapFragement。因此，当我第一次启动应用程序时，地图正常加载。之后，我使用滑块菜单选择＆＃34; SettingFragment＆＃34;，正常加载SettingFragment，我使用滑块菜单选择＆＃34; YourTravelFragment＆＃34;，并且应用程序有一些错误，它退出。这是＆＃34; YourTravelFragment.java＆＃34;： `私人GoogleMap _GoogleMap; private SupportMapFragment _SupportMapFragment;

public YourTravelFragment()
{
}

@Override
public View onCreateView(LayoutInflater _inflater, ViewGroup _container, Bundle _savedInstanceState) 
{
    View rootView = _inflater.inflate(R.layout.fragment_your_travel, _container, false);
    return rootView;
}

@Override
public void onResume() 
{
    super.onResume();
}

@Override
public void onPause() 
{
    super.onPause();
}

@Override
public void onDestroy() 
{
    super.onDestroy();
}

@Override
public void onLowMemory() 
{
    super.onLowMemory();
}`

错误：

这看起来像是罪魁祸首。 java.lang.IllegalArgumentException: Binary XML file line #5: Duplicate id 0x7f060044, tag null, or parent id 0x0 with another fragment for com.google.android.gms.maps.SupportMapFragment

Fragment中的MapFragment无法修复错误
