android - 带有 fragment 的重复 ID

Question

我正在尝试应用 drawernavigation(我的第一个 fragment 是 map ，其他 fragment 只是一些具有简单布局的 fragment )。所以它运行良好并且我可以在我的 fragment 之间导航但是当我返回到第一个 fragment 时一张 map 我撞车了

我认为这是最重要的:

Duplicate id 0x7f05000c, tag null, or parent id 0xffffffff with another fragment for com.google.android.gms.maps.MapFragment

所以这是我的代码:LoginScreen:一个fragmentActivity，它对 fragment 进行所有调用

这是 fragmentActivity 的主要布局:

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

    <!-- Framelayout to display Fragments -->
    <FrameLayout
        android:id="@+id/frame_container"
        android:layout_width="match_parent"
        android:layout_height="match_parent" >

   </FrameLayout>

    <!--     

<fragment
  android:id="@+id/map"
  android:layout_width="match_parent"
  android:layout_height="match_parent"
  class="com.google.android.gms.maps.MapFragment"/>

     -->

    <!-- Listview to display slider menu -->
    <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"/>

</android.support.v4.widget.DrawerLayout>

这是 mapfragment 的 xml 布局:

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

    <fragment
  android:id="@+id/map"
  android:layout_width="match_parent"
  android:layout_height="match_parent"
  class="com.google.android.gms.maps.MapFragment"/>

</RelativeLayout>

这是 map fragment 代码:

public class HomeFragment extends Fragment {


      int mCurrentPosition = -1;
MapFragment mMap;
    GoogleMap googleMap;
    final static String ARG_POSITION = "position";

    public HomeFragment(){}

            }
        View rootView = inflater.inflate(R.layout.fragment_map, container, false);
//        int status = GooglePlayServicesUtil.isGooglePlayServicesAvailable(getApplicationContext());

         // Set article based on saved instance state defined during onCreateView
         updateArticleView(mCurrentPosition);

我认为问题出在 onResume 和 onCreateView 方法上!! 希望你能帮助我谢谢。

Answer 1

使用这个

<fragment
        android:id="@+id/map"
        android:name="com.google.android.gms.maps.SupportMapFragment"
        android:layout_width="fill_parent"
        android:layout_height="fill_parent"
        android:clickable="true"
         />

并覆盖方法 onDestroyView() 并将此代码放入 onDestroyView()

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