我需要你的帮助...我会一直工作到 3 天。我的应用程序正在处理片段。其中一个片段必须显示来自适用于 Android 的 Google Maps V2 api 的地图。

目前,我正在使用 MapFragment,但毫不奇怪,片段中的片段不是一个好主意,但它可以工作,地图正在显示,我可以编辑它,但是当我切换主片段并返回它时。

原因:java.lang.IllegalArgumentException:二进制 XML 文件第 59 行:重复 id 0x7f070041、标签 null 或父 id 0x7f070040 与 com.google.android.gms.maps.MapFragment 的另一个片段

在 android.app.Activity.onCreateView(Activity.java:4252)

在 android.view.LayoutInflater.createViewFromTag(LayoutInflater.java:673)

这就是我继续处理另一个片段并返回包含地图的片段的原因。我一直在寻找 3 天来解决这个问题,但没有很好的结果。

为了为您恢复,我有一个 Activity 调用一个片段,该片段在布局文件中包含一个 MapFragment。如果您需要更多,请询问:)

谢谢

编辑:这是在主 Activity 中更改 Fragment 的代码

private void swtichFragment(Fragment fragment, Bundle bundle)
{
fragment.setBundle(this, bundle);
FragmentManager fragmentManager = getFragmentManager();
FragmentTransaction fragmentTransaction = fragmentManager.beginTransaction();
fragmentTransaction.replace(R.id.rightFragmentPlaceHolder, fragment);
fragmentTransaction.commit();
mRightFragment = fragment;
}

使用 SupportMapFragment 克服此错误:

在片段布局中

<fragment
android:id="@+id/googleMap"
android:name="com.google.android.gms.maps.SupportMapFragment"
android:layout_width="match_parent"
android:layout_height="match_parent" />

在你的片段 onCreateView

SupportMapFragment mapFragment = (SupportMapFragment) getChildFragmentManager().findFragmentById(R.id.googleMap);

        if (mapFragment != null) {
            mapFragment.getMapAsync(this);
        }

由于您的布局在Fragment's布局中,因此SupportMapFragment是您的片段的子布局。因此getChildFragmentManager()使用Fragment's FragmentManager

在 Fragment 的布局中使用 MapView 而不是 MapFragment。记得调用 MapView 的生命周期方法:

  • onCreate(捆绑)
  • onResume()
  • 暂停()
  • onDestroy()
  • onSaveInstanceState(捆绑)
  • onLowMemory()

如此处所述。

顺便提一句。你不应该使用 MapFragment,只有 SupportMapFragment 和支持库

编辑:

如果您切换到支持库,您可以在此处使用注释 #1 中的代码: http ://code.google.com/p/gmaps-api-issues/issues/detail?id=5064#c1

在片段内显示 MapFragment(NestedFragment):在这一点上我相信你有

  1. 在清单上添加了必要的权限
  2. 将 google play 服务添加为 lib 项目
  3. 清单文件中的 api 键。4.

文档

嵌套片段您现在可以在片段中嵌入片段。这对于您希望将动态且可重用的 UI 组件放入本身是动态且可重用的 UI 组件的各种情况很有用。例如,如果您使用 ViewPager 创建向左和向右滑动并占用大部分屏幕空间的片段,您现在可以将片段插入到每个片段页面中。

要嵌套片段,只需在要添加片段的片段上调用 ​​getChildFragmentManager()。这将返回一个 FragmentManager,您可以像通常从顶级活动中一样使用它来创建片段事务。例如,下面是一些从现有 Fragment 类中添加片段的代码:

片段 videoFragment = new VideoPlayerFragment(); FragmentTransaction 事务 = getChildFragmentManager().beginTransaction(); transaction.add(R.id.video_fragment, videoFragment).commit(); 在嵌套片段中,您可以通过调用 getParentFragment() 获取对父片段的引用。

Android 支持库现在还支持嵌套片段,因此您可以在 Android 1.6 及更高版本上实现嵌套片段设计。

注意:当布局包含 . 仅当动态添加到片段时才支持嵌套片段。

在您的布局文件中

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

在您的片段中 使用片段布局文件onCreate()中引用地图片段childFragmentManager

// Obtain the SupportMapFragment and get notified when the map is ready to be used.
        val mapFragment: SupportMapFragment = childFragmentManager.findFragmentById(R.id.map) as SupportMapFragment
        // Set callback on the fragment
        mapFragment.getMapAsync(this)

需要注意的最重要的一点是,不要将 app.Fragment 与 v4.Fragments 混合使用,否则应用程序会严重崩溃。

            <fragment
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            android:name="com.google.android.gms.maps.SupportMapFragment"
            android:id="@+id/location_map"
            android:layout_above="@id/atmLocation_recyclerView"
            />


View root= inflater.inflate(R.layout.fragment_a_t_m_locations, container, false);
    SupportMapFragment mapFragment = (SupportMapFragment) getChildFragmentManager().findFragmentById(R.id.location_map);
    mapFragment.getMapAsync(googleMap -> {
        mMap=googleMap;
        if(mMap!=null){
            mMap.setMapType(GoogleMap.MAP_TYPE_HYBRID);
        }
    });
