应用中有集成Google Map的功能。

在 fragment 使用的时候用的以下方法

xml中

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    ...
    <fragment xmlns:android="http://schemas.android.com/apk/res/android"
        android:id="@+id/frag_map"
        android:name="com.google.android.gms.maps.SupportMapFragment"
        android:layout_width="match_parent"
        android:layout_height="match_parent"/>
      ...
</RelativeLayout>

java代码

private void initMap() {
    FragmentManager fragmentManager = getFragmentManager();
    if (fragmentManager != null) {
        SupportMapFragment mapFragment = (SupportMapFragment) fragmentManager.findFragmentById(R.id.frag_map);
        if (mapFragment != null) {
            mapFragment.getMapAsync(this);
        }
    }
    fusedLocationClient = LocationServices.getFusedLocationProviderClient(activity);
}

在一个fragment中使用时时没有什么问题的，但是当有几个界面当时都用到这个地图功能时，就会出现上面这个问题。

复现路径：打开一个有 SupportMapFragment 的 fragment 界面，能正常加载出地图，切换到顶一个SupportMapFragment的 fragment 界面,就会出现白屏，然后按返回键就会报上面的错误。

然后在 Android 4.2的变更信息文档找到以下信息。fragment 是在 4.2版本添加的。

Note: You cannot inflate a layout into a fragment when that layout includes a <fragment>.
Nested fragments are only supported when added to a fragment dynamically.

fragment 不能加载一个带有<fragment>标签的xml布局，嵌套的fragment需要用以下方式来动态的加载。

Fragment videoFragment = new VideoPlayerFragment();
FragmentTransaction transaction = getChildFragmentManager().beginTransaction();
transaction.add(R.id.video_fragment, videoFragment).commit();

所有文章开头的代码修改为以下就ok了。

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

private void initMap() {
    FragmentManager fragmentManager = getChildFragmentManager();
    SupportMapFragment mapFragment = new SupportMapFragment();
    fragmentManager.beginTransaction().replace(R.id.frag_map, mapFragment).commit();
    mapFragment.getMapAsync(this);
}
