android.view.InflateException：二进制 XML 文件第 14 行：膨胀 class 片段时出错

Question

当我单击后退按钮并返回到位置片段时遇到了一些问题，出现以下错误：

我确实检查了很多 post 并尝试了所有解决方案，但它不起作用。好像其他菜单项都没有问题，只有这个位置页面报错。

fragment_location.xml

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

<Spinner
    android:id="@+id/spinner1"
    android:layout_width="match_parent"
    android:layout_height="40dp"
    android:background="@color/white"
    android:spinnerMode="dropdown"/>

<fragment
    android:id="@+id/map"
    android:name="com.google.android.gms.maps.SupportMapFragment"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:layout_marginTop="40dp"/>

</RelativeLayout>

LocationFragment.java

    @Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
                         Bundle savedInstanceState) {

        view = inflater.inflate(R.layout.fragment_location, container, false);// this is the line 73
        SupportMapFragment mapFragment = (SupportMapFragment) getChildFragmentManager().findFragmentById(R.id.map);
        mapFragment.getMapAsync(this);

    return view;
}

Answer 1

我认为主要原因是您使用名称而不是 class、

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

尝试更新此代码库。

  FragmentManager fmanager = getSupportFragmentManager();
   Fragment fragment = fmanager.findFragmentById(R.id.map);
        SupportMapFragment supportmapfragment = (SupportMapFragment)fragment;
        GoogleMap supportMap = supportmapfragment.getMap()

您正在使用 childSupportmanager ，还有这一行 view = inflater.inflate(R.layout.fragment_location, container, false); 您从未从中锚定您的地图视图，例如 view.findViewVyId 您从未这样做过

Answer 2

尝试在 LocationFragment.java 中删除 onDestroyView 上的 mapFragment。

@Override
public void onDestroyView() {
    super.onDestroyView();
    SupportMapFragment mapFragment = (SupportMapFragment) getChildFragmentManager().findFragmentById(R.id.map);
    if (mapFragment != null)
        getChildFragmentManager().beginTransaction().remove(mapFragment).commitAllowingStateLoss();
}
