在服务中生成视图时无法找到片段

Question

我正在尝试实现一个位于所有应用之上的浮动地图视图。

浮动视图的布局。

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent">

<ImageView
    android:id="@+id/bubble"
    android:layout_width="80dp"
    android:layout_height="80dp"
    android:src="@mipmap/ic_launcher"/>

 <RelativeLayout
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:id="@+id/main_overlay_wrapper"
    android:background="@color/colorPrimary"
    android:layout_below="@+id/bubble"
    android:layout_alignParentLeft="true"
    android:layout_alignParentStart="true"
    android:layout_alignParentRight="true"
    android:layout_alignParentEnd="true">

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

   </RelativeLayout>

</RelativeLayout>

我们的想法是更改动画子RelativeLayout的可见性动画，并在那里有一个地图视图。

此布局从服务中膨胀并添加到窗口管理器。

充气时出现以下错误。

注意：将片段复制并粘贴到activity_main.xml

时，不会发生此错误

Answer 1

尝试更改SupportMapFragment ==＆gt; MapFragment

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