android - map 仅在其 Activity 为 Launcher Activity 时加载

Question

当它不是启动器 Activity 时， map Activity 不工作我还必须从应用程序标签中删除 name=MyApplication 以使其工作。如果我从其他类(class)打开 Activity ，但不会加载 map 。

在布局文件中试试这个:

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

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


</RelativeLayout>
