我想在我的 android 应用程序中显示谷歌地图应用程序:
我做了android开发人员中提到的步骤:https ://developers.google.com/maps/documentation/android/start
但是它在我的应用程序中为我显示,一个带有缩放(加号和减号按钮)的棕色屏幕,没有地图本身(它没有向我显示任何错误)
我创建了这个 xml 文件:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical" >
<ImageView
android:id="@+id/itemImage"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_marginLeft="10dp"
android:layout_marginRight="10dp"
android:src="@drawable/logo" />
<RelativeLayout
android:layout_width="fill_parent"
android:layout_height="400dp"
android:layout_marginTop="10dp"
android:layout_weight="66496.79"
android:orientation="horizontal" >
<fragment
android:id="@+id/map"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:name="com.google.android.gms.maps.MapFragment"/>
</RelativeLayout>
</LinearLayout>
这是我的清单文件:
