这是我的主要节日？xml version =“1.0”encoding =“utf-8”？＆gt;

<application android:icon="@drawable/icon" android:label="@string/app_name">

<uses-library android:name="com.google.android.maps" />
    <activity android:name=".ShowMap"
              android:label="@string/app_name">
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />
            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
    </activity>

<uses-library android:required="true" android:name="com.google.android.maps"></uses-library>

和main.xml

           <?xml version="1.0" encoding="utf-8"?>
         <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
         android:id="@+id/mainlayout"
         android:orientation="vertical"

         android:layout_height="fill_parent" >

        <com.google.android.maps.MapView
            android:id="@+id/mapview"

             android:layout_height="fill_parent"
             android:enabled="true"
                android:clickable="true"

             android:apiKey="0cHF-o_cvW1DEz3ocWAyybGqUsg8aUlwKMoyr4A"
             />

Answer 1

您是否在AndroidManifest.xml中拥有所需的权限？在我为GPS +地图制作的Android应用中，我有以下内容：

<uses-permission android:name="android.permission.ACCESS_LOCATION" /> 
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />
<uses-permission android:name="android.permission.INTERNET" /> 
<uses-permission android:name="android.permission.ACCESS_GPS" />

Answer 2

这是API密钥的问题。

Here you can do it.

你需要为每个模拟器，设备等生成不同的一个，并为最终版本，你需要将它们与你正在使用的密钥库合并，什么是sux，但没有不同的方式：/。

祝你好运！
