使用真机测试,模拟器无法定位
效果图:
1.首先是权限:
<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" />
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />
<uses-permission android:name="android.permission.READ_PHONE_STATE" />
<uses-permission android:name="android.permission.CHANGE_WIFI_STATE" />
<uses-permission android:name="android.permission.ACCESS_WIFI_STATE" />
<uses-permission android:name="android.permission.CHANGE_CONFIGURATION" />
<uses-permission android:name="android.permission.WAKE_LOCK" />
<uses-permission android:name="android.permission.WRITE_SETTINGS" />
<application
android:allowBackup="true"
android:icon="@mipmap/ic_launcher"
android:label="@string/app_name"
android:supportsRtl="true"
android:theme="@style/AppTheme">
<activity android:name=".MainActivity">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
android:configChanges="orientation|keyboardHidden|screenSize"
</activity>
<!--记得写入keystore-->
<meta-data
android:name="com.amap.api.v2.apikey"
android:value="从高德官网的到的key值" />
<!-- 定位需要的服务 使用2.0的定位需要加上这个 -->
<service android:name="com.amap.api.location.APSService"></service>
</application>
具体获取key值的方法可以参照官网的文档
:http://lbs.amap.com/api/android-location-sdk/guide/create-project/get-key
复制key的地方:
2.布局文件

android:id="@+id/activity_main"
