本文介绍如何使用高德地图API实现Android应用中的位置定位功能。通过代码示例展示了必要的地图视图配置及定位权限设置，同时实现了定位监听器以获取实时位置更新。

<com.amap.api.maps.MapView
xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/map"
android:layout_width="match_parent"

android:layout_height="match_parent" />

//地图包、搜索包需要的基础权限

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

<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />

<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />

<uses-permission android:name="android.permission.ACCESS_WIFI_STATE" />

<uses-permission android:name="android.permission.READ_PHONE_STATE" />

<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" />

//定位包、导航包需要的额外权限（注：基础权限也需要）

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

<uses-permission android:name="android.permission.ACCESS_LOCATION_EXTRA_COMMANDS" />

<uses-permission android:name="android.permission.ACCESS_MOCK_LOCATION" />

<uses-permission android:name="android.permission.CHANGE_WIFI_STATE" />

//此方法为每隔固定时间会发起一次定位请求，为了减少电量消耗或网络流量消耗，
//注意设置合适的定位时间的间隔，并且在合适时间调用removeUpdates()方法来取消定位请求
//在定位结束后，在合适的生命周期调用destroy()方法
//其中如果间隔时间为-1，则定位只定一次
mLocationManagerProxy.requestLocationData(
LocationProviderProxy.AMapNetwork,-1, 15, this);
mLocationManagerProxy.setGpsEnable(false);
mapView = (MapView) findViewById(R.id.map);
mapView.onCreate(savedInstanceState);// 必须要写
aMap = mapView.getMap();
}

@Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.activity_main, menu);
return true;
}

@Override
protected void onDestroy() {
// TODO Auto-generated method stub
super.onDestroy();
mLocationManagerProxy.destroy();

@Override

Log.e("TGA","地址"+arg0.toString());
Log.e("TGA","地址"+arg0.getAMapException().getErrorCode());
