android L怎么实现增加群组功能，最好是源码，谢谢！！

此代码为实现android L增加群组功能Location功能的简单封装。

package arui.csdn.net;

源码打印?

import static

}

private static final LocationListener mLocationListener = new

public void onLocationChanged(Location location) {

// 当坐标改变时触发此函数，如果Provider传进相同的坐标，它就不会被触发

System.out.println("onLocationChanged:" + location.getLatitude());

}

public void onProviderDisabled(String provider) {

// Provider被disable时触发此函数，比如GPS被关闭

System.out.println("onProviderDisabled:" + provider);

}

public void onProviderEnabled(String provider) {

// Provider被enable时触发此函数，比如GPS被打开

System.out.println("onProviderEnabled:" + provider);

}

public void onStatusChanged(String provider, int status, Bundle extras)
{

// Provider的转态在可用、暂时不可用和无服务三个状态直接切换时触发此函数

System.out.println("onStatusChanged:" + status);

}

};

}

需要增加权限：

android:name="android.permission.ACCESS_FINE_LOCATION" />

android:name="android.permission.ACCESS_COARSE_LOCATION" />
