我使用 gms.location.LocationListener （Google Play 服务）来获取用户的位置。它工作正常，但我想检测用户何时禁用或启用他/她的 GPS。 就像这张照片一样。
当我打开/关闭位置时，不会调用任何方法。 当我切换应用程序并返回到我的应用程序时，将调用此方法：
但我需要每当用户打开/关闭位置时调用该事件，我列出的那些事件不会被调用。
Note: With Android API I am able to get those events with onProviderEnabled and onProviderDisabled my problem there is that those events don't get called anymore after I use GoogleApiClient. See picture 2 and 3.
After that onProviderEnabled and onProviderDisabled don't get called well that's another problem I'd like to solve both.

public static class GPSCheck extends BroadcastReceiver {
@Override
public void onReceive(Context context, Intent intent) {
LocationManager locationManager = (LocationManager) context.getSystemService(context.LOCATION_SERVICE);
if(locationManager.isProviderEnabled(LocationManager.GPS_PROVIDER)) {

} else {
Log.d("BUHOO", " :( GPS TURNED OFF !!!!!!!!!!!!!!!!!!!");

}
}
您可以通过设置广播接收器每当您设备的 GPS 打开/关闭时就会触发
Steps:
1. 首先创建一个扩展BroadcastReceiver的GPS类
public class GPSCheck extends BroadcastReceiver{
@Override
public void onReceive(Context context, Intent intent) {
LocationManager locationManager = (LocationManager) context.getSystemService(context.LOCATION_SERVICE);
if(locationManager.isProviderEnabled(LocationManager.GPS_PROVIDER))
{
}
else
{
Toast.makeText(context, "Please switch on the GPS", Toast.LENGTH_LONG).show();
}
}
}
2.然后在你的AndroidManifest.xml文件中提及这个类
<receiver android:name="com.yourpackagename.example.GPSCheck" >
<intent-filter>
<action android:name="android.location.PROVIDERS_CHANGED" />
<category android:name="android.intent.category.DEFAULT" />
</intent-filter>
</receiver>
3.不要忘记添加此权限
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />
