我如何检测用户是否禁用GPS（Android - Play Services）

Question

我使用gms.location.LocationListener（Google Play Services）获取用户的位置。它工作正常，但我想要检测每当用户禁用或启用他/她的GPS。 正如在这张照片中。

当我打开ON/OFF位置没有方法被调用。 当我切换应用程序，并返回到我的应用程序这种方法被称为：

• 在onStart
• 的onResume
• onConnected

但我需要的情况下，每当用户打开被称为/关闭位置我列出的这些事件不会被调用。

注意：使用Android API，我可以使用onProviderEnabled和onProviderDisabled获取这些事件，我的问题是在使用GoogleApiClient之后，这些事件不再被调用。见图2和3. 之后，onProviderEnabled和onProviderDisabled不好调用这是另一个问题，我想解决这两个问题。

• 的Android 1.5.1工作室
• 测试中的Galaxy Note 3（SM-N900W8的是Android 5.0，API 21）

} 

Answer 1

你可以通过设置一个广播接收器来实现这一点， henever设备的GPS开启/关闭

步骤：

1.首先创建一个类GPS延伸广播接收器

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.再提到这一点在AndroidManifest.xml中的类文件

<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也

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