如何在Android中獲取GPS開關事件？

Question

我有一個簡單的廣播接收器，可以接收GPS的打開/關閉。 當我打開GPS並出現“ Improve accuracy dialog? （開始出現在android 8.0中）由Android框架提供，我兩次收到android.location.PROVIDERS_CHANGED接收器。

以下是我的示例接收器。

public class LocationServicesChangedReceiver extends BroadcastReceiver {

    @Override
    public void onReceive(Context context, Intent intent) {
        Log.i(TAG,"Intent action is "+intent.getExtras());

}

我在清單中聲明如下

<receiver
      android:name=".geofence.core.LocationServicesChangedReceiver"
      android:exported="false">
      <intent-filter>
           <action android:name="android.location.PROVIDERS_CHANGED" />
       </intent-filter>
</receiver>

題：

• 有什么辦法可以停止接收多個onReceive()
• 是否有其他意圖動作來使GPS開啟/關閉事件。

Answer 1

有什么辦法可以停止接收多個onReceive（）：

@Override
public void onReceive(Context context, Intent intent) {
    if (intent.getAction().matches("android.location.PROVIDERS_CHANGED"))
    {
        Log.i(TAG, "Location Providers changed");

        LocationManager locationManager = (LocationManager) context.getSystemService(Context.LOCATION_SERVICE);

        isGpsEnabled = locationManager.isProviderEnabled(LocationManager.GPS_PROVIDER);

        isNetworkEnabled = locationManager.isProviderEnabled(LocationManager.NETWORK_PROVIDER);

        //You receive multiple data from more than one Provider, 
        // choose which one you want to use (GPS or NETWORK Provier).

        if (isGpsEnabled) {
            Log.i(TAG, "Location Providers is GPS");
            // put your code in here to get data from GPS PROVIDER.
        }
        else if (isNetworkEnabled) {
            Log.i(TAG, "Location Providers is Network");
            // put your code in here to get data from NETWORK PROVIDER.
        }

    }
}
