Google位置服务与Android位置服务

Question

我们知道我们有两个替代方案可以让我们的应用程序位置知道我们使用Google的位置服务API(Google Play服务的一部分),或者我们使用Androids Location API.

我在这里遇到的问题是,使用Google的服务,我们必须使用com.google.android.gms.location.LocationListener接口为我们提供位置更新.然而,与android.location.LocationListener不同,谷歌的版本并没有'为我们提供位置提供者的状态(gps或互联网).

我们在Androids Location Listener中有以下方法

abstract void   onLocationChanged(Location location)
Called when the location has changed.
abstract void   onProviderDisabled(String provider)
Called when the provider is disabled by the user.
abstract void   onProviderEnabled(String provider)
Called when the provider is enabled by the user.
abstract void   onStatusChanged(String provider, int status, Bundle extras)
Called when the provider status changes

.

但是在谷歌我们只有一个

abstract void   onLocationChanged(Location location)

如果我使用谷歌服务,我如何识别提供商的变化？.例如,在应用程序使用中,用户决定关闭GPS,我想在此事件上显示祝酒词.

我在黑暗中如何实现这一点.

您注册一个接收器来处理活动Providers_changed.

private static final String ACTION_GPS = "android.location.PROVIDERS_CHANGED";
private BroadcastReceiver yourReceiver;

private void checkGPS() {
    Context context = this.getApplicationContext();
    if (context != null) {
        Button btnGPS = (Button) findViewById(R.id.btnGPS);
        if (btnGPS != null) {
            LocationManager locationManager = (LocationManager) context
                    .getSystemService(Context.LOCATION_SERVICE);
            boolean b = locationManager
                    .isProviderEnabled(LocationManager.GPS_PROVIDER);
            locationManager = null;
            if (b) {
                if (btnGPS.getVisibility() != View.GONE) {
                    btnGPS.setVisibility(View.GONE);
                }
            } else {
                if (btnGPS.getVisibility() != View.VISIBLE) {
                    btnGPS.setVisibility(View.VISIBLE);
                }
            }
        }
    }
}

private void registerReceiverGPS() {
    if (yourReceiver == null) {
        // INTENT FILTER FOR GPS MONITORING
        final IntentFilter theFilter = new IntentFilter();
        theFilter.addAction(ACTION_GPS);
        yourReceiver = new BroadcastReceiver() {
            @Override
            public void onReceive(Context context, Intent intent) {
                if (intent != null) {
                    String s = intent.getAction();
                    if (s != null) {
                        if (s.equals(ACTION_GPS)) {
                            checkGPS();
                        }
                    }
                }
            }
        };
        registerReceiver(yourReceiver, theFilter);
    }
}


 @Override
 public void onResume() {
 super.onResume();
 checkGPS();
 registerReceiverGPS();



    @Override
public void onStop() {
    super.onStop();
    // Do not forget to unregister the receiver!!!
    if (yourReceiver != null) {
        unregisterReceiver(yourReceiver);
        yourReceiver = null;
    }
