我的应用程序的一部分需要位置服务,因此如果当前关闭位置,应用程序将提示用户启用它.下面是我正在做它:(也见于这个堆栈溢出的答案)

LocationSettingsRequest.Builder builder = new LocationSettingsRequest.Builder()
            .addLocationRequest(mLocationRequest);
builder.setAlwaysShow(true);

PendingResult<LocationSettingsResult> result = LocationServices.SettingsApi.checkLocationSettings(mGoogleApiClient, builder.build());

result.setResultCallback(new ResultCallback<LocationSettingsResult>() 
{
     @Override
     public void onResult(LocationSettingsResult result) 
     {
         final Status status = result.getStatus();
         final LocationSettingsStates = result.getLocationSettingsStates();
         switch (status.getStatusCode()) 
         {
             case LocationSettingsStatusCodes.SUCCESS:
                 // All location settings are satisfied. The client can initialize location
                 // requests here.
                 ...
                 Log.d("onResult", "SUCCESS");
                 break;
             case LocationSettingsStatusCodes.RESOLUTION_REQUIRED:
                 // Location settings are not satisfied. But could be fixed by showing the user
                 // a dialog.
                 Log.d("onResult", "RESOLUTION_REQUIRED");
                 try …
