Google Play Services 7.0設置對話框

Question

Google在其blog post中描述了一個單觸設置對話框，要求用戶打開其位置（讓用戶打開位置而不將其發送到手機的設置）。 我只是找不到合適的方法/方法在他們的API文檔中做到這一點。

任何人都已經使用這個，並可以給出解釋？

Answer 2

更具體的，相關的代碼如下

class MainActivity extends Activity implements ResultCallback<LocationSettingsResult> { 
    protected void checkLocationSettings() { 
     PendingResult<LocationSettingsResult> result = 
       LocationServices.SettingsApi.checkLocationSettings(
         mGoogleApiClient, 
         mLocationSettingsRequest 
       ); 
     result.setResultCallback(this); 
    } 

    @Override 
    public void onResult(LocationSettingsResult locationSettingsResult) { 
     final Status status = locationSettingsResult.getStatus(); 
     switch (status.getStatusCode()) { 
      case LocationSettingsStatusCodes.SUCCESS: 
       Log.i(TAG, "All location settings are satisfied."); 
       startLocationUpdates(); 
       break; 
      case LocationSettingsStatusCodes.RESOLUTION_REQUIRED: 
       Log.i(TAG, "Location settings are not satisfied. Show the user a dialog to" + 
         "upgrade location settings "); 
       try { 
        // Show the dialog by calling startResolutionForResult(), and check the result 
        // in onActivityResult(). 
        status.startResolutionForResult(MainActivity.this, REQUEST_CHECK_SETTINGS); 
       } catch (IntentSender.SendIntentException e) { 
        Log.i(TAG, "PendingIntent unable to execute request."); 
       } 
       break; 
      case LocationSettingsStatusCodes.SETTINGS_CHANGE_UNAVAILABLE: 
       Log.i(TAG, "Location settings are inadequate, and cannot be fixed here. Dialog " + 
         "not created."); 
       break; 
     } 
    } 
} 
// This code is from https://github.com/googlesamples/android-play-location/blob/master/LocationSettings/app/src/main/java/com/google/android/gms/location/sample/locationsettings/MainActivity.java 

在LocationSettingsStatusCodes＃RESOLUTION_REQUIRED的結果回調，Status.startResolutionForResult會做的伎倆。
