为什么LocationSettingsResult startResolutionForResult不能调用onActivityResult？ [英] Why is LocationSettingsResult startResolutionForResult not calling onActivityResult?

问题描述

我已经看过这个Q& A LocationSettingsRequest对话框 - onActivityResult（）跳过了。这不是同一个问题，因为所有事情都已经在Activity中完成了。

所使用的代码几乎是逐字的，它是Google Play服务示例中给出的。 p>

我有一个活动， LocationActivity ，它连接到GoogleApiClient以获取用户的位置。连接后，我创建一个 LocationSettingsRequest 以确保打开位置设置。该活动正在执行 ResultCallback< LocationSettingsResult> 。

$ b

ResultCallback< LocationSettingsResult> .onResult ）被调用，如果 result.getStatus（）。getStatusCode（）== LocationSettingsStatusCodes.RESOLUTION_REQUIRED 然后 status.startResolutionForResult这个，REQUEST_CHECK_SETTINGS）被调用，并显示对话框。 无论选择什么问题， onActivityResult（）都不会被调用。

  @Override 
 public void onConnected（Bundle connectionHint）{
 Log.i（TAG，GoogleApiClient connected）; 
 LocationSettingsRequest.Builder builder = new LocationSettingsRequest.Builder（）
 .addLocationRequest（new LocationRequest（）。setPriority（LocationRequest.PRIORITY_LOW_POWER））; 
 
 PendingResult< LocationSettingsResult> result = 
 LocationServices.SettingsApi.checkLocationSettings（googleApiClient，builder.build（））; 
 
 result.setResultCallback（this）; 
} 
  

。

  @Override 
 public void onResult（LocationSettingsResult result）{
 final Status status = result.getStatus（）; 
 Log.d（TAG，onResult（）with：+result = [+ status.getStatusMessage（）+]）; 
 switch（status.getStatusCode（））{
 case LocationSettingsStatusCodes.SUCCESS：
 getLocation（）; 
休息; 
案例LocationSettingsStatusCodes.RESOLUTION_REQUIRED：
 //位置设置不满意。但可以通过显示用户
 //一个对话框来修复。 
 try {
 //通过调用startResolutionForResult（），
 //显示对话框，并在onActivityResult（）中检查结果。 
 status.startResolutionForResult（this，REQUEST_CHECK_SETTINGS）; 
} catch（IntentSender.SendIntentException e）{
 Log.d（TAG，，e）; 
 //忽略错误。 
} 
 break; 
 case LocationSettingsStatusCodes.SETTINGS_CHANGE_UNAVAILABLE：
 showManualInputDialog（）; 
休息; 
} 
} 
  

我永远不会在这里：

  @Override 
 protected void onActivityResult（int requestCode，int resultCode，Intent data）{
 Log.d（TAG，onActivityResult （）调用：+requestCode = [+ requestCode +]，resultCode = [+ resultCode +]，data = [+ data +]）; 
 switch（requestCode）{
 case REQUEST_CODE_RESOLUTION：
 retryConnecting（）; 
休息; 
 case REQUEST_CHECK_SETTINGS：
 if（resultCode == Activity.RESULT_OK）{
 getLocation（）; 
} else {
 showManualInputDialog（）; 
} 
 break; 
默认值：
 super.onActivityResult（requestCode，resultCode，data）; 
休息; 
} 
} 
  

它在我的S3上工作了几次。从我所能告诉它停止工作，当我选择不再问。但是，它从来没有在模拟器或Tab 10上工作，它不再适用于我的S3。

我感到很傻。我的活动在清单中有 noHistory =true，所以当另一个活动开始时，没有东西可以回来。

I've seen this Q&A LocationSettingsRequest dialog - onActivityResult() skipped. It isn't the same issue because everything is being done in an Activity already.

The code used is almost verbatim what is given in the Google Play Services examples.

I have an activity, LocationActivity, that connects to GoogleApiClient for getting the user's location. Once connected I create a LocationSettingsRequest to make sure that location settings are turned on. The activity is implementing ResultCallback<LocationSettingsResult>.

ResultCallback<LocationSettingsResult>.onResult() is called and if result.getStatus().getStatusCode() == LocationSettingsStatusCodes.RESOLUTION_REQUIRED then status.startResolutionForResult(this, REQUEST_CHECK_SETTINGS) is called and the dialog is shown. The problem, no matter what is selected, onActivityResult() is never called.

@Override
public void onConnected(Bundle connectionHint) {
    Log.i(TAG, "GoogleApiClient connected");
    LocationSettingsRequest.Builder builder = new LocationSettingsRequest.Builder()
        .addLocationRequest(new LocationRequest().setPriority(LocationRequest.PRIORITY_LOW_POWER));

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

    result.setResultCallback(this);
}

.

@Override
public void onResult(LocationSettingsResult result) {
    final Status status = result.getStatus();
    Log.d(TAG, "onResult() called with: " + "result = [" + status.getStatusMessage() + "]");
    switch (status.getStatusCode()) {
        case LocationSettingsStatusCodes.SUCCESS:
            getLocation();
            break;
        case LocationSettingsStatusCodes.RESOLUTION_REQUIRED:
            // Location settings are not satisfied. But could be fixed by showing the user
            // a dialog.
            try {
                // Show the dialog by calling startResolutionForResult(),
                // and check the result in onActivityResult().
                status.startResolutionForResult(this, REQUEST_CHECK_SETTINGS);
            } catch (IntentSender.SendIntentException e) {
                Log.d(TAG, "", e);
                // Ignore the error.
            }
            break;
        case LocationSettingsStatusCodes.SETTINGS_CHANGE_UNAVAILABLE:
            showManualInputDialog();
            break;
    }
}

I never get here:

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    Log.d(TAG, "onActivityResult() called with: " + "requestCode = [" + requestCode + "], resultCode = [" + resultCode + "], data = [" + data + "]");
    switch (requestCode) {
        case REQUEST_CODE_RESOLUTION:
            retryConnecting();
            break;
        case REQUEST_CHECK_SETTINGS:
            if (resultCode == Activity.RESULT_OK) {
                getLocation();
            } else {
                showManualInputDialog();
            }
            break;
        default:
            super.onActivityResult(requestCode, resultCode, data);
            break;
    }
}

As an aside. It worked a few times on my S3. From what I can tell it stopped working when I chose to never ask again. But, it hasn't ever worked on an emulator or a Tab 10 and it no longer works on my S3.

解决方案

Well I feel silly. My Activity had noHistory="true" in the Manifest so when the other Activity was started there was nothing to come back to.
