Question

Activity.RESULT_CANCELED (value == 0 )始终会在onActivityResult()中被调用，即使在位置对话框上按“确定”

如果在设备设置中关闭了位置，我将向用户显示位置对话框。

使用了以下代码-

                LocationSettingsRequest.Builder builder = new LocationSettingsRequest.Builder();
                builder.addLocationRequest(new LocationRequest().setPriority(LocationRequest.PRIORITY_HIGH_ACCURACY));
                builder.setAlwaysShow(true);
                mLocationSettingsRequest = builder.build();

                mSettingsClient = LocationServices.getSettingsClient(WifiList_Activity.this);

                mSettingsClient
                        .checkLocationSettings(mLocationSettingsRequest)
                        .addOnSuccessListener(new OnSuccessListener<LocationSettingsResponse>() {
                            @Override
                            public void onSuccess(LocationSettingsResponse locationSettingsResponse) {
                                //Success Perform Task Here
                            }
                        })
                        .addOnFailureListener(new OnFailureListener() {
                            @Override
                            public void onFailure(@NonNull Exception e) {
                                int statusCode = ((ApiException) e).getStatusCode();
                                switch (statusCode) {
                                    case LocationSettingsStatusCodes.RESOLUTION_REQUIRED:
                                        try {
                                            ResolvableApiException rae = (ResolvableApiException) e;
                                           rae. startResolutionForResult(WifiList_Activity.this, REQUEST_CHECK_SETTINGS);
                                        } catch (IntentSender.SendIntentException sie) {
                                            Logger.log("GPS Unable to execute request.");
                                        }
                                        break;
                                    case LocationSettingsStatusCodes.SETTINGS_CHANGE_UNAVAILABLE:
                                        Logger.log("GPS Location settings are inadequate, and cannot be fixed here. Fix in Settings.");
                                }
                            }
                        });

onActivityResult()中的代码如下，

@Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
    super.onActivityResult(requestCode, resultCode, data);
    if (requestCode == REQUEST_CHECK_SETTINGS) {
        switch (resultCode) {

            case Activity.RESULT_CANCELED:
                Logger.log("Result code in onACtivityresult CANCELED::"+resultCode);
                Logger.log("GPS User denied to access location");
                finish();
                break;


            case Activity.RESULT_OK:
                //Success Perform Task Here
                Logger.log("Result code in onACtivityresult OK::"+resultCode);
                break;
        }
  }

但是问题是，即使用户在“位置”对话框上按“确定”，由于接收到的resultCode为0，总是会调用Acivity.RESULT_CANCELED。

我已将应用定位到Android Q，

compileSDKVersion "android-Q'
targetSDKVersion 'Q'

此外，在Pixel设备上的Android Q beta上运行该应用。

预期-按下确定对话框时，resultCode -1应该为   返回onActivityResult。

实际-即使按ok，也将返回resultCode 0   onActivityResult。
