android - 在 fragment 中开始解析结果

Question

在我的应用程序中，如果用户没有打开位置，我会通过对话框进行提示，然后尝试通过覆盖 Activity 结果来返回该结果(可能是错误的)。

这是在一个 fragment 中，所以不确定它是如何改变的:

这就是我如何将其称为带有 startResolutionForResult 的对话框:

public void checkDeviceLocationIsOn()
        {
            System.out.println("Test running setting request" );
            LocationRequest locationRequest = LocationRequest.create();
            locationRequest.setPriority(LocationRequest.PRIORITY_LOW_POWER);
            LocationSettingsRequest.Builder builder = new LocationSettingsRequest.Builder()
                    .addLocationRequest(locationRequest);
            builder.setAlwaysShow(true); //this is the key ingredient

            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 state = result.getLocationSettingsStates();
                    switch (status.getStatusCode()) {
                        case LocationSettingsStatusCodes.SUCCESS:
                            // All location settings are satisfied.
                            System.out.println("Test setting all fine starting location request" );
                            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(getActivity(), LOCATION_SETTINGS_REQUEST_CODE);
                                System.out.println("Test setting not met starting dialog to prompt user" );
                            } catch (IntentSender.SendIntentException e) {
                                // Ignore the error.
                            }
                            break;
                        case LocationSettingsStatusCodes.SETTINGS_CHANGE_UNAVAILABLE:
                            // Location settings are not satisfied. However, we have no way to fix the
                            // settings so we won't show the dialog.
                            break;
                    }
                }
            });
        }

然后我尝试在它下面得到这样的结果(这永远不会被调用):

   @Override
    public void onActivityResult(int requestCode, int resultCode, Intent data) {
        switch (requestCode) {
        // Check for the integer request code originally supplied to startResolutionForResult().
            case LOCATION_SETTINGS_REQUEST_CODE:
                switch (resultCode) {
                    case Activity.RESULT_OK:
                        System.out.println("test user has turned the gps back on");
                        getLocation();
                        break;
                    case Activity.RESULT_CANCELED:

                        System.out.println("test user has denied the gps to be turned on");
                        Toast.makeText(getActivity(), "Location is required to order stations", Toast.LENGTH_SHORT).show();
                        break;
                }
                break;
        }
    }

预先感谢您的帮助

调用 fragment 方法

startIntentSenderForResult(status.getResolution().getIntentSender(), REQUEST_CODE_LOCATION_SETTING, null, 0, 0, 0, null);

代替

status.startResolutionForResult(...)
