Android 为什么onActivityResult总是返回0，即使按下了ok按钮？

我想实现一个对话框，要求用户决定是否要打开位置wifi和gps，但在ActivityResult上它总是返回0，即使按下ok按钮， 更多详情： 当wifi和gps关闭时，返回0，但两者都已正确激活（按下ok按钮）。 当gps开启和wifi关闭时，返回0，但wifi已正确激活（按下ok按钮）。 仅当wifi打开，gps关闭时，返回-1，但gps正确激活（按下ok按钮）

这是我的代码：

public void activategps(){
        builder = new LocationSettingsRequest.Builder().addLocationRequest(locationRequest);
        builder.setAlwaysShow(true);


        //builder.setNeedBle(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 state = result.getLocationSettingsStates();
                switch (status.getStatusCode()) {
                    case LocationSettingsStatusCodes.SUCCESS:
                        // All location settings are satisfied. The client can initialize location
                        // requests here.
                        //...
                        Log.i("sms", "estan disponibles");
                        Toast.makeText(MainActivity.this, "HOLA 1", Toast.LENGTH_SHORT).show();
                        break;
                    case LocationSettingsStatusCodes.RESOLUTION_REQUIRED:
                        // Location settings are not satisfied. But could be fixed by showing the user
                        // a dialog.
                        Log.i("sms", "Motrando popup");
                     //  if( !state.isNetworkLocationPresent()|| !state.isLocationUsable()){

                            Toast.makeText(MainActivity.this, "HOLA 2", Toast.LENGTH_SHORT).show();
                            try {
                                // Show the dialog by calling startResolutionForResult(),
                                // and check the result in onActivityResult().
                                status.startResolutionForResult(
                                        MainActivity.this,
                                        REQUEST_CHECK_SETTINGS);
                            } catch (SendIntentException e) {
                                // Ignore the error.
                            }
                      // }
                        break;
                    case LocationSettingsStatusCodes.SETTINGS_CHANGE_UNAVAILABLE:
                        Toast.makeText(MainActivity.this, "HOLA 3", Toast.LENGTH_SHORT).show();
                        // Location settings are not satisfied. However, we have no way to fix the
                        // settings so we won't show the dialog.
                        //...
                        break;
                }
            }
        });
    }

我希望你能帮助我，我真的需要它。

呼叫确定按钮位于：case LocationSettings StatusCode.RESOLUTION REQUIRED:，并且两者都在同一个活动中，请查看创建和设置

locationRequest

的代码。您正在测试的设备的API级别是多少？您解决了吗？我在三星Galaxy S3上也遇到了同样的问题。它没有发生在其他人身上，比如：三星S6、小米Redmi note 3……有人解决了这个问题吗？我也有同样的问题。我很久没有使用Android了，但我总是有这样的疑问，所以如果有人对这个解决方案感兴趣，我会很高兴公布答案以帮助其他人。
