Question

我正在使用CheckLocationSettings来检查位置是否已启用。这在我的Galaxy S5上工作正常。但是，在模拟器android kitkat 4.4上，无论位置是启用还是禁用，LocationSettingsResult始终为6（ResolutionRequired）。如果我用YES回答位置请求弹出窗口，则OnActivityResult始终为RESULT_CANCELED

我正在使用xamarin，所以有些部分看起来不同：

protected void buildGoogleApiClient()
        {
            mGoogleApiClient = new GoogleApiClient.Builder(this)
           .AddConnectionCallbacks(this)
           .AddOnConnectionFailedListener(this)
           .AddApi(LocationServices.API)
           .Build();
        }

        protected void createLocationRequest()
        {
            mLocationRequest = new LocationRequest();

            mLocationRequest.SetInterval(UPDATE_INTERVAL_IN_MILLISECONDS);

            mLocationRequest.SetFastestInterval(FASTEST_UPDATE_INTERVAL_IN_MILLISECONDS);

            mLocationRequest.SetPriority(LocationRequest.PriorityLowPower);
        }

        protected void buildLocationSettingsRequest()
        {
            LocationSettingsRequest.Builder builder = new LocationSettingsRequest.Builder();
            builder.AddLocationRequest(mLocationRequest);
            builder.SetAlwaysShow(true);
            mLocationSettingsRequest = builder.Build();
        }

        protected async Task CheckLocationSettings()
        {
            var result = await LocationServices.SettingsApi.CheckLocationSettingsAsync(
                mGoogleApiClient, mLocationSettingsRequest);
            await HandleResult(result);
        }


        public async Task HandleResult(LocationSettingsResult locationSettingsResult)
        {
            var status = locationSettingsResult.Status;
            switch (status.StatusCode)
            {
                case CommonStatusCodes.Success:
                    await getlastknownlocation();
                    break;
                case CommonStatusCodes.ResolutionRequired:

                    try
                    {
                        status.StartResolutionForResult(this, REQUEST_CHECK_SETTINGS);
                    }
                    catch (IntentSender.SendIntentException)
                    {

                    }
                    break;
                case LocationSettingsStatusCodes.SettingsChangeUnavailable:
                    break;
            }
        }


                protected override async void OnActivityResult(int requestCode, Result resultCode, Intent data)
        {
            switch (requestCode)
            {
                case REQUEST_CHECK_SETTINGS:
                    switch (resultCode)
                    {
                        case Result.Ok:
                            await getlastknownlocation();
                            break;
                        case Result.Canceled:
                            break;
                    }
                    break;
            }
        }

如果您获得RESOLUTION_REQUIRED（C＃：ResolutionRequired），则需要请求用户许可。

状态代码RESOLUTION_REQUIRED表示必须更改设置。要提示用户修改位置设置的权限，请调用startResolutionForResult（Activity，int）。此方法会显示一个对话框，要求用户修改位置设置。

使用您可以在StartResolutionForResult中检查的结果代码调用OnActivityResult，以确定用户是否授予了权限：

if (status.StatusCode == LocationSettingsStatusCodes.ResolutionRequired)
{
    status.StartResolutionForResult(this, 9999);
}
