我想在将结果输入OStateUserId对象后运行此语句.

details.Text = OStateUserID.name + "\n" + OStateUserID.population);

bStateuserID.Click +=  async delegate 
{
    details.Text=" ";
    Guid x = new Guid("33F8A8D5-0DF2-47A0-9C79-002351A95F88");
    state OStateUserID =(state) await obj.GetStateByUserId(x.ToString());
    details.Text = OStateUserID.name + "\n" + OStateUserID.population);
};

GetStateByUserId()方法返回一个对象class State.

它以异步方式运行.完成操作后,我想将名称和填充分配给TextView详细信息.

我RunOnUIThread()在这种情况下如何使用？

我的便携式类库中有以下代码.但它给出了错误

System.Net.HttpWebRequest不包含的定义 GetResponse().

public async Task<object> GetStateByUserId(string userID)
    {
        HttpWebRequest request;
        Stream receiveStream;
        StreamReader readStream;

        request =(HttpWebRequest)CreateGetWebRequest("state/uid/"+userID);
        using (HttpWebResponse response = (HttpWebResponse)request.GetResponse()) {

        receiveStream = response.GetResponseStream ();
        readStream = new StreamReader(receiveStream);
        string str = readStream.ReadToEnd().ToString();
        s = JsonConvert.DeserializeObject<state>(str);
            return s;
        }


    }

谁知道为什么会这样？

我正在使用MvvmCross来创建PCL.在我的Android应用程序中,我创建了一个名为itemc.axml的ItemTemplate的mvx.mvxListView.文件itemc.axml在Layout文件夹中创建,但仍然会出现此错误.错误 - 找不到与给定名称匹配的资源(在'MvxItemTemplate'处,值为'@ layout/itemc')

为什么？

我的FirstView.axml文件如下

          <?xml version="1.0" encoding="utf-8"?>
           <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
                    xmlns:local="http://schemas.android.com/apk/res/constD.Droid"
                    android:orientation="vertical"
                    android:layout_width="fill_parent"
                    android:layout_height="fill_parent">
                    <Button
                             android:text="Show Constituencies"
                             android:layout_width="match_parent"
                             android:layout_height="wrap_content"
                             android:id="@+id/button1" />
                    <Mvx.MvxListView
                             android:layout_width="fill_parent"
                             android:layout_height="fill_parent"
                             local:MvxBind="ItemsSource Result"
                             local:MvxItemTemplate="@layout/itemc" />
             </LinearLayout>

我的itemc.axml文件如下.

     <?xml version="1.0" encoding="utf-8"?>
     <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
        xmlns:local="http://schemas.android.com/apk/res-auto"
             android:orientation="vertical"
             android:layout_width="fill_parent"
             android:layout_height="fill_parent">
             <TextView
                      android:layout_width="fill_parent"
                      android:layout_height="wrap_content"
                      android:textSize="40dp"
                      local:MvxBind="Text name" />
    </LinearLayout>

为什么会这样？

   I have one custom object in my ViewModel.I want to bind only one of its member to textview in my droid view.

我想只绑定该对象的字符串成员到textview目前我正在这样做.

   local:MvxBind = "Text Myobject.ItsMember"

好吗？还是我错了？

或者我可以这样做吗？

   local:MvxBind = "ItemsSource MyObject ; Text ItsMember"

我怎样才能做到这一点？

当我的edittext获得焦点时,我想显示软键盘.我写了以下代码来做到这一点.但是,尽管我的edittext正在获得焦点,但仍然没有出现键盘.

   private void VerifyCodeEditText_FocusChange(object sender, View.FocusChangeEventArgs e)
    {
        if(e.HasFocus)
        {
            var inputManager = (InputMethodManager)GetSystemService(Context.InputMethodService);
            inputManager.ShowSoftInput(VerifyCodeEditText, ShowFlags.Implicit);
        }
    }

我正在使用MvvmCross创建PCL.我在Command中调用一个方法,通过调用Web服务来获取数据.我想异步执行此数据获取操作.如何在Command中应用异步和等待方法？

有任何想法吗？

我想将流数据从响应流转换为自定义对象.

我想将respose流转换为自定义对象,我正在执行这些步骤.

我的代码如下.

myMethod()               
{
    state s = new state();
    Stream receiveStream;
    StreamReader readStream;
    HttpWebRequest request;
    HttpWebResponse response;
    try
    {
        request = (HttpWebRequest)WebRequest.Create (url);
        request.Method = "GET";  
        request.ContentType = "application/json";
        response = (HttpWebResponse)request.GetResponse ();
        receiveStream = response.GetResponseStream();

        readStream = new StreamReader(receiveStream);
        Console.WriteLine (readStream.ReadToEnd());
        serializer = new DataContractJsonSerializer(typeof(state));
        s = serializer.ReadObject(readStream.BaseStream)as state;
        Console.Write(s.name+"\n"); 

        response.Close ();
        readStream.Close ();    

    }
    catch (Exception ex)
    {
    }
}

对象š返回什么.谁能帮我？
