mono for android加载远程图片

废话不多说了，直接上代码Main.axml

<?xml version="1.0" encoding="utf-8"?><LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"    android:orientation="vertical"    android:layout_width="fill_parent"    android:layout_height="fill_parent"    android:background="#fff">    <ImageView        android:id="@+id/showPic"        android:layout_width="400px"        android:layout_height="400px" /></LinearLayout>

MainActivity.cs

[Activity(Label = "Learning1", MainLauncher = true)]    public class MainActivity : Activity    {        private ImageView showPic;        private string picPath = "http://www.kl.cc/images/about/tizi/jiangkun/inscription-jiangkun.jpg";        ProgressDialog msgbox;        protected override void OnCreate(Bundle bundle)        {            base.OnCreate(bundle);            SetContentView(Resource.Layout.Main);            showPic = FindViewById<ImageView>(Resource.Id.showPic);            msgbox = ProgressDialog.Show(this, "请稍等", "图片正在加载中...", true, true);                       HttpWebRequest req = WebRequest.Create(picPath) as HttpWebRequest;            req.Method = "Get";            req.GetResponseAsync().ContinueWith(o =>            {                              HttpWebResponse resp = (HttpWebResponse)o.Result;                              this.RunOnUiThread(() =>                {                    Drawable dr = new BitmapDrawable(resp.GetResponseStream());                    showPic.SetImageDrawable(dr);                    msgbox.Cancel();                });            });        }    }
