我有以下代码:
protected override void OnCreate (Bundle bundle)
{
progress = ProgressDialog.Show(this, "", "Loading...");
progress.SetProgressStyle(ProgressDialogStyle.Spinner);
base.OnCreate (bundle);
//Set the Activity's view to our list layout
SetContentView(Resource.Layout.LawsAndRegsList);
new Thread(new ThreadStart(() => {
//Create our adapter
listAdapter = new LawsAndRegsListAdapter(this);
this.RunOnUiThread ( () => {
//Find the listview reference
listView = FindViewById<ListView>(Resource.Id.listView);
//Hook up our adapter to our ListView
listView.Adapter = listAdapter;
//Wire up the click event
//listView.ItemClick += new EventHandler<ListView.ItemClickEventArgs>(listView_ItemClick);
listView.ItemClick += listView_ItemClick;
listAdapter.NotifyDataSetChanged();
progress.Dismiss();
});
})).Start();
}
void listView_ItemClick(object sender, AdapterView.ItemClickEventArgs e)
{
//Get our item from the list adapter
var item = this.listAdapter.GetItemAtPosition(e.Position);
//Make a toast with the item name just to show it was clicked
Toast.MakeText(this, item.Name + " Clicked!", ToastLength.Short).Show();
}
谁能告诉我为什么 ItemClick 不会被调用?
它看起来像我读过的和我看过的例子,所以我做错了什么?谢谢您的帮助。
更新:
这是我的两种布局:

更新#2:
添加了我的 LIstAdapter 代码:
公共类 LawsAndRegsListAdapter : BaseAdapter { 活动上下文;
public List<LawsAndRegs> items;
public LawsAndRegsListAdapter (Activity context) //We need a context to inflate our row view from
{
this.context = context;
MY_SEB_SERVICE_ContentWS.ContentWS contentWS = new MY_WEB_SERVICE_ContentWS.ContentWS ();
string sMenu = contentWS.GetMenuXML (146, 1, "", 0, 1033);
XmlRootAttribute r = new XmlRootAttribute ("Item");
var ser = new XmlSerializer (typeof(Item), r);
StringReader stringReader;
stringReader = new StringReader (sMenu);
Item obj = (Item)ser.Deserialize (stringReader);
ItemMenuItem[] m = obj.Menu.Item;
ItemMenuItem larMenu = null;
foreach (ItemMenuItem mnu in m)
{
if (mnu.ItemID == 155)
{
if (this.items == null)
this.items = new List<LawsAndRegs> ();
larMenu = mnu;
break;
}
}
if (larMenu != null)
{
foreach (ItemMenuItemMenuItem imimi in larMenu.Menu.Item)
{
LawsAndRegs lar = new LawsAndRegs();
lar.Name = (string)imimi.Items[2];
lar.Image = (string)imimi.Items[3];
this.items.Add (lar);
}
}
}
public override int Count
{
get { return items.Count; }
}
public override Java.Lang.Object GetItem(int position)
{
return position;
}
public override long GetItemId(int position)
{
return position;
}
public LawsAndRegs GetItemAtPosition(int position)
{
return items[position];
}
public override View GetView(int position, View convertView, ViewGroup parent)
{
//Get our object for this position
var item = items[position];
//Try to reuse convertView if it's not null, otherwise inflate it from our item layout
// This gives us some performance gains by not always inflating a new view
// This will sound familiar to MonoTouch developers with UITableViewCell.DequeueReusableCell()
var view = (convertView ?? context.LayoutInflater.Inflate(Resource.Layout.LawsAndRegsListItem, parent, false)) as LinearLayout;
//Find references to each subview in the list item's view
ImageView imgView = (ImageView)view.FindViewById(Resource.Id.imageItem);
imgView.Clickable = true;
TextView textTop = (TextView)view.FindViewById(Resource.Id.textTop);
textTop.Clickable = true;
var bm = BitmapFactory.DecodeStream(
new Java.Net.URL("http://www.SOME_SITE.com/" + item.Image).OpenStream());
imgView.SetImageBitmap(bm);
//Assign this item's values to the various subviews
textTop.SetText(item.Name, TextView.BufferType.Normal);
view.Clickable = true;
//Finally return the view
return view;
}
}
我添加了 view.clickable 代码以尝试使其正常工作。
