我一直在努力完成这项工作并找到了许多解决方案，但都没有奏效。 listview中不会触发click事件。此外，活动的触摸事件也不会被触发。我已经在布局中添加了android：descendantFocusability =“blocksDescendants”，但这没有帮助。这是我的代码：
主要活动：
protected override void OnCreate (Bundle bundle)
{
base.OnCreate (bundle);
RequestWindowFeature(WindowFeatures.Progress);
RequestWindowFeature(WindowFeatures.IndeterminateProgress);
// Set our view from the "main" layout resource
SetContentView (Resource.Layout.Main);
lv = FindViewById<ExpandableListView> (Resource.Id.lvItems);
FooterView = new TextView (this);
lv.AddFooterView (FooterView);
FooterView.Text = "Fling Velocity: ";
lv.ChoiceMode = ChoiceMode.Multiple;
lv.Clickable = true;
lv.Focusable = true;
lv.FocusableInTouchMode = true;
//lv.Touch += (object sender, View.TouchEventArgs e) => {this.OnTouchEvent(e.Event); e.Handled = false;};
//_gestureDetector = new GestureDetector(this);
//_ScaleGestureDetector = new ScaleGestureDetector (this,this);
System.Collections.Generic.List<ImgFolder> BMList = new System.Collections.Generic.List<ImgFolder>();
System.Diagnostics.Debug.Print (Android.OS.Environment.GetExternalStoragePublicDirectory(Android.OS.Environment.DirectoryPictures).Path);
string selection = null;
string[] selectionArgs = null;
string[] projection = new string[] {MediaStore.MediaColumns.Id, MediaStore.MediaColumns.Data,
MediaStore.Images.Media.InterfaceConsts.BucketDisplayName, MediaStore.Images.Media.InterfaceConsts.BucketId
};
Android.Database.ICursor mediaCursor = ContentResolver.Query(Android.Provider.MediaStore.Images.Media.ExternalContentUri,
projection, selection,selectionArgs, null);
lib.GetThumbnails (this,false,mediaCursor, BMList);
mediaCursor = ContentResolver.Query(Android.Provider.MediaStore.Images.Media.InternalContentUri,projection,selection,selectionArgs, null);
lib.GetThumbnails (this,true,mediaCursor, BMList);
//ArrayAdapter Adapter = new ArrayAdapter<ImgListItem>(this,Android.Resource.Layout.ActivityListItem,BMList);
PhotoFolderAdapter Adapter = new PhotoFolderAdapter (this, BMList);
lv.SetAdapter (Adapter);
lv.ItemClick += lv_ItemClick;
/* (object sender, AdapterView.ItemClickEventArgs e) => {
View v = e.View;
if (v.Tag != null) {
ViewHolder holder = (ViewHolder)(v.Tag);
ImgListItem ImgListItem = holder.item;
lib.StartViewer (this, ImgListItem.Uri);
}
};
*/
///new EventHandler<AdapterView.ItemClickEventArgs>(lv_ItemClick);
}
private void lv_ItemClick(object sender, AdapterView.ItemClickEventArgs e)
{
View v = e.View;
if (v.Tag != null) {
ViewHolder holder = (ViewHolder)(v.Tag);
ImgListItem ImgListItem = holder.item;
lib.StartViewer (this, ImgListItem.Uri);
}
}
适配器：
public override View GetChildView(int groupPosition, int childPosition, bool isLastChild, View convertView, ViewGroup parent)
{
// Recycle a previous view if provided:
View view = convertView;
// If no recycled view, inflate a new view as a simple expandable list item 2:
if (view == null)
{
view = context.LayoutInflater.Inflate(Resource.Layout.CustomView,null);
}
ImgListItem item = rows [groupPosition].items[childPosition];
ImageView Image = view.FindViewById<ImageView> (Resource.Id.Image);
Image.SetImageBitmap (item.Img);
Image.Clickable = false;
Image.Focusable = false;
Image.FocusableInTouchMode = false;
Image.LongClickable = false;
//Image.Click+= (object sender, EventArgs e) => Console.WriteLine("IMG clicked");
//view.FindViewById<ImageView> (Android.Resource.Id.Icon).ScaleX = 5;
//view.FindViewById<ImageView> (Android.Resource.Id.Icon).ScaleY = 5;
TextView Text1 = view.FindViewById<TextView> (Resource.Id.Text1);
Text1.Text = item.FileName;
Text1.Clickable = false;
Text1.Focusable = false;
Text1.FocusableInTouchMode = false;
Text1.LongClickable = false;
//Text1.Click+= (object sender, EventArgs e) => Console.WriteLine("Text1 clicked");
if (item.Img != null) {
TextView Text2 = view.FindViewById<TextView> (Resource.Id.Text2);
Text2.Text = (item.size != null) ? item.size : item.Img.Width + "*" + item.Img.Height;
Text2.Clickable = false;
Text2.Focusable = false;
Text2.FocusableInTouchMode = false;
Text2.LongClickable = false;
//Text2.Click += (object sender, EventArgs e) => Console.WriteLine("Text2 clicked");
}
//if (item.Img != null) view.FindViewById<TextView> (Resource.Id.Text2).Text = (item.size != null) ? item.size : item.Img.Width + "*" + item.Img.Height;
//view.FindViewById<TextView> (Android.Resource.Id.Text1).
view.Tag = new ViewHolder(item);
//view.ScaleX = 2;
//view.ScaleY = 2;
view.Clickable = false;
view.Focusable = false;
view.FocusableInTouchMode = false;
view.LongClickable = false;
/*view.Click += (object sender, EventArgs e) => {
System.Diagnostics.Debug.Print ("Click");
};
*/
//view.Touch += new EventHandler<View.TouchEvent1Args> (touch);
return view;
}

答案 0 :(得分：1)
在我看来，ItemClick事件并未在monodroid中实现。使用ChildClick事件可以正常工作。
