I have a custom listview in my C# Android app, each row contains a textview, ImageView and a checkbox. When a Listview item is clicked, I want to check the row's item checkbox using bool
value.
MainActivity.cs
List<TableList> list = = new List<TableList>();
list.Add(new TableList("Germany"));
list.Add(new TableList("France"));
list.Add(new TableList("Finland"));
listView.ItemClick += delegate (object sender, AdapterView.ItemClickEventArgs e)
{
string selected = t.Name;
if (selected == "France")
{
Class1.bl = false; // Check the proper checkbox for France row
}
};
Class1.bl
is a static public bool set totrue
ListAdapter and ListClass for the Listview:
public class ListAdapter : BaseAdapter<TableList>
{
List<TableList> items;
Activity context;
public ListAdapter(Activity context, List<TableList> items)
: base()
{
this.context = context;
this.items = items;
}
public override long GetItemId(int position)
{
return position;
}
public override TableList this[int position]
{
get { return items[position]; }
}
public override int Count
{
get { return items.Count; }
}
public override View GetView(int position, View convertView, ViewGroup parent)
{
var item = items[position];
View view = convertView;
if (view == null) // no view to re-use, create new
view = context.LayoutInflater.Inflate(Resource.Layout.CoinList, null);
view.FindViewById<TextView>(Resource.Id.CoinName).Text = item.Name;
view.FindViewById<ImageView>(Resource.Id.imageView1).SetImageResource(Resource.Drawable.n);
if (Class1.bl == false)
{
view.FindViewById<CheckBox>(Resource.Id.checkBox1).Checked = true;
Class1.bl = true;
}
else
{
view.FindViewById<CheckBox>(Resource.Id.checkBox1).Checked = false;
}
return view;
}
}
public class TableList
{
public string Name;
public TableList(string Name)
{
this.Name = Name;
}
}
The above code when I run it, and I select France, the ChechBox
is checked for France but when I check another item like Germany, the ChechBox
for Germany is not checked. Why is this and how can I solve it ?
I have add the bool in your TableList
class:
//I add the bool in this class, so you can change the CheckBox's state by your Data Source
//That means that your CheckBox's state based upon your Data Source.
public class TableList : Java.Lang.Object
{
public TableList(string name, bool b)
{
this.Name = name;
this.bl = b;
}
public string Name { get; set; }
public bool bl { get; set; }
}
I also provide the demo on the github , and here is the result gif.
