Question

我想在我的ListView中以其他颜色制作行 - Xamarin.Android C＃项目。

这是我的代码

ListView DialogoList = (ListView)FindViewById(Resource.Id.DialogoList);
Data data = new Data();
string[] dialogolist = data.Dialogo(Data.level, Data.Lesson);
DialogoList.Adapter = new ArrayAdapter(this, Android.Resource.Layout.SimpleListItem1, dialogolist);

正如@Nongthonbam Tonthoi所说，你可以根据位置覆盖GetView颜色：

例如：

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.CustomView, null);

    view.FindViewById<TextView>(Resource.Id.Text1).Text = item.Heading;
    view.FindViewById<TextView>(Resource.Id.Text2).Text = item.SubHeading;
    view.FindViewById<ImageView>(Resource.Id.Image).SetImageResource(item.ImageResourceId);

    if (position % 2 == 0)
    {
        view.FindViewById<RelativeLayout>(Resource.Id.listView_item_bg).SetBackgroundColor(Color.Pink);
    }
    else
    {
        view.FindViewById<RelativeLayout>(Resource.Id.listView_item_bg).SetBackgroundColor(Color.Blue);
    }
    return view;
}
