我是 android 单声道的新手。我正在尝试制作一个简单的复选框列表,我可以在其中选择我的候选人,按下按钮将它们插入数据库。到这里为止一切都很好,但问题在于加载我的检查值。即使我明确地放了 this.Checked = true;我的复选框也总是未选中
这是我的代码:
加载列表视图:
var CandidatesList = FindViewById<ListView>(Resource.Id.lstVotingCandidates);
CandidatesVoteAdapter cva = new CandidatesVoteAdapter(this, MAE.Code.Utilities.CandidatesInfo.CurrentList);
CandidatesList.ChoiceMode = ChoiceMode.Multiple;
CandidatesList.Adapter = cva;
适配器:
public override View GetView(int position, View convertView, ViewGroup parent)
{
View view = convertView; // re-use an existing view, if one is available
if (view == null) // otherwise create a new one
{
view = new Views.CandidateVoteItemView(context, items[position]);
}
return view;
}
看法:
class CandidateVoteItemView : CheckBox
{
public MAE.MAEService.Candidate Candidate { get; protected set; }
public CandidateVoteItemView(Context context, MAE.MAEService.Candidate candidate) : base(context)
{
this.Text = candidate.FirstName; //Working
this.Checked = true;// (candidate.isChecked == 1) ? true : false;//Not Working
}
}
