You are trying to say you want to hide the checkbox on previously
clicked item and then show it on the currently clicked item? You can
edit it with the getView() method or do something like this
private class UI extends AsyncTask <View, String, View>
{
public View viewItem=null;
public UI(View v)
{
this.viewItem=v;
}
@Override
protected View doInBackground(View... arg0) {
return viewItem;
}
@Override
protected void onPreExecute() {
for(int i = 0; i <= listView.getLastVisiblePosition(); i++)
{
if(listView.getChildAt(i)!= null)
{
(listView.getChildAt(i).findViewById(R.id.yourcheckbox)).setVisibility(View.GONE);
}
}
super.onPreExecute();
}
@Override
protected void onPostExecute(View result) {
((CheckBox)result.findViewById(R.id.yourcheckbox)).setVisibility(View.VISIBLE);
//or change the state of the checkbox, your call :)
super.onPostExecute(result);
}
}
Remember, you can modify your userinterface only from UI thread. So
implementing AsyncTask you should do the modification in
onPreExecute() or in onPostExecute() methods. In your case in
onPreExecute you do hiding on the previous items view child and in
oPostExecute you do showing....
I hope this is what you are looking for.
