在 ListView 中单击复选框

Question

I have a listview with some text and a checkbox. I can click the checkbox, and the check changes, but when I try to listen for the check being changed, or the click, the listener never triggers.

I have the listview in an Activity (not a ListActivity)

schedule.xml layout:

I'm filling in the data like this:

SimpleAdapter adapter = new SimpleAdapter(this,
            data,
            R.layout.schedulerow,
            new String[] {"Title","Time","Day", "Month"},
            new int[] { R.id.scheduleListTitle, R.id.scheduleListTime,R.id.scheduleListDays, R.id.scheduleListMonths});

listView.setAdapter(adapter);

If I try to add a listener to the checkbox, it does nothing. Any suggestions? I've looked through a TON of sample code and similar questions, and none of it seems to work.

Answer 1

One solution is to forget the list item click listener and use another listener for the rest of the item other than the checkbox.. In item layout xml, put the other views in single layout and set the click listener on this and set the check listener on checkbox as usual. Both will work without issues. Dont use the list item click listener.

class MySimpleAdapter extends SimpleAdapter {
 ... 
   @Override
   void getView(.....) {
       View view = super.getView(.....);
       view.findViewById(R.id.checkboxid).setOnCheckChangedListner(checklistener);
       view.findViewById(R.id.restOfitemview).setOnClickListner(clickListner);
       return view;
    }
}

Define the two listeners and set as shown above.

Edit : First try your method(blocking focus on checkbox) with the MySimpleAdapter setting only the checkchangelistener.. If that does not work then use above solution of dividing the item layout.
