Clear all selected items in a gridview

I have a gridview inside a ExpandableListView with CHOICE_MODE_MULTIPLE, I'm trying to deselect all items when I press a button, but the way I'm doing it it is only unselecting the last item, how can I clear all of them?

@Override public int getCount() { return child.size(); } @Override public Object getItem(int position) { return position; } @Override public long getItemId(int arg0) { return 0; } @Override public View getView(final int position, View convertView, ViewGroup parent) { holder = null; if (convertView == null) { LayoutInflater inflater = (LayoutInflater) mContext .getSystemService(Context.LAYOUT_INFLATER_SERVICE); convertView = inflater.inflate(R.layout.child_item, null); holder = new ViewHolder(); holder.text = (TextView) convertView.findViewById(R.id.name); convertView.setTag(holder); final View finalConvertView = convertView; convertView.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View v) { isChecked = child.get(position).isChecked(); if (!isChecked) { child.get(position).setChecked(true); } else { child.get(position).setChecked(false); } ex.findViewById(R.id.notificar).setOnClickListener(new View.OnClickListener() { @Override public void onClick(final View v) { //clear all selected items for(int i = 0; i< getCount(); i++){ child.get(i).setChecked(false); } } }); } else { holder = (ViewHolder) convertView.getTag(); } holder.text.setText(child.get(position).getNome()); return convertView; } } } static class ViewHolder { TextView text; }

-------------Problems Reply------------

Try calling listView.clearChoices(); and adapter.notifyDataSetChanged(); from the activity or fragment containing the list, not inside the adapter.

Your problem is using calling child.size first, it is returning 1.
You are getting the child count from a different view.

@Override
public int getCount() {
return child.size();
}

If you call child.size() within you OnClickListener where you are using the

public void onClick(final View v) {

You should be iterating through the array adapter of the list, as the child.counts of the view will be different from the number of checked list items, if the list is scrollable. As there will be less items in the view (they are recycled) than within the list.
