I am using expandable list view with checkboxex. I need to check all child boxes when i check group checkbox. How to get all child views in group?

public View getGroupView(int groupPosition, boolean isExpanded, View convertView, ViewGroup parent) {

if (convertView == null) {
    LayoutInflater vi = (LayoutInflater) getSystemService(Context.LAYOUT_INFLATER_SERVICE);
    groupRow = vi.inflate(R.layout.season, parent, false);

    groupRow = convertView;
}
TextView seasonTitle = (TextView) groupRow.findViewById(R.id.season_title);
seasonTitle.setText(getGroup(groupPosition).toString());
CheckBox checkBox = (CheckBox) groupRow.findViewById(R.id.season_check_box);


checkBox.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() {
    @Override
    public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {
        ???
    }
});

return groupRow;

}

推荐答案

尝试使用ArrayList中包含布尔对象，这样你可以将它们全部设置为选中，或者全部为未登记的groupcheckbox。

Try using ArrayList containing Boolean objects, this way you can set them all to "checked", or all to "unchecked" with the groupcheckbox.
