我正在使用expandablelistview。我必须默认将组listview扩展为4。有可能实现这一目标吗?
最佳答案
您可以在组列表视图中定义固定值,如下所示:
private void prepareListData() {
listDataHeader = new ArrayList<String>();
listDataChild = new HashMap<String, List<String>>();
// Adding parent data
listDataHeader.add("first");
listDataHeader.add("second");
listDataHeader.add("third");
listDataHeader.add("fourth");
// Adding child data
List<String> first = new ArrayList<String>();
first.add("The Shawshank Redemption");
first.add("The Godfather");
first.add("The Godfather: Part II");
first.add("Pulp Fiction");
first.add("The Good, the Bad and the Ugly");
first.add("The Dark Knight");
first.add("12 Angry Men");
List<String> second = new ArrayList<String>();
second.add("The Conjuring");
second.add("Despicable Me 2");
second.add("Turbo");
second.add("Grown Ups 2");
second.add("Red 2");
second.add("The Wolverine");
List<String> third = new ArrayList<String>();
third.add("2 Guns");
third.add("The Smurfs 2");
third.add("The Spectacular Now");
third.add("The Canyons");
third.add("Europa Report");
listDataChild.put(listDataHeader.get(0), first); // Header, Child data
listDataChild.put(listDataHeader.get(1), second);
listDataChild.put(listDataHeader.get(2), third);
}
