我正在寻找使用本地sqlite数据库的可扩展列表视图教程。从本地Sqlite数据库填充可扩展ListView
我理解到现在是什么,是以下
private class MyTestList extends SimpleCursorTreeAdapter {
//The below is a constructor with 7 arguments with 3 for parent and 3 for child data ad layout
public MyTestList (Context ctx, Cursor groupCursor, int groupLayout,
String[] groupFrom, int[] groupTo, int childLayout, String[] childFrom,
int[] childTo) {
super(ctx, groupCursor, groupLayout, groupLayout, groupFrom, groupTo, childLayout, childFrom, childTo);
}
我的问题是你如何得到父光标和孩子光标,然后将它们链接到对方。
有一个叫
@Override
protected Cursor getChildrenCursor(final Cursor groupCursor) {
//I suppose here I am passing the parent cursor and then retrieving the
//corresponding child cursor for the particular id ??
NOT SURE HOW DO I FILL THIS, I THINK THIS WILL HAVE SOME STRING ARRAY WITH CHILD DATA
}
这个API后,我应该与UI绑定它,我该怎么做。一直在寻找很久没有找到东西。
