推荐答案
这是什么终于为我工作,在这里我使用游标适配器,不只是一个 ArrayListAdapter
我的列表项:
This is what finally worked for me, where I'm using a cursor adapter, not just an ArrayListAdapter
for my list items:
final ListView list = getListView();
for ( int i=0; i< getListAdapter().getCount(); i++ ) {
list.setItemChecked(i, true);
}
list.getChildCount
不工作,因为它似乎只能算什么被立即拉(并非所有的关闭屏幕),所以 childCount
可能只6或8个项目时整个列表是100或更多的项目。另外,作为我不得不使用 list.setItemChecked
获得的项目检查保持 - 至少在我的情况下,我的列表中的项目均 CheckedTextView
。
list.getChildCount
doesn't work because it only seems to count what's been drawn immediately (not everything that's off the screen) so childCount
might only be 6 or 8 items when the entire list is 100 or more items. Also as I had to use list.setItemChecked
to get the items to 'stay checked' -- at least in my case where my list items were instances of CheckedTextView
.
