wrong selected count #172

When the parent node is not expanded, androidTreeView.getSelected() cannot get the correct selection when the parent node is checked.

This seems to be a general issue with getting sizes from the tree, root.size is also affected. I solved it by expanding and then collapsing all nodes before the view gets rendered. After that you can check the selected.size successfully, but you still need to count your nodes on your own

I had same issue, but in my case it was, when my menu has more than 2 children trees, so I added such block after the line https://github.com/bmelnychuk/AndroidTreeView/blob/d051ce75f5c9bd5206481808f6133b51f581c8f1/app/src/main/java/com/unnamed/b/atv/sample/holder/SelectableHeaderHolder.java#L48: if(n.getChildren().size()!=0){ for (TreeNode m : n.getChildren()) { getTreeView().selectNode(m, isChecked); } }
