2. Key code initNode function
public void initNode(){

@Override
public void onAddItem(NodeBean nodeBean) {

}
3. Notification refresh refresh function.
public void refresh(){
// Remove the old TreeHeaderView
if (adapter != null) {
adapter.removeHeaderView(treeHeaderView);
}
//Create and add a new TreeHeaderView
treeHeaderView = new TreeHeaderView(mActivity, dataList);
treeHeaderView.setOnCheckedChangeListener(checkedChangeListener);
adapter.addHeaderView(treeHeaderView);
initNode();
// Refresh the entire list
adapter.notifyDataSetChanged();
}
This function is implemented. After clicking to add a node, the interface is refreshed. Interested partners are welcome to study together.
