Drag and Drop in Expandable Listview

I am working on Expandable ListView and now I want to perform drag and drop in Expandable ListView. It was too hard to perform drag and drop on Expandable listview. not a single library I got on it and not a single working code snippet I got which is working .

Then I came to know about this git. This is Expandable ListView with Drag and Drop functionality. But this is not neat. I mean it can not move Items up and down when we are dragging our Item. I achieved similar things on iOS very easily. but In android I did not find any kind of help.

I am not sure if android user did not like expandable listview like pattern. but I know this is usual thing but I am helpless now. Please help me
