java - Android Treeview

Question

I know there is the ExpandableListView but it only supports up to 2 levels. I need a true treeview vertical list with at least up to ~5 levels (more is better).

Any suggestions?

edit:

I see talk about using a Custom Adapter and setting the padding based on the items level.

I have an unsorted ArrayList of objects that have an ID and parent ID, and I dynamically add items to this array as well.

Can anyone give me some examples of how I can go about doing this?

I had the same issue. You can check out my implementation AndroidTreeView.

• Its N-level tree.
  

• Custom style for nodes
  

• Save state after rotation
