You can create a table or any string array... with at least two columns...
id and childofid... if chiofid is null,"" is the root

You can make a canvas with scrollpane and draw all these easy or you can use layouts and scrollpane to be easier...

Interesting task, it's interesting if any code solution will be published here, when and if developed...

I think is simple as idea... may could be difficult in design if tree has many childs in a row...

The class described HERE made it easy and quick to create the demo below. Zip includes class.

Version 2 has specs for nodes and arrows, as well as touch sensitivity for both nodes and arrows. It is still less than 150 lines of code.

A number of years ago I created a couple of projects in B4A... one an interactive fiction creator for a school, the other for our site engineers for Wire and Network schematics... Its Similar to the previous post.
I created these in B4A, I've used a Canvas with Labels and drawn lines and the Pinch and Zoom Lib.
So the user can tap and hold on a node, then move it around keeping the connecting lines connected to the relevant nodes.
