Graphical binary tree in Android

Question

I'm relatively new to Android and stuck with this problem. I need to create a UI with a graphical binary tree. Tree nodes contain some text and a small image. I went through the Android developer guide, but couldn't find a way to do this.

Is it possible to draw a binary tree in Android? If it is, what controls should I use? If possible please tell me where I can find more information as well.

did you able to find any solution. I am stuck in such kind of problem — Farhana Haque, Dec 15 '15 at 05:57

I think implementing the onDraw is your best bet here since you need a lot of customization and there is no default component for it. Please refer to the documentation on how to do it.

Here is a library which implements binary tree so you can check out how they are drawing it.

Hope it helps!

I think you should subclass the View class and implement onDraw(Canvas) method http://developer.android.com/guide/topics/ui/custom-components.html

Use "de.blox.treeview:treeview:0.1.0" library. You can find how to do it on Geeks For Geeks.
