Our MainActivity shall derive from AppCompatActivity while we shall also use Floating action button from design support libraries.

Also Add dependencies for AppCompat and Design support libraries.

The app level belongs inside the app folder and its where we normally add our dependencies and specify the compile and target sdks. One is the app level adle, the other is project level adle.

Normally in android projects, there are two adle files.Add the dependency for draggabletreeview as shown below. NOTE: Do not place your application dependencies here they belong Top-level build file where you can add configuration options common to all sub-projects/modules.Ĭlasspath ':gradle:2.3.3' We specify the repository where our draggabletreeview library will be fetched from, in this jitpack.io.We use Android DraggableTreeView library by Jake Bonk.Topic : DraggableTreeView, TreeView Adapter, Drag Drop treenodes Libaries Used.This example was written with the following tools: Android SimpleTreeview adapter Tools Used.Android Drag tree tutorial and example.Android nesting views with draggabletreeview.

How to drag and drop item views in a treeview in android.

Android TreeView example tutorial java.

You can find more details about the library here. We use a DraggableTreeView library by Jake Bonk. We this set adapter to our draggabletreeview.

We instantiate it passing in the context as well as our root treenode. This is an adapterview, so we have SimpleTreeViewAdapter class.

#Android treeview code#

Of course we can do this programmatically in code or at runtime.

We can nest the items by adding them as children to specific treenodes. We then instantiate as many treenodes as we like. It’s quite easy to use, once we’ve added dragtreeview component in our xml layout, we then reference it inside our mainactivity. The nodes in the tree can then be dragged and nested infinitely. This is a custom adapter view that can render items in a tree manner. This is an android draggabletreeview tutorial. Example 1: Android DraggableTreeView – Drag and Nest TreeNodes TreeView isn’t built into the android sdk but developers have created a few libraries that allow us implement a treeview with most of the features that you would expect in such a widget. In this piece we want to look at TreeView examples in android.
