What is TreeView and How it looks?

TreeView is a pattern for the representation of data in the form of a tree so that it becomes easier for users to understand the organization of data in our app. A sample image is given below to get an idea of what TreeView looks like.

If you are looking for new UI designs to represent huge data, then there are so many ways to represent this type of data. You can use pie charts, graphs, and many more view types to implement these views. For displaying such huge data then we can prefer using a TreeView. TreeView is similar to that of a tree in which it has a parent node and inside that parent node, you can create multiple nodes according to requirement. In this example, we can take a look at creating a TreeView in your Android application. Now we will move towards the implementation of Tree View. We are going to implement this project using both Java and Kotlin Programming Language for Android.
