How to create a custom ListView in Sketchware?

The recently added Custom View in Sketchware can be used to create custom ListView. The steps you need to follow in order to create a custom ListView are given below.


1. In VIEW area of your sketchware project, add a ListView.

2. Add a new CustomView.

3. Now in properties of ListView, select the new view you added as customView.

4. Now in the VIEW area of CustomView, add a Linear (H) and a TextView.

5. In LOGIC area of your app, add a new list Map.

6. In onCreate event in your project, add items to the Map list using a single key. After adding items to list, setListCustomViewData of ListView to List Map (See image below).

7. In LOGIC area of your app add a new event​ ListView: onBindCustomView.

8. In event ListView: onBindCustomView, set the text of TextView in CustomView to the data from list Map.

9. If you want to implement some action on clicking any particular item in CustomView​, use the When view... clicked block available at the place where new variables are added.


10. Save and run the project to see the Custom ListView.

The video below shows how multiple lists can be used in a single Custom ListView.

      You need to add BackgroundService or BroadcastReceiver. It cannot be done in Sketchware. Maybe be possible in modded Sketchware, I'm not sure.

      Check these:
