Android Question How Stop Downloading on CustomListview?

Ertan · Jan 13, 2021

Hello there,
I am using CustomListView.
I am printing pictures and a few articles in the CustomListView.
I print these contents by parsing the JSON data.

I have such a problem.
When I add the data sequentially with customlistview and its addition is not completed yet, if the user finishes the activity, the activity is automatically opened again and customlistview is loaded again.

I want to do that.

If the user does activity finish, I want to cancel the download process.

I am using translation. If not understood, I can shoot a video. I can add a sample project.

Thank you so much.

Better do that.

As a suggested solution :

you can define a public variable lDownload = true;
and make it false when activity finish
and check this variable before next download.

Regards,

Anand

I'll try it tomorrow when I go to the office. If I fail, I'll write it. Thank you.

I put a 250 millisecond wait to show what happened.

Step 1- Immediately after the data is listed, exit with the Back button.
The activity will restart automatically.
Am I taking a missing step somewhere?
How can I prevent this? I do not have this problem on iOS.

Thank you.

Stop wasting your time with activities and switch to B4XPages. Especially if you are building cross platform solutions.

All these challenges will simply disappear.

If you insist on using activities then move the communication code to a service.

Thank you. The project I experienced this event is a big project. That's why I don't think I can get through.
I will use B4XPages in my new projects.

This solution came to mind, but I wanted to ask if there might be a solution to stop downloading.

Thank you.

You can use RequestsManager class to cancel ongoing requests: https://github.com/AnywhereSoftware/B4X-Pleroma/blob/master/RequestsManager.bas
