Android Filtering

My app’s URL:

When you launch the app (or any Glide app I guess) on Android Smartphone and try to filter in-line lists, the native Android environment does not feature a “check” or “confirm” button to confirm your choice of filtering, which means that the user gets confused. Eventually, the users will find out they need to tap the “back” button to confirm their choice of filtering.

Is there a workaround, please?
