SwipeRefreshLayout trigger programmatically

Is there any way to trigger the SwipeRefreshLayout programmatically? The animation should start and the onRefresh method from the OnRefreshListener interface should get called.

Solution

  • if you are using the new swipeRefreshLayout intoduced in 5.0 enter image description here

    As the image shown above you just need to add the following line to trigger the swipe refresh layout programmatically

    Work

    in Java:

     mSwipeRefreshLayout.post(new Runnable() {
     @Override
     public void run() {
         mSwipeRefreshLayout.setRefreshing(true);
     }
 });

    on in Kotlin:

    mSwipeRefreshLayout.post { mSwipeRefreshLayout.isRefreshing = true }

    NOT work

    if you simply call in Java:

     mSwipeRefreshLayout.setRefreshing(true);

    or in Kotlin

     mSwipeRefreshLayout.isRefreshing = true

    it won't trigger the circle to animate, so by adding the above line u just make a delay in the UI thread so that it shows the circle animation inside the ui thread.

    By calling mSwipeRefreshLayout.setRefreshing(true) the OnRefreshListener will NOT get executed

    In order to stop the circular loading animation call mSwipeRefreshLayout.setRefreshing(false)
