Implementing the "pull to refresh" feature in Android 5.1 upwards is fairly straightforward. Here are the steps:
1. Wrap the list where you want to implement it with a SwipeRefreshLayout
2. Get the SwipeRefreshLayout in the Activity or Fragment in onCreateView method like so
3. If using a Fragment, add a method onViewCreated. In it attach the onRefreshListener to the SwipeRefreshLayout
Done.
1. Wrap the list where you want to implement it with a SwipeRefreshLayout
<android.support.v4.widget.SwipeRefreshLayout xmlns:android="http://schemas.android.com/apk/res/android" android:id="@+id/swiperefresh" android:layout_width="match_parent" android:layout_height="match_parent"> <ListView android:id="@android:id/list" android:layout_width="match_parent" android:layout_height="match_parent" /> </android.support.v4.widget.SwipeRefreshLayout>
swipeRefreshLayout = (SwipeRefreshLayout) view.findViewById(R.id.swiperefresh);
3. If using a Fragment, add a method onViewCreated. In it attach the onRefreshListener to the SwipeRefreshLayout
@Override
public void onViewCreated(View view, Bundle savedInstanceState)
{
super.onViewCreated(view, savedInstanceState);
swipeRefreshLayout.setOnRefreshListener(new SwipeRefreshLayout.OnRefreshListener() {
@Override
public void onRefresh() {
Log.i(TAG, "onRefresh called from SwipeRefreshLayout");
//add code here to refresh the list
}
});
}
Done.
