Sometime we need to refresh our list when we swipe down at top of our list so this feature is attained with the help of Swipe Refresh Layout. Here I am showing the list with the help of recyclerView, so we need to add SwipeRefreshLayout tag in our xml file, below is the code.

my_layout.xml

<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools" android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:background="#DFEEED"
    tools:context="com.android.Fragment.Myfrag">
    <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:orientation="vertical">
     

    <android.support.v4.widget.SwipeRefreshLayout
        android:id="@+id/swipe_refresh_layout"
        android:layout_width="match_parent"
        android:layout_height="match_parent">
    <android.support.v7.widget.RecyclerView

        android:layout_marginTop="@dimen/margin50"
        android:id="@+id/nudge_recyclerview"
        android:layout_height="match_parent"
        android:layout_width="match_parent"
        android:layout_marginLeft="@dimen/margin10"
        android:layout_marginRight="@dimen/margin10"/>

    </android.support.v4.widget.SwipeRefreshLayout>
    </LinearLayout>
</FrameLayout>

Now below is the code for the activity where I have implemented recyclerView with SwipeRefreshLayout and its functionality, so here I have called the api from where I am getting the data that is to be fetched in recyclerView within the swiperefreshlayout.setOnRefreshListener.

MyActivity.java

public class YourNudges extends Fragment implements NudgeRecyclerViewAdapter.OnClickListener, MyPagerAdapter.Updateable {
    
    private RecyclerView mNudgesRView;
    private RecyclerView.Adapter mAdapter;
    private LinearLayoutManager mLayoutManager;
    private SwipeRefreshLayout swipeRefreshLayout;
    private Handler mHandler;
    

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

    }

    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container,
                             Bundle savedInstanceState) {
        // Inflate the layout for this fragment
        View view = inflater.inflate(R.layout.fragment_your_nudges, container, false);
        swipeRefreshLayout = (SwipeRefreshLayout) view.findViewById(R.id.swipe_refresh_layout);


// BELOW LINE MAKES THE LIST REFRESH WHEN YOU SWIPE AT TOP


        swipeRefreshLayout.setOnRefreshListener(new SwipeRefreshLayout.OnRefreshListener() {
            @Override
            public void onRefresh() {
                
                    getTheMessageAPI();     
            }
        });
            getTheMessageAPI();
            return view;
    }

 
    public void getTheMessageAPI() {
       //Fetch your data in recyclerview over here
    }

    private void setRecyclerAdapter() {

// set your recyclerView Adapter over here
        
    }
  
}
