사용예시

public class MainActivity extends AppCompatActivity {

    private static final String TAG = "MainActivity";
    private SwipeRefreshLayout swipeRefreshLayout;
    private ListView listView;
    private List<Integer> items;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        swipeRefreshLayout = findViewById(R.id.swipe_refresh);
        listView = findViewById(R.id.list_view);
        items = new ArrayList<>();

        //초기값 설정
        items.add(10);
        items.add(20);
        items.add(30);
        items.add(40);
        items.add(50);
        items.add(60);
        items.add(70);

        final ArrayAdapter<Integer> adapter = new ArrayAdapter<>(MainActivity.this, android.R.layout.simple_list_item_1, items);
        listView.setAdapter(adapter);

        swipeRefreshLayout.setColorSchemeResources(android.R.color.holo_red_dark);
        swipeRefreshLayout.setOnRefreshListener(new SwipeRefreshLayout.OnRefreshListener() {
            @Override
            public void onRefresh() {
                insertData();
                adapter.notifyDataSetChanged();
                swipeRefreshLayout.setRefreshing(false);
            }
        });
    }

    public void insertData(){
        Random r = new Random();
        int ranNum = r.nextInt(100)+1;
        items.add(ranNum);
        Collections.sort(items);
    }
}

실제 적용

xml

<androidx.swiperefreshlayout.widget.SwipeRefreshLayout
        android:id="@+id/swipeLy"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_marginStart="20dp"
        android:layout_marginEnd="20dp"
        android:layout_marginTop="10dp">

        <androidx.recyclerview.widget.RecyclerView
            android:id="@+id/rvPosts"
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            android:orientation="vertical" />

    </androidx.swiperefreshlayout.widget.SwipeRefreshLayout>

java

@Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container,
                             Bundle savedInstanceState) {
        View view = inflater.inflate(R.layout.fragment_home, container, false);
        Log.d(TAG, "onCreateView: context " + getContext());

        swipeRefreshLayout = view.findViewById(R.id.swipeLy);

        rvKeywords = (RecyclerView) view.findViewById(R.id.rvKeywords);
        rvPosts = (RecyclerView) view.findViewById(R.id.rvPosts);

        initAdapter();
        initSetting();
        initData();

        return view;
    }

@Override
    public void initSetting() {
        swipeRefreshLayout.setColorSchemeResources(R.color.green);
        swipeRefreshLayout.setOnRefreshListener(new SwipeRefreshLayout.OnRefreshListener() {
            @Override
            public void onRefresh() {
                Log.d(TAG, "onRefresh: ");
                initData();
                swipeRefreshLayout.setRefreshing(false);
            }
        });
    

데이터 초기화를 onCreate 에서 하고 스와이프 쓰면 일케 됨
