SwipeRefreshLayout与ViewPager

Question

我正在尝试在我的应用程序上实现刷刷新，但是由于我刚开始使用java，我有点不知道该把什么放在哪里。

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

        <androidx.viewpager.widget.ViewPager
            android:id="@+id/viewpager_fragments"
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            android:layout_above="@id/ad_banner_container"
            android:layout_below="@id/tabs">

        </androidx.viewpager.widget.ViewPager>

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

所以您可以看到我的xlm代码用于刷刷新，这里也是我的主要活动代码，可以告诉我在这里放什么吗？

mySwipeRefreshLayout.setOnRefreshListener(
                new SwipeRefreshLayout.OnRefreshListener() {
                    @Override
                    public void onRefresh() {
                        Log.i(LOG_TAG, "onRefresh called from SwipeRefreshLayout");

                        // This method performs the actual data-refresh operation.
                        // The method calls setRefreshing(false) when it's finished.
                        myUpdateOperation();
                    }
                }
        );

    mySwipeRefreshLayout.setOnRefreshListener(
                    new SwipeRefreshLayout.OnRefreshListener() {
                        @Override
                        public void onRefresh() {
                    Log.i(LOG_TAG, "onRefresh called from SwipeRefreshLayout");
                    shuffle(); // the function that populates your view 
                    mSwipeRefreshLayout.setRefreshing(false);
                            myUpdateOperation();
                        }
                    }
            );

洗牌可以是一种功能，如

public void shuffle(){
        Collections.shuffle(arrayList, new Random(System.currentTimeMillis()));
        ArrayAdapter adapter = new ArrayAdapter(this, android.R.layout.simple_list_item_1, arrayList);
        mListView.setAdapter(adapter);
    }
