Android--下拉刷新

创建一个自定义方法
记得要初始化对象

    private void handlerDownPullUpdate(){
        refresh_main.setOnRefreshListener(new SwipeRefreshLayout.OnRefreshListener() {
            @Override
            public void onRefresh() {
                new Handler().postDelayed(new Thread(){
                    @Override
                    public void run() {
                        refresh_main.setRefreshing(false);
                    }
                }, 3000);

            }
        });
    }

布局

    <androidx.swiperefreshlayout.widget.SwipeRefreshLayout
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:id="@+id/refresh_main">

    </androidx.swiperefreshlayout.widget.SwipeRefreshLayout>
