• 使用Swiperefreshlayout

地址：https://developer.android.google.cn/jetpack/androidx/releases/swiperefreshlayout
依赖：implementation "androidx.swiperefreshlayout:swiperefreshlayout:1.0.0"
要下拉刷新的内容放：androidx.swiperefreshlayout.widget.SwipeRefreshLayout里
用法：

        swipeRefreshLayout = findViewById(R.id.layout_SwReFresh);
        swipeRefreshLayout.setOnRefreshListener(new SwipeRefreshLayout.OnRefreshListener() {
            @Override
            public void onRefresh() {
                loadImage(); // 下拉执行的操作
            }
        });
// 执行的操作里最后添加：
      if (swipeRefreshLayout.isRefreshing()){
             swipeRefreshLayout.setRefreshing(false);
