使用 RecyclerView 轻扫以刷新

要使用 RecyclerView 添加“ 滑动以刷新” 布局，请将以下内容添加到“活动/片段”布局文件中： ****

<android.support.v4.widget.SwipeRefreshLayout
    android:id="@+id/refresh_layout"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    app:layout_behavior="@string/appbar_scrolling_view_behavior">

    <android.support.v7.widget.RecyclerView
        android:id="@+id/recycler_view"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:orientation="vertical"
        android:scrollbars="vertical" />

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

在你的 Activity / Fragment 中添加以下内容以初始化 SwipeToRefreshLayout ：

    SwipeRefreshLayout mSwipeRefreshLayout = (SwipeRefreshLayout) findViewById(R.id.refresh_layout);
    mSwipeRefreshLayout.setColorSchemeResources(R.color.green_bg,
            android.R.color.holo_green_light,
            android.R.color.holo_orange_light,
            android.R.color.holo_red_light);

    mSwipeRefreshLayout.setOnRefreshListener(new SwipeRefreshLayout.OnRefreshListener() {
        @Override
        public void onRefresh() {
            // Execute code when refresh layout swiped
        }
    });
