Android下拉刷新-SwipeRefreshLayout,RecyclerView完全解析之下拉刷新与上拉加载SwipeRefreshLayout)

 SwipeRefrshLayout是Google官方更新的一个Widget,可以实现下拉刷新的效果。该控件集成自ViewGroup在support-v4兼容包下，不过我们需要升级supportlibrary的版本到19.1以上。基本使用的方法如下:

• setOnRefreshListener(OnRefreshListener):添加下拉刷新监听器
• setRefreshing(boolean):显示或者隐藏刷新进度条
• isRefreshing():检查是否处于刷新状态

• setColorSchemeResources():设置进度条的颜色主题，最多设置四种，以前的setColorScheme()方法已经弃用了。

• 先来看下简单的布局,在最外层加上SwipeRefreshLayout，但是子的View需要时可滚动的（ScrollView或ListView）

• <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
      xmlns:tools="http://schemas.android.com/tools" android:layout_width="match_parent"
      android:layout_height="match_parent"
      android:paddingLeft="@dimen/activity_horizontal_margin"
      android:paddingRight="@dimen/activity_horizontal_margin"
      android:paddingTop="@dimen/activity_vertical_margin"
      android:paddingBottom="@dimen/activity_vertical_margin" tools:context=".MainActivity">
   
      <android.support.v4.widget.SwipeRefreshLayout
          android:id="@+id/swipeRefreshLayout"
          android:layout_width="wrap_content"
          android:layout_height="wrap_content"
          >
          <ListView
              android:id="@+id/listView"
              android:layout_width="match_parent"
              android:layout_height="wrap_content">
   
           </ListView>
      </android.support.v4.widget.SwipeRefreshLayout>
   
   
  </RelativeLayout>

  MainActivity中onCreate中的初始化一下SwipeLayOut，需要注意的方法是setColorScheme()， 设置进度条的颜色主题，最多能设置四种；

  myListView = (ListView) findViewById(R.id.listView);
        mySwipeRefreshLayout = (SwipeRefreshLayout) findViewById(R.id.swipeRefreshLayout);
   
        mySwipeRefreshLayout.setOnRefreshListener(this);
        mySwipeRefreshLayout.setColorScheme(android.R.color.holo_blue_bright, android.R.color.holo_green_light,
                android.R.color.holo_orange_light, android.R.color.holo_red_light);
        listAdapter = new ArrayAdapter(this,android.R.layout.simple_list_item_1,listIDE);
        myListView.setAdapter(listAdapter);

  MainActivity中需要实现一下 SwipeRefreshLayout.OnRefreshListener 

• @Override
    public void onRefresh() {
   
        refreshHandler.sendEmptyMessageDelayed(REFRESH_STATUS, 1500);
    }

  最后初始化一下数据setRefreshing(boolean):，显示或隐藏刷新进度条

• private static final int REFRESH_STATUS =0;
    private ListView myListView;
    private SwipeRefreshLayout mySwipeRefreshLayout;
    private ArrayAdapter<String> listAdapter;
    private List<String> listIDE = new ArrayList<String>(Arrays.asList("Visual Studio", "Android Studio", "Eclipse", "Xcode"));
    private Handler refreshHandler = new Handler()
    {
        public void handleMessage(android.os.Message msg)
        {
            switch (msg.what)
            {
                case REFRESH_STATUS:
                    listIDE.removeAll(listIDE);
                    listIDE.addAll(Arrays.asList("C#", "Java", "C++","Object-C"));
                    listAdapter.notifyDataSetChanged();
                    mySwipeRefreshLayout.setRefreshing(false);
                    break;
   
            }
        };
    };
