Android 下拉刷新

以前旧版用的是开源的PullToRefresh第三方库，该库现在已经不再维护了：

在support v4中google提供了SwipeRefreshLayout 来实现下拉刷新

说明： 在support v4兼容包下，但必须把你的support library的版本升级到19.1

Demo:

setOnRefreshListener(OnRefreshListener): 为布局添加一个Listener
setRefreshing(boolean): 显示或隐藏刷新进度条
isRefreshing(): 检查是否处于刷新状态
setColorScheme(): 设置进度条的颜色主题，最多能设置四种


protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    swipeLayout = (SwipeRfreshLayout) findViewById(R.id.swipe_container);
    swipeLayout.setOnRefreshListener(this);
    swipeLayout.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);
}

public void onRefresh() {
    new Handler().postDelayed(new Runnable()) {
        @Override
        public void run() {
            swipeLayout.setRefreshing(false);
        }
    }, 5000);
}

 PS：setColorScheme()已经弃用，使用setColorSchemeResources()来设置颜色。
