ListView滑动刷新之SwipeRefreshLayout

SwipeRefreshLayout组件只接受一个子组件：即需要刷新的那个组件。

如果要展示一个“刷新动画”，它必须调用setRefrshing（true），否则取消动画就调用setRefreshing（false）。

@Override

protected void onCreate(Bundle savedInstanceState) {

    super.onCreate(savedInstanceState);

    setContentView(R.layout.activity_main);

    final SwipeRefreshLayout swipeView = (SwipeRefreshLayout) findViewById(R.id.swipe);

    final TextView rndNum = (TextView) findViewById(R.id.rndNum);

    swipeView.setColorScheme(android.R.color.holo_blue_dark, android.R.color.holo_blue_light, android.R.color.holo_green_light, android.R.color.holo_green_light);

    swipeView.setOnRefreshListener(new SwipeRefreshLayout.OnRefreshListener() {

        @Override

        public void onRefresh() {

            swipeView.setRefreshing(true);

            Log.d("Swipe", "Refreshing Number");

            ( new Handler()).postDelayed(new Runnable() {

                @Override

                public void run() {

                    swipeView.setRefreshing(false);

                    double f = Math.random();

                    rndNum.setText(String.valueOf(f));

                }

            }, 3000);

        }

    });

}
