Android下拉/上拉刷新ListView之Android-PullToRefresh

Android下拉和上拉刷新ListView列表内容的的一个优秀开源框架，在github上的项目链接地址：https://github.com/chrisbanes/Android-PullToRefresh

该PullToRefresh第三方控件功能强大，使用方便。
具体使用方法：

（1）首先到github上把该项目下载解压，导入到Eclipse的工程中。
（2）将Android-PullToRefresh作为一个lib引用到自己的项目中。
然后直接使用即可。
现在给出一个Demo。

    private PullToRefreshListView mPullRefreshListView;
    private LinkedList<String> mListItems;
    private ArrayAdapter<String> mAdapter;
    // 数据
    private int DATA = 0;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        mPullRefreshListView = (PullToRefreshListView) findViewById(R.id.pull_refresh_list);
        // Mode.BOTH：支持下拉和上拉刷新。
        mPullRefreshListView.setMode(Mode.BOTH);
        mPullRefreshListView
                .setOnRefreshListener(new OnRefreshListener2<ListView>() {
                    // 下拉
                    @Override
                    public void onPullDownToRefresh(
                            PullToRefreshBase<ListView> refreshView) {
                        Toast.makeText(getApplicationContext(), "下拉刷新",
                                Toast.LENGTH_SHORT).show();
                        addItem();
                    }
                    // 上拉
                    @Override
                    public void onPullUpToRefresh(
                            PullToRefreshBase<ListView> refreshView) {
                        Toast.makeText(getApplicationContext(), "上拉刷新",
                                Toast.LENGTH_SHORT).show();
                        addItem();
                    }
                });
        // 列表到底，即看到最后一个元素。
        mPullRefreshListView
                .setOnLastItemVisibleListener(new OnLastItemVisibleListener() {
                    @Override
                    public void onLastItemVisible() {
                        Toast.makeText(getApplication(), "已经到底！",
                                Toast.LENGTH_SHORT).show();
                    }
                });
        ListView actualListView = mPullRefreshListView.getRefreshableView();
        mListItems = new LinkedList<String>();
        mAdapter = new ArrayAdapter<String>(this,
                android.R.layout.simple_list_item_1, mListItems);
        actualListView.setAdapter(mAdapter);
    }
    // 添加数据
    private void addItem() {
        new Handler().postDelayed(new Runnable() {
            @Override
            public void run() {
                mListItems.add((DATA++) + "");
                mAdapter.notifyDataSetChanged();
                mPullRefreshListView.onRefreshComplete();
            }
        }, 1000);
    }
}

需要的activity_main.xml

    android:layout_width="match_parent"
    android:layout_height="match_parent" >
    <com.handmark.pulltorefresh.library.PullToRefreshListView
