1. 设置Listview 
layout文件中定义PullToRefreshListView 

Xml代码

<com.handmark.pulltorefresh.library.PullToRefreshListView  
    android:id="@+id/list_view"  
    android:layout_width="match_parent"  
    android:layout_height="match_parent" />  

2. 设置Mode 

PullToRefreshListView mListView = (PullToRefreshListView) findViewById(R.id.list_view);  
mListView.setMode(Mode.BOTH);  

可支持的Mode如下：

• Mode.BOTH：同时支持上拉下拉
• Mode.PULL_FROM_START：只支持下拉Pulling Down
• Mode.PULL_FROM_END：只支持上拉Pulling Up

3. 实现监听Listener
如果Mode设置成Mode.BOTH，需要设置监听OnRefreshListener2，并实现onPullDownToRefresh()、onPullUpToRefresh()两个方法。 

如果Mode设置成Mode.PULL_FROM_START或Mode.PULL_FROM_END，需要设置监听OnRefreshListener，同时实现onRefresh()方法。当然也可以设置为OnRefreshListener2，但是Mode.PULL_FROM_START的时候只调用onPullDownToRefresh()方法，Mode.PULL_FROM的时候只调用onPullUpToRefresh()方法。

4. 具体代码如下：

public class MainActivity extends Activity {  
      
    private ArrayList<String> mListItems;  
    private PullToRefreshListView mListView;  
    private SampleListAdapter mAdapter;  
      
    @Override  
    protected void onCreate(Bundle savedInstanceState) {  
        super.onCreate(savedInstanceState);  
        setContentView(R.layout.sample);  
          
        // 设置初期数据  
        mListItems = new ArrayList<String>();  
        for (int i = 1; i <= 10; i++) {  
            mListItems.add("Item " + Integer.toString(i));  
        }  
  
        // 设置ListView  
        mListView = (PullToRefreshListView) findViewById(R.id.list_view);  
        mAdapter = new SampleListAdapter();  
        mListView.setAdapter(mAdapter);  
          
        // 设置PullToRefresh  
        mListView.setMode(Mode.BOTH);  
        mListView.setOnRefreshListener(new OnRefreshListener2<ListView>(){  
   
            // 下拉Pulling Down  
            @Override  
            public void onPullDownToRefresh(PullToRefreshBase<ListView> refreshView) {  
                // 下拉的时候数据重置  
                mListItems = new ArrayList<String>();  
                for (int i = 1; i <= 10; i++) {  
                    mListItems.add("Item " + Integer.toString(i));  
                }  
                mAdapter.notifyDataSetChanged();  
                  
                new FinishRefresh().execute();  
            }  
              
            // 上拉Pulling Up  
            @Override  
            public void onPullUpToRefresh(PullToRefreshBase<ListView> refreshView) {  
                // 上拉的时候添加选项  
                int count = mListItems.size();  
                mListItems.add("Item " + Integer.toString(++count));  
                mAdapter.notifyDataSetChanged();  
                  
                new FinishRefresh().execute();  
            }  
   
        });  
          
    }  
      
    private class SampleListAdapter extends BaseAdapter {  
           
        @Override  
        public int getCount() {  
            return mListItems.size();  
        }  
   
        @Override  
        public Object getItem(int index) {  
            return mListItems.get(index);  
        }  
   
        @Override  
        public long getItemId(int index) {  
            return index;  
        }  
   
        @Override  
        public View getView(int index, View view, ViewGroup arg2) {  
            if(view == null){  
                LayoutInflater inflater = (LayoutInflater)getSystemService(Context.LAYOUT_INFLATER_SERVICE);  
                view = inflater.inflate(R.layout.list_item, null);  
            }  
            TextView textView = (TextView)view.findViewById(R.id.listItemText);  
            textView.setText(mListItems.get(index));  
            return view;  
        }  
    }  
   
    private class FinishRefresh extends AsyncTask<Void, Void, Void>{  
        @Override  
        protected Void doInBackground(Void... params) {  
            return null;  
        }  
   
        @Override  
        protected void onPostExecute(Void result){  
            mListView.onRefreshComplete();  
        }  
    }  
}
