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" />  

设置Mode ```javaPullToRefreshListView 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 DownMode.PULL_FROM_END：只支持上拉Pulling Up3. 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：```javapublic 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();          }      }  }
