1. 设置Listview
layout文件中定义PullToRefreshListView
Xml代码
-
<com.jackie.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);
-
-
-
mListItems = new ArrayList<String>();
-
for (int i = 1; i <= 10; i++) {
-
mListItems.add("Item " + Integer.toString(i));
-
}
-
-
-
mListView = (PullToRefreshListView) findViewById(R.id.list_view);
-
mAdapter = new SampleListAdapter();
-
mListView.setAdapter(mAdapter);
-
-
-
mListView.setMode(Mode.BOTH);
-
mListView.setOnRefreshListener(new OnRefreshListener2<ListView>(){
-
-
-
@Override
-
public void onPullDownToRefresh(PullToRefreshBase<ListView> refreshView) {
-
-
mListItems = new ArrayList<String>();
-
for (int i = 1; i <= 10; i++) {
-
mListItems.add("Item " + Integer.toString(i));
-
}
-
mAdapter.notifyDataSetChanged();
-
-
new FinishRefresh().execute();
-
}
-
-
-
@Override
-
public void onPullUpToRefresh(PullToRefreshBase<ListView> refreshView) {
-
-
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();
-
}
-
}
-
}
