android 下拉刷新listview,Android中常见的下拉刷新ListView

下拉刷新在越来越多的应用程序中使用，它已经形成了默认的用户习惯，当遇到列表中显示的内容时，用户开始习惯性地下拉，那么中常见的下拉刷新ListView有哪些呢？下面就让爱站技术频道小编带你一起进入下文了解一下吧！

在交互习惯上已经形成定性。之前在我的文章《IOS学习笔记34—EGOTableViewPullRefresh实现下拉刷新》中介绍过如何在IOS上实现下拉刷新的功能。今天主要介绍下在Android上实现下拉刷新的Demo，下拉控件参考自Github上开源项目PullToRefresh，并做简单修改。最终效果如下：

工程结构如下：

使用过程中可以对下拉显示效果进行自定义，如果要修改顶部下拉显示，则只需修改pulllist_head.xml即可，修改底部获取更多则修改list_footview.xml即可。

接下来是在Activity中使用：

/**

* PullListView

* @author Ryan

*

*/

public class RTPullListViewActivity extends Activity {

private static final int INTERNET_FAILURE = -1;

private static final int LOAD_SUCCESS = 1;

private static final int LOAD_MORE_SUCCESS = 3;

private static final int NO_MORE_INFO = 4;

private static final int LOAD_NEW_INFO = 5;

private RTPullListView pullListView;

private ProgressBar moreProgressBar;

private ListdataList;

private ArrayAdapteradapter;

@Override

public void onCreate(Bundle savedInstanceState) {

super.onCreate(savedInstanceState);

setContentView(R.layout.main);

pullListView = (RTPullListView) this.findViewById(R.id.pullListView);

dataList = new ArrayList();

for (int i = 0; i < 5; i++) {

dataList.add("Item data "+i);

}

adapter = new ArrayAdapter(this, android.R.layout.simple_list_item_1, dataList);

pullListView.setAdapter(adapter);

//添加listview底部获取更多按钮(可自定义)

LayoutInflater inflater = LayoutInflater.from(this);

View view = inflater.inflate(R.layout.list_footview, null);

RelativeLayout footerView =(RelativeLayout) view.findViewById(R.id.list_footview);

moreProgressBar = (ProgressBar) view.findViewById(R.id.footer_progress);

pullListView.addFooterView(footerView);

//下拉刷新监听器

pullListView.setonRefreshListener(new OnRefreshListener() {

@Override

public void onRefresh() {

new Thread(new Runnable() {

@Override

public void run() {

try {

//模拟数据刷新

Thread.sleep(2000);

dataList.clear();

for (int i = 0; i < 5; i++) {

dataList.add("Item data "+i);

}

myHandler.sendEmptyMessage(LOAD_NEW_INFO);

} catch (InterruptedException e) {

e.printStackTrace();

}

}

}).start();

}

});

//获取更多监听器

footerView.setOnClickListener(new OnClickListener() {

@Override

public void onClick(View v) {

moreProgressBar.setVisibility(View.VISIBLE);

new Thread(new Runnable() {

@Override

public void run() {

try {

//模拟数据刷新

Thread.sleep(2000);

for (int i = 0; i < 5; i++) {

dataList.add("New item data "+i);

}

myHandler.sendEmptyMessage(LOAD_MORE_SUCCESS);

} catch (InterruptedException e) {

e.printStackTrace();

}

}

}).start();

}

});

}

//结果处理

private Handler myHandler = new Handler(){

@Override

public void handleMessage(Message msg) {

super.handleMessage(msg);

switch (msg.what) {

case LOAD_MORE_SUCCESS:

moreProgressBar.setVisibility(View.GONE);

adapter.notifyDataSetChanged();

pullListView.setSelectionfoot();

break;

case LOAD_NEW_INFO:

adapter.notifyDataSetChanged();

pullListView.onRefreshComplete();

break;

default:

break;

}

}

};

}
