pulltorefresh上拉加载以及下拉刷新

这里我是封装了一个上下拉的library，单纯的看的话不太懂，可以直接下载了自己去了解一下

然后就是recyclerview的点击和长按监听，我是在适配器中做了个接口，然后通过接口回调实现的：

首先要导入pulltorefresh的library

然后是main.xml布局

    android:layout_width="match_parent"
    android:layout_height="match_parent">

    //调用pulltorefreshi中的listview

            android:id="@+id/listview"
        android:layout_width="match_parent"
        android:layout_height="match_parent"/>  

在mainactivity中

 @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        listview= (PullToRefreshListView) findViewById(R.id.listview);

        // 设置pullToRefreshListView的刷新模式，BOTH代表支持上拉和下拉，PULL_FROM_END代表上拉,PULL_FROM_START代表下拉 */
        listview.setMode(PullToRefreshBase.Mode.BOTH);

        // 上下拉的监听
        listview.setOnRefreshListener(this);
        getXml();
    }

   //这是网络请求

   public void getXml() {
        new Thread(){
            @Override
            public void run() {
                super.run();
                try {
                    URL url=new URL("http://www.oschina.net/action/api/news_list?catalog=1&pageIndex=\"+ye+\"&pageSize=20");
                    HttpURLConnection urlConnection= (HttpURLConnection) url.openConnection();
                    urlConnection.setRequestMethod("GET");
                    int code=urlConnection.getResponseCode();
                    if (code==200) {
                        InputStream inputStream=urlConnection.getInputStream();
                        jieXml(inputStream);

                        //发送到handler进行解析（我这里就不写了）

                        handler.sendEmptyMessage(0);

                    }
                } catch (MalformedURLException e) {
                    e.printStackTrace();
                } catch (IOException e) {
                    e.printStackTrace();
                }
            }
        }.start();
    }

这个是下拉刷新

@Override
    public void onPullDownToRefresh(PullToRefreshBase refreshView) {
        new Handler().postDelayed(new Runnable() {
            @Override
            public void run() {
                ye=1;
                list.clear();
                getXml();
            }
        },1000);
        myadapter.notifyDataSetChanged();
        new FinishRefreshed().execute();
    }

这个是上拉加载

    @Override
    public void onPullUpToRefresh(PullToRefreshBase refreshView) {
        new Handler().postDelayed(new Runnable() {
            @Override
            public void run() {
                ye++;
                getXml();
            }
        },1000);
        new FinishRefreshed().execute();
    }

内部类，写了上拉和下拉的时间

    private class FinishRefreshed extends AsyncTask{
        @Override
        protected Void doInBackground(Void... params) {
            try {

               //两秒
                Thread.sleep(2000);
            } catch (InterruptedException e) {
                e.printStackTrace();
            }
            return null;
        }

        @Override
        protected void onPostExecute(Void aVoid) {

            //刷新listview
            listview.onRefreshComplete();
        }
    }
}
