无限滚动列表视图不起作用 [英] Endless scrolling listview not working

问题描述

我正在开发一个应用程序.在我的应用程序中，我使用 listview 来显示来自 json 的数据.所有数据显示完美.但我想要的是，显示前 10 个对象，然后加载项目应该显示，然后剩余的 10 个将显示.我的 json 响应如下所示.

解决方案

要在 ListView 中第一次仅显示 10 个项目并在滚动时显示更多项目，请执行以下步骤:

步骤 1: 创建一个 chunkList 方法，将 ArrayList 分成大小为 10 的部分:

static List>chunkList(List list, final int L) {List>部分 = 新的 ArrayList>();最终 int N = list.size();for (int i = 0; i (list.subList(i, Math.min(N, i + L))));}退回零件；}

第 2 步: 创建 ArrayList 和一个显示当前部分的计数器:

 private boolean isLoadingMore=false;Handler mHandler = new Handler();List>主数组列表；私有整数计数=0；

步骤 3: 在 onPostExecute 中打破 result 并在 ListView 中显示数据:

protected void onPostExecute(ArrayList> result) {super.onPostExecute(result);//你的代码在这里...mainArrayList=chunkList(result,10);isLoadingMore=false;计数=0；适配器 = 新 CustomAdapterSent(Interestsent.this,mainArrayList.get(count));setListAdapter(适配器)；}}

第 4 步: 在 Adapter 中创建 addAll 方法以在当前数据源中附加数据:

public void addAll(ArrayList>moreData){this.listData.addAll(moreData);this.notifyDataSetChanged();}

步骤 5: 在 onLoadMore 中加载更多数据到 ListView:

mHandler = new Handler();listview.setOnScrollListener(new EndlessScrollListener() {@覆盖public void onLoadMore(int page, int totalItemsCount) {if(count

I am developing one application. In my app I am using listview to display data from json. All the data display perfectly. But what I want is, to display first 10 objects and then loading items should show and then remaining 10 will display. My json response is as given below.

解决方案

To Show only 10 item first time in ListView and show more items on scroll follow following steps:

STEP 1: Create a chunkList method which divide ArrayList in parts of size 10:

static <T> List<ArrayList<T>> chunkList(List<T> list, final int L) {
        List<ArrayList<T>> parts = new ArrayList<ArrayList<T>>();
        final int N = list.size();
        for (int i = 0; i < N; i += L) {
            parts.add(new ArrayList<T>(
                list.subList(i, Math.min(N, i + L)))
            );
        }
        return parts;
    }

STEP 2: Create ArrayList and a counter which show current part :

    private boolean isLoadingMore=false;
    Handler mHandler = new Handler();
    List<ArrayList<HashMap<String,String>>> mainArrayList;
    private int count=0;

STEP 3: In onPostExecute break result and show data in ListView:

protected void onPostExecute(ArrayList<HashMap<String,String>> result) {

              super.onPostExecute(result);
              // your code here...
               mainArrayList=chunkList(result,10);
               isLoadingMore=false;
               count=0;
               adapter = new CustomAdapterSent(Interestsent.this, 
                                            mainArrayList.get(count));
               setListAdapter(adapter);
        }

    }

STEP 4: Create addAll method in Adapter to append data in current data source :

public void addAll(ArrayList<HashMap<String,String>> moreData){
   this.listData.addAll(moreData);
   this.notifyDataSetChanged();
}

STEP 5: In onLoadMore load more data in ListView:

mHandler = new Handler();
 listview.setOnScrollListener(new EndlessScrollListener() {
        @Override
        public void onLoadMore(int page, int totalItemsCount) {
                 if(count<mainArrayList.size()-1)
                  {
                     if(adapter !=null){
            count++;                       
            if(!isLoadingMore){
                             isLoadingMore=true;
                             mHandler.postDelayed(loadMoreRunnable,1000); 
                          } 
                      }
                  } 
        }
        });
    }

     Runnable loadMoreRunnable = new Runnable() {

        @Override
        public void run() {
            // TODO Auto-generated method stub
         if(count<mainArrayList.size())
                   {
                     if(adapter !=null){
                      count++;                       
                      adapter.addAll(mainArrayList.get(count));
                      mHandler.removeCallbacks(loadMoreRunnable);
                      isLoadingMore=false;
                      }
                  } 
        }
    };
