ListView onScroll添加更多項目

Question

    private class getArticles extends AsyncTask<Void, Void, Void> {

    String url;

    getArticles(String paramUrl) {
        this.url = paramUrl;
    }


    @Override
    protected void onPreExecute() {
        super.onPreExecute();
        mProgressDialog = new ProgressDialog(App.this);
        mProgressDialog.setMessage("Učitavanje artikala...");
        mProgressDialog.setIndeterminate(false);
        mProgressDialog.setCancelable(false);
        mProgressDialog.show();
    }

    @Override
    protected Void doInBackground(Void... params) {

        arraylist = new ArrayList<>();

        try {

            Document document = Jsoup.connect(url).get();
            Elements els = document.select("ul.category3 > li");

            for (Element el : els) {

                HashMap<String, String> map = new HashMap<>();

                Elements slika = el.select("div.category3-image > a > img");
                Elements naslov = el.select("div.category3-text > a.main-headline");
                Element datum_noformat = el.select("div.category3-text > div.headlines-info > ul.headlines-info > li").first();
                Element datum = datum_noformat.html(datum_noformat.html().replaceAll("Posted ", ""));
                Elements desc = el.select("div.category3-text > p");
                Elements link = el.select("div.category3-text > a.main-headline");
                Element br_kom = el.select("div.category3-text > div.headlines-info > ul.headlines-info > li.comments-icon").first();

                map.put("naslov", naslov.text());
                map.put("datum", datum.text());
                map.put("desc", desc.text());
                map.put("ikona", slika.attr("src"));
                map.put("link", link.attr("abs:href"));
                map.put("brkom", br_kom.text());
                arraylist.add(map);


            }
        } catch (IOException e) {
            e.printStackTrace();
        }
        return null;
    }

    @Override
    protected void onPostExecute(Void result) {
        listview = (ListView) findViewById(R.id.listview);
        adapter = new ArtikliAdapter(App.this, arraylist);
        listview.setAdapter(adapter);
        mProgressDialog.dismiss();
    }

我搜索了很多onlistview滾動的代碼，但不知道如何實現它。 問題是，當我調用我的asynctask時，我有一個url參數，比如new getArticles("http://example.com").execute();

我想實現一個onscrolllistener，但它是這樣的，我的param通常設置為： http://www.example.com/category/categoryname/ ： http://www.example.com/category/categoryname/ ，所以第二頁就像http://www.example.com/category/categoryname/page/2/ ，第三個是http://www.example.com/category/categoryname/page/3/ ，依此類推。 每個頁面都有7個需要解析的項目。

我怎么能實現onscrolllistener，因為url param？

提前致謝。

Answer 1

基於此鏈接 ，我編寫了以下解決方案，以異步方式將元素（一次30個元素，即頁面大小= 30）添加到listview。

創建一個名為EndlessListView的類，如下所示：

public class EndlessListView extends ListView implements OnScrollListener {

private View footer;
private boolean isLoading;
private EndlessListener listener;// listner
private EndlessAdapter endlessAdapter;// adapter.

private int maxNoOfElement;

public EndlessListView(Context context, AttributeSet attrs, int defStyle) {
    super(context, attrs, defStyle);
    this.setOnScrollListener(this);
}

public EndlessListView(Context context, AttributeSet attrs) {
    super(context, attrs);
    this.setOnScrollListener(this);
}

public EndlessListView(Context context) {
    super(context);
    this.setOnScrollListener(this);
}

public void setListener(EndlessListener listener) {
    this.listener = listener;
}

@Override
public void onScroll(AbsListView view, int firstVisibleItem,
        int visibleItemCount, int totalItemCount) {

    if (getAdapter() == null)
        return;

    if (getAdapter().getCount() == 0 || getAdapter().getCount() <= 5)
        return;

    int l = visibleItemCount + firstVisibleItem;
    if (l >= totalItemCount && !isLoading) {
        // It is time to add new data. We call the listener
        Log.e("LOAD", "DATA");
        isLoading = true;
        listener.loadData();

    }
}

public void setMaxElemnt(int maxNoOfElement) {
    this.maxNoOfElement = maxNoOfElement;
}

@Override
public void onScrollStateChanged(AbsListView view, int scrollState) {
}

public void setLoadingView(int resId) {
    LayoutInflater inflater = (LayoutInflater) super.getContext()
            .getSystemService(Context.LAYOUT_INFLATER_SERVICE);
    footer = (View) inflater.inflate(resId, null);
    this.addFooterView(footer);
}

public void setAdapter(EndlessAdapter adapter) {
    super.setAdapter(adapter);
    this.endlessAdapter = adapter;

}

public void addNewData(List<Integer> data) {
    endlessAdapter.setData(data);
    endlessAdapter.notifyDataSetChanged();
    isLoading = false;
}

public static interface EndlessListener {
    public void loadData();

}

 }

在此之后我們必須為它創建適配器，稱為

EndlessAdapter

public class EndlessAdapter extends BaseAdapter {
private List<Integer> mIntegers;
private Context context;

public EndlessAdapter(Context context) {
    this.context = context;
}

public void setData(List<Integer> mIntegers) {
    this.mIntegers = mIntegers;
}

@Override
public int getCount() {
    if (mIntegers == null)
        return 0;
    return mIntegers.size();
}

@Override
public Integer getItem(int index) {

    if (mIntegers == null) {
        return null;
    } else {
        return mIntegers.get(index);
    }
}

@Override
public long getItemId(int arg0) {
    // TODO Auto-generated method stub
    return 0;
}

class ViewHolder {
    TextView textView;
}

@Override
public View getView(int index, View view, ViewGroup viewGroup) {
    ViewHolder holder;
    if (view == null) {
        holder = new ViewHolder();
        view = ((LayoutInflater) context
                .getSystemService(Context.LAYOUT_INFLATER_SERVICE))
                .inflate(R.layout.rows, viewGroup, false);
        holder.textView = (TextView) view.findViewById(R.id.mtext);
        view.setTag(holder);

    } else {
        holder = (ViewHolder) view.getTag();
    }
    holder.textView.setText(getItem(index) + "");
    return view;
}

   }

現在在xml的活動中我們可以使用EndlessListView（在com.example.stackoverflow包中），如下所示：

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent" >

<com.example.stackoverflow.EndlessListView
    android:id="@+id/endlessListView"
    android:layout_width="match_parent"
    android:layout_height="wrap_content" />

</RelativeLayout>

完成此步驟后，我們需要在MainActivity中進行以下更改

    public class MainActivity extends Activity implements EndlessListener {
private EndlessAdapter adapter;
private EndlessListView endlessListView;
private List<Integer> data;
private int gStartIndex = 30;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    endlessListView = (EndlessListView) findViewById(R.id.endlessListView);
    adapter = new EndlessAdapter(this);
    data = new ArrayList<Integer>();

    endlessListView.setLoadingView(R.layout.footer);
    // endlessListView.showFooter();
    endlessListView.setListener(this);
    endlessListView.setAdapter(adapter);
    gStartIndex = 0;
    fillData(gStartIndex);
}

private void fillData(int startIndex) {

    new AsyncLoadData().execute(startIndex);

}

@Override
public void loadData() {

    fillData(gStartIndex);

}

private class AsyncLoadData extends AsyncTask<Integer, Integer, Void> {

    @Override
    protected Void doInBackground(Integer... params) {
        int gendIndex = params[0] + 30;
        gStartIndex = gendIndex;
        /***
         * Here you could add your n/w code. To simulate the n/w comm. i am
         * adding elements to list and making it sleep for few sec.
         * */
        for (int i = params[0]; i < gendIndex; i++) {
            publishProgress(i);

        }
        try {
            Thread.sleep(3000);
        } catch (InterruptedException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }
        return null;
    }

    @Override
    protected void onProgressUpdate(Integer... values) {
        super.onProgressUpdate(values);
        data.add(values[0]);
    }

    @Override
    protected void onPostExecute(Void result) {
        endlessListView.addNewData(data);
    }
}

    }

Answer 2

我剛剛找到的這個自定義ScrollListView具有OnBottomReachedListener ，您可以從Activity或Fragment實現它，並在用戶點擊頁面底部時接收事件。 您還需要跟蹤當前頁面以及點擊底部以下載下一頁。 應將最新數據添加到現有ArrayList並應在適配器上調用notifyDataSetChanged() ，以便ListView可以呈現新數據。 您不必創建新適配器，只需更新數據源即ArrayList 。

如果您支持方向更改，則必須在onSaveInstanceState()保存當前頁碼，以便在重新創建Activity或Fragment ，它可以從正確的頁面繼續。 並且您必須保持ArrayList數據源安全的配置更改，因為您不想再次下載它。 我建議使用Fragment並將setRetainInstance()設置為true來保持ArrayList 。

這是我使用RetainFragment保持數據的自定義代碼：

/**
 * A simple non-UI Fragment that stores a single Object
 * and is retained over configuration changes.
 */
public class RetainFragment<E extends Object> extends Fragment {

    /** Object for retaining. */
    private E mObject;

    /**
     * Empty constructor as per the Fragment documentation
     */
    public RetainFragment() {}

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        // Make sure this Fragment is retained over a configuration change
        setRetainInstance(true);
    }

    /**
     * Store a single object in this Fragment.
     *
     * @param object The object to store
     */
    public void setObject(E object) {
        mObject = object;
    }

    /**
     * Get the stored object.
     *
     * @return The stored object
     */
    public E getObject() {
        return mObject;
    }
}

Activity中RetainFragment用法的示例：

FragmentManager fm = getFragmentManager();
mRetainFragment = (RetainFragment<ArrayList>) fm.findFragmentByTag(RETAIN_FRAG);
if (mRetainFragment == null) {
    mRetainFragment = new RetainFragment<>();
    mRetainFragment.setObject(new ArrayList());
    fm.beginTransaction().add(mRetainFragment, RETAIN_FRAG).commit();
}

ArrayList yourArrayList = mRetainFragment.getObject();
// Now your ArrayList is saved accrossed configuration changes

這里你想要拳頭添加onscrolllistner到listview

      boolean loading_flage = false;

                                    yourlistview.setOnScrollListener(new OnScrollListener() {

                                        @Override
                                        public void onScrollStateChanged(
                                                AbsListView view,
                                                int scrollState) {
                                            // TODO Auto-generated method stub

                                        }

                                        @Override
                                        public void onScroll(AbsListView view,
                                                int firstVisibleItem,
                                                int visibleItemCount,
                                                int totalItemCount) {

                                            final int lastItem = firstVisibleItem
                                                    + visibleItemCount;

                                            if ((lastItem == totalItemCount)
                                                    & loading_flage == false) {

//this to prevent the list to make more than one request in time
                                                loading_flage = true;
    //you can put the index for your next page here
                                                loadMore(int page);

                                            }

                                        }
                                    });

然后在加載頁面后加載更多設置加載為false並解析數據將其添加到您已經擁有的數據中

                      //notify the adapter
                     adapter.notifyDataSetChanged();
                      loading_flage = false;

Answer 4

您可以通過在listview上添加scrolllistener並檢查條件，如果列表最后一個可見項在ArrayList中是最后一個，然后使用遞增的頁碼調用asynctask並更新listview，意味着在listview上添加視圖並在從服務器獲取結果后刪除從列表視圖加載更多視圖，如下所示 - AndroidListViewLoadMoreActivity.java

public class AndroidListViewLoadMoreActivity extends Activity {

 ArrayList<Country> countryList;
 MyCustomAdapter dataAdapter = null;
 int page = 0;
 boolean loadingMore = false;
 View loadMoreView;

 @Override
 public void onCreate(Bundle savedInstanceState) {
  super.onCreate(savedInstanceState);
  setContentView(R.layout.main);

  ListView listView = (ListView) findViewById(R.id.listView1);

  loadMoreView = ((LayoutInflater)this
    .getSystemService(Context.LAYOUT_INFLATER_SERVICE))
    .inflate(R.layout.loadmore, null, false);
  listView.addFooterView(loadMoreView);

  //create an ArrayAdaptar from the String Array
  countryList = new ArrayList<Country>();
  dataAdapter = new MyCustomAdapter(this,
    R.layout.country_info, countryList);
  listView.setAdapter(dataAdapter);

  //enables filtering for the contents of the given ListView
  listView.setTextFilterEnabled(true);

  listView.setOnItemClickListener(new OnItemClickListener() {
   public void onItemClick(AdapterView<?> parent, View view,
     int position, long id) {
    // When clicked, show a toast with the TextView text
    Country country = (Country) parent.getItemAtPosition(position);
    Toast.makeText(getApplicationContext(),
      country.getCode(), Toast.LENGTH_SHORT).show();
   }
  });

  listView.setOnScrollListener(new OnScrollListener(){

   @Override
   public void onScrollStateChanged(AbsListView view, int scrollState) {}

   @Override
   public void onScroll(AbsListView view, int firstVisibleItem,
     int visibleItemCount, int totalItemCount) {

   int lastInScreen = firstVisibleItem + visibleItemCount;    
   if((lastInScreen == totalItemCount) && !(loadingMore)){     
    String url = "http://10.0.2.2:8080/CountryWebService" + 
     "/CountryServlet";
    grabURL(url); 
   }
   }
  });

  String url = "http://example.com";
  grabURL(url); 

 }

 public void grabURL(String url) {
  Log.v("Android Spinner JSON Data Activity", url);
  new GrabURL().execute(url);
 }

 private class GrabURL extends AsyncTask<String, Void, String> {
  private static final int REGISTRATION_TIMEOUT = 3 * 1000;
  private static final int WAIT_TIMEOUT = 30 * 1000;
  private final HttpClient httpclient = new DefaultHttpClient();
  final HttpParams params = httpclient.getParams();
  HttpResponse response;
  private String content =  null;
  private boolean error = false;
  private ProgressDialog dialog = 
   new ProgressDialog(AndroidListViewLoadMoreActivity.this);

  protected void onPreExecute() {
   dialog.setMessage("Getting your data... Please wait...");
   dialog.show();
  }

  protected String doInBackground(String... urls) {

   String URL = null;
   loadingMore = true;

   try {

   URL = urls[0];
   HttpConnectionParams.setConnectionTimeout(params, REGISTRATION_TIMEOUT);
   HttpConnectionParams.setSoTimeout(params, WAIT_TIMEOUT);
   ConnManagerParams.setTimeout(params, WAIT_TIMEOUT);

   HttpPost httpPost = new HttpPost(URL);

   //add name value pair for the country code
   List<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>(2);
   nameValuePairs.add(new BasicNameValuePair("page",String.valueOf(page)));

   httpPost.setEntity(new UrlEncodedFormEntity(nameValuePairs)); 
   response = httpclient.execute(httpPost);

    StatusLine statusLine = response.getStatusLine();
    if(statusLine.getStatusCode() == HttpStatus.SC_OK){
     ByteArrayOutputStream out = new ByteArrayOutputStream();
     response.getEntity().writeTo(out);
     out.close();
     content = out.toString();
    } else{
     //Closes the connection.
     Log.w("HTTP1:",statusLine.getReasonPhrase());
     response.getEntity().getContent().close();
     throw new IOException(statusLine.getReasonPhrase());
    }
   } catch (ClientProtocolException e) {
    Log.w("HTTP2:",e );
    content = e.getMessage();
    error = true;
    cancel(true);
   } catch (IOException e) {
    Log.w("HTTP3:",e );
    content = e.getMessage();
    error = true;
    cancel(true);
   }catch (Exception e) {
    Log.w("HTTP4:",e );
    content = e.getMessage();
    error = true;
    cancel(true);
   }

   return content;
  }

  protected void onCancelled() {
   dialog.dismiss();
   Toast toast = Toast.makeText(AndroidListViewLoadMoreActivity.this, 
     "Error connecting to Server", Toast.LENGTH_LONG);
   toast.setGravity(Gravity.TOP, 25, 400);
   toast.show();

  }

  protected void onPostExecute(String content) {
   dialog.dismiss();
   Toast toast;
   if (error) {
    toast = Toast.makeText(AndroidListViewLoadMoreActivity.this, 
      content, Toast.LENGTH_LONG);
    toast.setGravity(Gravity.TOP, 25, 400);
    toast.show();
   } else {
    displayCountryList(content);
   }
  }

 }

 private void displayCountryList(String response){

  JSONObject responseObj = null; 

  try {

   Gson gson = new Gson();
   responseObj = new JSONObject(response); 
   JSONArray countryListObj = responseObj.getJSONArray("countryList");

   //countryList = new ArrayList<Country>();
   if(countryListObj.length() == 0){
    ListView listView = (ListView) findViewById(R.id.listView1);
    listView.removeFooterView(loadMoreView);
   }
   else {
    for (int i=0; i<countryListObj.length(); i++){
    //get the country information JSON object
    String countryInfo = countryListObj.getJSONObject(i).toString();
    //create java object from the JSON object
    Country country = gson.fromJson(countryInfo, Country.class);
    //add to country array list
    countryList.add(country);
    dataAdapter.add(country);
    }
         page++;
    dataAdapter.notifyDataSetChanged();
    loadingMore = false;
   }

  } catch (JSONException e) {
   e.printStackTrace();
  }

 } 

}

將MyCustomAdapter.java作為適配器

private class MyCustomAdapter extends ArrayAdapter<Country> {

  private ArrayList<Country> countryList;

  public MyCustomAdapter(Context context, int textViewResourceId, 
    ArrayList<Country> countryList) {
   super(context, textViewResourceId, countryList);
   this.countryList = new ArrayList<Country>();
   this.countryList.addAll(countryList);
  }

  private class ViewHolder {
   TextView code;
   TextView name;
   TextView continent;
   TextView region;
  }

  public void add(Country country){
   Log.v("AddView", country.getCode());
   this.countryList.add(country);
  }

  @Override
  public View getView(int position, View convertView, ViewGroup parent) {

   ViewHolder holder = null;
   Log.v("ConvertView", String.valueOf(position));
   if (convertView == null) {

   LayoutInflater vi = (LayoutInflater)getSystemService(
     Context.LAYOUT_INFLATER_SERVICE);
   convertView = vi.inflate(R.layout.country_info, null);

   holder = new ViewHolder();
   holder.code = (TextView) convertView.findViewById(R.id.code);
   holder.name = (TextView) convertView.findViewById(R.id.name);
   holder.continent = (TextView) convertView.findViewById(R.id.continent);
   holder.region = (TextView) convertView.findViewById(R.id.region);

   convertView.setTag(holder);

   } else {
    holder = (ViewHolder) convertView.getTag();
   }

   Country country = this.countryList.get(position);
   holder.code.setText(country.getCode());
   holder.name.setText(country.getName());
   holder.continent.setText(country.getContinent());
   holder.region.setText(country.getRegion());

   return convertView;

  }

 }
}

創建Country.Java作為pojo -

public class Country {

 String code = null;
 String name = null;
 String continent = null;
 String region = null;
 Double lifeExpectancy = null;
 Double gnp = null;
 Double surfaceArea = null;
 int population = 0;

 public String getCode() {
  return code;
 }
 public void setCode(String code) {
  this.code = code;
 }
 public String getName() {
  return name;
 }
 public void setName(String name) {
  this.name = name;
 }
 public String getContinent() {
  return continent;
 }
 public void setContinent(String continent) {
  this.continent = continent;
 }
 public String getRegion() {
  return region;
 }
 public void setRegion(String region) {
  this.region = region;
 }
 public Double getLifeExpectancy() {
  return lifeExpectancy;
 }
 public void setLifeExpectancy(Double lifeExpectancy) {
  this.lifeExpectancy = lifeExpectancy;
 }
 public Double getGnp() {
  return gnp;
 }
 public void setGnp(Double gnp) {
  this.gnp = gnp;
 }
 public Double getSurfaceArea() {
  return surfaceArea;
 }
 public void setSurfaceArea(Double surfaceArea) {
  this.surfaceArea = surfaceArea;
 }
 public int getPopulation() {
  return population;
 }
 public void setPopulation(int population) {
  this.population = population;
 }

}

為主布局創建main.xml

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"

首先，您需要一個OnScrollListener方法，如下所示：

private OnScrollListener onScrollListener() {
    return new OnScrollListener() {

        @Override
        public void onScrollStateChanged(AbsListView view, int scrollState) {
            int threshold = 1;
            int count = listView.getCount();

            if (scrollState == SCROLL_STATE_IDLE) {
                if (listView.getLastVisiblePosition() >= count - threshold && pageCount < 2) {
                    Log.i(TAG, "loading more data");
                    // Execute LoadMoreDataTask AsyncTask
                    //It reached ListView bottom
                    getDataFromUrl(url_page2);
                }
            }
        }

        @Override
        public void onScroll(AbsListView view, int firstVisibleItem, int visibleItemCount,
                int totalItemCount) {
        }

    };
}

通過listView.setOnScrollListener(onScrollListener());設置列表視圖滾動監聽器listView.setOnScrollListener(onScrollListener());
