如何在Android的位置2的回收站视图中添加广告？

Question

我有一个回收站视图，在该视图中，我使用RSS阅读器获取新闻Feed，并在索引2的回收站视图中放置广告视图，但不知道如何放置它。请向我提供有关此问题的即时解决方案。

用于回收视图代码： -

private Context mContext; 
private View main; 
private RecyclerView m_newsList; 
private RecyclerView.LayoutManager m_layoutManager; 
private CNewsAdapter m_newsAdapter; 
String tagname; 
ArrayList<CNewsModel> feeds = new ArrayList<CNewsModel>(); 
private RelativeLayout m_mainLayout; 
private String URL = "http://gadgets.ndtv.com/rss/feeds"; 
private LinearLayout m_noInternetWarning; 
private ImageButton m_BtnRetry; 
private ProgressBar m_loadingProgress; 
CNewsModel feed; 

@Nullable 
@Override 
public View onCreateView(LayoutInflater inflater, @Nullable ViewGroup container, @Nullable Bundle savedInstanceState) { 
    main = inflater.inflate(R.layout.reward_news_activity, container, false); 
    mContext = getActivity(); 
    m_mainLayout = (RelativeLayout) main.findViewById(R.id.news_main_layout); 
    findViewById(); 
    readRss(); 
    return main; 
} 

/*Loading news through Rss reader*/ 
private void readRss() { 
    if (RewardUtil.isConnected(mContext)) { 
     new LoadFeed().execute(URL); 
    } else { 
     m_noInternetWarning.setVisibility(View.VISIBLE); 
     m_loadingProgress.setVisibility(View.GONE); 
    } 
} 

private void findViewById() { 
    m_BtnRetry = (ImageButton) main.findViewById(R.id.news_btn_retry); 
    m_BtnRetry.setOnClickListener(this); 
    m_noInternetWarning = (LinearLayout) main.findViewById(R.id.news_no_internet_warning); 
    m_loadingProgress = (ProgressBar) main.findViewById(R.id.news_loadingProgress); 

    m_newsList = (RecyclerView) main.findViewById(R.id.news_list); 
    m_layoutManager = new LinearLayoutManager(mContext); 
    m_newsList.setLayoutManager(m_layoutManager); 
} 

@Override 
public void onClick(View v) { 
    if (v == m_BtnRetry) { 
     if (RewardUtil.isConnected(mContext)) { 
      m_noInternetWarning.setVisibility(View.GONE); 
      m_loadingProgress.setVisibility(View.VISIBLE); 
      new LoadFeed().execute(URL); 
     } else { 
      CSnackBar.showSnackBarError(m_mainLayout, getResources().getString(R.string.no_internet_connection_warning)); 
     } 
    } 
} 

/*Loading news Throudgh Rss reader*/ 
private class LoadFeed extends AsyncTask<String, Void, ArrayList<CNewsModel>> { 
    @Override 
    protected ArrayList<CNewsModel> doInBackground(String... arg0) { 
     XmlPullParserFactory factory = null; 
     XmlPullParser parser = null; 
     try { 
      factory = XmlPullParserFactory.newInstance(); 
      factory.setNamespaceAware(true); 
      parser = factory.newPullParser(); 
      DefaultHttpClient client = new DefaultHttpClient(); 
      HttpGet method = new HttpGet(new URI(arg0[0])); 
      HttpResponse res = client.execute(method); 
      InputStream is = res.getEntity().getContent(); 
      parser.setInput(new InputStreamReader(is)); 
      int eventType = parser.getEventType(); 
      feed = new CNewsModel(); 
      String text = ""; 
      while (eventType != XmlPullParser.END_DOCUMENT) { 
       tagname = parser.getName(); 
       //Log.d(tagname, "tagname"); 
       switch (eventType) { 
        case XmlPullParser.START_TAG: 
         if (tagname.equalsIgnoreCase("item")) { 
          feed = new CNewsModel(); 
         } 
         break; 
        case XmlPullParser.TEXT: 
         text = parser.getText(); 
         break; 
        case XmlPullParser.END_TAG: 
         if (tagname.equalsIgnoreCase("item")) { 
          feeds.add(feed); 
         } else if (tagname.equalsIgnoreCase("title")) { 
          feed.setTitle(text); 
         } else if (tagname.equalsIgnoreCase("description")) { 
          feed.setDesc(text); 
         } else if (tagname.equalsIgnoreCase("link")) { 
          feed.setLinks(text); 
         } else if (tagname.equalsIgnoreCase("storyimage")) { 
          feed.setImage_list(text); 
         } else if (tagname.equalsIgnoreCase("pubDate")) { 
          feed.setPub_date(text); 
         } 
         break; 
        default: 
         break; 
       } 
       eventType = parser.next(); 
      } 
     } catch (XmlPullParserException | IOException | URISyntaxException e) { 
      e.printStackTrace(); 
     } 
     return feeds; 
    } 

    @Override 
    protected void onPostExecute(final ArrayList<CNewsModel> cNewsModels) { 
     super.onPostExecute(cNewsModels); 
     m_loadingProgress.setVisibility(View.GONE); 
     m_newsAdapter = new CNewsAdapter(mContext, cNewsModels, new RecyclerViewClickListener() { 
      @Override 
      public void recyclerViewListClicked(View v, int position) { 
       Toast.makeText(mContext, "Clicked::" + position, Toast.LENGTH_LONG).show(); 
       Intent i = new Intent(mContext, CNewsView.class); 
       i.putExtra("Link", cNewsModels.get(position).getLinks()); 
       mContext.startActivity(i); 
      } 
     }); 
     m_newsList.setAdapter(m_newsAdapter); 
    } 
} 

}

和代码适配器

private static final String TAG = CNewsAdapter.class.getSimpleName(); 
private Context mContext; 
private ArrayList<CNewsModel> models; 
private static RecyclerViewClickListener itemListener; 

public CNewsAdapter(Context context, ArrayList<CNewsModel> mList, RecyclerViewClickListener itemListener) { 
    this.mContext = context; 
    this.models = mList; 
    this.itemListener = itemListener; 
} 

@Override 
public ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) { 
    if (viewType == 2) { 
     View adView = LayoutInflater.from(parent.getContext()).inflate(R.layout.ad, parent, false); 
     return new AdsHolder(adView); 
    } else { 
     View itemView = LayoutInflater.from(parent.getContext()).inflate(R.layout.rewards_news_card, parent, false); 
     return new ItemHolder(itemView); 
    } 
} 

@Override 
public void onBindViewHolder(final ViewHolder holder, int position) { 
    CNewsModel pm = models.get(holder.getAdapterPosition()); 
    if (holder instanceof AdsHolder) { 
     final AdsHolder adsHolder = (AdsHolder) holder; 
     adsHolder.oNativeExpressAdview.setText("This is AdView"); 
    } else if (holder instanceof ItemHolder) { 
     final ItemHolder itemHolder = (ItemHolder) holder; 
     itemHolder.m_newsTitle.setText(pm.getTitle()); 
     itemHolder.m_newsTime.setText(pm.getPub_date()); 
     itemHolder.m_newsHeadline.setText(pm.getDesc()); 
     Picasso.with(mContext).load(pm.getImage_list()).into(itemHolder.m_newsImage, new Callback() { 
      @Override 
      public void onSuccess() { 
       Log.d(TAG, "OnSuccess Called::"); 
      } 

      @Override 
      public void onError() { 
       Log.d(TAG, "OnError Called::"); 

      } 
     }); 

    } 

} 

@Override 
public int getItemCount() { 
    return models.size(); 
} 

@Override 
public int getItemViewType(int position) { 
    if (position == 2) { 
     return 1; 
    } else { 
     return 2; 
    } 
} 

public class ViewHolder extends RecyclerView.ViewHolder { 
    public ViewHolder(View itemView) { 
     super(itemView); 
    } 
} 

private class AdsHolder extends ViewHolder { 
    private TextView oNativeExpressAdview; 

    public AdsHolder(View adView) { 
     super(adView); 
     oNativeExpressAdview = (TextView) adView.findViewById(R.id.adView); 
    } 
} 

private class ItemHolder extends ViewHolder implements View.OnClickListener { 
    private TextView m_newsTitle, m_newsTime, m_newsHeadline; 
    private ImageView m_newsImage; 

    public ItemHolder(View itemView) { 
     super(itemView); 
     m_newsTitle = (TextView) itemView.findViewById(R.id.tv_news_header); 
     m_newsTime = (TextView) itemView.findViewById(R.id.tv_news_time); 
     m_newsHeadline = (TextView) itemView.findViewById(R.id.tv_news_headline); 
     m_newsImage = (ImageView) itemView.findViewById(R.id.iv_news_image); 
     itemView.setOnClickListener(this); 

    } 

    @Override 
    public void onClick(View v) { 
     itemListener.recyclerViewListClicked(v, this.getLayoutPosition()); 
    } 
} 

}

Answer 1

@Override 
public int getItemViewType(int position) { 
    if (position == 2) { 
     return 2; 
    } else { 
     return 1; 
    } 
} 


    @Override 
    public RecyclerView.ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) { 
     if (viewType == 2) { 
      View view = LayoutInflater.from(parent.getContext()) 
        .inflate(R.layout.row_ads, parent, false); 

      return new AdsHolder(view); 
     } else { 
      View view = LayoutInflater.from(parent.getContext()) 
        .inflate(R.layout.row_mainlayout, parent, false); 

      return new MainHolder(view); 
     } 
    } 

    @Override 
    public void onBindViewHolder(final RecyclerView.ViewHolder holder, int position) { 

     CNewsModel pm = models.get(holder.getAdapterPosition()); 

     if (holder instanceof AdsHolder) { 

      final AdsHolder holder1 = (AdsHolder) holder; 

     }else if(holder instanceof MainHolder){ 

      final MainHolder holder2 = (MainHolder) holder; 
      holder2.m_newsTitle.setText(pm.getTitle()); 
     } 
    } 

Answer 2

create one layout which holds ad after that in adapter add 

     @Override 
      public int getItemViewType(int position) { 
       switch (position){ 
        case 0: 
         return 1; 
        case 1: 
         return 2; 

        default: 
         return 0; 
       } 
      } 


     @Override 
      public RecyclerAdapter.CustomViewHolder onCreateViewHolder(ViewGroup parent, int viewType) { 

       switch (viewType) { 
        case 1: 
        /*your main item*/ 
         View viewONE = LayoutInflater.from(parent.getContext()).inflate(R.layout.main_item, parent, false); 

         RecyclerAdapter.CustomViewHolder rowONE = new RecyclerAdapter.CustomViewHolder(viewONE); 
         return rowONE; 

        case 2: 
        /** your ad layout*/ 
         View viewTWO = LayoutInflater.from(parent.getContext()).inflate(R.layout.ad_layout, parent, false); 

         RecyclerAdapter.CustomViewHolder rowTWO = new RecyclerAdapter.CustomViewHolder(viewTWO); 
         return rowTWO; 
       } 
       return null; 
      } 


in onBind 
    @Override 
     public void onBindViewHolder(final RecyclerView.ViewHolder viewHolder, final int i) { 
      switch (viewHolder.getItemViewType()) { 
       case 1: 
        ItemHolder vh1 = (ItemHolder) viewHolder; 
        configureViewHolder1(vh1, i); 
        break; 

       case 2: 
        AdsHolder vh2 = (AdsHolder) viewHolder; 
        configureViewHolder2(vh2, i); 
        break; 
      } 
     } 

    > private void configureViewHolder1(final LoadingVH vh1, int 
    > position) { 
    >   //change your item data here } 
    > 
    > 
    > private void configureViewHolder2(final ViewHolder2 vh1, int 
    > position) { 
    >    // change ad data here 
    >     }
