如何在RecyclerView中添加第二個佈局？

Question

我的RecyclerView存在一些問題。我想添加一個泡泡小部件，用消息創建一個新的圈子（就像在messanger中一樣）。問題是泡泡必須放在單獨的XML佈局文件中，所以我不能將它添加到我的適配器中的「項目」佈局中。內部氣泡佈局我只是TextView，但我不想顯示普通文本 - 這太容易了;）我想顯示從API獲取的數據。另一個字 - 我需要訪問我的適配器中的Bubble佈局中的TextView。請幫忙！ :)

這裏是我的適配器類

public class ConcertAdapter extends RecyclerView.Adapter<ConcertAdapter.MyViewHolder> { 


    private LayoutInflater inflater; 
    private Context context; 
    NetworkImageView mNetworkImageView; 
    private MySingleton mySingleton; 
    private List<Concert> concertList = new ArrayList(); 


    public ConcertAdapter(Context context, List<Concert> concerts) { 
     this.inflater = LayoutInflater.from(context); 
     this.concertList = concerts; 
     this.context = context; 

    } 

    public void setListConcert(ArrayList<Concert> concertList) { 
     this.concertList = concertList;

    } 


    @Override

     View view = inflater.inflate(R.layout.concert_item, parent, false); 
     MyViewHolder holder = new MyViewHolder(view); 

     return holder; 

    } 

    @Override 
    public void onBindViewHolder(final MyViewHolder holder, int position) { 

     final float screenWidthPx = holder.itemView.getResources().getDisplayMetrics().widthPixels; 

     Concert current = concertList.get(position); 
     Log.d("mLog", current.getUrl()); 
     holder.image.setImageUrl(current.getUrl(), MySingleton.getInstance().getImageLoader()); 
     holder.image.getLayoutParams().height = (int) (screenWidthPx * 0.75); 

     SimpleDateFormat format = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss"); 
     Date concertDate = new Date(); 
     try { 
      concertDate = format.parse(current.getDate()); 
     } catch (ParseException e) { 
      e.printStackTrace(); 
     } 
     DateTime dt = new DateTime(); 
     DateTime currentDate = dt.withZone(DateTimeZone.forID("Europe/Warsaw")); 
     int days = Days.daysBetween(new DateTime(currentDate), new DateTime(concertDate)).getDays(); 
     holder.date_btn.setText(String.valueOf(days)); 

    } 

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

    public void showDisplay(int position){ 
     Intent intent = new Intent(context, DisplayConcertActivity.class); 
     intent.putExtra("position", position); 
     intent.putExtra("content", concertList.get(position).getContent()); 
     intent.putExtra("date", concertList.get(position).getDate()); 
     intent.putExtra("url", concertList.get(position).getUrl()); 
     context.startActivity(intent); 
    } 


    class MyViewHolder extends RecyclerView.ViewHolder implements View.OnClickListener { 

     private NetworkImageView image; 
     private Button date_btn; 

     public MyViewHolder(View itemView) { 
      super(itemView); 
      image = (NetworkImageView) itemView.findViewById(R.id.concerts_niv); 
      date_btn = (Button) itemView.findViewById(R.id.date_btn); 
      image.setOnClickListener(this); 


     } 
     @Override 
     public void onClick(View v) {showDisplay(getAdapterPosition()); 

     } 
    } 


} 

這是我的泡泡佈局：

<com.txusballesteros.bubbles.BubbleLayout 
    xmlns:android="http://schemas.android.com/apk/res/android" 
    android:layout_width="wrap_content" 
    android:layout_height="wrap_content"> 

    <TextView 
     android:id="@+id/bubble_tv" 
     android:layout_width="70dp" 
     android:layout_height="70dp" 
     android:layout_gravity="center" 
     android:background="@drawable/profile_decorator" 
     android:scaleType="centerCrop" 
     android:src="@drawable/profile_decorator" 
     android:textColor="#fff" 
     /> 
</com.txusballesteros.bubbles.BubbleLayout> 

Answer 1

你可以通過你的泡沫TextView作爲aprameter到適配器構造函數。

private TextView mBubbleTextView; 

public ConcertAdapter(Context context, List<Concert> concerts, TextView bubbleTextView) { 
     this.inflater = LayoutInflater.from(context); 
     this.concertList = concerts; 
     this.context = context; 
     this.mBubbleTextView = bubbleTextView; 

} 

現在你有泡沫TextView在適配器中，所以可以從任何方法更新。
