RecyclerView適配器中的高亮度搜索文本

Question

我在我的應用程序中使用RecyclerView和自定義適配器... adapter be implements可搜索的可過濾。如何設置高亮度搜索文本？

這是我的代碼在自定義適配器過濾：

private Filter filterResult = new Filter() { 
     @Override 
     protected FilterResults performFiltering(CharSequence constraint) { 
      FilterResults filterResults = new FilterResults(); 
      ArrayList<Moment> tempList = new ArrayList<>(); 
      if (MOMENT_FILTER != null) { 
       if (TextUtils.isEmpty(constraint)) { 
        tempList = (ArrayList<Moment>) MOMENT_FILTER; 
       } else { 
        int length = MOMENT_LIST.size(); 
        int i = 0; 
        while (i < length) { 
         Moment item = MOMENT_FILTER.get(i); 
         if (item.getMoment().contains(constraint)) 
          tempList.add(item); 
         i++; 
        } 
       } 
      } 
      filterResults.values = tempList; 
      filterResults.count = tempList.size(); 
      return filterResults; 
     } 

     @SuppressWarnings("unchecked") 
     @Override 
     protected void publishResults(CharSequence constraint, FilterResults results) { 
      MOMENT_LIST = (ArrayList<Moment>) results.values; 
      if (results.count > 0) { 
       notifyDataSetChanged(); 
      } 
     } 
    }; 

    @Override 
    public Filter getFilter() { 
     return filterResult; 
    } 

這我在活動代碼文本變化（EditText上）：

EDT_SEARCH.addTextChangedListener(new TextWatcher() { 

      @Override 
      public void beforeTextChanged(CharSequence s, int start, int count, int after) { 
      } 

      @Override 
      public void onTextChanged(CharSequence s, int start, int before, int count) { 
       adapter.getFilter().filter(s); 
      } 

      @Override 
      public void afterTextChanged(Editable s) { 
      } 
}); 

結果與薩赫勒回答OK！

有SEARCHTEXT的參考適配器 然後在OnBindViewHolder你可以做

String text = list.get(position).getText(); // Your getter Method 
String htmlText = text.replace(searchText,"<font color='#c5c5c5'>"+searchText+"</font>"); 
// Only searchText would be displayed in a different color. 
holder.textView.setText(Html.fromHtml(htmlText);
