在android中執行卡片視圖項的onItemClickListener

Question

您好我無法弄清楚如何使用onItemClickListener偵聽卡片項目上的點擊事件。卡片項目是卡片視圖內的任何視圖。

我最近遇到了類似的需求，我可以使用以下方法解決問題。

public class MyViewHolder extends RecyclerView.ViewHolder { 

    public TextView titleTextView; 
    public ImageView coverImageView; 
    public ImageView likeImageView; 
    public ImageView shareImageView; 

    public MyViewHolder(View v) { 
     super(v); 
     titleTextView = (TextView) v.findViewById(R.id.titleTextView); 
     coverImageView = (ImageView) v.findViewById(R.id.coverImageView); 
     likeImageView = (ImageView) v.findViewById(R.id.likeImageView); 
     shareImageView = (ImageView) v.findViewById(R.id.shareImageView); 
     likeImageView.setOnClickListener(new View.OnClickListener() { 
      @Override 
      public void onClick(View v) { 


       int id = (int)likeImageView.getTag(); 
        if(id == R.drawable.ic_like){ 

         likeImageView.setTag(R.drawable.ic_liked); 
         likeImageView.setImageResource(R.drawable.ic_liked); 
         Toast.makeText(getActivity(),titleTextView.getText()+" added to favourites",Toast.LENGTH_SHORT).show(); 

        }else{ 

         likeImageView.setTag(R.drawable.ic_like); 
         likeImageView.setImageResource(R.drawable.ic_like); 
         Toast.makeText(getActivity(),titleTextView.getText()+" removed from favourites",Toast.LENGTH_SHORT).show(); 

        } 
      } 
     }); 

     shareImageView.setOnClickListener(new View.OnClickListener() { 
      @Override 
      public void onClick(View v) { 

       Uri imageUri = Uri.parse(ContentResolver.SCHEME_ANDROID_RESOURCE + 
         "://" + getResources().getResourcePackageName(coverImageView.getId()) 
         + '/' + "drawable" + '/' + getResources().getResourceEntryName((int)coverImageView.getTag())); 

       Intent shareIntent = new Intent(); 
       shareIntent.setAction(Intent.ACTION_SEND); 
       shareIntent.putExtra(Intent.EXTRA_STREAM,imageUri); 
       shareIntent.setType("image/jpeg"); 
       startActivity(Intent.createChooser(shareIntent, getResources().getText(R.string.send_to))); 
      } 
     }); 
    } 
}
