Question

您好我无法弄清楚如何使用onItemClickListener监听卡片项目上的点击事件。卡片项是卡片视图中的任何视图。

我最近遇到了类似的要求，我能够使用以下方法解决问题。

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)));
            }
        });
    }
}
