如何在recyclerview项目中获取文本视图的值？

Question

这是我的适配器RecyclerView.我怎样才能获得deckName另一项活动的价值？

public class ViewHolder extends RecyclerView.ViewHolder {
    public RelativeLayout deckLayout;
    public LinearLayout countsLayout;
    public ImageButton deckExpander;
    public ImageButton indentView;
    public  TextView deckName;
    public TextView deckNew, deckLearn, deckRev;

    public ViewHolder(View v) {
        super(v);
        deckLayout = (RelativeLayout) v.findViewById(R.id.DeckPickerHoriz);
        countsLayout = (LinearLayout) v.findViewById(R.id.counts_layout);
        deckExpander = (ImageButton) v.findViewById(R.id.deckpicker_expander);
        indentView = (ImageButton) v.findViewById(R.id.deckpicker_indent);
        deckName = (TextView) v.findViewById(R.id.deckpicker_name);
        deckNew = (TextView) v.findViewById(R.id.deckpicker_new);
        deckLearn = (TextView) v.findViewById(R.id.deckpicker_lrn);
        deckRev = (TextView) v.findViewById(R.id.deckpicker_rev);


    }
}

我想获取此值并将其与字符串进行比较:

final int itemCount = mDeckListAdapter.getItemCount();
DeckAdapter a = new DeckAdapter(getLayoutInflater(), getApplicationContext());
for(int i=0;i<itemCount;i++){
    //  final CharSequence text = DeckAdapter.ViewHolder.deckName.getText();
    if (text.equals(di)){
        mRecyclerView.findViewHolderForAdapterPosition(i).itemView.performClick();
    }
}

但是这段代码并没有真正起作用.

试试这个

String title = ((TextView) recyclerView.findViewHolderForAdapterPosition(position).itemView.findViewById(R.id.title)).getText().toString();

我喜欢用过

 recyclerView.addOnItemTouchListener(new RecyclerTouchListener(getApplicationContext(), recyclerView, new RecyclerTouchListener.ClickListener() {
        @Override
        public void onClick(View view, int position) {
          //  String title = ((TextView) view.findViewById(R.id.title)).getText().toString();
            String title1 = ((TextView) recyclerView.findViewHolderForAdapterPosition(position).itemView.findViewById(R.id.title)).getText().toString();
            Toast.makeText(getApplicationContext(), title1, Toast.LENGTH_SHORT).show();
        }

        @Override
        public void onLongClick(View view, int position) { }
    }));
