Java 如何将TextViewEx中的文本保存到剪贴板

这是我的代码，当我想在recyclerview中获取文本并保存在剪贴板中时出现了一些错误。 我的错误是：

这是adaptercode：

public class LinearCardListAdapter extends RecyclerView.Adapter<LinearCardListAdapter.MyViewHolder>{
private Context context;
private List<TravelCard> travelCards;
private RecyclerView recyclerView;
public class MyViewHolder extends RecyclerView.ViewHolder {
        public ImageView containerImageView;
        public TextView containerTextView;
    public LinearLayout textLayout;
    public int myHeight;
    public Button deleteItem;
    public TextViewEx subtitleView;
    public Button btnCopy;
    public MyViewHolder(View itemView) {
        super(itemView);
        textLayout = (LinearLayout) itemView.findViewById(R.id.text_layout);
        containerImageView = (ImageView) itemView.findViewById(R.id.image_container);
        btnCopy = (Button) itemView.findViewById(R.id.btn_copy);
        containerTextView = (TextView) itemView.findViewById(R.id.text_container);
        subtitleView = (TextViewEx) itemView.findViewById(R.id.subtitle_view);
        deleteItem = (Button) itemView.findViewById(R.id.btn_delete);
        myHeight = containerImageView.getHeight();
    }
}
public LinearCardListAdapter(Context context ,List<TravelCard> travelCards , RecyclerView recyclerView){
    this.context = context;
    this.recyclerView = recyclerView;
    this.travelCards = travelCards;
}
@Override
public LinearCardListAdapter.MyViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
    View myView = LayoutInflater.from(parent.getContext()).inflate(R.layout.linear_list_card_item, parent, false);
    MyViewHolder myViewHolder=  new MyViewHolder(myView);
    return myViewHolder;
}
@Override
public void onBindViewHolder(MyViewHolder holder, int position) {
    final int newPos = position;
    final MyViewHolder myViewHolder = holder;
    Glide.with(context).load(context.getResources().getIdentifier(context.getPackageName() + ":drawable/" + travelCards.get(position).getImagePath(),null,null)).into(holder.containerImageView);

}

containerTextView

是holder类属性之一。因此，您必须使用

holder.containerTextView

来访问它，而不是单独使用

containerTextView

因此，您必须修改此行（在

holder.btnCopy.setOnClickListener（…）

方法中）：

ClipData clip = ClipData.newPlainText("simple text", containerTextView.getText());

并将其更改为：

ClipData clip = ClipData.newPlainText("simple text", holder.containerTextView.getText());

ClipData clip = ClipData.newPlainText("simple text", containerTextView.getText());

ClipData clip = ClipData.newPlainText("simple text", holder.containerTextView.getText());
