如何将TextViewEx中的文本保存到剪贴板

-2

这是我的代码和一些错误，当我想要在recyclerview中获取文本并保存在剪贴板中时。我的错误有：如何将TextViewEx中的文本保存到剪贴板

holder.btnCopy.setOnClickListener(new View.OnClickListener() { 
     @Override 
     public void onClick(View view) { 

      ClipboardManager clipboard = (ClipboardManager) getSystemService(CLIPBOARD_SERVICE); 
      ClipData clip = ClipData.newPlainText("simple text", containerTextView.getText()); 
      clipboard.setPrimaryClip(clip); 
      Toast.makeText(getApplicationContext(), "some", 
        Toast.LENGTH_LONG).show(); 

     } 
    });

，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);

holder.subtitleView.setText（travelCards.get（位置）.getSubtitle（），TRUE）;

holder.containerTextView.setText(travelCards.get(position).getTitle()); 
    recyclerView.addOnScrollListener(new RecyclerView.OnScrollListener() { 
     @Override 
     public void onScrollStateChanged(RecyclerView recyclerView, int newState) { 
      super.onScrollStateChanged(recyclerView, newState); 
     } 

     @Override 
     public void onScrolled(RecyclerView recyclerView, int dx, int dy) { 
      super.onScrolled(recyclerView, dx, dy); 

      Rect scrollBounds = new Rect(); 
      recyclerView.getHitRect(scrollBounds); 


      if (myViewHolder.containerImageView.getLocalVisibleRect(scrollBounds)) { 
       Display display = ((WindowManager) context.getSystemService(Context.WINDOW_SERVICE)).getDefaultDisplay(); 
       DisplayMetrics outMetrics = new DisplayMetrics(); 
       display.getMetrics(outMetrics); 

       float density = context.getResources().getDisplayMetrics().density; 


       float dpHeight = outMetrics.heightPixels/density; 
       int screen_height_pixels = (int) TypedValue.applyDimension(TypedValue.COMPLEX_UNIT_DIP, dpHeight, context.getResources().getDisplayMetrics()); 
       int half_screen_height = screen_height_pixels/2; 


       int container_height_pixels = (int) TypedValue.applyDimension(TypedValue.COMPLEX_UNIT_DIP, 200, context.getResources().getDisplayMetrics()); 


       int center = half_screen_height - (container_height_pixels/2); 


       int[] loc_screen = {0, 0}; 
       myViewHolder.containerImageView.getLocationOnScreen(loc_screen); 

       int final_loc = ((loc_screen[1] - center) * 100)/half_screen_height; 


       myViewHolder.containerImageView.setTranslationY(-final_loc * 0.6f * density - 160); 

      } 
     } 
    }); 
    holder.btnCopy.setOnClickListener(new View.OnClickListener() { 
     @Override 
     public void onClick(View view) { 

      ClipboardManager clipboard = (ClipboardManager) getSystemService(CLIPBOARD_SERVICE); 
      ClipData clip = ClipData.newPlainText("simple text", containerTextView.getText()); 
      clipboard.setPrimaryClip(clip); 
      Toast.makeText(getApplicationContext(), "متن در حافظه موقت دستگاه ذخیره شد", 
        Toast.LENGTH_LONG).show(); 

     } 
    }); 
    holder.deleteItem.setOnClickListener(new View.OnClickListener() { 
     @Override 
     public void onClick(View view) { 
      travelCards.remove(newPos); 
      notifyItemRemoved(newPos); 
      notifyItemRangeChanged(newPos, travelCards.size()); 
     } 
    }); 
} 



@Override 
public int getItemCount() { 
    return travelCards.size(); 
}

}

containerTextView是您的支持类属性之一。因此您必须单独使用holder.containerTextView来访问它，而不是containerTextView。

，所以你必须修改此行（holder.btnCopy.setOnClickListener(...)方法：

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

并将其更改为：

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