ExitText复制粘贴

在exitText复制的时候  然后在粘贴确粘贴不上。看代码！
phoneNumberEdit.setOnCreateContextMenuListener(new OnCreateContextMenuListener(){
//            CharSequence  str = phoneNumberEdit.getText().toString();
            
            @Override
            public void onCreateContextMenu(ContextMenu menu, View v, ContextMenuInfo menuInfo) {
                menu.clear();
                // TODO Auto-generated method stub
                menu.setHeaderTitle("编辑文本");
                menu.add(0,ITEM1,0,"复制").setOnMenuItemClickListener(new MenuItem.OnMenuItemClickListener(){
                   // ClipboardManager clipboard = (ClipboardManager)context.getSystemService(Context.CLIPBOARD_SERVICE);
                    @Override
                    public boolean onMenuItemClick(MenuItem item) {
                        ClipboardManager clipboard = (ClipboardManager)context.getSystemService(Context.CLIPBOARD_SERVICE);
                        clipboard.setText(phoneNumberEdit.getText().toString());
                        return true;
                    }
                });
                menu.add(0,ITEM2,0,"粘贴").setOnMenuItemClickListener(new MenuItem.OnMenuItemClickListener(){
                    @Override
                    public boolean onMenuItemClick(MenuItem item) {
                        ClipboardManager clipboard = (ClipboardManager)context.getSystemService(Context.CLIPBOARD_SERVICE);
                        clipboard.getText();
                        
                        return true;
                    }
                });
            } 
       });
