当按下删除按钮时，无法按下太长的按钮点

Question

我正在做一个计算器应用程序，并且所有按钮都是功能，但是当我按下Delete的时间太长时，无法按下指向按钮。谁能帮我？谢谢。

这是我到目前为止所做的，我应该做些更改吗？对我的英语不好对不起。

有任何错误

delete.setOnLongClickListener(new View.OnLongClickListener() {
        @Override
        public boolean onLongClick(View v) {
            if(onNumSelectedListener != null){
                onNumSelectedListener.onDeleteAll();
                return true;
            }
            return false;
        }
    });
