Question

在这里，我希望每当用户更改edittext的值时，textview的值也会随着使用乘以数量edittext而改变，但每当我想在更改edittext值之前出现错误消息时，找不到源代码 - VeiwRootImpl .deliverInputEvent（ViewRoot $ QueueInputEvent）行：3125

我也放了一些代码： -

edit_qty_regular_code.addTextChangedListener(new TextWatcher() {

        public void afterTextChanged(Editable s) {
            text_price_regular_code.setText (Integer.toString(qty));
        }

        public void beforeTextChanged(CharSequence s, int start, 
          int count, int after) {
            x=Integer.parseInt(text_price_regular_code.getText().toString());
        }

        public void onTextChanged(CharSequence s, int start, 
          int before, int count) 
        {
                qty=Integer.parseInt (edit_qty_regular_code.getText().toString());
                qty=(int) ((int)qty*(int)x);

        }
       });

但如果我将这四行代码放在复选框刻度事件中，那么我没有遇到问题...请告诉我我在哪里做错了
