Question

当我运行Price方法时，我得到了IllegealStateException，但是当我只用显示方法运行它时，我没有得到任何错误

import csv
from datetime import date

while True:
    amt=int(input("\nENTER THE AMOUNT "))
    if amt>monthlyincome:
        print("YOU HAVE SPENT MORE THAN YOUR MONTHLY INCOME!PLEASE TRY AGAIN")
    else:
        break

while True:
    dat=input("ENTER DATE (DD/MM/YYYY):")
    d=date.today()
    format="%d/%m/%y"
    time1=d.strftime(format)
    if dat>time1:
        print("PLEASE ENTER A VALID DATE")
    else:
        break

data=[amt,dat]
exp.append(data)
for i in exp:
    d.writerow(str(i))

Answer 1

尝试一下

private void Price(int number) {
    TextView priceEditText = (TextView) findViewById(R.id.price_text_view);
    priceEditText.setText(number.toSting());
}

Answer 2

按如下所示重构代码。

private void Price(int number) {
    TextView priceEditText = (TextView) findViewById(R.id.price_text_view);
    priceEditText.setText(String.valueOf(number));
}

添加其他功能时出现错误
