代码跳转到注册app中创建账号的错误语句坚持

Question

我正在尝试创建一个注册活动在我的安卓应用程序当我编译它运行没有和错误它似乎有一个逻辑问题，当我运行我的应用程序创建一个新帐户的瞬间它跳转到错误代码，因为我已经提供了我的注册活动代码在方法creatnewAccount()中的if语句中，我试图检查rpassword和密码是否相同。每当我运行我的应用程序并输入详细信息并单击注册按钮时，它都会跳转到else语句。我不明白错误是什么，我应该怎么做

Answer 1

替换这个

if (rpassword == password ){

    }
    else{
        Toast.makeText(this, "Password and Re-enter password are not same ", LENGTH_SHORT).show();

    }

有了这个

 if (rpassword.equals(password) ){

    }
    else{
        Toast.makeText(this, "Password and Re-enter password are not same ", LENGTH_SHORT).show();

    }
