如何使用RadioGroup将Radio Button值与字符串进行比较

Question

我正在创建应用程序,当我在比较if语句中的值时,我从RadioGroup获取单选按钮值.这是我正在使用的Java代码.

if(radioQuizeGroup.getText() == "History"){
    Log.d("History", "Activity");
    Toast.makeText(StartQuize.this,"History sss ss ", Toast.LENGTH_SHORT).show();    
}
else{
    Log.d("History", "Error ");
}

并且我在错误日志中得到错误,
这是错误日志

请帮我

Answer 1

建议使用

if(radioQuizeGroup.getText().equals("History"))

而不是

if(radioQuizeGroup.getText() == "History")

由于==比较了对象的位置并比较了对象.equals()的值
