Question

我在电台组创建了2组，其中一组问你是否擅长足球？另一个关于篮球的人。如果他们很好，我给了3分，我想计算我的计划的总分，但我不能。我需要帮助

private void addListenerOnButton() {
    final RadioGroup football = (RadioGroup) findViewById(R.id.radioGroup1);
    Button calc = (Button) findViewById(R.id.diabetriskbutton1);
    final RadioGroup basketball = (RadioGroup) findViewById(R.id.radioGroup2);
    calc.setOnClickListener(new OnClickListener() {

        @Override
        public void onClick(View arg0) {
            int IDfootball = football.getCheckedRadioButtonId();
            RadioButton football = (RadioButton) findViewById(IDfootball);
            if (IDfootball == R.id.item1yes) {
                int scorefootball = 3;

            } else if (IDfootball == R.id.item1no) { 
                int scorefootball = 2;

            } 

            int IDbasketball = basketball.getCheckedRadioButtonId();
            RadioButton basketball = (RadioButton) findViewById(IDbasketball);
            if (IDbasketball == R.id.item1yes) {
                int scorebasketball = 3;

            } else if (IDbasketball == R.id.item1no) { 
                int scorebasketball = 2;

            } 
            scoretotal = scorefootball + scorebasketball ;


        }
    });

}`

尝试删除这些行。我认为你的编译器会将你的onClick方法中的RadioGroup football | basketball变量与相同的局部变量混淆。

我也认为它们是不必要的，因为它们在宣布之后从未使用过。（您已经将从getCheckedRadioButtonId（）获得的ID与R.id.itemYes | No

进行比较

        RadioButton football = (RadioButton) findViewById(IDfootball);

        RadioButton basketball = (RadioButton) findViewById(IDbasketball);

另一点。你在if和else块中声明了scorefootball和scorebasketball。编译器不会在各自的块之外看到这些变量。这一行会引发错误：

        scoretotal = scorefootball + scorebasketball;

请在类似之外声明：

        int scorefootball = 2;//default value
        int scorebasketball = 2;//default value

        ...

        if (IDfootball == R.id.item1yes) {
            scorefootball = 3;

        } else if (IDfootball == R.id.item1no) { 
            scorefootball = 2;

        } 

        ...

        if (IDbasketball == R.id.item1yes) {
            scorebasketball = 3;

        } else if (IDbasketball == R.id.item1no) { 
            scorebasketball = 2;

        }

        scoretotal = scorefootball + scorebasketball ;

还可以发贴你的xml吗？我想知道你为什么要比较从不同RadioGroups的getCheckedRadioButtonId获得的ID与相同的R.id.item1Yes | No
