screenshot 如何从多个无线电组中获取值以及如何解决仅返回第一个值

 public void onClick(View v) 

            int widepart=radioWidePart.getCheckedRadioButtonId();
            int jawShape=radioJawShape.getCheckedRadioButtonId();
            int faceLength=radiofaceLength.getCheckedRadioButtonId();
            RadioButton foreheard = (RadioButton)findViewById(widepart);
            RadioButton cheekbones = (RadioButton)findViewById(widepart);
            RadioButton pointy=(RadioButton)findViewById(jawShape);
            RadioButton square=(RadioButton)findViewById(jawShape);
            RadioButton flshort=(RadioButton)findViewById(faceLength);
            RadioButton flaverage=(RadioButton)findViewById(faceLength);
            if(foreheard.isChecked())
                if(pointy.isChecked())
                    if(flshort.isChecked())
                        Intent Intents=new Intent(form.this,heart.class);
                        startActivity(Intents);
                        setContentView(R.layout.activity_heart);
                    
                    else if(flaverage.isChecked())
                        Intent Intents=new Intent(getApplicationContext(),heart.class);
                        startActivity(Intents);
                        setContentView(R.layout.activity_heart);
                    
                

【问题讨论】：

你能解释一下你的代码没有什么吗？什么是不受欢迎的行为？

我想从多个radioGroups 中获取值，例如分别为foreheard 和pointy 形式的widepart 组和jawshape 组。我想根据多个组中选中的单选按钮进入下一个活动。当前代码只返回第一个值。

【参考方案1】：

final RadioGroup radioWidePart= (RadioGroup) findViewById(R.id.widestpart);
final RadioButton forehead=(RadioButton)findViewById(R.id.foreheard);
final RadioButton cheekbone=(RadioButton)findViewById(R.id.cheekbone);
final RadioGroup radioJawShape=(RadioGroup) findViewById(R.id.shapeOfJaw);
final RadioButton pointy=(RadioButton)findViewById(R.id.pointy);
final RadioButton square=(RadioButton)findViewById(R.id.square);
final RadioGroup radiofaceLength=(RadioGroup)findViewById(R.id.faceLength);
final RadioButton flshort=(RadioButton)findViewById(R.id.flshort);
Button btnSubmit=(Button) findViewById(R.id.btnSubmit);
btnSubmit.setOnClickListener(new View.OnClickListener()
        public void onClick(View v) 
            if(pointy.isChecked())
                Intent Intents= new Intent(form.this, heart.class);
                startActivity(Intents);
