Answer 1

你用相同的ID（radioButton1）做這樣的滿足您的所有RadioGroup

rg1.setOnCheckedChangeListener(new RadioGroup.OnCheckedChangeListener() { 

       @Override 
       public void onCheckedChanged(RadioGroup group, int checkedId) { 
        // TODO Auto-generated method stub 

        int childCount=group.getChildCount(); 
        for (int i=0;i<childCount;i++){ 

          RadioButton r_btn = (RadioButton) group.getChildAt(i); 
          if (r_btn.getId() == checkedId) { 
           // do your stuf here 
           sum1=i+1; // since position is from 0. 
          } 

        } 

       } 
      }); 

rg2.setOnCheckedChangeListener(new RadioGroup.OnCheckedChangeListener() { 

       @Override 
       public void onCheckedChanged(RadioGroup group, int checkedId) { 
        // TODO Auto-generated method stub 

        int childCount=group.getChildCount(); 
        for (int i=0;i<childCount;i++){ 

          RadioButton r_btn = (RadioButton) group.getChildAt(i); 
          if (r_btn.getId() == checkedId) { 
           // do your stuf here 
           sum2=i+1; // since position is from 0. 
          } 

        } 

       } 
      }); 


hitung.setOnClickListener(new OnClickListener() { 

     @Override 
     public void onClick(View v) { 

      total.setText(""+sum1+sum2); 

     } 
    }); 

Answer 2

你可以有收音機組的參考和使用getCheckedRadioButtonId() THX得到檢查單選按鈕ID。看看這裏

RadioGroup radioGroup = findViewById(R.id.radio_group); 

然後，當你需要得到選定的收音機選項。

int id = radioGroup.getCheckedRadioButtonId(); 
if (id == -1){ 
    //no item selected 
} 
else{ 
    if (id == R.id.radio_button1){ 
     //Do something with the button 
    } 
} 

單選按鈕，首先改變你的按鈕的ID。對於所有您按鈕的
