クリックしてラジオボタンを変更したときに値を加算する

Question

私はラジオボタンから答えをチェックし、他のラジオボタンにチェックした答えを変更したいときにポイントの合計値が増加する（彼は両方の値を計算する）。私はそれぞれ7つのRadioGroupを持っていて、3つのRadioButtonを持っています。この計算をブロックすることは可能ですか？合計金額を増やすことなく、チェックされたラジオボタンを別のラジオボタンに変更する可能性があります。ここで

は私のコードです：

public class question1 extends AppCompatActivity { 

    //Necessary to calculate points 
    List<Integer> points; 
    int score = 0; 


    @Override 
    protected void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     setContentView(R.layout.activity_question1); 

     points = new ArrayList<Integer>(); 

     //Passing editText value to this activity 
     final TextView textView = (TextView) findViewById(R.id.pName); 
     Intent intent = getIntent(); 
     String str = intent.getStringExtra("name"); 
     textView.setText(str); 

     //Sending editText value to next activity 
     final Button start = (Button) findViewById(R.id.so); 
     start.setOnClickListener(new View.OnClickListener() { 
      @Override 
      public void onClick(View v) { 

       for (int index = 0; index < points.size(); index++) { 
        score = score + points.get(index); 

        Intent intent = new Intent(question1.this, fini.class); 
        intent.putExtra("name", textView.getText().toString()); 
        intent.putExtra("totalPoints", score); 
        startActivity(intent); 
       } 
      } 
     }); 
    } 
    // Calculate totalPoints based on checked answers 

    public List<Integer> onRadioButtonClicked(View view) { 
     // Is the button now checked? 
     boolean checked = ((RadioButton) view).isChecked(); 

     switch (view.getId()) {

私はあなたの問題ごとに私の答えを更新し、私もそれをテストしている、これを試してみてください。

public class question1 extends AppCompatActivity { 

    //Necessary to calculate points 
    List<Integer> points; 
    int score = 0; 
    int numberofquestions = 7; 


    @Override 
    protected void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     setContentView(R.layout.activity_question1); 

     points = new ArrayList<Integer>(); 

     for (int index = 0; index < numberofquestions; index++) { 
      points.add(index, 0); 
     } 

     //Passing editText value to this activity 
     final TextView textView = (TextView) findViewById(R.id.pName); 
     Intent intent = getIntent(); 
     String str = intent.getStringExtra("name"); 
     textView.setText(str); 

     //Sending editText value to next activity 
     final Button start = (Button) findViewById(R.id.so); 
     start.setOnClickListener(new View.OnClickListener() { 
      @Override 
      public void onClick(View v) { 

       for (int index = 0; index < points.size(); index++) { 
        score = score + points.get(index); 


       } 
       // Toast.makeText(getApplicationContext(), score + "", Toast.LENGTH_SHORT).show(); 

        Intent intent = new Intent(question1.this, fini.class); 
        intent.putExtra("name", textView.getText().toString()); 
        intent.putExtra("totalPoints", score); 
        score=0; 
        startActivity(intent); 
       //score = 0; 
      } 
     }); 
    } 
    // Calculate totalPoints based on checked answers 

    public List<Integer> onRadioButtonClicked(View view) { 
     // Is the button now checked? 
     boolean checked = ((RadioButton) view).isChecked(); 

     switch (view.getId()) { 
      case R.id.answerA1:
