Android studio 安卓单选按钮点击状态捕捉

我正在开发一个考试应用程序，该程序让学生提供带答案的问题（放射组）（单选按钮），然后单击一个提交按钮（按钮），该按钮标记试卷并提供分数（文本视图）。 代码的问题在于，在“提交”按钮上单击，即使回答正确，分数仍然为零。 有什么解决办法吗

同时，代码如下：

public class MainActivity extends AppCompatActivity {
     int ts;
     TextView score;
     Button submit;
     RadioGroup grp1, grp2, grp3;
     RadioButton bt1, bt2, bt3, bt4, bt5, bt6, bt7, bt8;

     @Override
     protected void onCreate(Bundle savedInstanceState) {
         super.onCreate(savedInstanceState);
         setContentView(R.layout.activity_main);
         score = (TextView) findViewById(R.id.score);
         submit = (Button) findViewById(R.id.submit);
         grp1 = (RadioGroup) findViewById(R.id.grp1);
         grp2 = (RadioGroup) findViewById(R.id.grp2);
         grp3 = (RadioGroup) findViewById(R.id.grp3);
         bt1 =(RadioButton) findViewById(R.id.radioButton);
         bt2 =(RadioButton) findViewById(R.id.radioButton2);
         bt3 =(RadioButton) findViewById(R.id.radioButton3);
         bt4 =(RadioButton) findViewById(R.id.radioButton4);
         bt5 =(RadioButton) findViewById(R.id.radioButton5);
         bt6 =(RadioButton) findViewById(R.id.radioButton6);
         bt7 =(RadioButton) findViewById(R.id.radioButton7);
         bt8 =(RadioButton) findViewById(R.id.radioButton8);
         submit.setOnClickListener(new View.OnClickListener() {
             @Override
             public void onClick(View v) {
                 grp1.setOnCheckedChangeListener(new RadioGroup.OnCheckedChangeListener() {
                     @Override
                     public void onCheckedChanged(RadioGroup radioGroup, int checkedId) {
                         View Button = grp1.findViewById(checkedId);
                         int index = grp1.indexOfChild(Button);
                          switch (index) {
                             case 0:
                                 break;
                             case 1:
                                 break;
                             case 2:
                                 break;
                             case 3:
                                 ts++;
                                 break;
                         }
                     }
                 });
                 grp2.setOnCheckedChangeListener(new RadioGroup.OnCheckedChangeListener() {
                     @Override

                         int index = grp2.indexOfChild(Button);
                          switch (index) {
                             case 0:

耶稣基督，那个缩进…对不起，它有什么问题吗？当你发布一些代码时，你应该使用标记来格式化你的代码。否则很难（很）读懂…“非常感谢much@A.omar好的，代码是可用的。有什么解决办法吗？
