单选按钮计数不起作用，单击按钮时自动重定向到第一个活动

Question

我正在尝试为我的Android应用检查单选按钮的数量。 我的应用程序中有15个单选按钮，我只想计算其中的前8个。 “测试”是EditText组件，我试图在其中显示所选单选按钮的数量。 FinalSubmit是已在其上实现侦听器的按钮。 以下是单选按钮的代码，以及我在onClickListener使用的代码：

public class Main2Activity extends AppCompatActivity {
    RadioButton rb1, rb2, rb3, rb4, rb5, rb6, rb7, rb8, rb9, rb10, rb11, rb12, rb13, rb14, rb15;

    int rbChecked = 0;

    Button finalsubmit;
    EditText test;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main2);

        finalsubmit = (Button)findViewById(R.id.button3);
        test = (EditText)findViewById(R.id.editText);
        rb1 = (RadioButton)findViewById(R.id.radioButton1);
        rb2 = (RadioButton)findViewById(R.id.radioButton2);
        rb3 = (RadioButton)findViewById(R.id.radioButton3);
        rb4 = (RadioButton)findViewById(R.id.radioButton4);
        rb5 = (RadioButton)findViewById(R.id.radioButton5);
        rb6 = (RadioButton)findViewById(R.id.radioButton6);
        rb7 = (RadioButton)findViewById(R.id.radioButton7);
        rb8 = (RadioButton)findViewById(R.id.radioButton8);
        rb9 = (RadioButton)findViewById(R.id.radioButton9);
        rb10 = (RadioButton)findViewById(R.id.radioButton10);
        rb11 = (RadioButton)findViewById(R.id.radioButton11);
        rb12 = (RadioButton)findViewById(R.id.radioButton12);
        rb13 = (RadioButton)findViewById(R.id.radioButton13);
        rb14 = (RadioButton)findViewById(R.id.radioButton14);
        rb15 = (RadioButton)findViewById(R.id.radioButton15);

        finalsubmit.setOnClickListener(new OnClickListener() {
        @Override
        public void onClick(View v) {
            if (rb1.isChecked()) {rbChecked++;}
            if (rb2.isChecked()) {rbChecked++;}
            if (rb3.isChecked()) {rbChecked++;}
            if (rb4.isChecked()) {rbChecked++;}
            if (rb5.isChecked()) {rbChecked++;}
            if (rb6.isChecked()) {rbChecked++;}
            if (rb7.isChecked()) {rbChecked++;}
            if (rb8.isChecked()) {rbChecked++;}

            test.setText(rbChecked);
        }
    });
}

现在的问题是，我单击提交按钮后，应用程序崩溃了，或者被重定向到了我应用程序的第一个活动。 拜托，有人，帮帮我，我已经完成了google并通过了StackOverflow，但是我被困住了。 下面是相同的logcat：

Answer 1

抱歉，我犯了一个错误，以下是我所做的更改。 现在，它的工作完全正常：

test.setText(String.valueOf(rbChecked));
