java - 如何将多个字符串传递给另一个 Activity ？

我正在尝试制作一个测验 Android 应用程序。我正在尝试显示用户在另一项 Activity 中出错的问题和多项选择。我不知道如何转移多个错题。

这是我的测验 java 类。

public class QuizActivityMarketing extends Activity{
private Iterator<Question> questionIterator;
private TextView txtQuestion;
private RadioButton rda, rdb, rdc, rdd;
public Button butNext;
private int qid = 0;
private Question currentQ;
private int score = 0;

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

    // Define your views
    txtQuestion = (TextView) findViewById(R.id.textView1);
    rda = (RadioButton) findViewById(R.id.radio0);
    rdb = (RadioButton) findViewById(R.id.radio1);
    rdc = (RadioButton) findViewById(R.id.radio2);
    rdd = (RadioButton) findViewById(R.id.radio3);
    butNext = (Button) findViewById(R.id.button1);



            //Log question and option if wrong
            TextView question = (TextView) findViewById(R.id.textView1);
            RadioButton optA = (RadioButton) findViewById(R.id.radio0);
            RadioButton optB = (RadioButton) findViewById(R.id.radio1);
            RadioButton optC = (RadioButton) findViewById(R.id.radio2);
            RadioButton optD = (RadioButton) findViewById(R.id.radio3);
            if (!currentQ.getANSWER().trim().equals(answer.getText())) {
                Log.d("Current Question", ""+question.getText());
                Log.d("OptionA", ""+optA.getText());
                Log.d("OptionB", ""+optB.getText());
                Log.d("OptionC", "" + optC.getText());
                Log.d("OptionD", "" + optD.getText());
            }

            // Load the next question, if there are any
            if (questionIterator.hasNext()) {
                currentQ = questionIterator.next();
                setQuestionView(currentQ);
                qid++;
            }
            // Done asking questions
            Intent intent1 = getIntent();
            int buttonValue = Integer.valueOf(intent1.getExtras().getString("button"));
            if (qid > buttonValue)
            {

这是我的结果类

public class ResultActivityMarketing extends AppCompatActivity {

    //get text view for score
    TextView testResult = (TextView) findViewById(R.id.testResult);
    //get score
    Bundle extras = getIntent().getExtras();
    if (extras != null) {
        int score = extras.getInt("score");
        int numberquestions = extras.getInt("button");
        testResult.setText("You got " + score + " out of " + numberquestions + " questions correct");
    }
}

}

这是我的结果 Activity 的 XML 类。

    <ScrollView
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:id="@+id/scrollView" >

        <FrameLayout
            android:layout_width="wrap_content"
            android:layout_height="wrap_content">

            <TextView
            android:id="@+id/wrong_questions_result"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:textAppearance="?android:attr/textAppearanceMedium"
            android:text="Wrong Questions"
            android:paddingTop="10dp"/>
            <RadioGroup
            android:id="@+id/radioGroup1"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:layout_weight="0.04" >
                <RadioButton
                android:id="@+id/radio0"
                android:layout_width="match_parent"
                android:layout_height="wrap_content"
                android:checked="true"
                android:layout_marginTop="30dp"
                android:text="RadioButton" />
                <RadioButton
                android:id="@+id/radio1"
                android:layout_width="match_parent"
                android:layout_height="wrap_content"
                android:text="RadioButton" />
                <RadioButton
                android:id="@+id/radio2"
                android:layout_width="match_parent"
                android:layout_height="wrap_content"
                android:text="RadioButton" />
                <RadioButton
                android:id="@+id/radio3"
                android:layout_width="match_parent"
                android:layout_height="wrap_content"
                android:text="RadioButton"/>
            </RadioGroup>
        </FrameLayout>
    </ScrollView>
</LinearLayout>
