Java Android studio问答应用程序显示每个科目的分数

我的逻辑和代码有问题

大家好，我正计划创建一个测试真或假的应用程序，我已经做了，但我的问题是，我想显示每个主题的分数，问题是随机的，分组在一个数组中，我怎么可能做到呢？ 如何显示每个科目的分数，例如数学=2，科学=0，英语5 随机问题采用字符串格式 谢谢你的回答。祝大家今天愉快

        Collections.shuffle(Arrays.asList(quizarray));

**here is my code for the result it only shows passed or fail i want to show the score per subject thank you**


import android.content.Intent;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;
import android.widget.TextView;

public class ResultsActivity extends AppCompatActivity {
    TextView mGrade, mFinalScore;
    Button mRetryButton;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_results);


        mGrade = (TextView) findViewById(R.id.grade);
        mRetryButton = (Button)findViewById(R.id.retry);

        mGrade = (TextView)findViewById(R.id.grade);
        mRetryButton = (Button)findViewById(R.id.retry);


        Bundle bundle = getIntent().getExtras();
        int score = bundle.getInt("finalScore");



        if (score >= 10){
            mGrade.setText("You are passed");
        }
       else{
            mGrade.setText("try to review next time");
        }



        mRetryButton.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
                startActivity(new Intent(ResultsActivity.this, QuizActivity.class));
                ResultsActivity.this.finish();
            }
        });

    }
}

这是quizbook类的代码

public class QuizBook {
    private int mImage;
    private String mFact;
    private int mImage1;
    private String mFact1;


    public QuizBook (int mImage, String mFact) {
        this.mImage = mImage;
        this.mFact = mFact;

    }
    public int getmImage(){
        return mImage;
    }
    public String getmFact(){
        return mFact;
    }


    public static boolean[] answers = new boolean[]{
            true, true, true, true, true, true, true, true, true, true, true, true, true, true, true, true, true
    };

}

按主题制作计数器

私有整数mathScore=0； 私人智力科学分数=0

当你增加|减少分数时，像这样检查对象

 switch (question.getSubject) {
     case "math":
         mathScore++;
         break;
     case "math":
         mathScore++;
         break;
 }

谢谢，兄弟，我试试看，兄弟，我应该改变结构吗？你是说奎茨本吗？我看不到，但我想没有。你只需要得到第二个字符串值（主题）伴侣，你能帮我吗，你能给我一个样本吗？我真的非常感谢你的帮助，我很抱歉作为一个新手，我在QuizBook课堂上的表现如何。
