java - 如何从对象中获取变量？

Question

我正在自定义列表适配器中创建 image_details。在此适配器期间，为每个项目设置变量 Answer。通过调试器，我看到数据位于需要的位置，但我不知道如何访问它:

调试器图像:

在这里您可以看到我有 6 个问题，每个问题都有变量 int Answer(打开的一个设置为 0)。我想在按下保存时请求每个项目(全部 6 个)的答案:

SaveButton = ((Button) rootView.findViewById(R.id.Save));
SaveButton.setOnClickListener(new View.OnClickListener() {
    @Override
    public void onClick(View v) {
        Object c = image_details.get(1);
    }
});

我应该在 onClick 中放置什么来检索此数据？

这是我的QuestionItem类:

public class QuestionItem {
    private String Question;
    private String Answer1;
    private String Answer2;
    private String Answer3;
    private String Answer4;
    private int Answer;
    private String[] Answers;

    public String getQuestion() {
        return Question;
    }

    public void setQuestion(String Question) {
        this.Question = Question;
    }

    public String Getanswer1() {
        return Answer1;
    }

    public void setAnswer1(String Answer1) {
        this.Answer1 = Answer1;
    }

    public String Getanswer2() {
        return Answer2;
    }

    public void setAnswer2(String Answer2) {
        this.Answer2 = Answer2;
    }

    public String Getanswer3() {
        return Answer3;
    }

    public void setAnswer3(String Answer3) {
        this.Answer3 = Answer3;
    }

    public String Getanswer4() {
        return Answer4;
    }

    public void setAnswer4(String Answer4) {
        this.Answer4 = Answer4;
    }

    public int GetAnswer() {
        return Answer;
    }

    public void setAnswer(int Answer) {
        this.Answer = Answer;
    }
}

Answer 1

使用实例变量。这是一个例子

public class Employee{
   // this instance variable is visible for any child class.
  public String name;

// salary  variable is visible in Employee class only.
private double salary;

// The name variable is assigned in the constructor. 
public Employee (String empName){
   name = empName;
}

// The salary variable is assigned a value.
public void setSalary(double empSal){
   salary = empSal;
} 

// This method prints the employee details.
public void printEmp(){
  System.out.println("name  : " + name );
  System.out.println("salary :" + salary);
}

public static void main(String args[]){
   Employee empOne = new Employee("Ransika");
   empOne.setSalary(1000);
  empOne.printEmp();
 } 
}
