android - java.lang.SecurityException：无法使 java.lang.Class 构造函数可访问

问题描述

我想要一个自定义 JAVA 类对象来存储应用程序中的所有数据。该对象需要传递到 Firebase 云 Firestore 数据库。

为了测试运行，我在按钮上添加了一个简单的 setOnCLickListener() 函数。UI 仅包含此按钮。

 button.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
                test test1 = new test("saheel", 23032001, 19, "GOLD", "abc");
/*test1.setAge(19);
test1.setName("saheel2");
test1.setDOB(23032001);
test1.setMembership("GOLD");
test1.setTrainer_name("abc");*/

                db.collection("u").document(test1.getName()).collection("profile").document("profile").set(test.class);
            }
        });

测试班——

public class test {
    private String name;
    private int DOB;
    private int age;
    private String membership;
    private String trainer_name;

    public test(String name, int DOB, int age, String membership, String trainer_name) {
        this.name = name;
        this.DOB = DOB;
        this.age = age;
        this.membership = membership;
        this.trainer_name = trainer_name;
    }

    public test(){
        //no-argument constructor
    }
   public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

    public int getDOB() {
        return DOB;
    }

    public void setDOB(int DOB) {
        this.DOB = DOB;
    }

    public int getAge() {
        return age;
    }

    public void setAge(int age) {
        this.age = age;
    }

    public String getMembership() {
        return membership;
    }

    public void setMembership(String membership) {
        this.membership = membership;
    }

    public String getTrainer_name() {
        return trainer_name;
    }

    public void setTrainer_name(String trainer_name) {
        this.trainer_name = trainer_name;
    }
}

单击按钮时，应用程序崩溃并且 logcat 显示以下错误 -
