Question

//这是我的班级

private String name;
private int height;
private float weight;
private int age;
private Sex gender;

public String getName() {
    return name;
}

public int getHeight() {
    return height;
}

public float getWeight() {
    return weight;
}

public int getAge() {
    return age;
}

public Sex getGender() {
    return gender;
}

public enum Sex {male, female, others}

;

public User(String name, Sex gender, int age, float weight, int height) {
    this.name = name;
    this.gender = gender;
    this.age = age;
    this.weight = weight;
    this.height = height;
     }
}

这是来自第一项活动

ArrayList<User> userList  = new ArrayList<User>();
 Intent intent = new Intent(ProfileSelect.this,MainActivity.class);
        intent.putExtra("list",userList);
        startActivity(intent);

现在我想将用户列表显示给另一个名为mainactivity的活动。如何检索mainactivity中的列表？ Tq提前..

Answer 1

您可以使用EventBus

// Post Object
EventBus.getDefault().postSticky(yourObject);

// Get Object
YourClass yourObject = EventBus.getDefault().getStickyEvent(YourClass.class);

将类的arraylist传递给android studio中的另一个活动
