Programming method for calling parent class method when Android refreshes sub-interface

In Android development, sometimes we need to refresh data in the sub-interface, and want to call the parent class's method to implement the refresh operation. This article will introduce how to implement such functionality in Android applications.

First, we need to create a parent class (ParentClass) and a child class (ChildClass). In the parent class, we define a method for refreshing the interface (refreshUI()), and call this method in the subclass to refresh the interface.

Here is a sample code:

// 父类
public class ParentClass {
   
    
    
    // 刷新界面的方法
    public void refreshUI() {
   
    
    
        // 这里可以执行刷新界面的操作
    }
