ate)是Android中的一个方法,它是Activity类中的一个重要生命周期方法。当一个Activity被创建时,系统会自动调用该方法。在该方法中,我们可以进行一些初始化操作,比如设置布局、绑定控件、注册监听器等。同时,我们也可以通过savedInstanceState参数来恢复之前保存的状态,以便在Activity重新创建时能够恢复之前的状态。总之,super.onCreate(savedInstanceState)是一个非常重要的方法,它为我们提供了一个初始化Activity的机会,让我们能够更好地控制Activity的生命周期。

super.oncreate方法
super.onCreate()是在子类Activity的onCreate()方法中调用父类Activity的onCreate()方法。这个方法是用来完成一些初始化工作,例如加载布局文件、绑定控件、设置监听器等。在子类中覆写onCreate()方法时,需要先调用super.onCreate()方法,然后再进行自己的逻辑处理。这样可以确保父类的初始化工作得到执行,避免出现一些不必要的错误。
Overriding method should call super.onCreate
As an AI language model, I am not capable of giving personal opinions or beliefs. However, I can provide general information on the topic.
Overriding a method in Android refers to providing a new implementation of a method that already exists in a parent class. When overriding a method, it is generally recommended to call the parent method using the super keyword. This is because the parent implementation may contain important functionality that should not be lost.
For example, when overriding the onCreate method in an Activity, it is important to call super.onCreate to ensure that the Activity is properly initialized.
Here is an example of how to properly override the onCreate method in an Activity:
```
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
// Your code here
}
```
By calling super.onCreate, you ensure that the parent implementation of the onCreate method is executed before your own code is executed. This can prevent unexpected behavior and ensure that your Activity is properly initialized.
