in the working copy of 'KeyBinding.cpp', LF will be replaced by CRLF the next time Git touches it怎么解

这是 Git 在 Windows 操作系统下处理换行符时的一个警告。Windows 和 Unix 系统在处理文本文件时采用了不同的换行符，分别是 CRLF 和 LF。Git 默认会自动地将这两种换行符在提交时转换为 LF，而在检出时转换为 CRLF。但如果在 Windows 系统下，你的 Git 工作区中存在某些文件使用了 LF 换行符，那么 Git 在下一次接触这个文件时就会警告你，提示“LF will be replaced by CRLF”。

这个警告不会影响你的代码正常运行，但是如果你需要保持文件的原始换行符，可以在 Git 配置中进行设置。你可以使用以下命令取消警告并禁用自动转换：

git config core.autocrlf false

如果你想要强制进行换行符转换，可以使用以下命令：

git config core.autocrlf true

DSL element 'android.dataBinding.enabled' is obsolete and has been replaced with 'android.buildFeatures.dataBinding'. It will be removed in version 5.0 of the Android Gradle plugin. Affected Modules: app

Hello! It seems like you are facing an issue with the Android Gradle plugin. The DSL element 'android.dataBinding.enabled' has been replaced with 'android.buildFeatures.dataBinding' and will be removed in version 5.0 of the Android Gradle plugin.

To fix this issue, you need to update your Gradle plugin configuration in your app module's build.gradle file. Replace the old DSL element with the new one as follows:

android {
    // ...
    buildFeatures {
        dataBinding true
    }
}

By doing this, you enable data binding for your Android project using the updated DSL element. Make sure to sync your project after making this change.

Please let me know if you need any further assistance!

All method binding in Java uses late binding unless the method is static or final (private methods are implicitly final).

Yes, that's correct. In Java, all non-static and non-final methods use late binding (also known as dynamic binding or run-time binding) by default. This means that the method implementation to be called is decided at runtime based on the actual type of the object that the method is being called on.

For example, consider the following code:

class Animal {
    public void makeSound() {
        System.out.println("Animal is making a sound");
    }
}

class Cat extends Animal {
    public void makeSound() {
        System.out.println("Meow!");
    }
}

class Dog extends Animal {
    public void makeSound() {
        System.out.println("Woof!");
    }
}

public class Main {
    public static void main(String[] args) {
        Animal animal1 = new Cat();
        Animal animal2 = new Dog();
        animal1.makeSound(); // output: Meow!
        animal2.makeSound(); // output: Woof!
    }
}

In this example, we have a parent class `Animal` and two child classes `Cat` and `Dog`. Each class has its own implementation of the `makeSound()` method. In the `main()` method, we create two objects of type `Animal`, but their actual types are `Cat` and `Dog`, respectively. When we call the `makeSound()` method on these objects, the implementation that gets called is based on the actual type of the object, not the declared type of the variable.

However, if a method is declared as static or final, it uses early binding (also known as static binding or compile-time binding) instead of late binding. In the case of a static method, the method implementation to be called is determined at compile time based on the declared type of the variable. In the case of a final method, the method implementation is also determined at compile time, but cannot be overridden by any subclasses.
