The @FragmentArg annotation indicates that a fragment field should be injected with the corresponding Fragment Argument.

@FragmentArg 注解表明Fragment字段应该由相应的 Fragment Argument 注入。

The setter method in the generated builder will always have the same name as the argument. By default, the key used to bind the value is the field name, but you can change it by providing a value to the @FragmentArg annotation.

生成的构造器中的setter方法的命名会一直和参数一样。以往在默认情况下，键根据字段名绑定值，但是现在你可以通过提供一个值给 @FragmentArg 注解来改变这个现状。

@EFragment
public class MyFragment extends Fragment {
        @FragmentArg("myStringArgument")String myMessage;@FragmentArgString anotherStringArgument;@FragmentArg("myDateExtra")Date myDateArgumentWithDefaultValue = new Date();}

The fragment builder will hold dedicated methods for these arguments:

Fragment构造器对这些参数提供了专门的方法：

MyFragment myFragment = MyFragment_.builder().myMessage("Hello").anotherStringArgument("World").build();
