Arrow is a lightweight dependency injection library for Android.
Roboguice is no longer maintained, Dagger2 is a bit complicated, need to write component interface (so I wrote an automatic generation of component interface Dagger2Plus
1.@Inject:
inject object
2.@Singleton:
inject singleton object
3.Provider Interface:
avoid circular dependency for example：
public class A {
final B b;
@Inject
public A(B b) {
this.b = b;
}
public String print() {
return "I am A";
}
}
public class B {
Provider<A> a;
@Inject
public B(Provider<A> a) {
this.a = a;
}
}4.Application:
inject application，support to inject manager for future
5.@OnClick:
View setOnClickListener
6.@ContentView:
Activity or Fragment setContentView
7.@OnPostInject:
call this method after Inject action
8.@InjectExtra:
inject Bundle into Activity or Fragment
9.getInstance:
Arrow.getInstance(Class clazz)
10.@InjectView
use DataBinding instead of butterknife use Arrow to inject object
Arrow 是一个轻量级的Android DI 库，没有额外的引用。
最流行的Android DI框架中，Roboguice已经不再维护了，Dagger2使用有点复杂，需要写component interface（所以我写了一个自动生成component interface的库Dagger2Plus)，而且Dagger2使用代码生成，对于有代码洁癖的人来说不太喜欢。Arrow使用反射，在目前动不动就8核10核2G3G的硬件环境下，反射带来的性能缺陷不再明显，作为个人来说还是能接受的。
1、@Inject
对象注入
2、@Singleton
单例对象注入
3、Provider 接口
处理循环依赖 例如：
public class A {
final B b;
@Inject
public A(B b) {
this.b = b;
}
public String print() {
return "I am A";
}
}
public class B {
Provider<A> a;
@Inject
public B(Provider<A> a) {
this.a = a;
}
}4、Application注入
后续加入各种Service Manager的注入
5、@OnClick
View点击事件处理
6、@ContentView
支持Activity和Fragment setContentView
7、@OnPostInject
Inject 结束后触发该函数
8、@InjectExtra
支持Activity和Fragment 注入Bundle
9、getInstance
直接获取一个实例，可以是单例
Arrow.getInstance(Class clazz)
10、@InjectView
使用DataBinding替代butterknife Object的注入使用Arrow
