Arrow
========
Arrow is a lightweight dependency injection library for Android.

Why
--------
Roboguice is no longer maintained, Dagger2 is a bit complicated, need to write component interface (so I wrote an automatic generation of component interface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](https://github.com/MasonLiuChn/Dagger2Plus)

Feature
--------
1.@Inject:

inject object

2.@Singleton:

inject singleton object

3.Provider Interface:

avoid circular dependency
for example：
```java
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

Arrow+DataBinding
--------
use DataBinding instead of butterknife
use Arrow to inject object

中文
------
Arrow 是一个轻量级的Android DI 库，没有额外的引用。

为什么
--------

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](https://github.com/MasonLiuChn/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。

特性
--------
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：
```java
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

Arrow+DataBinding
--------
使用DataBinding替代butterknife
Object的注入使用Arrow

Usage
--------

```groovy
repositories {
    maven {
        maven { url "https://github.com/MasonLiuChn/MasonMavenRepository/raw/maven/releases" }
    }
}
dependencies {
	compile 'com.masonliu:arrow:1.1.8'
}
```

```java
Arrow.init(Application application);
Arrow.inject(Activity object);
Arrow.injectFragmentOnCreateView(Object fragment, LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState)
Arrow.injectNoView(Object target)
Arrow.injectView(Object target)
Arrow.injectView(Object target,View view)
```
