Android(安卓)Afinal框架学习(二) FinalActivity 一个IOC框架

框架地址：https://github.com/yangfuhai/afinal

对应的源码：

net.tsz.afinal.annotation.view.*

FinalActivity

FinalActivity是一个基础类，结合注解实现了，依赖注入(view的资源id，常用的监听器), 利用set方式注入

完全注解方式就可以进行UI绑定和事件绑定，无需findViewById和set event Listener

这个过程：initInjectedView>findViewById、setListener(activity, activity.field, eventLocalMethod, eventType)>

1.根据id得到view对象,设置到activity对应的field中

2. switch(eventType) {

case event:

view.set event listener(new EventListener(activity, eventLocalMethod));

EventListener implements many event listener>

在对应的event的重写方法中，反射调用eventLocalMethod

这些eventLocalMethod 的参数需要与对应的系统 event method 的参数一致

...

}

注解有哪些类型：

@Target(ElementType.FIELD)@Retention(RetentionPolicy.RUNTIME) public @interface ViewInject {public int id();public String click() default "";public String longClick() default "";public String itemClick() default "";public String itemLongClick() default "";public Select select() default @Select(selected="") ;}

调用注解：

package com.stone.afinal;import net.tsz.afinal.FinalActivity;import net.tsz.afinal.annotation.view.Select;import net.tsz.afinal.annotation.view.ViewInject;import android.os.Bundle;import android.view.View;import android.widget.AdapterView;import android.widget.ImageView;import android.widget.ListView;public class MainActivity extends FinalActivity {@ViewInject(id = R.id.imageview, click = "myClick",longClick = "myLongClick")ImageView imageview;@ViewInject(id = R.id.listview, click = "myClick",itemLongClick = "myItemLongClick",itemClick = "myItemClick",longClick = "myLongClick",select = @Select(selected="myItemSelected", noSelected="myNoSelected"))ListView listView;@Overrideprotected void onCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState);setContentView(R.layout.main);//继承FinalActivity，setContentView中初始化了} public void myClick(View v) {System.out.println("--myClick--");}public void myLongClick(View v) {System.out.println("--myLongClick--");}public void myItemLongClick(AdapterView<?> arg0, View arg1, int arg2,long arg3) {System.out.println("--myItemLongClick--");}public void myItemClick(AdapterView<?> arg0, View arg1, int arg2, long arg3) {System.out.println("--myItemClick--");}public void myItemSelected(AdapterView<?> arg0, View arg1, int arg2,long arg3) {System.out.println("--myItemSelected--");}public void myNoSelected(AdapterView<?> arg0) {System.out.println("--myNoSelected--");}}

在其他侵入式框架下使用（如ActionBarShelock）

     protected void onCreate(Bundle savedInstanceState) {       super.onCreate(savedInstanceState);        setContentView(view);        FinalActivity.initInjectedView(this);     }

在Fragment中使用

     public View onCreateView(LayoutInflater inflater, ViewGroup container,          Bundle savedInstanceState) {       View viewRoot = inflater.inflate(R.layout.map_frame, container, false);       FinalActivity.initInjectedView(this,viewRoot);    }
