Android 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;
	
	@Override
	protected 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);
    }
