FinalActivity

FinalActivity是一個基礎類，結合註解實現了，依賴注入(view的資源id，經常使用的監聽器), 利用set方式注入

全然註解方式就能夠進行UI綁定和事件綁定，無需findViewById和set event Listener

這個過程：initInjectedView>findViewById、setListener(activity, activity.field, eventLocalMethod, eventType)>

1.依據id得到view對象,設定到activity相應的field中

2. switch(eventType) {

case event:

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

EventListener implements many event listener>

在相應的event的重寫方法中，反射調用eventLocalMethod

這些eventLocalMethod 的參數須要與 相應的系統 event method 的參數一致

 

...

}

註解有哪些類型：

@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="") ;}

調用註解：

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);//繼承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--");}}

在其它侵入式架構下使用（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);    }
