可以不从FinalActivity继承吗？

Question

前面有兄弟问了，如果必须从FinalActivity继承的话，可能会和其他应用冲突。

我把FinalActivity改了改，加了一个新类，在Activity的onCreate中调用就可以了，调用方法如下：

new FinalActivityHelper(this).initView();

 
FinalActivityHelper类的代码如下，这个类的代码都是从FinalActivity拷贝过来的，只改了几个小地方。

package net.tsz.afinal;

import java.lang.reflect.Field;

import net.tsz.afinal.annotation.view.EventListener;
import net.tsz.afinal.annotation.view.Select;
import net.tsz.afinal.annotation.view.ViewInject;
import android.app.Activity;
import android.text.TextUtils;
import android.view.View;
import android.widget.AbsListView;

public class FinalActivityHelper {
	
	private Activity activity ;
	
	public FinalActivityHelper(Activity activity)
	{
		this.activity = activity; 
	}

	public void initView()
	{
		Field[] fields = activity.getClass().getDeclaredFields();
		if(fields == null ||  fields.length == 0)
			return ;
		
		for(Field field : fields)
		{
			ViewInject viewInject = field.getAnnotation(ViewInject.class);
			if(viewInject == null)
				continue ;
			
			int viewId = viewInject.id();
			View view = activity.findViewById(viewId);
			
			if ( view == null )
				continue ;
			
			try {
				field.setAccessible(true);
				field.set(activity,view );
			} catch (Exception e) {
				e.printStackTrace();
			}
			
			String clickMethod = viewInject.click();
			if(!TextUtils.isEmpty(clickMethod))
				setViewClickListener(view,clickMethod);
			
			String longClickMethod = viewInject.longClick();
			if(!TextUtils.isEmpty(longClickMethod))
				setViewLongClickListener(view,longClickMethod);
			
			String itemClickMethod = viewInject.itemClick();
			if(!TextUtils.isEmpty(itemClickMethod))
				setItemClickListener(view,itemClickMethod);
			
			String itemLongClickMethod = viewInject.itemLongClick();
			if(!TextUtils.isEmpty(itemLongClickMethod))
				setItemLongClickListener(view,itemLongClickMethod);
			
			Select select = viewInject.select();
			if(!TextUtils.isEmpty(select.selected()))
				setViewSelectListener(view,select.selected(),select.noSelected());
		}	
	}
	
	
	private void setViewClickListener(View view,String clickMethod)
	{
		view.setOnClickListener(new EventListener(activity).click(clickMethod));
	}
	
	private void setViewLongClickListener(View view,String clickMethod)
	{
		view.setOnLongClickListener(new EventListener(activity).longClick(clickMethod));
	}
	
	private void setItemClickListener(View view,String itemClickMethod)
	{
		if(view instanceof AbsListView)
		{
			((AbsListView)view).setOnItemClickListener(new EventListener(activity).itemClick(itemClickMethod));
		}
	}
	
	private void setItemLongClickListener(View view,String itemClickMethod)
	{
		if(view instanceof AbsListView)
		{
			((AbsListView)view).setOnItemLongClickListener(new EventListener(activity).itemLongClick(itemClickMethod));
		}
	}
	
	private void setViewSelectListener(View view,String select,String noSelect)
	{
		if(view instanceof AbsListView)
		{
			((AbsListView)view).setOnItemSelectedListener(new EventListener(activity).select(select).noSelect(noSelect));
		}

	}
}

 

另外，FinalActivity 第144行setViewSelectLister函数中

if(obj instanceof View){

是否应该改为

if(view instanceof AbsListView)
