分享一个android的工具类（扩充根据R类中的id寻址xml）

android提供的根据id找简单资源如下

String about = getString(R.string.about);
String[] aryShop = getResources().getStringArray(R.array.level); 

分享一个自己扩充的可以针对性的选个多个ID资源

package lidongbo.util;

import java.lang.reflect.Field;
import java.util.ArrayList;
import java.util.List;
import java.util.StringTokenizer;

import lidongbo.test.R;
import lidongbo.test.R.drawable;

		List<Integer> result=new ArrayList<Integer>();
		Field[] fileds = innerClass.getDeclaredFields();
		for (int i = 0; i < fileds.length; i++) {
			result.add(fileds[i].getInt(innerClass));
		}
		return result.toArray(new Integer[0]);
	}
