我们需要把代码里面的R.xx.xx改成以下方式读取：

1 package com.xlcw.sdk.tool; 2  3 import java.lang.reflect.Field; 4 import android.content.Context; 5 import android.util.Log; 6  7 public class GetItemId{ 8      9     public static Context paramContext;10     11     public static void setContext(Context paramContext)12     {13         GetItemId.paramContext = paramContext;14     }15     16     public static int getItemId(String paramString1,17             String paramString2) {18         try {19             Class
