如何把使用到android res文件夹下面资源（R.xx.xx)的工程打包成jar文件，供其它项目使用

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<?> localClass = Class.forName(paramContext.getPackageName()
20                     + ".R$" + paramString1);
21             Field localField = localClass.getField(paramString2);
22             int i = Integer.parseInt(localField.get(localField.getName())
23                     .toString());
24             return i;
25         } catch (Exception localException) {
26             Log.e("getIdByReflection error", localException.getMessage());
27         }
28         return 0;
29     }
30
31     public static int[] getItemIdArray(String paramString1, String paramString2) {
32         try {
33             Class<?> localClass = Class.forName(paramContext.getPackageName()
34                     + ".R$" + paramString1);
35             Field localField = localClass.getField(paramString2);
36             int[] i = (int[]) localField.get(localField.getName().toString());
37             return i;
38         } catch (Exception localException) {
39             Log.e("getIdByReflection error", localException.getMessage());
40         }
41         return null;
42     }
43
44     public static int getLayoutResIDByName(String name) {
45         return paramContext.getResources().getIdentifier(name, "layout",
46                 paramContext.getPackageName());
47     }
48
49     public static int getIdResIDByName(String name) {
50         return paramContext.getResources().getIdentifier(name, "id",
51                 paramContext.getPackageName());
52     }
53
54     public static int getStringResIDByName(String name) {
55         return paramContext.getResources().getIdentifier(name, "string",
56                 paramContext.getPackageName());
57     }
58
59     public static int getDrawableResIDByName(String name) {
60         return paramContext.getResources().getIdentifier(name, "drawable",
61                 paramContext.getPackageName());
62     }
63
64 }
