在开发SDK中，如果需求中要开发者去实现界面，然后再给别人调用。这样的需求，我们必须去写一个工具类来获取各个资源文件夹下的id。通过底层获取id的代码实现，这样游戏接了才不会导致找不到资源ID。

import android.content.Context;import java.lang.reflect.Field;public class ResourceUtil {    public ResourceUtil() {    }    public static int getLayoutResIDByName(Context context, String name) {        return context.getResources().getIdentifier(name, "layout", context.getPackageName());    }    public static int getIdResIDByName(Context context, String name) {        return context.getResources().getIdentifier(name, "id", context.getPackageName());    }    public static int getStringResIDByName(Context context, String name) {        return context.getResources().getIdentifier(name, "string", context.getPackageName());    }    public static int getDrawableResIDByName(Context context, String name) {        return context.getResources().getIdentifier(name, "drawable", context.getPackageName());    }    public static int getRawResIDByName(Context context, String name) {        return context.getResources().getIdentifier(name, "raw", context.getPackageName());    }    public static int getAnimResIDByName(Context context, String name) {        return context.getResources().getIdentifier(name, "anim", context.getPackageName());    }    public static int getStyleResIDByName(Context context, String name) {        return context.getResources().getIdentifier(name, "style", context.getPackageName());    }    public static int getColorResIDByName(Context context, String name) {        return context.getResources().getIdentifier(name, "color", context.getPackageName());    }    public static int getIntegerResIDByName(Context context, String name) {        return context.getResources().getIdentifier(name, "integer", context.getPackageName());    }    public static int getBoolResIDByName(Context context, String name) {        return context.getResources().getIdentifier(name, "bool", context.getPackageName());    }    public static int getDimenResIDByName(Context context, String name) {        return context.getResources().getIdentifier(name, "dimen", context.getPackageName());    }    private static Object getResourceId(Context context, String name, String type) {        String className = context.getPackageName() + ".R";        try {            Class e = Class.forName(className);            Class[] var8;            int var7 = (var8 = e.getClasses()).length;            for(int var6 = 0; var6 < var7; ++var6) {                Class childClass = var8[var6];                String simple = childClass.getSimpleName();                if(simple.equals(type)) {                    Field[] var13;                    int var12 = (var13 = childClass.getFields()).length;                    for(int var11 = 0; var11 < var12; ++var11) {                        Field field = var13[var11];                        String fieldName = field.getName();                        if(fieldName.equals(name)) {                            System.out.println(fieldName);                            return field.get((Object)null);                        }                    }                }            }        } catch (Exception var15) {            var15.printStackTrace();        }        return null;    }    public static int getStyleableResIDByName(Context context, String name) {        return ((Integer)getResourceId(context, name, "styleable")).intValue();    }    public static int[] getStyleableArrayResIDByName(Context context, String name) {        return (int[])getResourceId(context, name, "styleable");    }}
