Question

如何利用java反射机制取到静态内部类的静态变量？

package com.android.menuapp;
public final class R {
public static final class attr {
}
public static final class drawable {
public static final int chinesecategory_1=0x7f020000;
}
}
利用反射机制怎样取到drawable 中的静态变量？请各位高手不吝赐教，谢谢

Answer 1

通过 drawable s=new R.drawable(); 可得到drawable对象的实例，有了实例就可取得其内部变量

public final class R{
public static final class attr {
}
public static final class drawable {
public static final int chinesecategory_1=0x7f020000;
}

public static void main(String[] args) {
drawable s=new R.drawable();
int a=s.chinesecategory_1;
}
}
