如何循环通过R.string。<name>

我试图在字符串中循环通过以下项。但获取无效int错误。最佳解决方案或变通方法是什么?

<string name="hero_1">Akshay</string>
<string name="hero_1_number_of_movies">15</string>
<string name="hero_1_children">2</string>

<string name="hero_2">Ajay</string>
<string name="hero_2_number_of_movies">55</string>
<string name="hero_2_children">2</string>

for (int i=0;i<numberOfchalisas;i++) {
    int heroName = Integer.valueOf("R.string.hero_" + (i + 1));
    int numMoviesDone = Integer.valueOf("hero_"+(i+1)+"_number_of_movies");
    int numChildren = Integer.valueOf("hero_"+(i+1)+"_children");

    String name = getString(heroName);
}
