Android中的字符串资源是否可以使用“复合标识符”？

Question

字符串资源是否可以使用“化合物标识符”？ 像这样

val level = 1      <- current level
getString(R.string.answer + level)    <- and this is get (R.string.answer1) string

有可能吗？

Answer 1

利用Resources.getIdentifier(String, String, String)方法动态生成所需的资源ID，然后使用该生成的ID正常调用getString(int)。

例如

int level = 1;
String name = "answer" + level;
int stringResId = getResources().getIdentifier(name, "string", getPackageName());

String result = getString(stringResId);
