动态取得R文件的int值，通过string-array name属性动态获取R.array.xxx的int值

复制代码 代码如下:
//通过string-array name属性动态获取R.array.xxx的int值
public CharSequence[] getListData(String name) {
try {
Class<?> arrayClass = getArrayResource().getClass();
Field intField = arrayClass.getField(name);
int sourceId = intField.getInt(name);
return getResources().getTextArray(sourceId);
} catch (Exception e) {
e.printStackTrace();
}
return null;
}

private Object arrayResource = null;

private Object getArrayResource() {
if (arrayResource == null) {
Class<?> resource = R.class;
try {
Class<?>[] classes = resource.getClasses();
for (Class<?> c : classes) {
int i = c.getModifiers();
String className = c.getName();
String s = Modifier.toString(i);
if (s.contains("static") && className.contains("array")) {
return c.getConstructor().newInstance();
} else {
continue;
}
}
} catch (Exception e) {
e.printStackTrace();
}
}
return arrayResource;
}
