당신은 그것을 이름으로 생성 된 자원을 런타임에 접근 할 수 있습니다

String direction = "nn"; 
String fullName = "wind_direction" + direction; 

// Get the identifier of the resource by its name. 
@StringRes int resId = getResources().getIdentifier(fullName, "string", getPackageName()); 
// Use the value of the resource. 
String message = getString(resId);
