我的课程中有一个变量,我希望当变量发生变化时,我会在另一个类中执行操作.事实上我想要一个监听器来改变android中的变量(我的变量可能每分钟都在变化)

public class Connect { 
     public static boolean myBoolean;
//some actions do and myBoolean change   
}

public class Selection extends Activity implements OnMenuItemClickListener{

//I want a thing like listener here ,when myboolean changed I do an action (myboolean may change every minute)

}
