1、map(）操作符（一对一的转化）
Observable.just("Hello") .map(new Func1<String, String>() { @Override public String call(String s) { return s + "rxjava"; } }).subscribe(new Action1<String>() { @Override public void call(String s) { Log.d("s", s); } });lambda表达式
Observable .just("hello") .map(s -> s+"rxjava") .subscribe(s -> Log.d("s",s));2、flapMap()：一对多
Student[] students = ...;Subscriber<Course> subscriber = new Subscriber<Course>() { @Override public void onNext(Course course) { Log.d(tag, course.getName()); } ...};Observable.from(students) .flatMap(new Func1<Student, Observable<Course>>() { @Override public Observable<Course> call(Student student) { return Observable.from(student.getCourses()); } }) .subscribe(subscriber);新闻热点
