我正在尝试从＆＃34;断开连接＆＃34;复制示例代码。第here节。
断开
正如我们在connect的签名中看到的那样，此方法返回订阅，就像Observable.subscribe一样。您可以使用该引用来终止ConnectableObservable的订阅。这将阻止事件传播给观察者，但它不会取消订阅ConnectableObservable。 如果再次调用connect，ConnectableObservable将启动新订阅，旧观察者将再次开始接收值。
ConnectableObservable<Long> connectable = Observable.interval(200, TimeUnit.MILLISECONDS).publish();
Subscription s = connectable.connect();
connectable.subscribe(i -> System.out.println(i));
Thread.sleep(1000);
System.out.println("Closing connection");
s.unsubscribe();
Thread.sleep(1000);
System.out.println("Reconnecting");
s = connectable.connect();
输出
0
1
2
3
4
Closing connection
Reconnecting
0
1
2
...
使用RxJava 2.0.8，我有：
ConnectableObservable<Long> connectable = Observable.interval(200, TimeUnit.MILLISECONDS).publish();
Disposable s = connectable.connect();
connectable.subscribe(new Observer<Long>() {
@Override
public void onSubscribe(Disposable d) {
}
@Override
public void onNext(Long aLong) {
Log.d("test", "Num: " + aLong);
}
@Override
public void onError(Throwable e) {
}
@Override
public void onComplete() {
}
});
try {
Thread.sleep(1000);
} catch (InterruptedException e) {
e.printStackTrace();
}
Log.d("test", "Closing connection");
s.dispose();
try {
Thread.sleep(1000);
} catch (InterruptedException e) {
e.printStackTrace();
}
Log.d("test", "Reconnecting...");
connectable.connect();
输出
Num: 0
Num: 1
Num: 2
Num: 3
Num: 4
Closing connection
Reconnecting...
