RxJava - Completable Observable
Completable 类表示延迟响应。Completable 可观察序列可以指示完成成功或错误。
Class Declaration
以下是 io.reactivex.Completable 类的声明 −
public abstract class Completable
extends Object
implements CompletableSourceCompletable Example
在任意编辑器中使用任何您选择的语言（如 C:\>RxJava) 创建以下 Java 程序。
ObservableTester.java
import java.util.concurrent.TimeUnit;
import io.reactivex.Completable;
import io.reactivex.disposables.Disposable;
import io.reactivex.observers.DisposableCompletableObserver;
import io.reactivex.schedulers.Schedulers;
public class ObservableTester {
public static void main(String[] args) throws InterruptedException {
//Create an observer
Disposable disposable = Completable.complete()
.delay(2, TimeUnit.SECONDS, Schedulers.io())
.subscribeWith(new DisposableCompletableObserver() {
@Override
public void onError(Throwable e) {
e.printStackTrace();
}
@Override
public void onStart() {
System.out.println("Started!");
}
@Override
public void onComplete() {
System.out.println("Done!");
}
});
Thread.sleep(3000);
//start observing
disposable.dispose();
}
}
