我是android中的rxJava的新手。我已经成功创建了可观察的对象。现在，我想创建flowable。我不太清楚flowable是否以相同的方式工作。以下是我的可观察代码，效果很好。
Observable<String> observable = Observable.create(new ObservableOnSubscribe<String>() {
@Override
public void subscribe(final ObservableEmitter<String> e) throws Exception {
//Use onNext to emit each item in the stream//
t = new Timer();
t.scheduleAtFixedRate(
new TimerTask() {
public void run() {
if (listObj.size() > 0) {
varToBeAddedInObservable = listObj.remove(listObj.size() - 1);
e.onNext(varToBeAddedInObservable);
} else {
e.onComplete();
t.cancel();
}
}
},
0, // run first occurrence immediatetly
1000);
}
}
);
/////////
observable
.subscribeOn(Schedulers.io())
.observeOn(AndroidSchedulers.mainThread())
//.toFlowable(BackpressureStrategy.BUFFER)
.subscribe(myObserver);
//////////////
private Observer<String> getMyObserver() {
return new Observer<String>() {
@Override
public void onSubscribe(Disposable d) {
Log.d(TAG, "onSubscribe");
}
@Override
public void onNext(String s) {
Log.d(TAG, "Name: " + s);
int colorIndex = random.nextInt(arrayColors.length);
//Color color = (arrayColors[colorIndex]);
textView.setTextColor(arrayColors[colorIndex]);
textView.setText(varToBeAddedInObservable);
AlphaAnimation fadeIn = new AlphaAnimation(0.0f, 1.0f);
// AlphaAnimation fadeOut = new AlphaAnimation( 1.0f , 0.0f ) ;
textView.startAnimation(fadeIn);
// textView.startAnimation(fadeOut);
fadeIn.setDuration(1500);
fadeIn.setFillAfter(true);
/* fadeOut.setDuration(1200);
fadeOut.setFillAfter(true);
fadeOut.setStartOffset(1200 - fadeIn.getStartOffset());
fadeOut.setAnimationListener(new Animation.AnimationListener() {
@Override
public void onAnimationStart(Animation animation) {
}
@Override
public void onAnimationEnd(Animation animation) {
textView.setTextColor(Color.BLACK);
textView.setText("Khallas !!!!");
}
@Override
public void onAnimationRepeat(Animation animation) {
}
});*/
}
@Override
public void onError(Throwable e) {
Log.e(TAG, "onError: " + e.getMessage());
}
@Override
public void onComplete() {
Log.d(TAG, "All items are emitted!");
textView.setTextColor(Color.BLACK);
textView.setText("Finished !!!!");
}
};
上面的代码工作正常，现在我正在尝试使用flowable进行相同操作，但是不允许我订阅，那么该怎么做？我读到，需要有一些类似一次性的东西才能订阅可流动货币，但我并没有获得适当的榜样。谢谢：）
private Flowable<String> getMyflowable() {
return new Flowable<String>() {
@Override
protected void subscribeActual(Subscriber<? super String> s) {
}
};
}
