Rxjava 小序

Rxjava

1、异步处理

2、功能使用

以下demo：每隔一秒更新随机数字

---

a、onResume()

 updataInfo = new Subscriber<Long>() {
        @Override
        public void onCompleted() {
        }
        @Override
        public void onError(Throwable e) {
        }
        @Override
        public void onNext(Long number) {
            ULog.e("HandlerActivity","实时更新中..........."+number);
            String result = "实时更新中，当前大盘指数：<font color='green'>%d</font>";
            result = String.format(result, (int) (Math.random() * 3000 + 1000));
            tv_content2.setText(Html.fromHtml(result));
        }
    };

 Observable.interval(0,1,TimeUnit.SECONDS).subscribeOn(Schedulers.io())
            .unsubscribeOn(Schedulers.io())
            .observeOn(AndroidSchedulers.mainThread()).subscribe(updataInfo);

b、取消订阅

protected void onPause() {
    super.onPause();
    if(!updataInfo.isUnsubscribed())
      updataInfo.unsubscribe();
}
