Infinite Auto Scroll ListView with Scroll Speed Controlled

Question

I have been working on a ListViewidea where it keeps scrolling automatically with no user interaction and that is absolutely doable using the android APIs for i

Answer 1

I suggest, thath your adapter implemented in effective way. so this code is just scrolls listview

you need to try another values of variables

final long totalScrollTime = Long.MAX_VALUE; //total scroll time. I think that 300 000 000 years is close enouth to infinity. if not enought you can restart timer in onFinish()

final int scrollPeriod = 20; // every 20 ms scoll will happened. smaller values for smoother

final int heightToScroll = 20; // will be scrolled to 20 px every time. smaller values for smoother scrolling

listView.post(new Runnable() {
                        @Override
                        public void run() {
                                new CountDownTimer(totalScrollTime, scrollPeriod ) {
                                    public void onTick(long millisUntilFinished) {
                                        listView.scrollBy(0, heightToScroll);
                                    }

                                public void onFinish() {
                                    //you can add code for restarting timer here
                                }
                            }.start();
                        }
                    });
