本文介绍了如何使用计时器重新开始录制视频每preset的间隔时间？的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
有人能告诉我如何可以使用像一个计时器开始视频记录间隔过程中一段时间（例如：5分钟），然后重新启动录制另一组5分钟的视频，直到用户干预，制止过程。 。我在安卓/ JAVA kinna新，因此有人可以帮助我一起这个问题？

Can someone tell me how can i use something like a timer to start a video recording interval process for a period of time (eg: 5mins) then restarts to record another set of 5min video until the user intervene to stop the process.. I'm kinna new in android/java so can someone help me along with this question?

mediaRecorder = new MediaRecorder();

public void stopRecording() {

解决方案
This will start and stop the recording every 5 minutes,
final ServiceRecording recording = ....
final AtomicBoolean started = new AtomicBoolean(false);
ScheduledExecutorService executor = Executors.newScheduledExecutor(1);
executor.scheduleAtFixedRate(new Runnable() {
public void run() {
//only stop if we have started
if(started.get()) {
recording.stop();
} else {
started.set(true);
}
recording.start();
}
}, 5, 5, TimeUnit.MINUTES);
