如何在计步器应用程序中检测用户活动状态？

如何解决如何在计步器应用程序中检测用户活动状态？

build.gradle：实现'com.google.android.gms:play-services-location:18.0.0'

我想知道用户的活动状态。 但是，仅测量“_ENTER”值。未测量值“_EXIT”。

此外，“event.getElaspsedREalTimeNanos”时间值的测量也很奇怪。 => 93498488000000 这实际上不是手机检测到活动的时间吗？ 我做错了什么？

SimpleDateFormat format_base = new SimpleDateFormat("yyy-MM-dd HH:mm");

@Override

    testContext = context;
    String type = intent.getAction();


    if (ActivityTransitionResult.hasResult(intent)) {
        ActivityTransitionResult result = ActivityTransitionResult.extractResult(intent);
        for (ActivityTransitionEvent event : result.getTransitionEvents()) {
            int getActivityType = event.getActivityType();
            int getTransitionType = event.getTransitionType();

            String user_state;

            switch (getActivityType) {
                case 0:
                    user_state = "IN_VEHICLE";
                    break;

                case 1:
                    user_state = "ON_BICYCLE";
                    break;

                case 2:
                    user_state = "ON_FOOT";
                    break;

                case 3:

                    break;

                case 7:

                default:
                    user_state = "error";
                    break;
            } // .. switch


            if (getTransitionType == 0) {
                user_state += "_ENTER";
            } else if (getTransitionType == 1) {
                user_state += "_EXIT";
            } else {
                // none
            }

            Date date = new Date(event.getElapsedRealTimeNanos());
            MainActivity.mainActivity.text_sample.append(format_base.format(date) + " = " + user_state + "\n");
