android– 如果某些条件遇到陀螺仪阅读,如何获得时间

概述当陀螺仪读数x=0.0,y=0.0,z=0.0&时,我希望将时间存储为“dateString”.当x>0.0&&y>0.0&&z>0.0将时间存储为“dateString1”.如果条件得到满足,我无法计时,因为它占用了我手机的当前时间.它一直在运行,因此无法在事件发生时获得时间解决方案是什么？示例–如果我的手

当陀螺仪读数x = 0.0,y = 0.0,z = 0.0&时,我希望将时间存储为“dateString”.当x> 0.0&& y> 0.0&& z> 0.0将时间存储为“dateString1”.
如果条件得到满足,我无法计时,因为它占用了我手机的当前时间.它一直在运行,因此无法在事件发生时获得时间解决方案是什么？

示例 – 如果我的手机处于静止状态,陀螺仪传感器将提供x = 0.0,y = 0.0,z = 0.0如果读数在三小时内仍然相同.假设这是手机睡眠的开始时间.当读数会在x,y,z方面突然改变时,它将是唤醒时间.

如何检测这种情况(睡眠的开始时间和唤醒时间)？

下面的代码是检测陀螺仪读数x,y,z,它仍然分别显示0.0,0.0,0.0.

当pic,x,y,z的电话值增加时,我们如何添加代码来检测时间,如上所述.

注意：请不要告诉Timestamp是我已经尝试过的解决方案.

解决方法:

在SensorEventListener中,您可以使用回调参数SensorEvent事件来使用以下代码获取时间戳,

long timeStamp = event.timestamp;

注意：event.timestamp将返回long.

编辑：根据您的评论更新答案.

要检查设备是否移动超过三个小时,请使用以下代码.

初始化long lastTimeStamp = 0;在您班级的全局变量中.

SensorEventListener sensorEventListener = new SensorEventListener() {            @OverrIDe            public voID onSensorChanged(SensorEvent event) {                float x = event.values[0];                float y = event.values[1];                float z = event.values[2];                if(Math.round(x) == 0 && Math.round(y) == 0 && Math.round(z) == 0) {                    //device dIDn't move - store current timestamp                    lastTimeStamp = event.timestamp;                } else {                    //below if condition is to check if device hasn't been IDle                     if (lastTimeStamp == 0) {                        return;                    }                    //(3 * 60 * 60 * 1000) checks if device wasn't moved for more than 3 hours                    if ((event.timestamp - lastTimeStamp) > (3 * 60 * 60 * 1000)) {                        //code goes here                     }                    lastTimeStamp = 0;                }            }            @OverrIDe            public voID onAccuracyChanged(Sensor sensor, int accuracy) {            }        };

希望这会更清晰.
