该问题是在这里：

  @Override
  protected void onResume() {
    super.onResume();
    // register this class as a listener for the orientation and
    // accelerometer sensors
    sensorManager.registerListener(this, sensorManager.getDefaultSensor(Sensor.TYPE_ACCELEROMETER),SensorManager.SENSOR_DELAY_NORMAL);
  }

  @Override
  protected void onPause() {
    // unregister listener
    // sensorManager.unregisterListener(this);
  }

你不注销侦听器，使其注册多次。

You're not unregistering the listener, so it is registered multiple times.

我知道你想要做的是继续听即使该活动被暂停，而你的可能的使用布尔标志，只能注册一次。但它可能不是一个好主意。 Activites不可见可以由系统在任何时候结束。

I understand that what you want to do is to keep listening even if the activity is paused, and you could use a boolean flag to only register once. But it's probably not a good idea. Activites that are not visible can be finished by the system at any time.

有关这些类型的用例服务将更为合适的（作为奖励，你可以将它设置为启动对 BOOT_COMPLETED ，这样你就不需要重新运行应用程序，当你重新启动设备设置此监听器）。

For these kinds of use cases a Service would be far more appropriate (as a bonus, you could set it up to start on BOOT_COMPLETED, so that you don't need to re-run the app to set up this listener when you restart the device).

所以，总之，我会建议：

So, in short, I would recommend:

• 创建服务。在的onCreate（），注册服务作为一个监听器的SensorManager （非常多，你在这里做的）。


• 当你的活动运行，发送意图来启动服务（见的文档）。


• （可选），从而使服务重新启动设备重新启动时，指定ACTION_BOOT_COMPLETED的监听器。请参见这个答案。

• Create a Service. In onCreate(), register the service as a listener to SensorManager (very much as you do here).
• When your activity runs, send an Intent to start the service (see docs).
• Optionally, specify a listener for ACTION_BOOT_COMPLETED so that the service is restarted when the device restarts. See this answer.
