Question

我制作了这个代码，我在教程中找到并进行了一些更改。该代码显示了方向和加速计传感器，当智能手机改变45°时，它会计算曲线的数量。它完美地运作。但我看到SENSOR_ORIENTATION，SENSOR_ACCELEROMETER已被弃用。如何使用非弃用的常量更改我的代码并使其保持工作？我是android编程和堆栈溢出的初学者。谢谢！

每当您想要引用传感器时，请使用：Sensor.TYPE_XXXX。例如：Sensor.TYPE_ACCELEROMETER＆amp; Sensor.TYPE_ORIENTATION。

我不知道是否需要它，但你可能想检查是否＆＃34; sm＆＃34; onResume（）中为null。此外，您可能希望在onPause（）而不是onStop（）中取消注册SensorEventListener。

如何将SENSOR_ORIENTATION更改为未弃用的代码并运行此代码
