传感器共有的一些API
sensorManager.registerListener 最后一个参数的值
方法里已经有详细的注释
/** get sensor data as fast as possible */
public static final int SENSOR_DELAY_FASTEST = 0;
/** rate suitable for games */
public static final int SENSOR_DELAY_GAME = 1;
/** rate suitable for the user interface */
public static final int SENSOR_DELAY_UI = 2;
/** rate (default) suitable for screen orientation changes */
public static final int SENSOR_DELAY_NORMAL = 3;
onAccuracyChanged方法回调的参数
/**
* The values returned by this sensor cannot be trusted because the sensor
* had no contact with what it was measuring (for example, the heart rate
* monitor is not in contact with the user).
*/
public static final int SENSOR_STATUS_NO_CONTACT = -1;
/**
* The values returned by this sensor cannot be trusted, calibration is
* needed or the environment doesn't allow readings
*/
public static final int SENSOR_STATUS_UNRELIABLE = 0;
/**
* This sensor is reporting data with low accuracy, calibration with the
* environment is needed
*/
public static final int SENSOR_STATUS_ACCURACY_LOW = 1;
/**
* This sensor is reporting data with an average level of accuracy,
* calibration with the environment may improve the readings
*/
public static final int SENSOR_STATUS_ACCURACY_MEDIUM = 2;
/** This sensor is reporting data with maximum accuracy */
public static final int SENSOR_STATUS_ACCURACY_HIGH = 3;
