Android传感器各种解释

目前常用的有两种（小三也只有两种）

加速传感器：SENSOR_ACCELEROMETER

姿态传感器：SENSOR_ORIENTATION

经试验

public void onSensorChanged(int sensor, float[] values) {

里的values为如下含义;

当传感器为姿态传感器(SENSOR_ORIENTATION)时values的含义如下：

SENSOR_ORIENTATION, SENSOR_ORIENTATION_RAW:

All values are angles in degrees.

values[0]: Azimuth, rotation around the Z axis (0<=azimuth<360). 0 = North, 90 = East, 180 = South, 270 = West

values[1]: Pitch, rotation around X axis (-180<=pitch<=180), with positive values when the z-axis moves toward the y-axis.

values[2]: Roll, rotation around Y axis (-90<=roll<=90), with positive values when the z-axis moves toward the x-axis.

values[0] 为Yaw轴上的转动角度

values[1] 为Pitch轴上的转动角度

values[2] 为Roll轴上的转动角度

加传感器相应，首先在onCreate里获得系统的sensorsevice

s_sensor = (SensorManager)getSystemService(SENSOR_SERVICE);

之后再Activity类下的onResume里设定监听

int mask = 0; mask |= SensorManager.SENSOR_ORIENTATION;//姿态传感器 //mask |= SensorManager.SENSOR_ACCELEROMETER;//加速度传感器 s_sensor.registerListener(mListener, mask, SensorManager.SENSOR_DELAY_GAME);

然后，在创建监听接口

public static float s_sensorValue[] = new float[3];private final SensorListener mListener = new SensorListener() {@Overridepublic void onAccuracyChanged(int sensor, int accuracy) {// TODO Auto-generated method stub}@Overridepublic void onSensorChanged(int sensor, float[] values) {// TODO Auto-generated method stubif(sensor == SensorManager.SENSOR_ORIENTATION){s_sensorValue[0] = values[0];s_sensorValue[1] = values[1];s_sensorValue[2] = values[2];//System.out.println("value[0] = " + values[0]);//System.out.println("value[1] = " + values[1]);//System.out.println("value[2] = " + values[2]);}} };

之后就可以根据获得的s_sensorValue去进行传感器相应啦。
