说到传感器，我们比较熟悉的就是手机的重力传感器，光线传感器。因为我们很多感应手机旋转，打电话时靠近耳朵屏幕熄灭，这些都是传感器的功劳。今天我就介绍一下Android中传感器的种类，并说明如何获取当前手机支持的传感器。
1.Android中传感器的种类
| 编号 | Sensor类的传感器类型 | 传感器名称 | 说明 |
| 1 | TYPE_ACCELEROMETER | 加速度 | 常用于摇一摇功能 |
| 2 | TYPE_MAGNETIC_FIELD | 磁场 | |
| 3 | TYPE_ORIENTATION | 方向 | 已弃用，取而代之的是getOrientation方法 |
| 4 | TYPE_GYROSCOPE | 陀螺仪 | 用来感应手机的旋转和倾斜 |
| 5 | TYPE_LIGHT | 光线 | 用来感应手机正面的光线强弱 |
| 6 | TYPE_PRESSURE | 压力 | 用来感应气压 |
| 7 | TYPE_TEMPERATURE | 温度 | 已弃用，取而代之的是类型13 |
| 8 | TYPE_PROXIMITY | 距离 | |
| 9 | TYPE_GRAVITY | 重力 | |
| 10 | TYPE_LINEAR_ACCELERATION | 线性加速度 | |
| 11 | TYPE_ROTATION_VECTOR | 旋转矢量 | |
| 12 | TYPE_RELATIVE_HUMIDITY | 相对湿度 | |
| 13 | TYPE_AMBIENT_TEMPERATURE | 环境温度 | |
| 14 | TYPE_MAGNETIC_FIELD_UNCALIBRATED | 无标定磁场 | |
| 15 | TYPE_GAME_ROTATION_VECTOR | 无标定旋转矢量 | |
| 16 | TYPE_GYROSCOPE_UNCALIBRATED | 未校准陀螺仪 | |
| 17 | TYPE_SIGNIFICANT_MOTION | 特殊动作 | |
| 18 | TYPE_STEP_DETECTOR | 步行检测 | 用户每走一步就触发一次事件 |
| 19 | TYPE_STEP_COUNTER | 步行计数 | 记录激活后的步伐数 |
| 20 | TYPE_GEOMAGNETIC_ROTATION_VECTOR | 地磁旋转矢量 | |
| 21 | TYPE_HEART_RATE | 心跳速率 | 可穿戴设备使用，如手环 |
| 22 | TYPE_TILT_DETECTOR | 倾斜检测 | |
| 23 | TYPE_WAKE_GESTURE | 唤醒手势 | |
| 24 | TYPE_GLANCE_GESTURE | 掠过手势 | |
| 25 | TYPE_PICK_UP_GESTURE | 拾起手势 |
2.获取当前手机全部传感器类型示例
