Advanced Article-Android system: 4. Android mobile phone action sensor

Motion sensors are useful for monitoring the movement of devices, such as tilt, vibration, rotation, and swing, which are the monitoring ranges of motion sensors. The movement of a device is usually a direct response to user input.All motion sensors return a value of three floating-point numbers, and for different sensors, the three values have different meanings. For example, for an accelerometer, the acceleration data for three axes is returned. For a gyroscope

Android uses a direction sensor to obtain the relative angle of the mobile phone. Example description:

1. How does the android coordinate system define the x and y z axes? The X axis direction is from left to right along the horizontal direction of the screen. If the mobile phone is not a square, the shorter side needs to be placed horizontally, and the longer side needs to be placed vertically. The Y-axis direction is from the lower left corner of the screen along the vertical direction of the screen to the top of the screen.Place the mobile phone o
