The android accelerometer is of the sensor. type_accelerometer type. Return the value of the accelerometer through Android. Hardware. sensorevent. The Unit returned by the accelerometer is the unit of acceleration m/s ^ 2 (meter per second). The values in three directions are Values [0]: X-axis Acceleration Values [1]: acceleration in Y-axis direction Values [2]: acceleration in the z-axis direction The X, Y, and Z directions are defined as the c
Add a handler function when gravity changesThe function dosomething (x, y, z) that is called when the listener is created is a method that is defined by itself.The listener calls this method when the phone's tilt direction changes.All we have to do is populate the method to do our own processing when gravity changes.When x=y=0, the phone is placed in a horizontal position.When X=0 and Y>0, the top of the phone's horizontal position is greater than the bottom, that is, the general answer to the p

Sensor Type Sensors are an important indicator of the second generation of smartphones. It can be said that Android phones and tablets (excluding TV) on the market now have built-in sensors. Otherwise, many games and applications cannot be used. Not every Android device supports all sensors. Most Android devices only support some sensors. For example, direction sensors (Electronic Compass), gravity sensors (screen flip, racing games, etc ). Motion
