Using Sensor for Android phones is similar to WeChat shake

There are several types of sensors:
Direction sensor: sensor. type_orientation
Acceleration (gravity) sensor: sensor. type_accelerometer
Light Sensor: sensor. type_light
Magnetic Field Sensor: sensor. type_magnetic_field
Distance (proximity) sensor: sensor. type_proximity
Temperature Sensor: sensor. type_temperature

 

Here we use the acceleration sensor.

ABS (Values [0])> 17 | math. ABS (Values [1])> 17 | math. ABS (Values [2])> 17) {log. D ("sensor", "============= values [0] =" + values [0]); log. D ("sensor", "============= values [1] =" + values [1]); log. D ("sensor", "============= values [2] = "+ Values [2]); TV. settext (" Shake "); // After shaking the mobile phone, it will be accompanied by a vibration prompt ~~ Vibrator. vibrate (500 );}}}}

Remember to switch the sensor listening event during onresume and onpause.

If you want to adjust the sensitivity of the sensor, modify it. The value [0, 1, 2] is greater than the upper limit.
