my.startAccelerometer

Use this JSAPI to start to receive the data from the accelerometer. The current mini program starts to receive the AccelerometerChange event.

Sample Code

copy
// .js
Page({
    listener(res) {
      console.log("1" + JSON.stringify(res))
    },
    listener2(res) {
      console.log("2" + JSON.stringify(res));
    },
    start() {
      my.startAccelerometer({
        success: () => {
          my.onAccelerometerChange(this.listener);
          my.onAccelerometerChange(this.listener2);
        }
      });
    },
    stop() {
      my.stopAccelerometer();
    },
    offSingle() {
      my.offAccelerometerChange(this.listener);
    }
});
