cc.systemEvent.on(cc.SystemEvent.EventType.DEVICEMOTION, this._onDevicemotion, this);
this._onDevicemotion可以触发，event.acc.x和event.acc.y一直都是0

做了测试，没有复现你说的情况

    cc.systemEvent.setAccelerometerEnabled(true);
    cc.systemEvent.on(cc.SystemEvent.EventType.DEVICEMOTION, (evt)=>{
        console.log(evt.acc.x, evt.acc.y);
    })
