关于Android中的传感器

  /*获取手机上所有传感器的信息*/    private void getAllSensor() {        mSensorManager = (SensorManager) getSystemService(Context.SENSOR_SERVICE);        //获取手机上支持的所有传感器        List<Sensor> mList = mSensorManager.getSensorList(Sensor.TYPE_ALL);        for (Sensor sensor : mList) {            Log.e("KeithXiaoY", "名字：" + sensor.getName());            Log.e("KeithXiaoY", "type:" + "(" + sensor.getType() + ")");            Log.e("KeithXiaoY", "vendor:" + sensor.getVendor());            Log.e("KeithXiaoY", "version:" + sensor.getVersion());            Log.e("KeithXiaoY", "resolution:" + sensor.getResolution());            Log.e("KeithXiaoY", "max range:" + sensor.getMaximumRange());            Log.e("KeithXiaoY", "power:" + sensor.getPower());            if (sensor.getType() == 5) {                mSensorManager.registerListener(new SensorEventListener() {                    @Override                    public void onSensorChanged(SensorEvent event) {                        if (event.sensor.getType() == Sensor.TYPE_LIGHT) {                            Toast.makeText(getApplicationContext(), "光线变化", Toast.LENGTH_LONG).show();                        }                    }                    @Override                    public void onAccuracyChanged(Sensor sensor, int accuracy) {                    }                }, sensor, SensorManager.SENSOR_DELAY_FASTEST);//SensorManager.SENSOR_DELAY_FASTEST这个表示最即时的，另外三个，参照SensorManager中的定义            }        }    }
