在Nexus One上光线感应器只返回两个不同的值 [英] Light sensor on Nexus One returns only two distinct values

问题描述

I'm尝试读取我的Nexus One的光传感器的值，但I'mgetting只有以下值：

I´m trying to read the values of the Light Sensor of my Nexus One, but I´mgetting only following values:

10.0

225.0

和在一些情况下一些值要高得多。

and in a few cases some values much higher.

在使用code：

sensorManager = (SensorManager) context
                .getSystemService(Context.SENSOR_SERVICE);
        sensor = sensorManager.getDefaultSensor(Sensor.TYPE_LIGHT);

        listener = new SensorEventListener() {

            @Override
            public void onAccuracyChanged(Sensor sensor, int accuracy) {
            }

            @Override
            public void onSensorChanged(SensorEvent event) {
                 Log.d(Constants.TAG, "Brightness: " + event.values[0]);

            }

        };
        sensorManager.registerListener(listener, sensor,
                SensorManager.SENSOR_DELAY_NORMAL);

    }

没有任何人有在Nexus One上或其他Android设备的光传感器的经验？ 是C阅读价值的正确方法我$ C $？ 我怎样才能得到更好，更准确的价值？

Does anybody have experience with the light sensor on the Nexus One or another Android device? Is my code the correct way to read the values? How can I get better and more accurate values?

推荐答案

您code看起来不错。我收到的值是这样的：10，225，320，640，1280，2600，3200，10240，但我真的需要点设备朝着太阳获得更高的价值。

Your code looks fine. I was receiving values like this: 10, 225, 320, 640, 1280, 2600, 3200, 10240. But I really needed to point device towards sun to receive higher values.

编辑：从可以在手机上使用Android的API来获得光传感器的特性 - 10240是一个可以由该传感器返回的最高值

from light sensor characteristic that can be obtained on my phone by using Android API - 10240 is the highest value that can be returned by this sensor.
