Android光线传感器无法正常检测光线

Question

在尝试为Android应用程序执行光传感器时遇到了一些问题。这是我的代码：

@Override
protected void onCreate(Bundle savedInstanceState) {
sensorManager = (SensorManager) getSystemService(Context.SENSOR_SERVICE);
    Sensor lightSensor = sensorManager.getDefaultSensor(Sensor.TYPE_LIGHT);

    if (lightSensor == null) {
        Toast.makeText(MainActivity.this, "No Light Sensor Found! ",
                Toast.LENGTH_LONG).show();
    } else {
        float max = lightSensor.getMaximumRange();
        sensorManager.registerListener(this, lightSensor,
                SensorManager.SENSOR_DELAY_NORMAL);
    }}

protected void onResume() {
    super.onResume();
    // register this class as a listener for the lightSensor
    sensorManager.registerListener(this,
            sensorManager.getDefaultSensor(Sensor.TYPE_LIGHT),
            SensorManager.SENSOR_DELAY_NORMAL);
}

@Override
protected void onPause() {
    // unregister listener
    super.onPause();
    sensorManager.unregisterListener(this);
}

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

}

// called when sensor value have changed
@Override
public void onSensorChanged(SensorEvent event) {
    // The light sensor returns a single value.
    // Many sensors return 3 values, one for each axis.
    if (event.sensor.getType() == Sensor.TYPE_LIGHT) {
        float currentLight = event.values[0];
        if (currentLight < 1) {
            tVCurrentLight.setText("No Light");
        } else if (currentLight < 5) {
            tVCurrentLight.setText("Dim:"
                    + String.valueOf(currentLight));
        } else if (currentLight < 10) {
            tVCurrentLight.setText("Normal:"
                    + String.valueOf(currentLight));
        } else if (currentLight < 100) {
            tVCurrentLight.setText("Bright(Room):"
                    + String.valueOf(currentLight));
        } else
            tVCurrentLight.setText("Bright(Sun):"
                    + String.valueOf(currentLight));
    }
}

我遇到的问题是它只能检测到两种状态，即明亮（房间）：10.0 和明亮（太阳）：100.0 。有没有办法解决它，以便它可以显示所有5状态取决于环境？

我在当前光源上打印了一个日志，当我只是放入一个房间时，用手覆盖scren时我得到的结果只有10.0而得到的结果是100.0。任何想法为什么它没有得到其他价值观？ 提前谢谢。
