获取光传感器值
|
因此，我正在寻找一种方法，只需按下按钮即可获取光传感器的当前值（显然以勒克斯计）。这是我用来实现光传感器控制的代码
public class SensorActivity extends Activity implements SensorEventListener
{
private final SensorManager mSensorManager;
private final Sensor mLight;
int minLux = 0;
int currentLux = 0;
int maxLux;
public SensorActivity()
{
mSensorManager = (SensorManager)getSystemService(SENSOR_SERVICE);
mLight = mSensorManager.getDefaultSensor(Sensor.TYPE_LIGHT);
}
protected void onResume()
{
super.onResume();
mSensorManager.registerListener((SensorEventListener) this, mLight, SensorManager.SENSOR_DELAY_NORMAL);
}
protected void onPause()
{
super.onPause();
mSensorManager.unregisterListener((SensorListener) this);
}
public void onAccuracyChanged(Sensor sensor, int accuracy)
{
if(sensor.getType() == Sensor.TYPE_LIGHT)
{
}
}
public void onSensorChanged(SensorEvent event)
{
if( event.sensor.getType() == Sensor.TYPE_LIGHT)
{
}
}
}
<Button android:layout_width=\"122px\" android:id=\"@+id/widget35\" android:text=\"Start\" android:layout_height=\"wrap_content\" android:layout_x=\"112dp\" android:layout_y=\"249dp\" android:onClick=\"onButtonDown\"></Button>
int maxLux;

public void onSensorChanged(SensorEvent event) { if( event.sensor.getType() == Sensor.TYPE_LIGHT) { currentLux = event.values[0]; if (currentLux > maxLux) maxLux = currentLux; } }
