Question

我正在研究iphone中的传感器动作，我想知道是否有人知道如何在android中实现启动和停止传感器动作。我搜索了这个论坛，但未能找到确定的东西。有没有人有线索？

Answer 1

在活动中使用传感器很容易。基本上你需要：

1º声明您需要的传感器。

    // Sensor static
static private SensorManager mSensorManager;
static private List<Sensor> deviceSensors;
static private Sensor mAccelerometer;
static private Sensor mGravity;
static private Sensor mGyroscope;
static private Sensor mLinearAcceleration;
static private Sensor mRotationVector;
static private Sensor mOrientation;
static private Sensor mMagneticField;
static private Sensor mProximity;
static private Sensor mPressure;
static private Sensor mLight;

2º您必须初始化所有onCreate，如下所示：

       // Add sensor manager STATIC (only 1 time)
    mSensorManager = (SensorManager) getSystemService(Context.SENSOR_SERVICE);
    deviceSensors = mSensorManager.getSensorList(Sensor.TYPE_ALL);


    // Load default Sensors
    loadDefaultSensors();

    // Set Sensor Listener
    setAllSensorListener();

3ºloadDefaultSensors就是这样：

        mAccelerometer = mSensorManager.getDefaultSensor(Sensor.TYPE_ACCELEROMETER);
    mGravity = mSensorManager.getDefaultSensor(Sensor.TYPE_GRAVITY);
    mGyroscope = mSensorManager.getDefaultSensor(Sensor.TYPE_GYROSCOPE);
    mLinearAcceleration = mSensorManager.getDefaultSensor(Sensor.TYPE_LINEAR_ACCELERATION);
    mRotationVector = mSensorManager.getDefaultSensor(Sensor.TYPE_ROTATION_VECTOR);
    mOrientation = mSensorManager.getDefaultSensor(Sensor.TYPE_ORIENTATION);
    mMagneticField = mSensorManager.getDefaultSensor(Sensor.TYPE_MAGNETIC_FIELD);
    mProximity = mSensorManager.getDefaultSensor(Sensor.TYPE_PROXIMITY);
    mPressure = mSensorManager.getDefaultSensor(Sensor.TYPE_PRESSURE);
    mLight = mSensorManager.getDefaultSensor(Sensor.TYPE_LIGHT);

4，设置听众：

        mSensorManager.registerListener(this, mAccelerometer, SensorManager.SENSOR_DELAY_NORMAL);
    mSensorManager.registerListener(this, mGravity, SensorManager.SENSOR_DELAY_NORMAL);
    mSensorManager.registerListener(this, mGyroscope, SensorManager.SENSOR_DELAY_NORMAL);
    mSensorManager.registerListener(this, mLinearAcceleration, SensorManager.SENSOR_DELAY_NORMAL);
    mSensorManager.registerListener(this, mRotationVector, SensorManager.SENSOR_DELAY_NORMAL);
    mSensorManager.registerListener(this, mOrientation, SensorManager.SENSOR_DELAY_NORMAL);
    mSensorManager.registerListener(this, mMagneticField, SensorManager.SENSOR_DELAY_NORMAL);
    mSensorManager.registerListener(this, mProximity, SensorManager.SENSOR_DELAY_NORMAL);
    mSensorManager.registerListener(this, mPressure, SensorManager.SENSOR_DELAY_NORMAL);
    mSensorManager.registerListener(this, mLight, SensorManager.SENSOR_DELAY_NORMAL);

5º如果需要保存CPU等，可以使用unlistener onPause并再次注册onResume

        mSensorManager.unregisterListener(this);
