android 注册 sensor 代码

头文件

import android.hardware.Sensor;
import android.hardware.SensorEvent;
import android.hardware.SensorEventListener;
import android.hardware.SensorManager;

监听对象

SensorEventListener mAccListener = new SensorEventListener() {
    @Override
    public void onSensorChanged(SensorEvent event) {
        //Log.d(TAG, "onSensorChanged: event.values[0]" + event.values[0] + " ,event.values[1]" + event.values[1]);
    }

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

定义sensor

private static final String TAG = "AccSensor";
private SensorManager sensorManager;
private Sensor acc_sensor;
private Sensor gyro_sensor;

初始化（加速度sensor）

sensorManager = (SensorManager) getSystemService(Context.SENSOR_SERVICE);
acc_sensor = sensorManager.getDefaultSensor(Sensor.TYPE_ACCELEROMETER);

注册及取消注册

sensorManager.registerListener(mAccListener, acc_sensor, SensorManager.SENSOR_DELAY_NORMAL);
sensorManager.unregisterListener(mAccListener);

SensorManager.SENSOR_DELAY_NORMAL 为调用频率
