传感器

1.实现SensorEventListener接口

public class MainActivity extends AppCompatActivity implements SensorEventListener{
}

2.activity中执行

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        initView();
        //获取对象
        manager = (SensorManager) getSystemService(SENSOR_SERVICE);
        List sensorList = manager.getSensorList(Sensor.TYPE_ALL);
        //log中打印所有传感器
        for (int i = 0; i < sensorList.size(); i++) {
            Sensor sensor = sensorList.get(i);
            Log.e(TAG, "onCreate: " + sensor.getName());
        }
    }

    @Override
    protected void onStop() {
        super.onStop();
        //取消注册
        manager.unregisterListener(this);
    }

    @Override
    protected void onStart() {
        super.onStart();
        //  在start中注册传感器
        //加速度传感器
        manager.registerListener(this, manager.getDefaultSensor(Sensor.TYPE_ACCELEROMETER),
                SensorManager.SENSOR_DELAY_NORMAL);
        //光感传感器
        manager.registerListener(this, manager.getDefaultSensor(Sensor.TYPE_LIGHT),
                SensorManager.SENSOR_DELAY_NORMAL);
        //方向传感器
        manager.registerListener(this, manager.getDefaultSensor(Sensor.TYPE_ORIENTATION),
                SensorManager.SENSOR_DELAY_NORMAL);

    }

    @Override
    public void onSensorChanged(SensorEvent event) {
        Sensor sensor = event.sensor;
        if (sensor.getType() == Sensor.TYPE_ACCELEROMETER) {
            float x = event.values[0];
            float y = event.values[1];
            float z = event.values[2];
            txt_x1.setText("x轴加速度" + x);
            txt_y1.setText("y轴加速度" + y);
            txt_z1.setText("z轴加速度" + z);
            //摇一摇如果满足产生震动
            if (Math.abs(x) > 15 || Math.abs(y) > 15 || Math.abs(z) > 15) {
                share();
            }
        } else if (sensor.getType() == Sensor.TYPE_LIGHT) {
            float value = event.values[0];
            light.setText("光线强度："+value);
        } else if (sensor.getType() == Sensor.TYPE_ORIENTATION) {
            float z = event.values[0];
            float x = event.values[1];
            float y = event.values[2];
            txt_z2.setText("绕z轴转过的角度:"+z);
            txt_y2.setText("绕x轴转过的角度:"+y);
            txt_x2.setText("绕y轴转过的角度:"+x);
        }

    private void share() {
        //带有声音
        MediaPlayer mediaPlayer = MediaPlayer.create(this, R.raw.weichat_audio);
        mediaPlayer.start();

        vibrator = (Vibrator) getSystemService(VIBRATOR_SERVICE);
        //设置循环奇数为震动时间
        long[] patter = {1000, 2000, 2000, 1000};
        不为-1时一直震动
        vibrator.vibrate(patter, -1);
    }

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

    }
