传感器有几种类型：
方向传感器： Sensor.TYPE_ORIENTATION
加速度(重力)传感器： Sensor.TYPE_ACCELEROMETER
光线传感器: Sensor.TYPE_LIGHT
磁场传感器： Sensor.TYPE_MAGNETIC_FIELD
距离(临近性)传感器： Sensor.TYPE_PROXIMITY
温度传感器： Sensor.TYPE_TEMPERATURE
这里我们利用的是加速度传感器

super.onResume();
sensorManager.registerListener(this, sensorManager.getDefaultSensor(Sensor.TYPE_ACCELEROMETER), SensorManager.SENSOR_DELAY_NORMAL);
}
@Override
public void onAccuracyChanged(Sensor sensor, int accuracy) {
//当传感器精度改变时回调该方法，Do nothing.
}
@Override
public void onSensorChanged(SensorEvent event) {
int sensorType = event.sensor.getType();
//values[0]:X轴，values[1]：Y轴，values[2]：Z轴
float[] values = event.values;
if(sensorType == Sensor.TYPE_ACCELEROMETER){
if((Math.abs(values[0])>17||Math.abs(values[1])>17||Math.abs(values[2])>17)){
Log.d("sensor ", "============ values[0] = " + values[0]);
Log.d("sensor ", "============ values[1] = " + values[1]);
Log.d("sensor ", "============ values[2] = " + values[2]);
tv.setText("摇一摇");
//摇动
手机后，再伴随震动提示~~
vibrator.vibrate(500);
}
}
}
}
记得在onresume和onpause的时候开关sensor的监听事件。
如果想调整sensor的敏感程度，就去修改，value[0,1,2] 大于的上限。
