1.获取手机的传感(相当于计步器)：
mSensorManager = (SensorManager) getSystemService(SENSOR_SERVICE);2.调用手机中的震动；在换图的时候可以很好的提醒：
mVibrator = (Vibrator) getSystemService(Service.VIBRATOR_SERVICE);3.给震动做监听(当震动响起的时候换图)；又叫传感器事件监听SensorEventListener实现两个方法，在改变中做处理：
private class sensorListener implements SensorEventListener { @Override public void onSensorChanged(SensorEvent event) { int sensorType = event.sensor.getType(); float[] values = event.values; if (sensorType == Sensor.TYPE_ACCELEROMETER) { if ((Math.abs(values[0]) > 12 || Math.abs(values[1]) > 12 || Math .abs(values[2]) > 12)) { flag++; if (flag > 5) flag = 0; long[] pattern = { 500, 500 }; mVibrator.vibrate(pattern, -1); mHandler.sendEmptyMessage(0);//发送消息，提醒换图！ } } }4.在线程中用handler来改变震动换图：
Handler mHandler = new Handler(){ @Override public void handleMessage(Message msg) { super.handleMessage(msg); Resources resources = getResources(); switch (flag){ case 0: mChange.setBackgroundDrawable(resources.getDrawable(R.drawable.pic06)); break; case 1: mChange.setBackgroundDrawable(resources.getDrawable(R.drawable.pic01)); break; case 2: mChange.setBackgroundDrawable(resources.getDrawable(R.drawable.pic02)); break; case 3: mChange.setBackgroundDrawable(resources.getDrawable(R.drawable.pic03)); break; case 4: mChange.setBackgroundDrawable(resources.getDrawable(R.drawable.pic04)); break; case 5: mChange.setBackgroundDrawable(resources.getDrawable(R.drawable.pic05)); break; } } };
