核心代码片段如下：private Handler handler = new Handler(){ public void handleMessage(Message msg) { switch (msg.what) { case SHAKE_START: isShake = true;//摇动中 startAnimation(); break; case SHAKE_END://摇动结束 isShake = false; stopAnimation(); Toast.makeText(TestSensorActivity1.this, "检测到摇晃，执行你想要的操作！", Toast.LENGTH_SHORT).show(); break; default: break; } super.handleMessage(msg); } }; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.yaoyiyao_test1_layout); sensorManager = (SensorManager) getSystemService(SENSOR_SERVICE); vibrator = (Vibrator) getSystemService(Service.VIBRATOR_SERVICE); animation_yaoyiyao= (ImageView) findViewById(R.id.yaoyiyao_test1_img); } @Override protected void onResume() { super.onResume(); // 注册监听器 sensorManager.registerListener(this, sensorManager.getDefaultSensor(Sensor.TYPE_ACCELEROMETER), SensorManager.SENSOR_DELAY_NORMAL); } @Override protected void onPause() { super.onPause(); sensorManager.unregisterListener(this); } @Override public void onSensorChanged(SensorEvent sensorEvent) { int sensorType = sensorEvent.sensor.getType(); // values[0]:X轴，values[1]：Y轴，values[2]：Z轴 float[] values = sensorEvent.values; Log.e("YaoYiYao", "values[0]:" + values[0] + " values[1]:" + values[0] + " values[2]" + values[0]); if (sensorType == Sensor.TYPE_ACCELEROMETER) { if ((Math.abs(values[0]) + Math.abs(values[1])+ Math .abs(values[2])) > 18) { // 摇动手机后，再伴随震动提示~~ if(!isShake){ vibrator.vibrate(new long[]{200, 300, 200, 300, 200}, -1); //发送一个空消息，告诉handler已经开始摇动了 handler.sendEmptyMessage(SHAKE_START); //间隔1.2s,发送一个空消息，告诉handler已经结束摇动了//避免了多次请求处理 handler.sendEmptyMessageDelayed(SHAKE_END, 1200); } } } } @Override public void onAccuracyChanged(Sensor sensor, int i) { // 当传感器精度改变时回调该方法，Do nothing. }
