1、基础知识：A. SensorEventListener传感器事件监听

Overview--------------------------------------------------------------------------------Used for receiving notifications from the SensorManager when sensor values have changed. Summary--------------------------------------------------------------------------------Public Methods abstract void onAccuracyChanged(Sensor sensor, int accuracy) Called when the accuracy of the registered sensor has changed. abstract void onSensorChanged(SensorEvent event) Called when sensor values have changed.

B. OnKeyListener键盘监听

Overview--------------------------------------------------------------------------------Interface definition for a callback to be invoked when a hardware key event is dispatched to this view. The callback will be invoked before the key event is given to the view. This is only useful for hardware keyboards; a software input method has no obligation to trigger this listener. Summary--------------------------------------------------------------------------------Public Methods abstract boolean onKey(View v, int keyCode, KeyEvent event) Called when a hardware key is dispatched to a view.

C. OnTouchListener触摸监听

Overview--------------------------------------------------------------------------------Interface definition for a callback to be invoked when a touch event is dispatched to this view. The callback will be invoked before the touch event is given to the view. Summary--------------------------------------------------------------------------------Public Methods abstract boolean onTouch(View v, MotionEvent event) Called when a touch event is dispatched to a view.
