下面参考附图对本技术的实施例进行详细描述。
图 1示出了本技术的一个实施例提供的处理滑动事件的方法的实现流程, 详述如下。
步骤 S101中, 检测滑动事件。
在一个实施例 中 , 经由本领域中 已知的缩放手势侦听器 ( ScaleGestureDetector )检测滑动事件, 所述滑动事件为一个或多个手指在 触摸屏上按下后滑动的触摸事件。 例如, 该缩放手势侦听器 ScaleGestureDetector 可 以 是 类 安 卓 . 视 图 . 缩 放 手 势 侦 听 器 ( android.view.ScaleGestureDetector ), 该类既述 口下:
根据接收的动作事件 ( MotionEvent ) , 检测由多个触点 ( "多点触控" ) 引发的变形手势。 回调缩放手势侦听器, OnScaleGestureListener的回调函数 会在特定手势事件发生时通知用户。 该类仅能和触控事件引发的动作事件 ( MotionEvent ) 配合使用, 使用该类需要:
( 1 ) 为视图创建缩放手势侦听器(ScaleGestureDetector )并初始化; ( 2 )保证在函数 onTouchEvent(MotionEvent)方法中调用了该类的函数 onTouchEvent(MotionEvent)方法, 事件发生时执行用户所定义的回调函数。
当然, 检测滑动事件的手段不限于此, 并且可以采用本领域中已知的其 他检测方法。
步骤 S102中, 计算所述滑动事件涉及的指头数, 若所述滑动事件涉及的 指头数为二以上(包括二,下文同 ),则将所述滑动事件标识为多指滑动事件。
在一个实施例中, 根据检测的信号, 例如根据缩放手势侦听器 ( ScaleGestureDetector )发送过来的信号, 计算所述滑动事件涉及的指头数, 若所述滑动事件涉及的指头数为二以上, 则将所述滑动事件标识为多指滑动 事件。
例如, 如果所述滑动事件涉及的指头数为二, 则可以将所述多指滑动事 件标识为双指滑动事件; 若所述滑动事件涉及的指头数为三, 则可以将所述 滑动事件标识为三指滑动事件; 若所述滑动事件涉及的指头数为四, 则可以 将所述滑动事件标识为四指滑动事件。 例如, 参与所述双指滑动事件的手指 可以是食指和中指, 也可以是食指和无名指等等。
步骤 S103中, 判断所述多指滑动事件中各手指的移动方向是否一致, 如 果一致, 则触发使图片移动的编辑手势。
在一个实施例中, 判断所述多指滑动事件中涉及的各手指的移动方向是 否一致, 若一致, 则由所述多指滑动事件触发使图片移动的编辑功能。
在图 2中, 示出了通过多指滑动事件触发移动图片的编辑功能的一个例 子。 尽管图 2中示出由移动方向一致的双指的滑动而触发图片的移动, 但是, 触发图片移动功能的滑动事件不限于双指操作, 也可以是三指、 四指、 甚至 五指操作。
在一个实施例中, 可以由双指中心点偏移的距离确定图片移动的距离。 例如, 在通过食指与中指进行滑动的情况下, 若这两个手指移动方向一致, 则可以由该两指的中心点偏移的距离来确定图片移动的距离。 如此即可根据 滑动事件涉及的手指的个数及各手指的移动方向, 判断是否移动图片, 无需 切换功能按钮, 操作筒单、 方便。
另外, 若所述双指滑动事件中各手指的移动方向不一致, 则可以由所述 双指滑动事件触发使图片缩放的编辑功能。
若所述滑动事件涉及的指头数为一, 则可以将所述滑动事件标识为单指 滑动事件, 并可以触发涂抹图片的编辑功能。
例如, 图 3示出了通过单指滑动事件触发涂抹图片的编辑功能的一个例 子, 其中用户可于触摸屏上用单指对图片进行涂抹操作。 若要移动图片, 则 可以用双指或更多手指按住图片并往同一方向滑动, 即可移动图片, 如图 2 所示。 此时无需切换移动和涂抹编辑功能按钮, 操作筒单、 方便。
在另一实施例中, 单指滑动事件也可以触发剪裁图片等的编辑功能。 同 样地, 用户在利用单指操作进行剪裁图片的功能时, 可以利用多指滑动事件 在同一方向上的移动来触发移动图片的功能。
图 4示出了本技术的一个实施例提供的处理滑动事件的系统的框图,详述 :¾口下。
根据此实施例的处理滑动事件的系统可以包括: 检测单元 401、 计算标识 单元 402以及判断触发单元 403。 其中, 所述检测单元 401可以用于检测滑动事 件, 所述滑动事件为一个或多个手指在触摸屏上按下后滑动的触摸事件。 所 述计算标识单元 402可以用于计算所述滑动事件涉及的指头数,若所述滑动事 件涉及的指头数为二以上, 则将所述滑动事件标识为多指滑动事件。 所述判 断触发单元 403可以用于判断所述多指滑动事件中各手指的移动方向是否一 致, 若一致, 则触发使图片移动的编辑功能。
可选地, 该系统还可以包括确定单元(未示出), 用于如果所述滑动事件 涉及的指头数为二,则可以通过双指中心点偏移的距离确定图片移动的距离。
所述判断触发单元还可以用于如果所述滑动事件涉及的指头数为二, 并 且如果所述滑动事件中各手指的移动方向不一致, 则触发使图片缩放的编辑 功能。
作为例子, 根据本技术的上述系统可以应用于具有触摸屏显示器的移动 终端。 当然, 本技术的应用不限于此。 应当说明的是, 上述各单元具体工作原理如前文所述, 此处不再加以赘 述。 另外, 上述处理滑动事件的系统的各个单元可以为软件单元、 硬件单元 或者软硬件结合的单元, 软件单元部分可以存储于一计算机可读取存储介质 中, 如 ROM/RAM、 磁盘、 光盘等。
