我认为不可能将两个事件聚合为一个 oob。但使用 OnTouchListener 您绑定到两个按钮的父元素。
当引发事件并调用 onTouch() 方法时。你得到了一堆与事件相关的参数，比如它是什么类型的事件（Action_Down、Action_Move、Action_Up 等）。如果该操作是由第二根手指执行的，您还会获得信息，因此您可以选择决定是否触摸了两个按钮。
在这里你可以找到一个很好的教程关于 Android 上的多点触控支持。
I don't think that it is possible to aggregate two events to a single one oob. But it shouldn't be to hard to determine if two buttons were pressed simultaneously by using a OnTouchListener you bind to the parent element of the two buttons.
When an event is thrown and the onTouch() method is called. You got a bunch of arguments related to the event, like what kind of event it was (Action_Down, Action_Move, Action_Up etc.). You also get the information if the action was performed by the first oder by the second finger so this should give you the option to decide whether both buttons were touched.
Here you can find a nice tutorial about multi touch support on Android.
