Android: Tracking mouse pointer movement

问题

Assuming that I am using a generic mouse, is it possible to track the X and Y coordinates of the mouse pointer in android?

回答1:

You need a OnGenericMotionListener:

OnGenericMotion(...., MotionEvent me) {
if (me.getToolType(0) == MotionEvent.TOOL_TYPE_MOUSE) {

}

api 14+ needed [confirmed] Found me a tablet with usb mouse and can confirm this works for mouse movement. You WILL get flooded with messages, so simple operations or sleeping should be considered.

回答2:

The docs to ACTION_MOVE lead me to think that only drag events would be reported:

Constant for getAction(): A change has happened during a press gesture (between ACTION_DOWN and ACTION_UP). The motion contains the most recent point, as well as any intermediate points since the last down or move event.

In my case the OnGenericMotion solution did not work but attaching an OnHoverListener to the main view did the trick.
