Remarks
Resolve the pointer icon that should be used for specified pointer in the motion event.
The default implementation will resolve the pointer icon to one set using #setPointerIcon(PointerIcon) for mouse devices. Subclasses may override this to customize the icon for the given pointer.
For example, the pointer icon for a stylus pointer can be resolved in the following way: <pre> @Override public PointerIcon onResolvePointerIcon(MotionEvent event, int pointerIndex) { final int toolType = event.getToolType(pointerIndex); if (!event.isFromSource(InputDevice.SOURCE_MOUSE) && event.isFromSource(InputDevice.SOURCE_STYLUS) && (toolType == MotionEvent.TOOL_TYPE_STYLUS || toolType == MotionEvent.TOOL_TYPE_ERASER)) { // Show this pointer icon only if this pointer is a stylus. return PointerIcon.getSystemIcon(mContext, PointerIcon.TYPE_WAIT); } // Use the default logic for determining the pointer icon for other non-stylus pointers, // like for the mouse cursor. return super.onResolvePointerIcon(event, pointerIndex); } </pre>
