- 在\frameworks\base\services\input\InputReader.cpp文件下修改
- uint32_t CursorButtonAccumulator::getButtonState() const {
- uint32_t result = 0;
- if (mBtnLeft) {
- result |= AMOTION_EVENT_BUTTON_PRIMARY;
- }
- if (mBtnRight) {
- result |= AMOTION_EVENT_BUTTON_BACK;
- }
- if (mBtnMiddle) {
- result |= AMOTION_EVENT_BUTTON_TERTIARY;
- }
- if (mBtnBack || mBtnSide) {
- result |= AMOTION_EVENT_BUTTON_BACK;
- }
- if (mBtnForward || mBtnExtra) {
- result |= AMOTION_EVENT_BUTTON_FORWARD;
- }
- return result;
注意:这个cpp文件是可执行的,通过vi和gedit都不能成功修改,所以要么先将权限去掉(猜想),要么使用vim修改
