在WMS::PhoneWindowManager::interceptKeyBeforeQueueing中监听上下左右左右键进行拦截。
Overridepublic long interceptKeyBeforeDispatching(WindowState win, KeyEvent event, int policyFlags) {//是否开启鼠标模式String mstate SystemProperties.get(sys.KeyMouse.mKeyMouseState);//是否开启鼠标滚轮模式String mMode SystemProperties.get(sys.mouse.mousemode1);if (mstate.equals(on) ((keyCode KeyEvent.KEYCODE_DPAD_LEFT)|| (keyCode KeyEvent.KEYCODE_DPAD_RIGHT)|| (keyCode KeyEvent.KEYCODE_DPAD_UP)|| (keyCode KeyEvent.KEYCODE_DPAD_DOWN))) {if(down){if (mMode.equals(false)) {try{// 显示鼠标键mWindowManager.dispatchMouse(0,0);}catch(Exception e){}} else {Message msg new Message();msg.what keyCode;Bundle bundle new Bundle();bundle.putInt(repeatCount, repeatCount);msg.setData(bundle);mKeyMouseHandler.sendMessage(msg);}}return -1;}

2.调整鼠标滚动逻辑 如果只需要鼠标上下移动上述修改即可鼠标移动到屏幕周围会自动切为滚动模式但是如果部分app上下有部分导航栏即需要主动将鼠标切为滚轮模式。 修改位置 frameworks/native/services/inputflinger/InputReader.cpp
