我们更改了`framework/base/services/input/inputreader.cpp 中的部分代码，以使鼠标右键单击可以返回。

case BTN_RIGHT:
    mBtnRight = rawEvent->value;
    break;

至

case BTN_RIGHT:                       
    mBtnBack = rawEvent->value;
    break;

它正在接收所有鼠标事件。当我单击鼠标右键时，它正在接收运动事件以及按键事件。但它无法调度按键事件。

它给出的错误：

D/InputDispatcher( 1229): dispatchKey - eventTime=1352984476958100000, deviceId=2, source=0x2002, policyFlags=0x42000000, action=0x1, flags=0x0, keyCode=0x4, scanCode=0x0, metaState=0x0, repeatCount=0, downTime=1352984476958100000

Reason: Waiting because the focused window has not finished processing the input events that were previously delivered to it.

它是果冻豆中的错误吗？

要使鼠标 Right_click 用作后退按钮，请执行以下更改。它对我有用。

 in function reset(InputDevice* device) {

            replace mBtnRight = device->isKeyPressed(BTN_RIGHT); line to

                    mBtnBack =  device->isKeyPressed(BTN_RIGHT);

             and 
  in function process(const RawEvent* rawEvent) {

              remove  3 lines   case BTN_RIGHT:
                                mBtnRight = rawEvent->value;
                                break;
                     and Add "case BTN_RIGHT:" before case BTN_BACK:" as shown below

                     case BTN_RIGHT:
                     case BTN_BACK:                       
                     mBtnBack = rawEvent->value;
                     break;

/*这就是它为我工作的全部。*/
