在android的状态栏(statusbar)中增加menu，home和back快捷键的方法

IWindowManager wm = IWindowManager.Stub.asInterface(ServiceManager.getService("window"));

Log.d("Tiger", "Intent.ACTION_SOFT_"+keyCode+"_PRESSED 2="+(System.currentTimeMillis()/*-n*/));

wm.injectKeyEvent(down, false);

Log.d("Tiger", "Intent.ACTION_SOFT_"+keyCode+"_PRESSED 3="+(System.currentTimeMillis()/*-n*/));

wm.injectKeyEvent(up, false);

Log.d("Tiger", "Intent.ACTION_SOFT_"+keyCode+"_PRESSED 4="+(System.currentTimeMillis()/*-n*/));

} catch (RemoteException e) {

Log.i("Input", "DeadOjbectException");

}

}

};

5.避免在按下这几个按钮时，触发下拉Notification视图，影响性能

修改onInterceptTouchEvent(MotionEvent event)函数

@Override

public boolean onInterceptTouchEvent(MotionEvent event) {

/* Begin : Modified by TigerPan */

if (keysLayout.getRight() < event.getX())

return mService.interceptTouchEvent(event) ? true : super.onInterceptTouchEvent(event);

/*int parentLeft = mStatusIcons.getLeft();

android.util.Log.i("Tiger","....."+(event.getX() < (parentLeft + iconVolDown.getLeft()) || event.getX() > (parentLeft + iconHome.getRight())));

if(event.getX() < (parentLeft + iconVolDown.getLeft()) || event.getX() > (parentLeft + iconHome.getRight()))

return mService.interceptTouchEvent(event) ? true : super.onInterceptTouchEvent(event);

*/

return false;

/* End : Modified by TigerPan */

}

这样，基本上就完成了。
