遥控器键值修改实现新系统全局飞梭
先来说一说安卓键值的知识，没耐心学的可以直接拉倒低看怎么修改：第一步：init.rc：通过service remotecfg /system/bin/remotecfg /system/etc/remote.conf在开机init阶段，将remote.conf中的配置通过ioctl赋值到ir驱动的变量中（用户空间—>内核空间），这样遥控定制化配置才会生效。remotecfg程序代码位于external/remoteconf/irremote.c，可以在设备的/system/bin/下找到它并手动运行#./system/bin/remotecfg /system/etc/remote.conf第二步：红外驱动（Linux内核层）：Linux irremote driver将依照红外驱动配置文件，将红外键值ircode映射为Linux标准键盘扫描码scancode。这个过程即将红外遥控器的按键事件转换为Linux的标准input event。a) 红外驱动配置文件/system/etc/remote.confb)标准键盘扫描码kernel/include/linux/input.h（在几次遥控器定制化中，尚未修改过该文件）第三步：Andriod层：windows manager从irremote driver中读出key event，再通过/system/usr/keylayout/aml_keypad.kl文件，将标准input设备的scan code映射为Andriod API按键KEYCODE字符串。最终scancode和keycode被window manager发送到应用程序，被其focus view消化处理。例如：key 113 SEARCH官方称.kl为key layout map file。映射/配置文件说明ircode映射为scan code： device/a***c/xxx/remote.conf#a***c NEC remotefactory_code = 0xfb040001 //每个设备都有独特的factory code. 格式custom_code(16bit)+index_code(16bit) //例子: 0xfb040001= 0xfb04(客户码) + 0001 (低16位可填写任意值)key_begin //按键映射表 0x47 11 //0x47是红外键值，11是对应的标准按键scancode，可以多个键值对应一个scancode0x5C 97……key_end //按键映射表结束
mouse_begin //鼠标方向映射表，每行0 0x10 //0是方向数字表示符（Left）,对应红外按键键值0x101 0x11 //方向键右2 0x0b //方向键上3 0x0e //方向键下mouse_end //鼠标方向映射表结束
scancode与KEYCODE字符串映射：在2.3系统中，位于源码目录的device/a***c/xxx/ aml_keypad.kl在4.0系统中，位于源码目录的device/a***c/xxx/Vendor_0001_Product_0001.kl
因为酷开系统全是4.0以上安卓，所以我们需要找到一下两个文件：/system/usr/keylayout/Vendor_0001_Product_0001.kl
/system/etc/remote.conf
电视系统ROOT后，用RE找到上述两个文件。用文件编辑器打开；
/remote.conf 文件中内容：

保存后退出，电视断电重启，再试试。完美飞梭实现啦！不要太爽了。老系统请见
强烈支持楼主ing…… 11111111 我只是路过打酱油的。 很给力，ZNDS有你更精彩！ 很给力，ZNDS有你更精彩！ 废话羊肉汤锅 废话羊肉汤锅 嘿嘿,不知有木有用，试试先！！... !gjhg
