瑞芯微平台
SDK：Android4.4
好久没写博客了，最近工作中需要在SDK中添加一个新的遥控器支持，由于自己对java代码比较头大，过程也是一波三折，整个流程其实分析下来并不难，这里做个简单的总结。也算是学习android的一个开端。
1. 遥控器红外键值到linux层的映射
安卓4.4后linux层和红外层的键值映射是在设备树中修改的，不需要在linux中修改驱动代码，直接在相应的dts文件中修改即可，首先每个遥控器都有一个usercode,按照瑞芯微方面提供的文档：
在终端中输入命令：echo 1 > sys/module/cmcc_pwm_remotectl/parameters/code_print
其中USERCODE=0xf601的遥控器用户码，用来标识是哪一个遥控器，RMC_GETDATA=bb，这个是遥控器设备linux驱动中对应的按键上报的对应的键值。
文件目录\kernel\arch\arm\boot\dts\xxx.dts
在代码中先添加如下框架（文件里面照葫芦画瓢）（先把usercode这样加上，然后输入上面的命令才能记录相应按键DTS中对应的值）：
我这上面是修改好的样子，0xbb和0xbc分别对应的是向上键和确定键。这些都是记录的键值，
<0xbc
KEY_REPLY>, 其中0xbc在DTS文件中确定键对应的宏定义 KEY_REPLY这个要在input.h文件中去找
input.h文件路径：kernel\arch\arm\boot\dts\include\dt-bindings\input\input.h
DTS文件中每一按键的键值都可以通过打印来记录，每一个键值所对应的宏可以通过linux驱动层中input.h文件中对应的宏找到。名字一定要保持一致！其中上面确定键对应的232是linux层上报android层的键值。
就这样记录所有的按键，然后在DTS文件对号入座，第一步遥控器红外层到linux层的键值映射就搞定了
2. Linux层到android层的键值映射
同样通过终端输入命令：getevent 记录Linux层到android层的键值记录
对应的映射文件就是110b0030_pwm.kl 这个是可以在相关配置文件修改确定是哪个KL文件是linux层到android层键值映射，也可以修改为自己创建的KL文件。
文件目录：盒子根文件目录下的/system/usr/keylayout/110b0030_pwm.kl文件
这里232是确定键从Linux层上报到android层的键值，其中确定键对应的宏DPAD_CENTER 这个可以在keyevent.java文件中找到
一般的遥控器常规按键做到这两步了,基本都没问题了，但是特殊按键的添加还需要继续完善！
通常Linux驱动层基本不需要修改，第一步：我们只需要修改对应的KL文件即可。
已遥控器上的搜索按键为例：
由于DTS文件中：
<0xa7
KEY_PROGRAM> a7是记录的搜索键的键值， 后边对应的宏是input.h文件中可以找到对应的，这个加进去就好了
KL文件中：
key 362 TV_SEARCH //362是getevent命令记录的搜索键的键值， TV_SEARCH是自定义的宏，这个名字自己可以随便定义。
第二个修改的地方是keycodes.h文件
文件目录：frameworks\native\include\android\keycodes.h
在文件中添加一个没有用到的键值
第三个修改的地方是KeycodeLables.h文件
文件目录：\frameworks\native\include\input\KeycodeLables.h
第四个修改attrs.xml文件
文件目录：\frameworks\base\core\res\res\values\arrrs.xml
第五个修改的文件：KeyEvent.java （这个文件修改的地方有两个）
如果添加的是最后一个别忘了LAST_KEYCODE 这个要和最后一个保持一致.下面还有一个地方也要添加：
至此特殊按键搜索按键从红键值外层到android层的键值映射就完成了。搜索按键到android应用层的键值映射就是257.
特殊按键应用层特殊处理可以修改PhoneWindowManager.java文件
文件目录：\frameworks\base\policy\src\com\android\internal\policy\impl\PhoneWindowManager.java
特殊按键处理这次应用层的做法是修改PhoneWindowManager.java文件，同时在上面的目录中添加keyfunction.java文件。
