前言
前段时间有做一个客户修改了遥控器的按键排布，需要修改键值按键的功能，主要是修改framework层的按键上层处理，此篇做一个记录。
文件修改
总共需要修改下列文件
- device/mstar/S2/preinstall/keylayout/Vendor_0000_Product_0000.kl
- include/linux/input.h
- kitkat-mstar-master/device/mstar/S2/preinstall/modules/rc-mstar-tv.ko
- kitkat-mstar-master/frameworks/base/api/current.txt
- kitkat-mstar-master/frameworks/base/core/java/android/view/KeyEvent.java
- kitkat-mstar-master/frameworks/base/core/res/res/values/attrs.xml
- kitkat-mstar-master/frameworks/base/policy/src/com/android/internal/policy/impl/PhoneWindowManager.java
- kitkat-mstar-master/frameworks/native/include/android/keycodes.h
- kitkat-mstar-master/frameworks/native/include/input/KeycodeLabels.h
修改步骤
一、确定按键键值是否有上报：
使用串口输入getevent 命令：
/dev/input/event1: 0004 0000 0000029f
/dev/input/event1: 0004 0001 0000007a
/dev/input/event1: 0004 0002 fff0fc86
/dev/input/event1: 0004 0004 000001ac
/dev/input/event1: 0004 0007 f71c02a7
/dev/input/event1: 0000 0000 00000000
/dev/input/event1: 0004 0000 00002307
/dev/input/event1: 0004 0001 fffffc6d
/dev/input/event1: 0004 0002 fff12e53
/dev/input/event1: 0004 0004 000001ac
/dev/input/event1: 0004 0007 fc7a5385
/dev/input/event1: 0000 0000 00000000
/dev/input/event7: 0004 0004 00000035
/dev/input/event7: 0000 0000 00000000
/dev/input/event1: 0004 0000 00002a2d
当我们按下按键的时候会上报event7事件，接着输入：getevent dev/input/event7
测试我们需要修改的遥控器按键，按下按键，出现如下类似的内容说明有按键上报，说明底层驱动是已经适配好了，只需要修改上层就好了。
0004 0004 00000035
0000 0000 00000000
0004 0004 000000fc
0000 0000 00000000
0004 0004 00000018
二、确定KL键值映射文件
android kl（key layout）文件是一个映射文件，是标准linux与anroid的键值映射文件，kl文件可以有很多个，但是它有一个使用优先级，一般代码中的kl文件都是在device下面，我们需要找到代码中使用的kl文件是哪个
输入：cat /proc/bus/input/devices

根据前面得到的input时间，比如前面得到的是input7事件，那么我们要找的kl文件就是Vendor_0000_Product_0000.kl
