Android下添加新的自定义键值和按键处理流程

    说出来不怕大家笑话,我写这篇博客的原因在于前几天去一个小公司面试Android系统工程师,然后在面试的时候对方的技术总监问了我一个问题,请你详细描述一下怎么在Android下添加自定义键值和详细描述下Android的按键处理流程。现在回想起来当时回答的确实不是很好,乘着现在比较空闲的时机就来分析下上述的两个问题。
    首先分析下Android下怎么添加新的自定义键值。在Android的原生系统中键值默认情况下是92个,从0-91;一般情况下,这些键值是够用的,但是如果想扩充的话,还是需要添加新的键值的,那么如何将一个新的键值从驱动的设置映射到上层,使应用可以对我们自定义的键值进行相应的处理呢?
    在介绍Android怎么添加新的键值以前先介绍下Android下INPUT子系统FLOW的流程,下面就是精简的流程图示意图:Android下添加新的自定义键值和按键处理流程【转】

    1.添加按键及其映射
    1)如果系统有新的按键需要添加,玛门是怎么添加并上报到系统上层去的呢(这里的上层主要指的是Android应用层),首先要确定的是我们的遥控设备是通过/dev/input目录下那个event调用那个kl文件,这里可以通过如下命令超看cat /proc/bus/input/devices,下面是在终端下的打印信息
  1. <span style="font-family:FangSong_GB2312;font-size:18px;">shell@orange:/ # cat /proc/bus/input/devices
  2. I: Bus=0018 Vendor=3697 Product=0001 Version=0001
  3. N: Name="MStar Smart TV IR Receiver"
  4. P: Phys=/dev/ir
  5. S: Sysfs=/devices/virtual/rc/rc0/input0
  6. U: Uniq=
  7. H: Handlers=kbd event0
  8. B: PROP=0
  9. B: EV=13
  10. B: KEY=fc0000 0 fc900 142851 0 0 0 0 108000 1a8 c0000c01 9e37c0 48007 f8000000 10000ffc
  11. B: MSC=10
  12. I: Bus=0000 Vendor=0000 Product=0000 Version=0000
  13. N: Name="MCE IR Keyboard/Mouse (ir)"
  14. P: Phys=/input0
  15. S: Sysfs=/devices/virtual/input/input1
  16. U: Uniq=
  17. H: Handlers=kbd mouse0 event1
  18. B: PROP=0
  19. B: EV=100017
  20. B: KEY=30000 0 7 ff87207a c14057ff febeffdf ffefffff ffffffff fffffffe
  21. B: REL=3
  22. B: MSC=10
  23. shell@orange:/ #
  24. shell@orange:/ # </span>
 

通过打印信息我们可以知道,我们的终端设备使用的是Vendor_3697_Product_0001.kl文件,我这里只分析IT遥控设备,那我们的Vendor_3697_Product_0001.kl里面又是啥呢,我们可以通过cat命令查看,具体的信息如下:

2)在Vendor_3697_Product_0001.kl文件中添加映射

       key 123 WLS
       说明:
       key -- 是关键字。固定值,不需要改变。
     123 -- 该按键在linux驱动中对应的键值,我在这里只是假设的这个值,至于具体对应的是那个可以查看“include/linux/input.h”
     WLS -- 123按键映射到Android中的按键,它对应是“KeycodeLabels.h”文件中的KEYCODES表格元素的“literal”值。
        其中KeycodeLabels.h的定义如下,我们可以在"MSTAR_PVR_BROWSER", 319后面添加我们需要向Android上层抛的键值,我们这里定义为"WLS", 320,所以当Android上层监听到320的按键值是就是我们新添加的键值了。

4)在frameworks/base/core/res/res/values/attrs.xml添加如下
         <enum name="KEYCODE_WLS" value="320" />

 
     5)在 frameworks/base/core/java/android/view/KeyEvent.java添加对应的
        public static final int KEYCODE_WLS = 320;
     经过如上的步骤就将"123"按键和Android系统中的KEYCODE_WLS就对应起来了,注意这里的"123“键值并不是真正意义上的123键值,他只是linux驱动向上层抛出的键值。
 
 
     6)在Android的framework层的键值处理函数中,捕获按键,并进行相应处理。
在framework层的input系统中,加入对wifi按键的捕获。
添加的文件是:frameworks/base/policy/src/com/android/internal/policy/impl/PhoneWindowManager.java
添加的具体方法:在PhoneWindowManager.java的interceptKeyBeforeQueueing()函数中,不惑该键值,至于怎么处理处决您的业务处理了。
 
 
       在这里再总结下我对Android键值处理的理解,我的理解:看了一下key character map的处理,是通过读取kl文件然后使用驱动程序提供的ioctl函数去修改来自输入设备的扫描码和系统预定义的keycode的映射关系。 这样的话,对于硬件扫描码,只需要修改这个kl文件。上层得到的都是系统预定义的keycode。
重要补充:
  映射关系:
    ir硬件扫描码在驱动里面被 映射为 kernel/include/linux/input.h里面定义的某个键值。但是这个键值只在linux系统中使用。
  Android通过源码目录下的device/xxx/xxx.kl( keylayout )文件完成linux键值到Android系统要使用的键值的映射
