Android下添加新的自定义键值和按键处理流程
[align=left] 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？[/align]
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：

[align=left] 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[/align]

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
[align=left] key 123 WLS[/align]
[align=left] 说明：[/align]
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" />
[align=left] [/align]
[align=left] 5)在 frameworks/base/core/java/android/view/KeyEvent.java添加对应的[/align]
[align=left] public static final int KEYCODE_WLS = 320;[/align]
[align=left] 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。[/align]
[align=left] [/align]
[align=left] [/align]
[align=left] 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。[/align]
[align=left] [/align]
[align=left] [/align]
[align=left] 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：[/align]
[align=left] 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[/align]
Android下添加新的自定义键值和按键处理流程
[align=left] 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？[/align]
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：
[align=left] 1.添加按键及其映射[/align]
[align=left] 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[/align]

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
[align=left] key 123 WLS[/align]
[align=left] 说明：[/align]
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" />
[align=left] [/align]
[align=left] 5)在 frameworks/base/core/java/android/view/KeyEvent.java添加对应的[/align]
[align=left] public static final int KEYCODE_WLS = 320;[/align]
[align=left] 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。[/align]

[align=left] 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。[/align]
[align=left] [/align]
[align=left] [/align]
[align=left] 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：[/align]
[align=left] 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[/align]
