Add a new custom key value and key processing process under
Android . I'm not afraid of everyone's jokes. The reason why I wrote this blog is that I went to a small company to interview Android system engineers a few days ago, and then the technical director of the other party asked during the interview. I have a question, please describe in detail how to add custom key values under Android and describe in detail the key processing process of Android. Looking back now, the answer at that time was really not very good. I will take advantage of the free time now to analyze the above two questions.
First, analyze how to add a new custom key value under Android. In Android's native system, the key values are 92 by default, ranging from 0-91; under normal circumstances, these key values are sufficient, but if you want to expand, you still need to add new key values, then how to A new key value is mapped from the driver settings to the upper layer, so that the application can handle our custom key value accordingly?
Before introducing how to add new key values in Android, let's introduce the flow of the INPUT subsystem FLOW under Android. The following is a simplified flowchart diagram:
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
[cpp] view plain copy
<span style="font-family:FangSong_GB2312;font-size:18px;">shell@orange:/ # cat /proc/bus/input/devices

By printing the information, we can know that our terminal device uses the Vendor_3697_Product_0001.kl file. I only analyze the IT remote control device here. Then what is in our Vendor_3697_Product_0001.kl? We can view it through the cat command. The specific information is as follows :

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。
In the input system of the framework layer, add the capture of wifi keys.
The added file is: frameworks/base/policy/src/com/android/internal/policy/impl/PhoneWindowManager.java
The specific method added: In the interceptKeyBeforeQueueing() function of PhoneWindowManager.java, do not confuse the key value, as for how to deal with it Execute your business deal too.
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。
Important addition:
Mapping relationship:
The ir hardware scan code is mapped to a key value defined in kernel/include/linux/input.h in the driver. But this key value is only used in linux system.
Android completes the mapping of the linux key value to the key value to be used by the Android system through the device/xxx/xxx.kl ( keylayout ) file in the source directory
