Android下添加新的自定義鍵值和按鍵處理流程
說出來不怕大家笑話，我寫這篇博客的原因在于前幾天去一個小公司面試Android系統工程師，然后在面試的時候對方的技術總監問了我一個問題，請你詳細描述一下怎么在Android下添加自定義鍵值和詳細描述下Android的按鍵處理流程。現在回想起來當時回答的確實不是很好，乘著現在比較空閑的時機就來分析下上述的兩個問題。
??? 首先分析下Android下怎么添加新的自定義鍵值。在Android的原生系統中鍵值默認情況下是92個，從0-91；一般情況下，這些鍵值是夠用的，但是如果想擴充的話，還是需要添加新的鍵值的，那么如何將一個新的鍵值從驅動的設置映射到上層，使應用可以對我們自定義的鍵值進行相應的處理呢？ 在介紹Android怎么添加新的鍵值以前先介紹下Android下INPUT子系統FLOW的流程，下面就是精簡的流程圖示意圖：
1.添加按鍵及其映射 1)如果系統有新的按鍵需要添加，瑪門是怎么添加并上報到系統上層去的呢(這里的上層主要指的是Android應用層)，首先要確定的是我們的遙控設備是通過/dev/input目錄下那個event調用那個kl文件，這里可以通過如下命令超看cat /proc/bus/input/devices,下面是在終端下的打印信息

2)在Vendor_3697_Product_0001.kl文件中添加映射 key 123 WLS 說明： key?-- 是關鍵字。固定值，不需要改變。
? ? ?123?-- 該按鍵在linux驅動中對應的鍵值，我在這里只是假設的這個值，至于具體對應的是那個可以查看“include/linux/input.h”
? ? ?WLS?-- 123按鍵映射到Android中的按鍵，它對應是“KeycodeLabels.h”文件中的KEYCODES表格元素的“literal”值。
? ? ? ? 其中KeycodeLabels.h的定義如下，我們可以在"MSTAR_PVR_BROWSER", 319后面添加我們需要向Android上層拋的鍵值，我們這里定義為"WLS", 320,所以當Android上層監聽到320的按鍵值是就是我們新添加的鍵值了。

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添加對應的 public static final int KEYCODE_WLS = 320; 經過如上的步驟就將"123"按鍵和Android系統中的KEYCODE_WLS就對應起來了，注意這里的"123“鍵值并不是真正意義上的123鍵值，他只是linux驅動向上層拋出的鍵值。
6)在Android的framework層的鍵值處理函數中，捕獲按鍵，并進行相應處理。
在framework層的input系統中，加入對wifi按鍵的捕獲。
添加的文件是：frameworks/base/policy/src/com/android/internal/policy/impl/PhoneWindowManager.java
添加的具體方法：在PhoneWindowManager.java的interceptKeyBeforeQueueing()函數中,不惑該鍵值，至于怎么處理處決您的業務處理了。 在這里再總結下我對Android鍵值處理的理解，我的理解：看了一下key character map的處理，是通過讀取kl文件然后使用驅動程序提供的ioctl函數去修改來自輸入設備的掃描碼和系統預定義的keycode的映射關系。 這樣的話，對于硬件掃描碼，只需要修改這個kl文件。上層得到的都是系統預定義的keycode。
重要補充：
映射關系： ir硬件掃描碼在驅動里面被 映射為 kernel/include/linux/input.h里面定義的某個鍵值。但是這個鍵值只在linux系統中使用。
Android通過源碼目錄下的device/xxx/xxx.kl( keylayout )文件完成linux鍵值到Android系統要使用的鍵值的映射
