声明：这里只是做个笔记，如有高见，请多指教！

现在的android手机多是触屏的，对实体按键的支持仅限home，menu，volumeup，volumedown，power等常用的几个，如果想支持类似功能机的全键盘，方向键等，可以修改以下文件，

1，修改 ：frameworks/base/core/res/res/values/Config.xml文件

<bool name="config\_hasPermanentDpad">false</bool>

把这个值改为true，表明现在是有方向键行为的。

2，修改：frameworks/base/core/java/android/content/res/Configuation.java

/\*\*  
\* Set this object to the system defaults.  
\*/  
public void setToDefaults() \{

...

navigation = NAVIGATION\_UNDEFINED;

把默认的导航设置为：navigation = NAVIGATION\_DPAD;

...

3，根据 \\frameworks\\base\\data\\keyboards\\Generic.kl 这个按键映射表，

配置当前项目的按键布局

\\android\\device\\qcom\\msm8909\\gpio-keys.kl

附录：Generic.kl 按键映射表

\\android\\frameworks\\base\\data\\keyboards\\Generic.kl

\\android\\frameworks\\base\\data\\keyboards\\qwerty.kl
