android对多物理按键，方向键的支持

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

   
    false

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
