添加按键F13（内核中已经定义键值为183），在android上层自定义键值映射600，流程如下：

frameworks/base/data/keyboards/Generic.kl

......key 183   F13

frameworks/native/include/input/InputEventLabels.h

static const InputEventLabel KEYCODES[] = {    ......    DEFINE_KEYCODE(F13),    { NULL, 0 }};

frameworks/native/include/android/keycodes.h

enum {    ......    AKEYCODE_F13 = 600,}

frameworks/base/core/res/res/values/attr.xml

<attr>    ......    <enum name="KEYCODE_F13" value="600" /></attr>

frameworks/base/core/java/android/view/KeyEevent.java

public class KeyEvent extends InputEvent implements Parcelable {    ......    public static final int KEYCODE_F13 = 600;     }

frameworks/base/policy/src/com/android/internal/policy/impl/PhoneWindowManager.java

public int interceptKeyBeforeQueueing(KeyEvent event, int policyFlags) {    ......    switch (keyCode) {        case KeyEvent.KEYCODE_F13:{            ......            break;        }    }}
