Android4.1添加新的按键(3)

添加新的物理按键 DECT_REGISTER, DECT_PHONE

1.kl文件添加按键码映射，251，252 是 驱动上报上来的键值

key 251 DECT_REGISTER

key 252 DECT_PHONE

2.frameworks/base/include/androidfw/KeycodeLabels.h

对KEYCODES，添加按键码

static const KeycodeLabel KEYCODES[] = {

...

{ "DECT_REGISTER",220},

{ "DECT_PHONE",221},

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

<enum name="KEYCODE_DECT_REGISTER" value="220"/>

<enum name="KEYCODE_DECT_PHONE" value="221"/>

4.frameworks/native/include/android/keycode.h

enum {

AKEYCODE_UNKNOWN = 0,

....

....

添加

AKEYCODE_DECT_REGISTER =220,

AKEYCODE_DECT_PHONE =221,

5.frameworks/base/core/java/android/view/KeyEvent.java

添加

public static final int KEYCODE_DECT_REGISTER= 220;

public static final int KEYCODE_DECT_PHONE=221;

修改 LAST_KEYCODE 和 KEYCODE_SYMBOLIC_NAMES

private static final int LAST_KEYCODE = KEYCODE_DECT_REGISTER;

// NOTE: If you add a new keycode here you must also add it to:

// isSystem()

// native/include/android/keycodes.h

// frameworks/base/include/ui/KeycodeLabels.h

// external/webkit/WebKit/android/plugins/ANPKeyCodes.h

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

// emulator?

// LAST_KEYCODE

// KEYCODE_SYMBOLIC_NAMES

private static void populateKeycodeSymbolicNames() {

SparseArray<String> names = KEYCODE_SYMBOLIC_NAMES;

names.append(KEYCODE_UNKNOWN, "KEYCODE_UNKNOWN");

...

...

names.append(KEYCODE_DECT_REGISTER, "KEYCODE_DECT_REGISTER");

names.append(KEYCODE_DECT_PHONE, "KEYCODE_DECT_PHONE");

}

修改 isSystem(),追踪jni需要修改frameworks/base/lib/androidrw/input.cpp KeyEvent::isSystemKey

bool KeyEvent::isSystemKey(int32_t keyCode) {

switch (keyCode) {

....

case AKEYCODE_DECT_REGISTER:

case AKEYCODE_DECT_PHONE:

return true;

}

return false;

}

6.external/webkit/Source/WebKit/android/plugins/ANPKeyCodes.h

修改

enum ANPKeyCodes {

kUnknown_ANPKeyCode = 0,

...

...

kDectRegister_ANPKeyCode=220,

kDectPhone_ANPKeyCode=221,

}

以上修改完成后，可以在PhoneWindowManager 测试下这个两个键是否成功上报，如果上报成功，就可以在自己的应用中添加与这个按键相关的逻辑处理。
