android键值传递

一、kernel/include/linux/input.h

#define KEY_HOME                102

二、kernel/arch/arm/mach-rk30/board-rk30-sdk.c

{

                .desc   = "home",

                .code   = KEY_HOME,

                .adc_value      = 550,

                .gpio = INVALID_GPIO,

                .active_low = PRESS_LEV_LOW,

},

三、device/rockchip/rksdk/rk29-keypad.kl

key 143   NOTIFICATION      WAKE

key 158   BACK

key 186   AVR_POWER

key 212   CAMERA

此处的值与KeycodeLabels.h对应。

四、frameworks/native/include/android/keycodes.h

/*

 * Key codes.

 */

enum {

    AKEYCODE_STB_POWER       = 179,

    AKEYCODE_STB_INPUT       = 180,

    AKEYCODE_AVR_POWER       = 181,

    AKEYCODE_AVR_INPUT       = 182,

五、frameworks/native/include/input/KeycodeLabels.h

    { "TV_INPUT", 178 },

    { "STB_POWER", 179 },

    { "STB_INPUT", 180 },

    { "AVR_POWER", 181 },

    { "AVR_INPUT", 182 },

此处的值与KeyEvent.java对应。

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

        <enum name="KEYCODE_TV_INPUT" value="178" />

        <enum name="KEYCODE_STB_POWER" value="179" />

        <enum name="KEYCODE_STB_INPUT" value="180" />

        <enum name="KEYCODE_AVR_POWER" value="181" />

        <enum name="KEYCODE_AVR_INPUT" value="182" />

七、frameworks/base/core/java/android/view/KeyEvent.java

     * On TV remotes, switches the input mode on an external Set-top-box. */

    public static final int KEYCODE_STB_INPUT       = 180;

    /** Key code constant: A/V Receiver power key.

     * On TV remotes, toggles the power on an external A/V Receiver. */

    public static final int KEYCODE_AVR_POWER       = 181;

    /** Key code constant: A/V Receiver input key.

     * On TV remotes, switches the input mode on an external A/V Receiver. */

    public static final int KEYCODE_AVR_INPUT       = 182;

   修改 LAST_KEYCODE

八、frameworks/native/libs/input/Input.cpp

bool KeyEvent::isSystemKey(int32_t keyCode) {

    switch (keyCode) {

        case AKEYCODE_MENU:

        case AKEYCODE_SOFT_RIGHT:

        case AKEYCODE_HOME:

        case AKEYCODE_BACK:

        case AKEYCODE_CALL:

        case AKEYCODE_ENDCALL:

        case AKEYCODE_VOLUME_UP:

        case AKEYCODE_VOLUME_DOWN:

        case AKEYCODE_VOLUME_MUTE:

        case AKEYCODE_MUTE:
