LockScreen时MENU键

升级到2.3.7后，发现在启动后，LockScreen状态下，按MENU键不像2.2中那样可以解锁屏幕了。

原来，是被overlay了。

在device/samsung/smdkv210/overlay/frameworks/base/core/res/res/values/config.xml中

    <!-- disable menu hard key on Crespo in non-pattern lockscreen -->

    <bool name="config_disableMenuKeyInLockScreen">true</bool>

搜索

jeff@translogic-desktop:jeff-2.3.7_r1$ grep "config_disableMenuKeyInLockScreen" frameworks/base/ -r --include=*.java 

frameworks/base/policy/src/com/android/internal/policy/impl/LockScreen.java:        final boolean configDisabled = res.getBoolean(R.bool.config_disableMenuKeyInLockScreen);

jeff@translogic-desktop:jeff-2.3.7_r1$ 

LockScreen.java中：

private static final String ENABLE_MENU_KEY_FILE = "/data/local/enable_menu_key";

    private boolean shouldEnableMenuKey() {

        final Resources res = getResources();

        final boolean configDisabled = res.getBoolean(R.bool.config_disableMenuKeyInLockScreen);

        final boolean isMonkey = SystemProperties.getBoolean("ro.monkey", false);

        final boolean fileOverride = (new File(ENABLE_MENU_KEY_FILE)).exists();

        return !configDisabled || isMonkey || fileOverride;

    }

所以，要使MENU可解锁，可以有3种方式：

1.设置config_disableMenuKeyInLockScreen为false

2.设置属性ro.monkey为true，不过还是小心点

3.新建一个文件 /data/local/enable_menu_key
