关于keyboardlayout与locale的对应关系

Question

不同国家，键盘布局不用，其具体的布局是kcm文件中配置的
在\frameworks\base\packages\InputDevices\res\raw下已经有对应的kcm文件，\frameworks\base\packages\InputDevices\res\xml\keyboard_layouts.xml中是这些kcm文件的列表，在framework/base/services/core/java/android/server/input/InputManagerServices.java中已经有去解析keyboard_layouts.xml这个文件，按照InputManagerServices.java ->visitKeyboardLayoutsInPackage这个方法以及 getDefaultKeyboardLayout方法中的实现keyboard_layouts.xml应该要有locale可以与systemLocale匹配的，但实际实现中却没有。肯定知道locale与keyboardlayout的对应规则，或者去哪里可以查阅到这些资料。

Answer 1

private void visitAllKeyboardLayouts(KeyboardLayoutVisitor visitor) {
        final PackageManager pm = mContext.getPackageManager();
        Intent intent = new Intent(InputManager.ACTION_QUERY_KEYBOARD_LAYOUTS);
        for (ResolveInfo resolveInfo : pm.queryBroadcastReceivers(intent,
                PackageManager.GET_META_DATA | PackageManager.MATCH_DIRECT_BOOT_AWARE
                        | PackageManager.MATCH_DIRECT_BOOT_UNAWARE)) {
            final ActivityInfo activityInfo = resolveInfo.activityInfo;
            final int priority = resolveInfo.priority;
            visitKeyboardLayoutsInPackage(pm, activityInfo, null, priority, visitor);
        }
    }看起来还是挺明显的，需要外部应用提供信息，搜索下github镜像InputDevices/AndroidManifest，剩下应该是你的专职工作我也就不太清楚了。<manifest xmlns:android="http://schemas.android.com/apk/res/android"
        package="com.android.inputdevices"
        coreApp="true"
        android:sharedUserId="android.uid.system">    <application
            android:allowClearUserData="false"
            android:label="@string/app_label"
            android:process="system"
            android:defaultToDeviceProtectedStorage="true"
            android:directBootAware="true">        <receiver android:name=".InputDeviceReceiver"
                android:label="@string/keyboard_layouts_label">
            <intent-filter>
                <action android:name="android.hardware.input.action.QUERY_KEYBOARD_LAYOUTS" />
            </intent-filter>
            <meta-data android:name="android.hardware.input.metadata.KEYBOARD_LAYOUTS"
                    android:resource="@xml/keyboard_layouts" />
        </receiver>
    </application>
</manifest>
