SwitchCompat RTL支持

Question

似乎track属性的选择器文件在RTL中不能正常工作。

track和thumb.

RTL、track和thumb。在这里，thumb被正确地更改了，但是track图像仍然没有改变，因为它应该在右边显示地图图标。

<androidx.appcompat.widget.SwitchCompat
        android:background="@drawable/selector_switch_track"
        android:elevation="6dp"
        android:outlineProvider="background"
        android:thumb="@drawable/selector_switch_thumb"
        app:track="@drawable/selector_switch_track" />

selector_switch_track.xml

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android" android:autoMirrored="true">
    <item android:state_checked="true">
        <layer-list>
            <item>
                <shape android:shape="rectangle">
                    <solid android:color="@color/global_white" />
                    <corners android:radius="@dimen/margin_100dp" />
                </shape>
            </item>
            <item android:drawable="@drawable/layer_switch_thumb_map_off" android:gravity="start" android:right="@dimen/margin_56dp" />
            <item android:drawable="@drawable/layer_switch_thumb_list_off" android:gravity="end" android:left="@dimen/margin_56dp" />
        </layer-list>
    </item>
    <item android:state_checked="false">
        <layer-list>
            <item>
                <shape android:shape="rectangle">
                    <solid android:color="@color/global_white" />
                    <corners android:radius="@dimen/margin_100dp" />
                </shape>
            </item>
            <item android:drawable="@drawable/layer_switch_thumb_map_off" android:gravity="start" android:right="@dimen/margin_56dp" />
            <item android:drawable="@drawable/layer_switch_thumb_list_off" android:gravity="end" android:left="@dimen/margin_56dp" />
        </layer-list>
    </item>
</selector>

我通过为RTL创建单独的res drawable-ldrtl来解决这个问题，并将相同的selector文件放在那里，但使用了切换的启动/结束绘图。
