英文:
how to set "app:backgroundTint" via style?
问题
我想要替换：
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
app:backgroundTint = "...",
...
android:orientation="horizontal">
为：
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
style="@style/My.Bg.Snackbar.DayNight"
...
android:orientation="horizontal">
和
<style name="My.Bg.Dark" parent="">
<item name="app:backgroundTint">@color/og_background_dark</item>
</style>
以及
<declare-styleable name="My">
<!-- The background color. -->
<attr name="app:backgroundTint" format="color" />
</declare-styleable>
</resources>
但是我得到一个错误：
error: resource app:attr/backgroundTint not found.
