[BottomSheetDialog] MaterialButton in BottomSheetDialog will be forced to single-line

[Back4fire]

MaterialButton in BottomSheetDialog will be forced to single-line. With the Layout Inspector, I found singleLine==ture and maxLines==1. But I never set these values explicitly. The bug starts from Material 1.4.0. And still exists in 1.5.0-alpha02.

The following is a very simple layout, a Button in a FrameLayout.

<?xml version="1.0" encoding="utf-8"?> <FrameLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="match_parent" android:layout_height="300dp">

<Button
    android:id="@+id/button"
    android:layout_width="150dp"
    android:layout_height="wrap_content"
    android:layout_gravity="center"
    android:text="I will be forced to be single-line in Bottom Sheet Dialog with Material Lib 1.4.0+" />

This screenshot is compiled with Material 1.3.0. Everything is correct.

This screenshot is compiled with Material 1.4.0. The Button is single-line.

The layouts in my project related to this bug are broken. If there is any workaround before it can be fixed, please let me know.

I thought the MD team doesn't treat it as a bug.😁 But it's unreasonable to make the style of MaterialButton in BottomSheetDialog like that in AlertDialog. We usually put complicated UI in BottomSheetDialog.

Yeah, I agree

Yes, it's working as designed.

If you want to change the button style, you can extend ThemeOverlay.MaterialComponents.BottomSheetDialog and override ?attr/MaterialButtonStyle to the style you like, and set your main theme's ?attr/bottomSheetDialogTheme to the custom theme.
