如何将BottomSheetDialogFragment主题与其他主题结合?
我的应用程序具有使用主题制作的皮肤。BottomSheetDialogFragment应该有圆角,我使用以下方法实现:
override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
setStyle(BottomSheetDialogFragment.STYLE_NORMAL, R.style.CustomBottomSheetDialogTheme) /* hack to make background transparent */
}

然后在styles.xml:
<style name="CustomBottomSheetStyle" parent="Widget.Design.BottomSheet.Modal">
<item name="android:background">@android:color/transparent</item>
</style>
<style name="CustomBottomSheetDialogTheme" parent="Theme.MaterialComponents.Light.BottomSheetDialog">
<item name="bottomSheetStyle">@style/CustomBottomSheetStyle</item>
</style>

但是如果我从 扩展,Theme.MaterialComponents.Light.BottomSheetDialog我不会得到我在皮肤主题中定义的配色方案。
那么问题来了:如何在皮肤主题里面定义Dialog主题呢?
您可以在您的应用主题中添加bottomSheetDialogTheme属性,以便在您的应用中全局设置 bottomsheetDialog 样式。
<style name="AppTheme" parent="Theme.MaterialComponents.*">
......
<item name="bottomSheetDialogTheme">@style/BottomSheetDialog_Rounded</item>
</style>
<style name="BottomSheetDialog_Rounded" parent="@style/ThemeOverlay.MaterialComponents.BottomSheetDialog">
<item name="bottomSheetStyle">@style/BottomSheet_Rounded</item>
</style>

否则,在您的 BottomSheetDialogFragment 中,您可以覆盖该getTheme()方法。
public class RoundedBottomSheetDialog extends BottomSheetDialogFragment {
//....
@Override public int getTheme() {
return R.style.BottomSheetDialog_Rounded;
}
}

同样要获得圆角,您可以使用以下内容:
<!-- BottomSheet Dialog-->
<style name="BottomSheetDialog_Rounded" parent="@style/ThemeOverlay.MaterialComponents.BottomSheetDialog">
<item name="bottomSheetStyle">@style/BottomSheet_Rounded</item>
</style>
<style name="BottomSheet_Rounded" parent="Widget.MaterialComponents.BottomSheet">
<item name="shapeAppearanceOverlay">@style/ShapeAppearanceBottomSheetDialog_Rounded</item>
</style>
<style name="ShapeAppearanceBottomSheetDialog_Rounded" parent="">
<item name="cornerFamily">rounded</item>
<item name="cornerSizeTopRight">16dp</item>
<item name="cornerSizeTopLeft">16dp</item>
<item name="cornerSizeBottomRight">0dp</item>
<item name="cornerSizeBottomLeft">0dp</item>
</style>

override fun onCreateDialog(@Nullable savedInstanceState: Bundle?): Dialog
val dialog = BottomSheetDialog(context!!,R.style.FullScreenBottomSheet)
<style name="FullScreenBottomSheet"
parent="Theme.MaterialComponents.Light.BottomSheetDialog">
<item name="android:windowFullscreen">false</item>
<item name="android:colorBackgroundCacheHint">@null</item>
<item name="android:windowBackground">@color/transparent</item>
<item name="android:statusBarColor">@color/transparent</item>
</style>
