If you set clipsToBounds to true, this will round the corners but prevent the shadow from appearing. In order to resolve this, you can create two views. The container view should have the shadow, and its subview should have the rounded corners. The container view has clipsToBounds set to false, and has the shadow properties … Read more
UPDATE FOR iOS 7.0 In iOS 7.0, Apple added a new attribute, NSTextEffectAttributeName, for attributed strings. If your deployment target is iOS 7.0 or later, you can set this attribute to NSTextEffectLetterpressStyle to draw an attributed string in an embossed style. ORIGINAL I can’t say for certain how Apple draws the embossed text. It looks … Read more
In my option the best way is to add Material() over the widget you are currently using. return Material( elevation: 20, child: Container(), );
We can also use CardView which provides a rounded corner background and shadow. To use that you need to add the v7 CardView library as a dependency to the project in the build.gradle like below. dependencies { compile ‘com.android.support:cardview-v7:23.0.1’ ——- } Note: Change 23.0.1 in the above line with the respected version. So I surrounded … Read more
I know that this question is very old and probably the author doesn’t need the answer anymore. I’ll just leave it here so others can find it. Lollipop’s elevation system doesn’t support colored shadows. But, if you need colored shadows, it’s possible to get them using Carbon. It’s a kind-of support library for Material Design … Read more
This worked for me very well: <android.support.v7.widget.CardView xmlns:card_view=”http://schemas.android.com/apk/res-auto” android:layout_width=”match_parent” android:layout_height=”wrap_content” android:background=”@color/primary” card_view:cardElevation=”4dp” card_view:cardCornerRadius=”0dp”> <android.support.v7.widget.Toolbar android:id=”@+id/toolbar” android:layout_width=”match_parent” android:layout_height=”wrap_content” android:background=”@color/primary” android:minHeight=”?attr/actionBarSize” /> </android.support.v7.widget.CardView>
You can use overflow: ‘hidden’ to achieve the desired result without having to install a library. wrap the view in a parent view and set the parent’s overflow to hidden and apply a padding only on the side where you want your shadow to appear like so: <View style={{ overflow: ‘hidden’, paddingBottom: 5 }}> <View … Read more
Consider this thread in twitter, where Nick Butcher talks about how to implement the feature: See outlineAmbientShadowColor, outlineSpotShadowColor, spotShadowAlpha and ambientShadowAlpha attributes for details. Unfortunately, that’s possible from API 28 onwards. For lower APIs Nick has shared a gist. Here’s the result: Running on API 21 This technique isn’t directly connected to CardView, it can … Read more
I think the proper way of thinking of shadow is, the shadow belongs to the object, which is the button, the uiview, not just part of the side. Imagining there is a virtual light source. You can’t really just create a shadow for one side. With that being said, the shadow will always be the … Read more
There is a fourth distance you can define called the spread offset, which moves the shadow in or out on all 4 sides. So if you set that to the negative of the blur distance, this will shift the shadow inwards by the same distance as the blur extends the shadow outwards effectively hiding it. … Read more
