ShapeableImageView doesnt round corners

ShapeableImageView takes a ShapeAppearanceOverlay item in style to create desired shapes and sizes. The shape families are cut and rounded, radius can be used as a number or in percentages.
Here is my ShapeAppearanceOverlay theme for circularImageView:
<style name="ShapeAppearanceOverlay.App.circleImageView" parent="">
<item name="cornerFamily">cut</item>
<item name="cornerSize">50%</item>
</style>
Here Is the layout where I am using it:
<RelativeLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#color/grey"
android:orientation="vertical">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="240dp" />
<!--Top Header Layout-->
<ScrollView
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_below="#+id/topbar"
android:scrollbars="none">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical">
<!--Top Profile Section -->
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content">
<com.google.android.material.imageview.ShapeableImageView
android:id="#+id/user_display_image"
style="#style/ShapeAppearanceOverlay.App.circleImageView"
android:layout_width="100dp"
android:layout_height="100dp"
android:src="#drawable/ic_user" />
</LinearLayout>
<androidx.fragment.app.FragmentContainerView
android:id="#+id/fragment_container"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:paddingBottom="#dimen/normal_bottom_margin" />
</LinearLayout>
</ScrollView>
</RelativeLayout>
Here is a screenshot of the issue:
Screenshot from IDE:

Use app:shapeAppearanceOverlay instead of style
<com.google.android.material.imageview.ShapeableImageView
app:shapeAppearanceOverlay="#style/ShapeAppearanceOverlay.App.circleImageView"
.../>

Or if you want to use it through style attribute :
<style name="Style.App.circleImageView" parent="">
<item name="shapeAppearance">#style/ShapeAppearanceOverlay.App.circleImageView</item>
</style>
<style name="ShapeAppearanceOverlay.App.circleImageView" parent="">
<item name="cornerFamily">cut</item>
<item name="cornerSize">50%</item>
</style>
...
<com.google.android.material.imageview.ShapeableImageView
android:id="#+id/user_display_image"
style="#style/Style.App.circleImageView"
android:layout_width="100dp"
android:layout_height="100dp"
android:src="#drawable/ic_user" />

To make your toolbar "back" arrow and overflow icon light, while maintaining a light themed popup menu:
Add a toolbar style in your style.xml file(s):
<style name="AppTheme.Toolbar" parent="ThemeOverlay.AppCompat.Dark.ActionBar">
<item name="popupTheme">#style/ThemeOverlay.AppCompat.Light</item>
<item name="theme">#style/ThemeOverlay.AppCompat.Dark.ActionBar</item>
</style>
Set the new style to your Toolbar layout:
<android.support.v7.widget.Toolbar
xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/toolbar"
android:layout_width="match_parent"
android:layout_height="?android:attr/actionBarSize"
style="#style/AppTheme.Toolbar"/> <!-- Added style -->
This will give your Toolbar a dark themed (white) arrow and overflow icon, but will keep your popup menu light.
Taken from (original link) here: https://stackoverflow.com/a/33833931/2905354
This works perfectly and has the added benefit of making your app easier to theme.

I faced this problem, I just tried to set my own drawable as back button like this :
final Drawable your_drawable = getResources().getDrawable(R.drawable.back_arrow);
upArrow.setColorFilter(getResources().getColor(R.color.white), PorterDuff.Mode.SRC_ATOP);
getSupportActionBar().setHomeAsUpIndicator(your_drawable);

Translucent Activity does not fit window height

I am trying to make a translucent search activity with variable height - wrap content on RecyclerView to be exact. Unfortunately, I am not able to fit screen height and end up with weird margin at the bottom, as seen on screenshot.
Here is my activity layout
<android.support.design.widget.CoordinatorLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:layout_width="match_parent"
android:layout_height="wrap_content">
<android.support.design.widget.AppBarLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="#color/white"
android:theme="#style/WeatherTheme.AppBarOverlay">
<android.support.v7.widget.Toolbar
android:id="#+id/toolbar"
style="#style/AppBarStyle.Main"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
app:logo="#null" />
</android.support.design.widget.AppBarLayout>
<FrameLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
app:layout_behavior="#string/appbar_scrolling_view_behavior">
<android.support.v7.widget.RecyclerView
android:id="#+id/suggestionsContainer"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="#color/white"
android:visibility="gone" />
<TextView
android:id="#+id/emptyResults"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="#color/white"
android:padding="16dp"
android:text="#string/not_found"
android:textSize="22sp"
android:visibility="gone" />
<FrameLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="#color/white">
<ProgressBar
android:id="#+id/loading"
android:layout_width="26dp"
android:layout_height="26dp"
android:layout_gravity="center"
android:background="#color/white"
android:layout_margin="14dp"
android:visibility="gone" />
</FrameLayout>
</FrameLayout>
</android.support.design.widget.CoordinatorLayout>
And theme used for this activity is MainTheme.NoActionBar.Search
<style name="MainTheme" parent="Theme.AppCompat.Light">
<item name="colorPrimary">#color/theme_color_primary</item>
<item name="colorPrimaryDark">#color/theme_color_primary_dark</item>
<item name="colorAccent">#color/theme_color_accent</item>
<item name="colorControlHighlight">#color/theme_color_highlight</item>
<item name="android:textColorPrimary">#color/theme_text_color_primary</item>
<item name="android:windowBackground">#color/theme_color_background</item>
</style>
<style name="MainTheme.NoActionBar">
<item name="windowActionBar">false</item>
<item name="windowNoTitle">true</item>
</style>
<style name="MainTheme.NoActionBar.Search" >
<item name="android:windowIsTranslucent">true</item>
<item name="android:windowBackground">#android:color/transparent</item>
<item name="android:backgroundDimEnabled">true</item>
<item name="android:backgroundDimAmount">0.5</item>
<item name="android:windowAnimationStyle">#android:style/Animation.Dialog</item>
</style>
Will appreciate any hints on what might cause the problem!

After changing to app:elevation

I was able to fix my erro by removing this on my Android Manifest:
android:hardwareAccelerated="false"

use this if you are using support library for older versions too
app:elevation
use this if you are not using support library
android:elevation
