After changing my app from compiling/targeting SDK v25 to SDK v26, all of the menu icons in my app's toolbar are now squashed/squished/stretched.
Here's the relevant layout code:
<android.support.design.widget.AppBarLayout
android:id="@+id/appbar"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:theme="@style/ThemeOverlay.AppCompat.Dark.ActionBar">
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="wrap_content">
<android.support.v7.widget.Toolbar
android:id="@+id/toolbar"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
android:background="?attr/colorPrimary"
android:theme="@style/AppTheme.AppBarOverlay" />
<br.com.mauker.materialsearchview.MaterialSearchView
android:id="@+id/search_view"
android:layout_width="match_parent"
android:layout_height="match_parent" />
</RelativeLayout>
</android.support.design.widget.AppBarLayout>
Here's a menu that squishes:
<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto">
<item android:id="@+id/action_search"
android:title="@string/search"
android:icon="@drawable/ic_search_white_48dp"
app:showAsAction="ifRoom" />
<item
android:id="@+id/advanced_search"
android:enabled="true"
android:title="@string/advanced_search"
app:showAsAction="never" />
</menu>
Here's another menu that squishes (they all do):
<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto">
<item
android:id="@+id/add_photo"
android:enabled="true"
android:title="@string/add_photo"
android:icon="@drawable/ic_add_a_photo_white_48dp"
app:showAsAction="ifRoom" />
</menu>
