Q:

Is it possible to setup background in style for all ImageView in application

I know i could create some style and set it like this.
<ImageView
        style="@style/MyCustomStyle" />

But I couldn't find an opportunity to setup it directly for whole application as default style for example like TextView.
<style name="AppTheme" parent="Theme.AppCompat.Light.NoActionBar">
    <item name="colorPrimary">@color/colorPrimary</item>
    <item name="colorPrimaryDark">@color/colorPrimaryDark</item>
    <item name="colorAccent">@color/colorAccent</item>
    <item name="android:textViewStyle">@style/CustomTextStyle</item>
</style>

Also I can't find parent ImageView wiget style. 
<style name="MyCustomStyle" parent="android:Widget.???"/>

Is it possible with ImageView.

A:

You would rather create a custom ImageView and add style to it. Then use the CustomImageView and it'll have the same style through out the app
