Custom style for all ImageView widgets

Question

The following code shows how you could prepare a custom style for all TextView widgets.

<style name="CustomTheme.TextView" parent="android:Widget.TextView">
    <item name="android:background">@color/viewBackground</item>
    <item name="android:textColor">@color/viewTextColor</item>
    <item name="android:textSize">@denim/viewTextSize</item>
</style>

How do I fix the following custom style for all ImageView widgets? I'm asking since I can't seem to find any such Widget.

<style name="CustomTheme.ImageView" parent="android:Widget.???">-->
</style>

The only Image related Widgets, in the list, are ImageButton and ImageWell.

`ImageView` doesn't have a defined style attribute, so you can't really do that with it as is. As you've noticed, `ImageButton` does, though, so if you can use those instead, that would be the easiest solution. — Mike M., Jan 23 '19 at 18:48
@MikeM. : I just tried just using "android:Widget" as the parent, to the style, and it seem to affect the ImageView in question. — goldenmaza, Jan 24 '19 at 07:53
Maybe I'm not understanding what you're asking, exactly. How are you setting that style on the `ImageView`s? — Mike M., Jan 24 '19 at 07:56
@MikeM. : With the style attribute: style="@style/CustomTheme.ImageView.Large" — goldenmaza, Jan 24 '19 at 08:38
Ah, OK, I thought you were asking how to style all of your `ImageView`s through a single attribute in your theme, like with `textViewStyle`. In that case, you don't need a `parent` style. Just remove it. — Mike M., Jan 24 '19 at 08:45
@MikeM. : I wanted that first yes, but since there is no attribute like that then I had to take this backwards solution by adding style attributes everywhere. I would have prefered an "imageViewStyle", yes. — goldenmaza, Jan 24 '19 at 08:54

you can define custom style like this

<style name="iconStyle" >
        <item name="android:contentDescription">""</item>
        <item name="android:clickable">true</item>
        <item name="android:focusable">true</item>
        <item name="android:padding">@dimen/size_12dp</item>
        <item name="android:background">?attr/selectableItemBackgroundBorderless</item>
</style>

then pass this style to your image view like this

<ImageView
    style="@style/iconStyle"
    android:layout_width="@dimen/size_48dp"
    android:layout_height="@dimen/size_48dp"
    android:src="@drawable/ic_search"
    android:id="@+id/imgSearch"/>

If you are not able to find `style.xml` file then, just add this `style="@style/iconStyle"` line and then click on `Error Alert toggle` and create new `style` for `day/night` then Android studio automatically create this file for your project. You can access and use. — TexD, Jan 14 '23 at 10:14
