ZXing Embedded center horizontal prompt

Question

Well, had this doubt and found a simple solution. I'll share it below.

Answer 1

Create a style:

<style name="ZxingTheme" parent="zxing_CaptureTheme">
    <item name="android:fontFamily">@font/open_sans</item>
    <item name="android:gravity">center_horizontal</item>
</style>

Override in manifest:

<activity
    android:name="com.journeyapps.barcodescanner.CaptureActivity"
    android:screenOrientation="portrait"
    android:theme="@style/ZxingTheme"
    tools:replace="screenOrientation, theme" />

Result:
