Android – set padding / margins as the top activity / fragment layout container in the theme?

In my application, I want to fill all screen top-level containers that apply to themes

For example:

This is the layout file

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    tools:context=".MainActivity">

    <EditText
        android:id="@+id/edt"
        android:layout_width="match_parent"
        android:layout_height="wrap_content" />

</RelativeLayout>

This is the application theme

<!-- Base application theme. -->
    <style name="AppTheme" parent="Theme.AppCompat.Light">
        <!-- Customize your theme here. -->
        <item name="colorPrimary">@color/colorPrimary</item>
        <item name="colorPrimaryDark">@color/colorPrimaryDark</item>
        <item name="colorAccent">@color/colorAccent</item>
        <item name="android:windowFrame">@drawable/window_frame</item>
    </style>

I can use Android: padding to apply padding to the parent container relativelayout. But I don't want to, because I need to specify the same content in each layout file. I want to define it in the theme apptheme

Any solution would be appreciated

Why do you need to write additional code that uses styles?

You can set padding directly in RES / values / dimensions.xml, which is much easier. Whenever you need to increase or decrease values, you only need to change it in a single location for each activity

For example, in dimensions.xml

<dimen name="my_activity_padding">5dp</dimen> 

Then in the active layout:

android:padding="@dimen/activity_padding"
