<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
                android:layout_width="match_parent"
                android:layout_height="wrap_content"
                android:orientation="vertical"
                android:background="@drawable/custom_dialog"
    >

Answer 1

Create a inset and set as background, that may help

<?xml version="1.0" encoding="utf-8"?>
<inset xmlns:android="http://schemas.android.com/apk/res/android"
    android:drawable="@drawable/your_background_image"
    android:insetRight="25dip"
    android:insetLeft="25dip" />

use

android:background="@drawable/inset_background"
