Create a custom dialog you can customize it as you wish. In the dialog box layout xml file

surround your RelativeLayout or LinearLayout with scrollable like below code

<ScrollView
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:scrollbars="vertical"
    android:scrollbarAlwaysDrawVerticalTrack="true"
    android:orientation="vertical"
    android:layout_weight="1">

    <!--Your other text views, buttons... etc surrounded by RelativeLayout
or LinearLayout goes here-->

</ScrollView>

When the content exceeds dlalog box size it will display the scroll bar. Hope this will help you :)
