Bottom Sheet Dialog - Android Studio - Java

How to create and show Bottom Sheet Dialog

In this tutorial, we will learn how to implement a Bottom Sheet Dialog in Android Studio using Java. Bottom Sheet Dialogs are a modern UI component from Material Design that slide up from the bottom of the screen to display additional content or actions without leaving the current screen.

Example Use Cases:

• Share options
• Quick action menus
• Simple forms or confirmations

>> Check For Java
>> Check For Kotlin
>> Check For Compose
