Simple example of using BottomSheetDialog in Android | Kotlin

BottomSheetDialog is simple dialog styled as bottom sheet.

BottomSheetDialog implementation is quite simpler and easier than normal Dilaogs. You can just attach view for it and then display it.

Here is simple example. This tutorial is developed using kotlin.
MainActivity.kt

val dialog = BottomSheetDialog(this)
val bottomSheet = layoutInflater.inflate(R.layout.bottom_sheet, null)

bottomSheet.buttonSubmit.setOnClickListener { dialog.dismiss() }
        
dialog.setContentView(bottomSheet)
dialog.show()

bottom_sheet.xml

<?xml version="1.0" encoding="utf-8"?>
<android.support.constraint.ConstraintLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    android:id="@+id/bottomSheet"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:padding="10dp">

    <TextView
        android:id="@+id/textMessage"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="This is the BottomSheetDialog, you can use this instead of normal Dialogs."
        android:textColor="#000"
        android:textSize="16sp"
        app:layout_constraintTop_toTopOf="parent" />

    <Button
        android:id="@+id/buttonSubmit"
        style="@style/Widget.AppCompat.Button.Borderless"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_margin="5dp"
        android:text="OKAY"
        app:layout_constraintBottom_toBottomOf="parent"
        app:layout_constraintEnd_toEndOf="parent"
        app:layout_constraintStart_toStartOf="parent"
        app:layout_constraintTop_toBottomOf="@+id/textMessage" />
