How to create custom dialog box in android kotlin

 

1=> In Activity File (MainActivity.kt) :

override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
setContentView(R.layout.activity_Main)

//method 2 for show dialog box

val dialog=Dialog(this)
dialog.setContentView(R.layout.custom_dialog_box);
val btnOk= dialog.findViewById<Button>(R.id.btnOk)
if (btnOk != null) {
btnOk.setOnClickListener( {
Toast.makeText(this,"Success",Toast.LENGTH_LONG).show()
dialog.dismiss()
})}
dialog.show();

//method 2 for show dialog box

//
// val builder = AlertDialog.Builder(this)
// val inflater = LayoutInflater.from(this)
// val dialogView = inflater.inflate(R.layout.custom_dialog_box, null)
//
// builder.setView(dialogView)
//
// val dialog = builder.create()
// dialog.show()



}

2=> In Layout XML File (custom_dialog_box.xml):

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

<ImageView
android:layout_width="match_parent"
android:layout_height="70dp"
android:src="@drawable/add_reaction"/>

<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical"
android:background="@drawable/box_corner_radius"
>

<TextView
android:id="@+id/tsSuccess"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="Success"
android:layout_margin="20dp"
android:textStyle="bold"
android:textSize="30sp"
android:gravity="center"
android:textColor="#4CAF50"/>
<TextView
android:id="@+id/tsMessage"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="Booked "

android:layout_margin="20dp"
android:textStyle="bold"
android:textSize="16sp"
android:gravity="center"
android:textColor="#060706"/>

<Button
android:id="@+id/btnOk"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:gravity="center"
android:layout_margin="20dp"
android:padding="20dp"
android:text="Ok"
/>

</LinearLayout>
</LinearLayout>

3=> In Drawable File (box_corner_radius.xml) :

?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android">
<corners
android:bottomLeftRadius="30dp"
android:bottomRightRadius="30dp"
android:topLeftRadius="30dp"
android:topRightRadius="30dp" />
<solid android:color="#1271BB" />

<stroke
android:width="5dp"
android:color="#1271BB" />

<padding
android:bottom="1dp"
android:left="1dp"
android:right="1dp"
android:top="1dp" /></shape>
