Kotlin - custom dialog in Android

Question

I want to create a custom dialog in Kotlin. I looked through questions on this theme on Stack Overflow, but I could not find any useful information. How can I do it?

Answer 1

You can use below code for a custom Dialog. It's my working code.

 private fun showDialog(title: String) {
    val dialog = Dialog(activity)
    dialog.requestWindowFeature(Window.FEATURE_NO_TITLE)
    dialog.setCancelable(false)
    dialog.setContentView(R.layout.custom_layout)
    val body = dialog.findViewById(R.id.body) as TextView
    body.text = title
    val yesBtn = dialog.findViewById(R.id.yesBtn) as Button
    val noBtn = dialog.findViewById(R.id.noBtn) as TextView
    yesBtn.setOnClickListener {
        dialog.dismiss()
    }
    noBtn.setOnClickListener { dialog.dismiss() }
    dialog.show()

}

custom_dialog.xml

<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:background="@drawable/fitsdk_white_rectangle"
android:orientation="vertical">


    <LinearLayout
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_marginLeft="15dp"
        android:layout_marginTop="30dp"
        android:layout_marginRight="15dp"
        android:layout_marginBottom="30dp"
        android:orientation="vertical">

        <TextView
            android:id="@+id/tvTitle"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:text="@string/error_timeout_title"
            android:textColor="@color/black" />

        <TextView
            android:id="@+id/tvBody"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_marginTop="15dp"
            android:text="@string/error_timeout_body"
            android:textColor="@color/black" />

        <Button
            android:id="@+id/btn_yes"
            android:layout_width="100dp"
            android:layout_height="30dp"
            android:background="@android:color/white"
            android:clickable="true"
            android:text="Yes"
            android:textColor="#5DBCD2"
            android:textStyle="bold" />
    </LinearLayout>

</FrameLayout>

CustomDialogClass.kt

class CustomDialogClass(context: Context) : Dialog(context) {
    
        init {
            setCancelable(false)
        }
    
        override fun onCreate(savedInstanceState: Bundle?) {
            super.onCreate(savedInstanceState)
            requestWindowFeature(Window.FEATURE_NO_TITLE)
            setContentView(R.layout.custom_dialog)
