The basic method of showing a dialog is like so:-----------------------
// Note: A second constructor exists to pass in a theme res ID
MaterialAlertDialogBuilder(context)
    // Add customization options here
.show()
  
Title and supporting text-------------------
// Title
.setTitle("Title")
// Supporting text
.setMessage("Supporting text")

Action buttons-----------------------------
// Confirming action
.setPositiveButton("Confirm") { dialog, which ->
    // Do something for button click
}
// Dismissive action
.setNegativeButton("Dismiss") { dialog, which ->
    // Do something for button click
}
// Neutral action
.setNeutralButton("Neutral") { dialog, which ->
    // Do something for button click
}


--------------------------- Set View
final View customLayout = getLayoutInflater().inflate(R.layout.activity_intro, null);
final EditText et_user_name = customLayout.findViewById(R.id.et_user_name);
// define click listener or any work

new MaterialAlertDialogBuilder(getActivity())
.setView(customLayout)
