Like @krishna but in kotlin

  val builder = AlertDialog.Builder(context)
    val inflater = requireActivity().layoutInflater

    val dialogView = inflater.inflate(R.layout.fav_dialog, null)
    val name = dialogView.findViewById<EditText>(R.id.username)

    builder.setView(dialogView)
        .setPositiveButton("Add") { dialog, id ->
            val foxName = name.text.toString()
            Log.v("miapp", "Myfox $foxName")
        }
        .setNegativeButton("Cancel") { dialog, id ->
            dialog.cancel()
        }

    builder.setTitle("Add to favs")
    builder.setCancelable(false).create().show()

EditText editText = (EditText) findViewById(R.id.edit_message);
String message = editText.getText().toString();

An alternative to matsjoe and to krishna (both work):

builder.setPositiveButton(R.string.signin, new DialogInterface.OnClickListener() {
    //@Override
    public void onClick(DialogInterface dialog, int id) {
      // sign in the user ...

      Dialog dialogObj =Dialog.class.cast(dialog);
      EditText etUsr=(EditText) dialogObj.findViewById(R.id.username_id_value);
      userStr = etUsr.getText().toString();      
    }
  }
  );

If you want to inflate a xml file into dialog box for creating custom version you can use the following code which gets two input from user

LayoutInflater linf = LayoutInflater.from(this);            
final View inflator = linf.inflate(R.layout.twoinputs, null);
AlertDialog.Builder alert = new AlertDialog.Builder(this); 

alert.setTitle("Tilte"); 
alert.setMessage("Message"); 
alert.setView(inflator); 

final EditText et1 = (EditText) inflator.findViewById(R.id.editText1);
final EditText et2 = (EditText) inflator.findViewById(R.id.editText2);

alert.setPositiveButton("ok", new DialogInterface.OnClickListener() { 
   public void onClick(DialogInterface dialog, int whichButton) 
   { 
          String s1=et1.getText().toString();
          String s2=et2.getText().toString();
          //do operations using s1 and s2 here...
   } 
}); 

alert.setNegativeButton("Cancel", new DialogInterface.OnClickListener() { 
   public void onClick(DialogInterface dialog, int whichButton) { 
            dialog.cancel(); 
   } 
}); 

alert.show();

Hope it will help you.

private void inputFromDialog() {

    final Dialog dialog = new Dialog(SplashActivity.this);
    dialog.setContentView(R.layout.view_dialog);
    dialog.setTitle("Title");
    dialog.setCancelable(false);
    dialog.show();

    Button button = (Button) dialog.findViewById(R.id.continue_BTN);
    button.setOnClickListener(new View.OnClickListener() {
        public void onClick(View v) {

            EditText inputET=(EditText)dialog.findViewById(R.id.input_ET);


            if (inputET.getText().toString().equals("")){

                inputET.setError("This field is required");

            }else {

                mssid = inputET.getText().toString();
                dialog.cancel();
                Toast.makeText(SplashActivity.this, mssid, Toast.LENGTH_SHORT).show();
            }

        }
    });

You are inflating a layout where it is not needed. I fixed your code as you see I removed your line where it inflates and changed the line where you try to find the EditText view.

final Dialog dialog = new Dialog(MyActivity.this);
 dialog.setContentView(R.layout.custom_dialog);
 dialog.setTitle("Title");

 Button button = (Button) dialog.findViewById(R.id.dialog_ok);
 button.setOnClickListener(new OnClickListener() {
     public void onClick(View v) {

            EditText edit=(EditText)dialog.findViewById(R.id.dialog_edit);
            String text=edit.getText().toString();

            dialog.dismiss();
            name=text;

     }
 });   


dialog.show();
