android - How can can I add custom buttons into an AlertDialog's layout?

Question

I have AlertDialog with Positive and Negative buttons. In AlertDialog layout I have EditText and two Buttons (btnAdd1, btnAdd2). I want when user click at the Button btnAdd1 or btnAdd2 add same text to EditText in AlertDialog (but no close AlertDialog). Is this possible do in AlertDialog or I have to use only Dialog?

This is layout (R.layout.prompt) of AlertDialog:

<LinearLayout>
<EditText
    android:id="@+id/userInput"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:inputType="text" >

    <requestFocus />
</EditText>

<Button
    android:id="@+id/btnAdd1"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:text="bla" />

<Button
    android:id="@+id/btnAdd2"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:text="bla" />

  </LinearLayout>

And this is source code:

    LayoutInflater layoutInflater = LayoutInflater.from(this);
        View promptView = layoutInflater.inflate(R.layout.prompt, null);

    AlertDialog.Builder alertDialogBuilder = new AlertDialog.Builder(this);
    alertDialogBuilder.setView(promptView);
    alertDialogBuilder
            .setCancelable(false)
            .setPositiveButton("OK", new DialogInterface.OnClickListener() {
                public void onClick(DialogInterface dialog, int id) {
                              //...

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

    AlertDialog alertD = alertDialogBuilder.create();
    alertD.show();

I want get acces to the btnAdd1 and btnAdd2 from the layout. Set the OnClickListener() to these two buttons.

The following code will inflate a view from R.layout.prompt and set it to the AlertDialog. The positive and negative buttons will not be used. You can set the onClick behaviors for btnAdd1 and btnAdd2:

LayoutInflater layoutInflater = LayoutInflater.from(this);
View promptView = layoutInflater.inflate(R.layout.prompt, null);

final AlertDialog alertD = new AlertDialog.Builder(this).create();

EditText userInput = (EditText) promptView.findViewById(R.id.userInput);

Button btnAdd1 = (Button) promptView.findViewById(R.id.btnAdd1);

Button btnAdd2 = (Button) promptView.findViewById(R.id.btnAdd2);

btnAdd1.setOnClickListener(new OnClickListener() {
    public void onClick(View v) {

        // btnAdd1 has been clicked

    }
});

btnAdd2.setOnClickListener(new OnClickListener() {
    public void onClick(View v) {

        // btnAdd2 has been clicked

    }
});

alertD.setView(promptView);

alertD.show();
