The easiest way is to subclass a dialog by creating a class which extends dialog and implements the constructor which take style as a parameter. Then make your own custom layout to it.

The Code to show the dialog:

private void showDialog()
{
    Custom_Dialog dialog = new Custom_Dialog(this, R.style.myCoolDialog);

    dialog.setContentView(R.layout.custom_dialog);
    dialog.setTitle("Custom Dialog");

    TextView text = (TextView) dialog.findViewById(R.id.text);
    text.setText("Hello, this is a custom dialog!");
    ImageView image = (ImageView) dialog.findViewById(R.id.image);
    image.setImageResource(R.drawable.icon);

    dialog.show();  
}

The code for the subclass:

package com.stackoverflow;

import android.app.Dialog;
import android.content.Context;

public class Custom_Dialog extends Dialog {

    protected Custom_Dialog(Context context, int theme) {
        super(context, theme);
        // TODO Auto-generated constructor stub
    }

}

the style: myCoolDialog.xml

and last the layout:custom_dialog.xml
