This is how you create the dialogs I showed in the screenshots

MainActivity.java

		DialogInterface.OnClickListener dialogClickListener = new DialogInterface.OnClickListener()
		{
			@Override
			public void onClick(DialogInterface dialog, int which)
			{
				switch (which)
				{
					case DialogInterface.BUTTON_POSITIVE:
						Log.d("TAG", "User pressed start");
						break;

					case DialogInterface.BUTTON_NEGATIVE:
						dialog.dismiss();
						break;
				}
			}
		};

		LayoutInflater inflater = (LayoutInflater) getSystemService(LAYOUT_INFLATER_SERVICE);
		
		//Normal AlertDialog
		new AlertDialog.Builder(this)
				.setView(inflater.inflate(R.layout.content, null))
				.setTitle("Start a new ai game?")
				.setPositiveButton("Start", dialogClickListener)
				.setNegativeButton("Close", dialogClickListener);

		//My AlertDialog
		new AlertDialog.Builder(this)
				.setCustomTitle(inflater.inflate(R.layout.title,null)) //The title's TextView's style should be the
				// same as the the one of the dialog normal AlertDialog's Title Style (see example above)
				.setView(inflater.inflate(R.layout.content, null))
				.setPositiveButton("Start", dialogClickListener)
				.setNegativeButton("Close", dialogClickListener)
				.show();
