	setIcon(R.drawable.ic_launcher).
	setPositiveButton("确定", new DialogInterface.OnClickListener() {
		   @Override
		   public void onClick(DialogInterface dialog, int which) {
		      // TODO Auto-generated method stub
		   }
		}).
		setNegativeButton("取消", new DialogInterface.OnClickListener() {		     
		   @Override
		   public void onClick(DialogInterface dialog, int which) {
		      // TODO Auto-generated method stub
