Ask for help : Package titlesec affects the settings of tocloft

Hello, everyone.

 I am facing a problem when formatting my report edited by Latex.

I wanto to do the following two formatting

1.  to supress the line break after chapter title, for example
   Chapter 1 Exercise A
  to replace the default one
  Chapter 1
    Exercise  A

2. to append "Appendix x........#"' to TOC, replacing default "x........#"


I use package titlesec to do format 1 and use package tocloft to do format
2.
But I found the two package affect each other.
I can not get the two format at the same time.

Anyone can help me some, thanks in advance.

The following is the my minimal example.



\documentclass[a4paper,openany]{book}

\usepackage{tocloft}

\usepackage{titlesec}

\usepackage{nonumonpart}   %dont display page number on part cover page

%to append "Appendix x........#"' to TOC, replacing default "x........#"
\renewcommand{\partname}{Appendix}
\makeatletter
\@addtoreset{chapter}{part}
\makeatother
\newlength\mylen
\renewcommand\thepart{\Roman{part}}
\renewcommand\cftpartpresnum{\Large Appendix~}
\settowidth\mylen{\bfseries\cftpartpresnum\cftpartaftersnum}
\addtolength\cftpartnumwidth{\mylen}


%to supress the line break after chapter title
\titleformat{\chapter}% reformat chapter headings
    [hang]% like section, with number on same line
    {\Huge\bfseries}% formatting applied to whole
    {\thechapter}% Chapter number
    {0.5em}% space between # and title
    {}% formatting applied just to title
        %
