在Android Studio上面直接操作Version Control的reword是最直接的。

    用git的方式来：

    1. git rebase -i HEAD~1

    打开了文本编辑器

    1. pick 10130de msg
    3. # Rebase da71f75..10130de onto da71f75 (1 command)
    4. #
    5. # Commands:
    6. # p, pick <commit> = use commit
    7. # r, reword <commit> = use commit, but edit the commit message
    8. # e, edit <commit> = use commit, but stop for amending
    9. # s, squash <commit> = use commit, but meld into previous commit
    10. # f, fixup <commit> = like "squash", but discard this commit's log message
    11. # x, exec <command> = run command (the rest of the line) using shell
    12. # d, drop <commit> = remove commit
    13. # l, label <label> = label current HEAD with a name
    14. # t, reset <label> = reset HEAD to a label
    15. # m, merge [-C <commit> | -c <commit>] <label> [# <oneline>]
    16. # .       create a merge commit using the original merge commit's
    17. # .       message (or the oneline, if no original merge commit was
    18. # .       specified). Use -c <commit> to reword the commit message.
    19. #
    20. # These lines can be re-ordered; they are executed from top to bottom.
    21. #
    22. # If you remove a line here THAT COMMIT WILL BE LOST.
    23. #
    24. #    However, if you remove everything, the rebase will be aborted.
    25. #
    26. #    
    27. # Note that empty commits are commented out

    保存，关闭。
    git显示命令：

    1. $ git rebase -i HEAD~1
    2. hint: Waiting for your editor to close the file...

    然后打开了文本编辑器，显示的就是

    1. msg
    2. //提示信息

    这里把msg改成123456798，然后保存，关闭。

    1. $ git rebase -i HEAD~1
    2. [detached HEAD 951f653] 123456789
    3.  Date: Fri Jul 20 15:26:26 2018 +0800
    4.  1 file changed, 0 insertions(+), 0 deletions(-)
    5.  create mode 100644 新建文本文档.txt
    6. Successfully rebased and updated refs/heads/master.

    这个时候commit信息已经修改，并且也改了版本快照的hash值。
