Add Chinese(zh-CN) support

[chenzaichun]

Add simplified chinese translation.

[gerhardol]

Thanks, but translated files must be added to Transifex, it is from there translations are pulled.
It may be possible to push translations as well.

Are both zh and zh-rCN needed?

[gerhardol]

This list is intended to be in "alphabetic" sort order with local names. Is "Chinese" supposed to be sorted last like this?

[chenzaichun]

It's fine.

[gerhardol]

why this string?
(may be an old string)

[chenzaichun]

May be an old string, I translated it last year. I use RunnerUp everyday, so I thinks maybe there's someone would like it.

There're some other zh format, like zh-TW, zh-HK, which use traditional Chinese. Maybe someone could translate it.

[gerhardol]

The Chinese translation in Transifex is empty, so the translations can be pushed (I have not used that function though).
But zh and zh-CN is identical, so only one of them is really needed (I suggest zh).
In addition a squash and rebase is needed.
I can do that, but unless you have allowed maintainer changes, it must be done in a PR I create.

[gerhardol]

What to keep of zh or zh-CN?
There will be a difference for users of Android before 7 from what I can see in
https://developer.android.com/guide/topics/resources/multilingual-support

using zh, those that has traditional get simplified instead of English which is probably a good thing
But as mixing traditional and simplified will likely look weird it may be better to keep zh-CN in Transifex

This can be changed (as is done for sv-SE in Transifex and sv in RU).

So unless you have other suggestions @chenzaichun I will do the following:

• Squash and rebase
• remove 'zh'
• Push zh-CN to Transifex

[chenzaichun]

@gerhardol sure, I think keep zh-CN is acceptable right now. I'll add translation for traditional chinese later. Thanls.

Translations pushed: https://www.transifex.com/runner-up/runner-up-android/language/zh_CN/

There are a few new strings to translate

I pushed a cleaned up commit to https://github.com/gerhardol/runnerup/tree/chenzaichun/chinese-support
Either reset your change to the latest commit, or I will open a separate PR (I cannot push to this PR)

[chenzaichun]

@gerhardol I had added missing translation in transifex, but I don't know what can I do next. Could you please help? Should I add the missing translation to the xml and push to the PR again?

[gerhardol]

Register in transifex and up date there

[chenzaichun]

already updated in transifex. :)

[gerhardol]

Can you make sure I can push to the branch (allow maintainers), then I will pull from Transifex to my squashed branch, push to this branch and merge

[chenzaichun]

@gerhardol I reset the branch to the commit you squashed, and you could merge and push to this branch. Thanks.

[gerhardol]

Thanks

I did a fixup to Transifex zh for two arrays, pulled the updates in another PR (also merged)

[chenzaichun]

Thanks. :)
