Toggle checkboxes in view mode

[stefan-niedermann]

After #422 it is now possible to implement support for toggling checkboxes in the view mode.

There is already commented code, that does not completely work.

Another attempt to finally get this feature in: Everybody, please help test toggling checkboxes.

I attached a build of the branch #651 so you can easily install and test it:

nextcloud-notes-toggle-checkboxes.apk.zip

I think, there might be one or two bugs left caused by RxMarkdown, which we didn't workaround yet, just post it in #651 and i will try to take care of them.

I just installed the build and tested it quickly. It seems to work fine on Android 9!
Although, I had to uninstall the FDroid version first (I guess because this is a debug version?).

The 3x2 single note widget doesn't seem to work, it just shows "Note not found (Notiz nicht gefunden)". Used to work before :( This might be a completely unrelated issue, though.

The only difference to the web version is that it doesn't toggle the strike-through effect, but thats okay imo.

Thanks a lot, great work! 👍

That's right, because the app signature is different for a released version.

Regarding the widget: i think it's unrelated, for me it works, but we can have a look after this has been merged
Please test as many scenarios as you can imagine (only checkboxes, mixed with headlines, items containing markdown, only one checkbox in the whole note, ...)
