Create new voice editor

[xSabrina]

Description

Closes #106

This merges implement a new version of the feature to create and save voice notes. It mainly adjusts the note cardViews (since voice notes contain a seekbar and a play/pause and stop button) and creates a voice note editor fragment containing just a record-by-on-click button.

Here are some details on the changes:

• A permission-request for recording audio has been added to the BookNotesView before opening the voice-note-editor, if the permission is not given yet. If you deny there is an alertDialog to inform the user why it is necessary (clicking ok is reopening the request, clicking on cancel is just canceling the voice-note-editor-opening).
• The new VoiceNoteEditorFragment has just one record-button and a help option in the options-menu (alert dialog at the moment - needs to be adjusted to the way we implement our help in our app in general). Clicking on the record-button will light up the button icon slightly and starts a ripple animation as indicator for recording. The record can be stopped either by clicking on the record-button again or leave the fragment (there is a toast as "note has been saved"-feedback).
• The note-cardView for our note-lists contains a voice-note related part now for handling the seekBar and play/pause and stop button, which is only shown if the note is one of the voice types. The seekBar of an item is usable as soon as the linked recording has been started at least (means: the item's play-button has to be used first) to avoid some bugs - this is indicated by the grayed out seekBar appearance. The item's stop-Button is also just usable if the linked recording has been played at least (so you can not stop any item's playing by pressing another one's stop-button).
• A custom SeekBarListener has been added to perform seekBar-features (means: scrolling through the recording by moving the thumb).
• Methods to fetch a path-string of a noteFile from the database in NoteModel and NoteDao have been added.
• Also adjusted the NoteRecyclerViewAdapter params to contain a NoteModel as well to perform database-related features (like playing notes etc.) (its methods have also been adjusted to perfom voice note-features of course).
• Voice note related play, pause and stop icons have been added.
• Voice note related string ressources and a library-key have been added.
• Added implementations for the seekbar and the ripple-animation to the build.gradle and cleaned it up as well (adjusted two implemenation version declarations).

I also did some general small note-related clean ups:

• Typos in the TextNoteEditorFragment have been fixed.
• A bug in editting TextNotes caused by a missing bookId (since the adapter is not longer handling Note-objects, but NoteItem-Objects) in the NoteItems has been fixed by adding a bookId-param to constructors.
• Unnecessary and legacy constructors have been removed from some NoteItem-classes.
• The note-type related microphone.png has been increased in size since it was the same size as the document.png, but had more margin.
• fragment_book_notes.xml has been cleaned up (e.g. replacing dp by sp-units for text-size declarations).

Affects

Mainly note-related features like the BookNotesView and the database as well, so @SarahKurek should take a look. Also this is just an basic design idea for the voice note features - there might be some things that need or could be adjusted, which @LuisMossburger should take note of.

Notes for Reviewer

Some suggestions for your testing:

• If you use the emulator: open your extended controls and activate the option "Virtual microphone uses host audio input" so you can use your PC microphone.
• Android only allows to ask a few times for a request by system. This means if the user denies the request a few times, android will not allow to ask for it again and the request will not be shown anymore and the voice notes can not be used.

Please review & comment/approve. Thanks!

The voice editor works pretty good and I'm excited to have this in the app! :)

Thanks, same here :)

Some suggestions for code refactoring, as well as the layout for the list item. Also, please use these icons for the text notes controls and the voice note editor. I probably need to create one for the list view myself.

I applied all of your suggestions, implemented your new icons and deleted the old ones - please have another look :)

[xSabrina]

Hey! Thanks for implementing the suggestions. However, the layout in the list view still seems to cause problems (see screenshot). If you want, I can have another look and try to fix this tomorrow..

I see - that would be cool actually since the layout looks fine on my devices it is hard to check if the changes fixed it. The layout on your screenshot looks strange however since the voice elements should be constrainted right and next to each other now.

Hey! I made some adjustments and think the layout works properly now. Basically, I wrapped the whole list item in a ConstraintLayout and added constrainedWidth="true" to make it resizeable based on the surroundings. I also adjusted the voice editor button to make it fit with the rest of the apps design. Please have a look and re-request my feedback if you agree, so I can approve :)

Also, for me the Toast after creating a voice note is not showing up anymore, is that desired behaviour?

Hey, thanks for your effort! I see why this is solving the issue.

Ah, thank you - that is much better!

The toast works properly for me:

But there was a time after our first bigger design rework when all of my toasts did not show up anymore. After wiping and reinstalling toasts worked again - maybe this might solve your problem as well.
