This merges the "Layouts" option with the "Custom layout" option.
A custom layout becomes an item in the "Layouts" list among the other
layouts. It's possible to add several custom layouts.
Selecting the "Custom layout" item in the list opens a second dialog for
entering the layout description.
Layouts are serialized as JSON object and are decoded solely in the
LayoutsPreference class.
The two layout selection options are replaced by a ListGroupPreference
that allow to enter an arbitrary amount of layouts.
The "switch_second" and "switch_second_back" keys are replaced by
"switch_forward" and "switch_backward", which allow to cycle through the
selected layouts in two directions.
Layouts are changed to place these two key on the space bar.
The backward key is not shown if there's only two layouts.
* Add section mark as an extra key in QWERTY-like layouts that don't have it already
* Add dagger (also double dagger) as an extra key in QWERTY-like layouts
This is a new section in the extra keys option that allows to enter
arbitrary strings which are then added to the keyboard.
A new string is needed for the title of the section, Android's icons and
strings are used as much as possible to avoid adding more strings.
Keys are stored in the preferences as a JSON array of strings.
The current approach is hard to maintain, for example the last key
"autofill" was not displayed.
This implements a PreferenceGroup that contains the check boxes for
every extra keys without involving listing the preferences in
settings.xml.
A custom layout is used to remove the 'title' text view.
The list of extra keys is moved into the new class.
'ExtraKeyCheckBoxPreference' becomes a nested class.
This function is no longer an hardcoded list of layout ids. It's
replaced by a linear scan of the previously generated array and a new
corresponding array of resource ids.
`gen_layouts.py` lists the layouts in `res/xml` and generate the
`pref_layout_values` and `pref_layout_entries` arrays into
`res/values/layouts.xml`.
These arrays are hard to maintain as the order has to match, which is
fragile.
This relies on every layouts having a `name` attribute.
Added Romanian characters to the keyboard layout and changed the positioning
corner for the secondary characters that were conflicting with the
newly-introduced romanian characters
Added Romanian translations
