The symbols are now smaller for Shift, Space, Backspace, Delete and
some keys on the bottom row.
The previous rule was to make the text smaller for symbols made of
several characters.
This is changed to a flag approach.
For the Dark and Light theme. At the same time, use only "web safe
colors" to have nice round numbers and ensure enough contrasts between
colors.
The background color is kept at the previous value, there's not enough
contrast between the background and the keys but that's better than a
solid black background.
Use the height of the row currently being rendered instead of the base
row size.
Concretely, the bottom row is slightly smaller and will get slightly
smaller text.
Also:
- Rewrite the label rendering code
- Render labels at the middle of the key (was slightly off)
Instead of a fixed size that don't work at all for bigger screens.
Other tweaks:
- Use the value-land dimens to vary 'extra_horizontal_margin'
- Move label size to Config, because it can change at runtime (rotation)
- Slightly decrease the size of "long" symbols
`res/xml/qwerty_lv.xml` was updated to add the missing full stop
character (`.`) as it got lost when the bottom row was moved to a
separate XML `res/xml/bottom_row.xml` as it was placed on the
arrows key.
Additionally `?` was relocated, giving its place to the full stop.
Before sending a key event while modifiers are active, send events for
the modifier keys.
Some applications don't look at the "metaState" flags but instead keep
track of the up and down events for the modifiers.
For example, the basic text views that are in every applications
correctly handle the "metaState" flags except for one binding:
Selecting text with the arrows while pressing shift.
Change the formula: don't use an external constant, add a state.
It's now the ratio between where the finger is at the first repeat and
where it is now.
Keep the repeat going when swiping into an other key. Currently only for
arrows: It's now possible to go from an arrow to an other without
waiting again for the key repeat timeout.
The backspace and delete keys don't work well with this.
Show these characters only for users that have the corresponding locale
installed (a supported eu language for €, en-GB for £).
Add these characters to most layouts.
Depending on the pixel density isn't ideal for a keyboard, which would
render differently depending on the "scaling" accessibility option.
Landscape mode needs a special values. At the same time, increase the
horizontal margin when landscape.
MIUI inverts the colors of the app it thinks doesn't implement dark
themes correctly. Also, it inverts the colors in the dumbest possible
way: it doesn't invert all the colors the same way.
It thinks that presumably because I don't use the Material base themes.
- Add the umlauts back.
- Remove the accents. QWERTZ changes from "programming layout" to
"localized layout".
- Move the '?' away from the edge of the screen.
Add a new boolean parameter "edgekeys" for defining keys that have the
additional (swipe) keys on the edges (top, right, left, bottom) instead
of at the corners (top left, top right, bottom left, bottom right).
Currently using the diamond symbol like the history meta key: https://en.wikipedia.org/wiki/Meta_key
However, this key is actually interpreted as the Super/Windows key but
Android calls it "meta" internally.
There were two problems:
- The Action key was swapped when it shouldn't be. The flag
'IME_FLAG_NO_ENTER_ACTION' wasn't interpreted correctly for inputs
that specified both an action and this flag.
- The value 'IME_ACTION_UNSPECIFIED' should remove the Action key.
