This allows to use modifiers in combination with other inputs like a
mouse click, for example under termux-x11.
The key down event and notification about modifiers changing are sent
down to KeyEventHandler. A mutable state remember for which modifier
down events have been sent.
When pressing down a modifier with one finger and typing with the
other, it might appear that the modifier is released after the first
time an other key is pressed and then pressed and released for the
following keys.
This prevents unintentionally type two modified keys instead of one
when the second key is pressed while the other is not yet released.
This reverts commits ef03dfed5c and
ff01678ba6.
The "vibration duration" slider is bought back.
The "vibration enabled" option is replaced by "custom vibration", which switch between the system haptic feedback or the custom vibration.
The slider is greyed when "custom vibration" is unchecked and is
allowed to have a value of 0 to disable vibrations within the app.
The intermediate values "light", "medium" and "strong" are removed and
no migration of the setting is made.
`KeyboardData.getKeys()` now returns a map of the keys present on the
layout to their position. Positions are the row, column and swipe
direction.
The computed map is cached in the KeyboardData object as it might be
accessed later by `findKeyWithValue`, which now do less work.
Several non-string keys can have a large label that shouldn't be elided,
for example ctrl, meta, send.
Also, change the cutoff to 3 characters as labels are easily colliding.
The newer haptic feedback API that is used instead of the vibrator
service since ef03dfe doesn't work for everyone.
The new vibration option allow to choose both the newer API ("system")
and the older API ("strong", "medium", "light").
Specify the behavior of shift for a layout. This is intended for locales
that use the same alphabet but have different capital letters (eg.
Bengali).
The modmap is defined like this:
<keyboard>
<modmap>
<shift a="a" b="A"/>
</modmap>
</keyboard>
'Keyboard.Key' now contains an array of size 9, giving each keyvalue an
index. The algorithm for finding the nearest key during a swipe now
needs 16 segments, which are now calculated as an angle.
The algorithm does one more interation instead of 2 more, slightly
reducing the sensitivity of corner values. The 'getAtDirection' function
is moved into the Pointers class to clearly separate the two systems.
The 'edgekey' attribute is now obsolete but is kept for compatibility.
The flag is removed internally, key index are simply translated.
Similarly, the 'slider' attribute now act on keys at index 5 and 6
instead of 2 and 3.
The 'keysHeight' field needs to be updated. As this class is not
intended to be mutable, copy the list of rows and call the constructor.
Also remove an unecessary component of the keyboard height calculation.
* Add option for keyboard opacity (transparency). Keyboard background, keys and pressed keys can be adjusted separately.
* Make the borders transparent as well
* Moved setAlphas outside drawKeyFrame to top of onDraw method
Themes can define the color of each borders independently. Every borders
must have the same width for now. It's possible to set a different width
when the key is activated, thought this is only used to remove borders.
The 4 themes are updated to take advantage of borders.
Remove the code dealing with InputMethodConnection from 'Keyboard2' and
move it into 'KeyEventHandler', where more editing actions can now be
implemented.
Autocapitalisation is also moved, the IReceiver interface is simplified.
The key enable caps lock immediately. It does nothing if caps lock is
already enabled.
It is not present on the keyboard by default but a place is defined on
every layout, top-right of the shift key. It can be enabled in the
settings.
The icon is from materialdesignicons.com.
Modifiers can be locked with a long press. The key repeat mechanism is re-used
and the press timeout is the same.
Every modifiers can be locked that way, not only the "lockable" ones.
The previous behavior can be enabled in the settings (for shift only)
but the default is changed.
Keep track of end-of-sentence characters while typing and automatically
enable shift when appropriate.
The last few characters just before the cursor need to be queried in
some cases: Begin of input, cursor has moved or text is deleted.
This might have a performance cost.
This normally only enable shift but it also needs to disable shift when
the cursor moves.
Bring back the "Vibration" option.
The duration option isn't added back because the vibration settings are
still handled by Android. In fact, the option has no effect if the
vibration are disabled in the system settings.
This partially reverts commit ef03dfed5c.
The "loc " prefix for predefining a place for an "extra key" was broken
since 31d6a70.
The FLAG_LOCALIZED flag cannot be used anymore, as adding it to any key
would turn it into a different key that wouldn't be recognized by parts
of the code comparing the keys (placing the extra keys).
Add an other layer in KeyboardData to store such informations.
The meaning of the public fields of KeyValue was quite complicated and
not handled consistently accross the app.
Make these fields private and add a more abstract API on top.
The meaning of these fields changed recently and it wasn't an easy
change. I plan on making more changes in the future.
There was no free bits left to add new modifiers. Instead of increasing
the width of the 'flags' field, refactor the way modifiers are
represented and used.
Modifers are now represented as independent values and stored in the
'code' field. A flag is added to distinguish between modifiers and keys
with a key event.
The most notable change is that modifiers can no longer be or-ed into a
single value but have to be represented as an array.
The "closest key" logic must be careful not to reveal keys removed by a
modifier.
Must check [_handler.onPointerSwipe] for every candidate values.
[selected_value] is changed back to [selected_direction].
This adds a new bug: When the direction change, the selected value might
not change but a vibration will be triggered anyway.
Since SDK 21, applications can set the background color of the
navigation bar. This is normally simply an item in a theme but it is
more complicated for keyboards.
Modifiers can temporarily remove a key from the layout by returning
'null'.
Make sure pointer handling code handle these modified keys gracefully
and doesn't trigger a key event and a vibration for the removed key.
Handling this event is part of the API but was never done. This caused
unstoppable key-repeat.
This event isn't common, the only way I found on Android 10 is to switch
to the emoji keyboard while holding a key. Some apps might cause this
event more often.
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.
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
