Customizable calendar in Android with animations and range selection

rangecalendar's Issues

Future goals

• Allow cell to have different width and height
• Introduce non-consecutive ranges
• Allow to change text alignment in a cell.
• Connectable transitions (low priority)

Add better support for first day of week different than Monday

Currently, the support seems to be flaky. That needs to be fixed.

Class referenced in the layout file, com.github.pelmenstar1.RangeCalendarView, was not found in the project or the libraries

Hi, I'm trying this library but getting error while adding the calendar in XML. I'm also getting this message after sync

Move logic relating to drawing weekday row out of RangeCalendarGridView

Add better mechanism for observing date, time zone changes

At the moment, the library offers a pretty simple mechanism to do that through BroadcastReceiver. When the view is attached to the screen it's enabled, when detached - disabled. It'd better if the library offers a better way to do it.

Move the logic out of the RangeCalendarView and disable the feature by default, because registering BroadcastReceiver and processing notifications about changes is not cheap. Instead, do it through a manager-like class that will do the following:
a) be Lifecycle-aware, so we won't constantly de/register the BroadcastReceiver when the view is on/off the screen. Anyway, there should be a way not to use Lifecycle, instead, manually un/register the BroadcastReceiver.
b) provide a way to enable/disable the observation of some properties (like observe time zone changes but not date ones)

Meanwhile, the RangeCalendarView should have a public API that would notify the calendar about these changes.

Allow cell to have different width and height

It'd be useful in some cases. Also, the library will be more flexible.

Allow ranges with skipped cells

These ranges are like [1; 4] ∪ [6; 7], so that there is no 5 cell in the range

This will be a completely different model than simple ranges so fast week selection will likely be disallowed.

Allow to disable animation for selections that come from user actions

Now there's only a way to disable it when you're selecting it through the dedicated method but not when the user is requesting it through gestures

Add ability to create transitions that can be merged with other transition

For example, we select a cell on the row (cell row animation) and fast-select a week while the previous animation is not ended. In theory, if we can capture the current position of a cell, we can merge these two animations, so that a transition will be seamless.

React to configuration changes

At the moment, the library does nothing on configuration changes. Instead, we could update things based on it (like locale). Of course, it will only work if the host activity is not recreated on config changes.
