PyBitmessage(Android)
This sample aims to be as close to a real world example of a mobile. It has a more refined design and also provides a practical example of how a mobile app would interact and communicate with its adresses.
Steps for trying out this sample:
Compile and install the mobile app onto your mobile device or emulator.
Getting Started
This sample uses the kivy as Kivy is an open source, cross-platform Python framework for the development of applications that make use of innovative, multi-touch user interfaces. The aim is to allow for quick and easy interaction design and rapid prototyping whilst making your code reusable and deployable.
Kivy is written in Python and Cython, supports various input devices and has an extensive widget library. With the same codebase, you can target Windows, OS X, Linux, Android and iOS. All Kivy widgets are built with multitouch support.
Kivy in support take Buildozer which is a tool that automates the entire build process. It downloads and sets up all the prequisites for python-for-android, including the android SDK and NDK, then builds an apk that can be automatically pushed to the device.
Buildozer currently works only in Linux, and is an alpha release, but it already works well and can significantly simplify the apk build.
To build this project, use the "Buildozer android release deploy run" command or use.
Buildozer ue=sed for creating application packages easily.The goal is to have one "buildozer.spec" file in your app directory, describing your application requirements and settings such as title, icon, included modules etc. Buildozer will use that spec to create a package for Android, iOS, Windows, OSX and/or Linux.
Installing Requirements
You can create a package for android using the python-for-android project as with using the Buildozer tool to automate the entire process. You can also see Packaging your application for the Kivy Launcher to run kivy programs without compiling them.
You can get buildozer at https://github.com/kivy/buildozer or you can directly install using pip install buildozer
This will install buildozer in your system. Afterwards, navigate to your project directory and run:
buildozer init
This creates a buildozer.spec file controlling your build configuration. You should edit it appropriately with your app name etc. You can set variables to control most or all of the parameters passed to python-for-android.
Install buildozer’s dependencies.
Finally, plug in your android device and run:
buildozer android debug deploy run >> To build, push and automatically run the apk on your device. Here we used debug as tested in debug mode for now.

Bottom Sheets
=============
`Material Design spec Bottom Sheets page <http://www.google.com/design/spec/components/bottom-sheets.html>`_
In this module there's the :class:`MDBottomSheet` class which will let you implement your own Material Design Bottom Sheets, and there are two classes called :class:`MDListBottomSheet` and :class:`MDGridBottomSheet` implementing the ones mentioned in the spec.
Examples
--------
.. note::
These widgets are designed to be called from Python code only.
For :class:`MDListBottomSheet`:
.. code-block:: python
bs = MDListBottomSheet()
bs.add_item("Here's an item with text only", lambda x: x)
bs.add_item("Here's an item with an icon", lambda x: x, icon='md-cast')
bs.add_item("Here's another!", lambda x: x, icon='md-nfc')
bs.open()
For :class:`MDListBottomSheet`:
.. code-block:: python
bs = MDGridBottomSheet()
bs.add_item("Facebook", lambda x: x, icon_src='./assets/facebook-box.png')
bs.add_item("YouTube", lambda x: x, icon_src='./assets/youtube-play.png')
bs.add_item("Twitter", lambda x: x, icon_src='./assets/twitter.png')
bs.add_item("Da Cloud", lambda x: x, icon_src='./assets/cloud-upload.png')
bs.add_item("Camera", lambda x: x, icon_src='./assets/camera.png')
bs.open()

Lists
=====
`Material Design spec, Lists page <https://www.google.com/design/spec/components/lists.html>`_
`Material Design spec, Lists: Controls page <https://www.google.com/design/spec/components/lists-controls.html>`_
The class :class:`MDList` in combination with a ListItem like
:class:`OneLineListItem` will create a list that expands as items are added to
it, working nicely with Kivy's :class:`~kivy.uix.scrollview.ScrollView`.
Simple examples
---------------
Kv Lang:
.. code-block:: python
ScrollView:
do_scroll_x: False # Important for MD compliance
MDList:
OneLineListItem:
text: "Single-line item"
TwoLineListItem:
text: "Two-line item"
secondary_text: "Secondary text here"
ThreeLineListItem:
text: "Three-line item"
secondary_text: "This is a multi-line label where you can fit more text than usual"
Python:
.. code-block:: python
# Sets up ScrollView with MDList, as normally used in Android:
sv = ScrollView()
ml = MDList()
sv.add_widget(ml)
contacts = ["Paula", "John", "Kate", "Vlad"]
for c in contacts:
ml.add_widget(
OneLineListItem(
text=c
)
)
Advanced usage
--------------
Due to the variety in sizes and controls in the MD spec, this module suffers
from a certain level of complexity to keep the widgets compliant, flexible
and performant.
For this KivyMD provides ListItems that try to cover the most common usecases,
when those are insufficient, there's a base class called :class:`ListItem`
which you can use to create your own ListItems. This documentation will only
cover the provided ones, for custom implementations please refer to this
module's source code.
Text only ListItems
-------------------
- :class:`~OneLineListItem`
- :class:`~TwoLineListItem`
- :class:`~ThreeLineListItem`
These are the simplest ones. The :attr:`~ListItem.text` attribute changes the
text in the most prominent line, while :attr:`~ListItem.secondary_text`
changes the second and third line.
If there are only two lines, :attr:`~ListItem.secondary_text` will shorten
the text to fit in case it is too long; if a third line is available, it will
instead wrap the text to make use of it.
ListItems with widget containers
--------------------------------
- :class:`~OneLineAvatarListItem`
- :class:`~TwoLineAvatarListItem`
- :class:`~ThreeLineAvatarListItem`
- :class:`~OneLineIconListItem`
- :class:`~TwoLineIconListItem`
- :class:`~ThreeLineIconListItem`
- :class:`~OneLineAvatarIconListItem`
- :class:`~TwoLineAvatarIconListItem`
- :class:`~ThreeLineAvatarIconListItem`
These widgets will take other widgets that inherit from :class:`~ILeftBody`,
:class:`ILeftBodyTouch`, :class:`~IRightBody` or :class:`~IRightBodyTouch` and
put them in their corresponding container.
As the name implies, :class:`~ILeftBody` and :class:`~IRightBody` will signal
that the widget goes into the left or right container, respectively.
:class:`~ILeftBodyTouch` and :class:`~IRightBodyTouch` do the same thing,
except these widgets will also receive touch events that occur within their
surfaces.
Python example:
.. code-block:: python
class ContactPhoto(ILeftBody, AsyncImage):
pass
class MessageButton(IRightBodyTouch, MDIconButton):
phone_number = StringProperty()
def on_release(self):
# sample code:
Dialer.send_sms(phone_number, "Hey! What's up?")
pass
# Sets up ScrollView with MDList, as normally used in Android:
sv = ScrollView()
ml = MDList()
sv.add_widget(ml)
contacts = [
["Annie", "555-24235", "http://myphotos.com/annie.png"],
["Bob", "555-15423", "http://myphotos.com/bob.png"],
["Claire", "555-66098", "http://myphotos.com/claire.png"]
]
for c in contacts:
item = TwoLineAvatarIconListItem(
text=c[0],
secondary_text=c[1]
)
item.add_widget(ContactPhoto(source=c[2]))
item.add_widget(MessageButton(phone_number=c[1])
ml.add_widget(item)

CircularLayout
==============
CircularLayout is a special layout that places widgets around a circle.
See the widget's documentation and the example for more information.
![Screenshot](screenshot.png)
size_hint
---------
size_hint_x is used as an angle-quota hint (widget with higher
size_hint_x will be farther from each other, and viceversa), while
size_hint_y is used as a widget size hint (widgets with a higher size
hint will be bigger).size_hint_x cannot be None.
Widgets are all squares, unless you set size_hint_y to None (in that
case you'll be able to specify your own size), and their size is the
difference between the outer and the inner circle's radii. To make the
widgets bigger you can just decrease inner_radius_hint.

Circular Date & Time Picker for Kivy
====================================
(currently only time, date coming soon)
Based on [CircularLayout](https://github.com/kivy-garden/garden.circularlayout).
The main aim is to provide a date and time selector similar to the
one found in Android KitKat+.
![Screenshot](screenshot.png)
Simple usage
------------
Import the widget with
```python
from kivy.garden.circulardatetimepicker import CircularTimePicker
```
then use it! That's it!
```python
c = CircularTimePicker()
c.bind(time=self.set_time)
root.add_widget(c)
```
in Kv language:
```
<TimeChooserPopup@Popup>:
BoxLayout:
orientation: "vertical"
CircularTimePicker
Button:
text: "Dismiss"
size_hint_y: None
height: "40dp"
on_release: root.dismiss()
