Linear Layout
- A layout is a view group that aligns all children in a single
direction, vertically or horizontally.
- All children of a LinearLayout are stacked one after the other,
so a vertical list will only have one child per row, no matter how
wide they are, and a horizontal list will only be one row high (the
height of the tallest child, plus padding). A LinearLayout respects
margins between children and the gravity (right, center, or left
alignment) of each child.

Layout weight
- To create a linear layout in which each child uses the same
amount of space on the screen, set the android:layout_height of
each view to "0dp" (for a vertical layout) or the android:
layout_width of each view to "0dp" (for a horizontal layout). Then
set the android:layout_weight of each view to "1".

Task 1: Create XML Layout

- Table Layout - Weather
- Scroll View

Relative Layout
- A layout is a view group that displays child views in relative
positions.

Positioning Views
- Some of the many layout properties available to views in a RelativeLayout
include:
android:layout_alignParentTop
If "true", makes the top edge of this view match the top edge of the parent.
android:layout_centerVertical
If "true", centers this child vertically within its parent.
android:layout_below
Positions the top edge of this view below the view specified with a resource ID.
android:layout_toRightOf
Positions the left edge of this view to the right of the view specified with a
resource ID.
These are just a few examples. All layout attributes are documented at
RelativeLayout.LayoutParams.

Exercise 2

Relative Layout - Reminder

Exercise 3

Relative Layout - Work

Table Layout
- A layout that arranges its children into rows and columns. A TableLayout
consists of a number of TableRow objects, each defining a row (actually, you
can have other children, which will be explained below). TableLayout
containers do not display border lines for their rows, columns, or cells. Each
row has zero or more cells; each cell can hold one View object. The table has
as many columns as the row with the most cells. A table can leave cells empty.
Cells can span columns, as they can in HTML.

Exercise 5

- List View
- List View with Custom Layout
- List View with Context Menu
- List View with Custom Adapter
- List View with Custom ArrayList
- List View with Activity
- List View with Activity and Custom Main Layout
- List View with Thread

List View
- A view group that displays a list of scrollable items. The list
items are automatically inserted to the list using an Adapter that
pulls content from a source such as an array or database query
and converts each item result into a view that's placed into the
list.

ArrayAdapter
- Use this adapter when your data source is an array. By default,
ArrayAdapter creates a view for each array item by calling
toString() on each item and placing the contents in a TextView.

Task 1: Create ListView Activity

Exercise 2

List View with Custom Layout

Exercise 3

List View with Context Menu

Task 3: Create List View Activity

Loader
- Using a CursorLoader is the standard way to query a Cursor as
an asynchronous task in order to avoid blocking your app's main
thread with the query.
- When the CursorLoader receives the Cursor result, the
LoaderCallbacks receives a callback to onLoadFinished(), which
is where you update your Adapter with the new Cursor and the
list view then displays the results.

SimpleCursorAdapter
- Use this adapter when your data comes from a Cursor. When
using SimpleCursorAdapter, you must specify a layout to use for
each row in the Cursor and which columns in the Cursor should
be inserted into which views of the layout.

Task 1: Create Dialog XML Layout
- Right click on the res/menu folder.

Task 4: Add Option Menu

Outline

- Right click on the res/layout folder.

Task 3: Create Custom Dialog program

Widget
- App Widgets are miniature application views that can be
embedded in other applications (such as the Home screen) and
receive periodic updates.
- To create an App Widget, you need the following:
+ AppWidgetProviderInfo object
Describes the metadata for an App Widget, such as the App
Widget's layout, update frequency, and the AppWidgetProvider
class.
+ AppWidgetProvider class implementation
Defines the basic methods that allow you to programmatically
interface with the App Widget, based on broadcast events.
+ View layout
Defines the initial layout for the App Widget, defined in XML.

Outline
- Shared Preferences
- Shared Preferences - Preference Activity

Shared Preferences
- The SharedPreferences class provides a general framework
that allows you to save and retrieve persistent key-value pairs of
primitive data types. You can use SharedPreferences to save
any primitive data: booleans, floats, ints, longs, and strings. This
data will persist across user sessions (even if your application is
killed).
+ getSharedPreferences() - Use this if you need multiple
preferences files identified by name, which you specify with the
first parameter.
+ getPreferences() - Use this if you need only one preferences
file for your Activity. Because this will be the only preferences file
for your Activity, you don't supply a name.

- Internal.External with File
- External with SQLite

Storage
- Internal storage are private to your application and other
applications cannot access them (nor can the user). When the
user uninstalls your application, these files are removed.
- External storage such as SD card can also store application
data, there's no security enforced upon files you save to the
external storage. All applications can read and write files placed
on the external storage and the user can remove them.

Outline
- Intent
- Intent Explicit

Intent
- Intents are system messages, running around the inside of the
device, notifying applications of various events, from hardware state
changes (e.g.,an SD card was inserted), to incoming data (e.g., an
SMS message arrived),to application events (e.g., your activity was
launched from the device’s main menu).
- Not only can you respond to intents, but you can create your own, to
launch other activities, or to let you know when specific situations arise
(e.g., raise such-and-so intent when the user click this button).
- Intents are asynchronous messages which allow Android
components to request functionality from other components of the
Android system. For example an Activity can send an Intents to the
Android system which starts another Activity.
- Three of the core components of an application — activities, services,
and broadcast receivers — are activated through messages, called
intents.

Explicit and Implicit
- Explicit intents designate the target component by its name
(the component name field, mentioned earlier, has a value set).
Since component names would generally not be known to
developers of other applications, explicit intents are typically
used for application-internal messages.
- Implicit intents do not name a target (the field for the
component name is blank). Implicit intents are often used to
activate components in other applications.

- Content Provider with Contact, Call Log Picker

Content Provider
- ContentProvider manage access to a structured set of data. The main
methods are Query, Insert, Update and Delete.
- ContentResolver is a static proxy that communicates with a
ContentProvider to access its data, either from within the same
application or from another application.

Built-In Provider
- Android offers access to a wide range of system and user data using
ContentProviders.
- Browser – bookmarks and browser history (requires permission
READ_HISTORY_BOOKMARKS and/or
WRITE_HISTORY_BOOKMARKS).
- CallLog – recent calls made or received with the device.
- Contacts – detailed information from the user’s contact list, including
people, phones, photos & groups.
- MediaStore – contents of the user’s device: audio (albums, artists,
genres, playlists), images (including thumbnails) & video.
- Settings – system-wide device settings and preferences.
- UserDictionary – contents of the user-defined dictionary used for
predictive text input.
- Voicemail – history of voicemail messages.
