  46. 46. Exercise 1 Linear Layout
  47. 47. 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.
  48. 48. 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".

  71. 71. Exercise 1 Relative Layout
  72. 72. Relative Layout - A layout is a view group that displays child views in relative positions.
  73. 73. 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.

  83. 83. Exercise 4 Table Layout
  84. 84. 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.
  85. 85. Task 1: Create XML Layout - Right click on the res/layout folder.
  86. 86. Task 2: Defining an XML Layout - Enter code: https://gist.github.com/leonguyen/5325531

  97. 97. Exercise 1 List View
  98. 98. 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.
  99. 99. 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.

  125. 125. Task 4: Execute your program - Choose "Run As" > "Android Application"
  126. 126. 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.
  127. 127. 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.

  161. 161. 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.

  212. 212. Lab 03.3 Internal.External
  213. 213. Outline - Internal.External with File - External with SQLite
  214. 214. 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.

  225. 225. Lab 04.1 Intent
  226. 226. Outline - Intent - Intent Explicit
  227. 227. 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.
  228. 228. 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.

  240. 240. Outline - Content Provider - Content Provider with Contact, Call Log Picker - Content Provider with Settings - Content Provider Custom
  241. 241. 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.
  242. 242. 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.
