You can specify the layout direction with the android:orientation attribute. LinearLayout has one goal in life: lay out children in a single row or column (depending on if its android:orientation is horizontal or vertical).

From a programming point of view, an activity is a class that extends the Activity class. Unlike other systems in which a program contains several windows displayed simultaneously, in Android, the screen is always occupied by a single window. Moreover, windows are connected by the simple fact that a window generates several windows. The window that appears on the screen when the application is started is considered the main… text/html 2021-04-04T19:47:14+03:00 http://ocw.cs.pub.ro/courses/dapm/laboratoare/03?rev=1617554834&do=diff Lab 05 - Intents Intents An Intent is a messaging object you can use to request an action from another app component. Although intents facilitate communication between components in several ways, there are three fundamental use cases: - Starting an activity - Starting a service - Delivering a broadcast An Activity represents a single screen in an app. You can start a new instance of an Activity by passing an Intent to startActivity(). The Intent describes the activity to start and carr… text/html 2020-02-28T17:00:08+03:00 http://ocw.cs.pub.ro/courses/dapm/laboratoare/04?rev=1582902008&do=diff Laboratorul 04. Grid Layout The grid is composed of a set of infinitely thin lines that separate the viewing area into cells. Throughout the API, grid lines are referenced by grid indices. A grid with N columns has N + 1 grid indices that run from 0 through N inclusive. Regardless of how GridLayout is configured, grid index 0 is fixed to the leading edge of the container and grid index N is fixed to its trailing edge (after padding is taken into account). text/html 2021-04-10T21:03:00+03:00 http://ocw.cs.pub.ro/courses/dapm/laboratoare/05?rev=1618077780&do=diff Lab 06 - Lists LISTS In android, an adapter is a bridge between UI component and data source that helps us to fill data in the UI component. It holds the data and send the data to adapter view then view can takes the data from the adapter view and shows the data on different views like as list view, grid view, spinner etc BaseAdapter methods: 1. getCount(): The getCount() function returns the total number of items to be displayed in a list.

One of this way is called Shared Preferences. Shared Preferences allow you to save and retrieve data in the form of key,value pair. In order to use shared preferences, you have to call a method getSharedPreferences() that returns a SharedPreference instance pointing to the file that contains the values of preferences. Initialization Application shared preferences can be fetched u… text/html 2020-03-30T00:38:45+03:00 http://ocw.cs.pub.ro/courses/dapm/laboratoare/07?rev=1585517925&do=diff Laboratorul 07. Fragments A fragment is an independent Android component which can be used by an activity. A fragment encapsulates functionality so that it is easier to reuse within activities and layouts. A fragment runs in the context of an activity, but has its own life cycle and typically its own user interface. It is also possible to define fragments without an user interface, i.e., headless fragments. One difference when creating a Fragment is that you must use the onCreateView() cal… text/html 2020-04-13T13:00:22+03:00 http://ocw.cs.pub.ro/courses/dapm/laboratoare/08?rev=1586772022&do=diff Laboratorul 08. SQLite and Firebase SQLite is an open-source relational database i.e. used to perform database operations on android devices such as storing, manipulating or retrieving persistent data from the database. SQLite is a local database on Android device (data stored/processed on a device) with SQL interface. So, there is no need to perform any database setup or administration task.
