Unit Converter Description of some functions and terms

Splash Screen• Splash screen is an activity that will show for set time

when our app is starting and after set time period the user is redirected to application main screen or main activity.

Unit ConverterToast

• A toast provides simple feedback about an operation in a small popup. It only fills the amount of space required for the message and the current activity remains visible and interactive.

Spinners• Spinners provide a quick way to select one value from

a set. In the default state, a spinner shows its currently selected value. Touching the spinner displays a dropdown menu with all other available values, from which the user can select a new one.

Unit Converter Layout Resource File• A layout resource defines the architecture for the UI in

an Activity or a component of a UI.

Unit ConverterEditText

A EditText field allows the user to type text into our app. It can be either single line or multi-line. Touching a text field places the cursor and automatically displays the keyboard.

 

Unit ConverterOnCreate()

When the user selects our app icon from the Home screen, the system calls the onCreate() method for the activity in our app that we've declared to be the "launcher" (or "main") activity. This is the activity that serves as the main entry point to our app's user interface. It is called on initial creation of the fragment & non graphical initializations are done here. 

findViewById()• Android findViewById () is a very commonly used function,

located in the android.app.Activity package. This function is used to find a view that was identified by the id attribute from the XML that was processed in onCreate(Bundle) .
