The user will learn how to add an OnClickListener to a button.
A computer System is required for this tutorial.
Java Software Development Kit(JDK) must be installed on your computer.
Get JDK here
Get Android Studio here
This is the first tutorial on Android App Development and so we will look at how to create a Button, a TextView and an EditText widget.
A button in general programming is a class which refers to a clickable component. In Android and most programming languages, buttons exist in various types.
Different types of Buttons include:
This tutorial will concern itself with Push Buttons.
Buttons can perform functions and can also perform no action.
Buttons when created can be associated with Listeners. Listeners make it possible for buttons to perform an action when clicked or when pressed.
In Android, the Listener interface associated with the click of a button is called an OnClick Listener and this has a method “OnClick” which must always be implemented.
TextView provides the user with the opportunity to view text. This text can also be edited. A programmer may choose to make text in a TextView editable or un-editable.
TextView can also serve as a text editor, e.g Notepad. The basic job of TextView is to display readable text on the screen.
EditText is an extension of TextView. This provides the user with the means to provide input to the program. EditText also allows the user to enter input in different text styles and fonts.
The primary job of EditText is to allow the user to enter input through keypad.
In this tutorial we will create these three components prompting the user to enter a name. When the user enters a name, the user clicks a button and a message is returned confirming the user’s actions.
This tutorial is done in assumption that the user followed previous Java programming tutorials and has general knowledge of programming terms.
When a new project is started, the project is devided into two sections; activity_main and MainActivity.
