Now lets move on to the MainActivity.java file to code the function of the button.įirst, we have to call our TextView and the Button. That is everything that needs to be done on the Xml file.

The id I used was ‘button’ to keep things simple. Also give the Button an id, you can do so by using the Attributes panel. Then constrain the button to the Layout using the Constrain in the Attributes panel. To create the button, click and drag the button on the the canvas using the “Button” tab that is provided in the palette panel. But for this example I will do it by using the Design function. Both can be located in the bottom left of the screen.

all of the layout customizing will be done with in this file.Ī button can be added in two ways, one is to actually code the button in the “Text” tab or by using the “Design” tab. You can name your project whatever you want it does not matter.Īfter the project has been created, we will start with the activity_main.xml tab. For this project I will use the Blank Activity. In this tutorial we will set up a Button that will display a message in a TextView.įirst, we need to create a new project.
