On the android studio home you will need to create a new project


Name your project:


Usually i'd have my api level up to 4.4 kitkat but you can go ever low you want. lowest i would go wout be api 14 on 4.0.


Select blank activity and hit next


Hit next on this screen


If you are having trouble viewing the preview, select an api that suits you. In this case, api 21 fits my preview well


On the left you have all your project files, middle is usually where you write your code.
In layouts, you will have a design tab and a text tab at the bottom, you cans switch between each other



On our design tab you, you will have a visual studio/netbeans like gui designer where you can drag views onto the screen


What i want you to do is drag a button onto the screen and move the text to the center so you will have a better feel of how it operates. It takes a while to get use to.


Click on the click button and you will see properties on the bottom right. Give the button a custom text.


Scroll up and give the button an id, you will use that id in the code, also click on the TextView and give that an id called "textview"


Here we have the onCreate Method where we initialize our views and populate the activity activity


In this image we initialize out views, having out view global so it can be accessed anywhere within the class


Now here we implement an interface, hitting alt enter will solve your problems. When adding the interface, it implements the methods to override so you can use that for your view. In this case we will use OnClickListener for the button. Notice how we use "this", the reason we did that is because this class implements the method we will be overriding. Typically you would use the OnClick method this way but for speed you can test.


Run the app/emulator and see what you come up with, here we have our default untouched activity


Once clicked it will bring up a toast saying hello world as well as changing the text of the textview
