Hey Laura,

I know the feeling of just starting out. It's quite daunting, and especially all the code that drops in with onClickListener. Here's a quick guide for you:

// declare your button object (if it isn't already declared). For the findViewById - find the ID of the button in the layout file
Button myButton = (Button) findViewById(R.id.button2);

// declare and set your onClickListener to myButton
myButton.setOnClickListener(new View.OnClickListener() {

@Override
public void onClick(View v) {
  // Your code goes here! This happens when the user clicks on the button!
}
});

I hope this helps you out. I know the code is a bit daunting for the OnClickListener, but look closely and observe -

myButton.setOnClickListener( new View.OnClickListener()) {...

This single line of code declares your brand new onClickListener, and sets it to that button you declared.

A good rule of thumb to remember is whenever you use a "findViewById()" method, you use an ID that must correspond with an object in your layout.xml file. All beginner stuff, but solid basic skills make solid programmers.

Good luck! Hope this helps!

Ben
