Many of our articles will have code listings, they will appear like this piece of code here (handling a button click in an Android App using an anonymous inner class).

[code lang=”java”]
public class main extends Activity {
@Override
 public void onCreate(Bundle savedInstanceState) {
  super.onCreate(savedInstanceState);
 setContentView(R.layout.main);
findViewById(R.id.button1).setOnClickListener(new OnClickListener(){
public void onClick(View arg0) {
  Button btn = (Button)arg0;
 TextView tv = (TextView) findViewById(R.id.textview1);
 tv.setText("You pressed " + btn.getText());
}
});
}
}
[/code]

When you move the pointer over the code a toolbar appears, use these icons to copy the code:

Use the copy to clipboard icon to copy the code to the clipboard. On some operating systems it will not copy the line breaks correctly. Use the view source option.

Or:

The view source icon displays the raw source code, on some operating systems this may be better for copying the code, click the icon, select the code in the box that appears and use the context menu to copy it.

Once the code is copied it can be pasted into your own files.
