Spinner in Android/Spinner Example/Simple Spinner Program

Spinner is a widget similar to a drop-down list for selecting items. 

Create an array of items to be  displayed

String androidphones[]={"Sony Ericson Xperia","Motorola Droid", "Samsung Galaxy","HTC Sensation","LG Nitro","Google Nexus"};

Add an array adapter to display the spinner

spinner.setAdapter(new ArrayAdapter<String>(this, android.R.layout.simple_spinner_item,androidphones));

In spite of android.R.layout.simple_spinner_item, you can also add

android.R.layout.simple_spinner_dropdown_item

                          or

android.R.layout.simple_dropdown_item_1line
