    <p>Following is an example of Android with sqlite. It is very useful for beginner. Example contains ListActivity instead if Spinner. Just learn the example properly and you can make changes according your requirements. </p> <pre><code>public class CRUDonDB extends ListActivity { private final String SAMPLE_DB_NAME = "myFriendsDb"; private final String SAMPLE_TABLE_NAME = "friends"; /** Called when the activity is first created. */ @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); ArrayList&lt;String&gt; results = new ArrayList&lt;String&gt;(); SQLiteDatabase sampleDB = null; try { sampleDB = this.openOrCreateDatabase(SAMPLE_DB_NAME, MODE_PRIVATE, null); sampleDB.execSQL("CREATE TABLE IF NOT EXISTS " + SAMPLE_TABLE_NAME + " (LastName VARCHAR, FirstName VARCHAR," + " Country VARCHAR, Age INT(3));"); sampleDB.execSQL("INSERT INTO " + SAMPLE_TABLE_NAME + " Values ('Makam','Sai Geetha','India',25);"); sampleDB.execSQL("INSERT INTO " + SAMPLE_TABLE_NAME + " Values ('Chittur','Raman','India',25);"); sampleDB.execSQL("INSERT INTO " + SAMPLE_TABLE_NAME + " Values ('Solutions','Collabera','India',20);"); Cursor c = sampleDB.rawQuery("SELECT FirstName, Age FROM " + SAMPLE_TABLE_NAME + " where Age &gt; 10 LIMIT 5", null); if (c != null ) { if (c.moveToFirst()) { do { String firstName = c.getString(c.getColumnIndex("FirstName")); int age = c.getInt(c.getColumnIndex("Age")); results.add("" + firstName + ",Age: " + age); }while (c.moveToNext()); } } this.setListAdapter(new ArrayAdapter&lt;String&gt;(this, android.R.layout.simple_list_item_1,results)); } catch (SQLiteException se ) { Log.e(getClass().getSimpleName(), "Could not create or Open the database"); } finally { if (sampleDB != null) sampleDB.execSQL("DELETE FROM " + SAMPLE_TABLE_NAME); sampleDB.close(); } } } </code></pre> <p>Also have a look at this <a href="http://www.mydoople.com/android-spinner-example" rel="nofollow">Spinner Example</a>.</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
