<p>Here is a sample code which depicts the usage of spinner and action performed when spinner item is selected</p> <pre><code>import android.os.Bundle; import android.app.Activity; import android.view.View; import android.widget.AdapterView; import android.widget.ArrayAdapter; import android.widget.Spinner; import android.widget.AdapterView.OnItemSelectedListener; public class MainActivity extends Activity { Spinner spin; String spin_val; String[] gender = { "Male", "Female" };//array of strings used to populate the spinner @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main);//setting layout spin = (Spinner) findViewById(R.id.spinner_id);//fetching view's id //Register a callback to be invoked when an item in this AdapterView has been selected spin.setOnItemSelectedListener(new OnItemSelectedListener() { @Override public void onItemSelected(AdapterView<?> arg0, View arg1, int position, long id) { // TODO Auto-generated method stub spin_val = gender[position];//saving the value selected } @Override public void onNothingSelected(AdapterView<?> arg0) { // TODO Auto-generated method stub } }); //setting array adaptors to spinners //ArrayAdapter is a BaseAdapter that is backed by an array of arbitrary objects ArrayAdapter<String> spin_adapter = new ArrayAdapter<String>(MainActivity.this, android.R.layout.simple_spinner_item, gender); // setting adapteers to spinners spin.setAdapter(spin_adapter); } } </code></pre> <p>To add a list of values to the spinner, you then need to specify a SpinnerAdapter in your Activity, which extends Adapter class.. A spinner adapter allows to define two different views: one that shows the data in the spinner itself and one that shows the data in the drop down list when the spinner is pressed.You can also download & refer to the complete <a href="http://blog.creatiosoft.com/?p=1194" rel="nofollow">spinner_demo</a> example project for better understanding.</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.
