Java code

public class MainActivity extends ListActivity  {
    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        Cursor cr=getContentResolver().query(People.CONTENT_URI, null, null, null, null);
        startManagingCursor(cr);
        
        ListAdapter adapter = new SimpleCursorAdapter(this, 
                // Use a template that displays a text view
                android.R.layout.simple_list_item_1, 
                // Give the cursor to the list adatper
                cr, 
                // Map the NAME column in the people database to...
                new String[] {People.NAME} ,
                // The "text1" view defined in the XML template
                new int[] {android.R.id.text1}); 
        setListAdapter(adapter);

    }
}

XML code

<manifest xmlns:android="http://schemas.android.com/apk/res/android"
      package="com.amker.getContact"
      android:versionCode="1"

                  android:label="@string/app_name">

                <action android:name="android.intent.action.MAIN" />
                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
