    <p>Currently my code loads a <code>TabWidget</code> with 4 tabs. The first tab points to a disclaimer page which also takes in a username from a edittext box and stores it internally on the phone. I would like to have an if condition which checks to see if the username is stored on the phone and if it is then show the user a different "thank-you" page than the original disclaimer page. I believe my code isn't working because it's under the onCreate function and isn't refreshing... </p> <pre><code> public class TabWidgetActivity extends TabActivity { /** Called when the activity is first created. */ @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); Resources res = getResources(); // Resource object to get Drawables TabHost tabHost = getTabHost(); // The activity TabHost TabHost.TabSpec spec; // Reusable TabSpec for each tab Intent intent; // Reusable Intent for each tab // Create an Intent to launch an Activity for the tab (to be reused) String username = null; String pulledUsername = getPreferences(MODE_PRIVATE).getString("username",username); // ******* MAIN PART I'M HAVING TROUBLE WITH ******************************** if (pulledUsername != null){ intent = new Intent().setClass(this, HomeActivity.class); } else { intent = new Intent().setClass(this, DisclaimerActivity.class); } // ^^^^^^^^^^^^^^^ MAIN PART I'M HAVING TROUBLE WITH ^^^^^^^^^^^^^^^^^^^^^^ // Initialize a TabSpec for each tab and add it to the TabHost spec = tabHost.newTabSpec("home").setIndicator("Home", res.getDrawable(R.drawable.ic_tab_home)) .setContent(intent); tabHost.addTab(spec); // Do the same for the other tabs intent = new Intent().setClass(this, ShowMapActivity.class); spec = tabHost.newTabSpec("map").setIndicator("Map", res.getDrawable(R.drawable.ic_tab_map)) .setContent(intent); tabHost.addTab(spec); intent = new Intent().setClass(this, SurveyActivity.class); spec = tabHost.newTabSpec("survey").setIndicator("Survey", res.getDrawable(R.drawable.ic_tab_web)) .setContent(intent); tabHost.addTab(spec); intent = new Intent().setClass(this, AnalysisActivity.class); spec = tabHost.newTabSpec("analysis").setIndicator("Analysis", res.getDrawable(R.drawable.ic_tab_analysis)) .setContent(intent); tabHost.addTab(spec); tabHost.setCurrentTab(2); } } </code></pre>

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.
