    <p>I have a problem with my Code:</p> <p>I want to make a Highscore list with Google AppEngine and it works. Google AppEngine returns a String which is parsed and filled in a Layout. The activity HighscoreListe connects to AppEngine and will get this string.</p> <p>The problem with my Highscore layout in the way I wrote below is that this activity (HighscoreListe) starts multiple times when I start the TabLayout. So I get a StringIndexOutOfBoundsException.</p> <p>I want to start intent2 when I change to Tab 2 and intent3 when I change to Tab3. So that the highscores will only be loaded in the 2nd or 3rd difficulty when I click on this difficulty.</p> <pre><code>public class HighscoreTabLayout extends TabActivity{ @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); TabHost tabHost = getTabHost(); System.out.println(MenuMainActivity.getDifficulties()); int diffCount = -1; System.out.println(diffCount); TabSpec tabSpec1 = tabHost.newTabSpec(MenuMainActivity.getDifficulties()[++diffCount].getName()); // setting Title and Icon for the Tab tabSpec1.setIndicator(MenuMainActivity.getDifficulties()[diffCount].getName());//, getResources().getDrawable(R.drawable.icon_photos_tab)); Intent intent1 = new Intent(this, HighscoreListe.class); intent1.putExtra("name", MenuMainActivity.getDifficulties()[diffCount].getName()); tabSpec1.setContent(intent1); System.out.println(diffCount); TabSpec tabSpec2 = tabHost.newTabSpec(MenuMainActivity.getDifficulties()[++diffCount].getName()); tabSpec2.setIndicator(MenuMainActivity.getDifficulties()[diffCount].getName());//, getResources().getDrawable(R.drawable.icon_songs_tab)); Intent intent2 = new Intent(this, HighscoreListe.class); intent2.putExtra("name", MenuMainActivity.getDifficulties()[diffCount].getName()); tabSpec2.setContent(intent2); System.out.println(diffCount); TabSpec tabSpec3 = tabHost.newTabSpec(MenuMainActivity.getDifficulties()[++diffCount].getName()); tabSpec3.setIndicator(MenuMainActivity.getDifficulties()[diffCount].getName());//, getResources().getDrawable(R.drawable.icon_videos_tab)); Intent intent3 = new Intent(this, HighscoreListe.class); intent3.putExtra("name", MenuMainActivity.getDifficulties()[diffCount].getName()); tabSpec3.setContent(intent3); System.out.println(diffCount); TabSpec tabSpec4 = tabHost.newTabSpec(MenuMainActivity.getDifficulties()[++diffCount].getName()); tabSpec4.setIndicator(MenuMainActivity.getDifficulties()[diffCount].getName());//, getResources().getDrawable(R.drawable.icon_videos_tab)); Intent intent4 = new Intent(this, HighscoreListe.class); intent4.putExtra("name", MenuMainActivity.getDifficulties()[diffCount].getName()); tabSpec4.setContent(intent4); System.out.println(diffCount); // Adding all TabSpec to TabHost tabHost.addTab(tabSpec1); tabHost.addTab(tabSpec2); tabHost.addTab(tabSpec3); tabHost.addTab(tabSpec4); tabHost.setCurrentTab(1); } </code></pre> <p>}</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.
