Hi everybody!
I am pretty new to Android programming, but I do know Java (and a bit
of XML)... still I can't understand where's the problem in this case.
What I want is a Tab Layout that contains, for each tab, a different
view.
public class MyApp extends TabActivity {
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; // Resusable TabSpec for each tab
Intent intent; // Reusable Intent for each tab
// Create an Intent to launch an Activity for the tab (to be
reused)
intent = new Intent().setClass(this, DatiAttrib.class);
// Initialize a TabSpec for each tab and add it to the TabHost
spec = tabHost.newTabSpec("artists").setIndicator("First
Tab").setContent(intent);
tabHost.addTab(spec);
// Do the same for the other tabs
intent = new Intent().setClass(this, AbilArc.class);
spec = tabHost.newTabSpec("albums").setIndicator("Second
Tab").setContent(intent);
tabHost.addTab(spec);
intent = new Intent().setClass(this, DifesePregi.class);
spec = tabHost.newTabSpec("songs").setIndicator("Third
Tab").setContent(intent);
tabHost.addTab(spec);
tabHost.setCurrentTab(0);
}
}
...just like the Tab Layout tutorial.
Then I coded every different view in a XML file, each referred by
a .java file (a Class that extends Activity) pretty much like this:
public class DatiAttrib extends Activity {
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.datiattrib);
}
}
Where datiattrib.xml is the layout file.
When it comes to testing,though, the program shows an error and forces
to exit.
Is there anything wrong with this approach?
Thanks!
