If Tabs and Activities don't go together..Is there a way to cheat?

Question

I am having a real hard time on putting my activities in tabs. I have an activity that parses an XML file and puts them on a list, and it works perfectly on its own. When I call it on a tab however it does not work (i get the dreaded "Sorry! blah blah.. has stopped unexpectedly" prompt... BTW yes I did the manifest).

I have migrated the activities to work as one activity, voila! it worked!!! However this is not the way we wanted to go with this project - WE REALLY NEED to have separate activities.

So as many people had found out that tabs and activities doesn't work well together is there a way to work around it? Some sort of emulsifier maybe?

Here is the code:

import android.app.Activity; import android.content.Intent; import android.os.Bundle; import android.widget.TabHost; import android.widget.Toast;

public class TabDemo extends Activity{

/** data members go here*/

public void onCreate(Bundle icicle) {
    super.onCreate(icicle);
    setContentView(R.layout.main);

    try {
        TabHost tabs= (TabHost)findViewById(R.id.tabhost);

        tabs.setup();
        Intent callResultHits = new Intent(this, my.tabebd.layout.ResultHits.class);

        TabHost.TabSpec spec = tabs.newTabSpec("tag1");
        spec.setContent(callResultHits);
        spec.setIndicator("Result",   getResources().getDrawable(R.drawable.ic_tab_search_result) );
        tabs.addTab(spec);

        spec = tabs.newTabSpec("tag2");
        spec.setContent(R.id.tab2);
        spec.setIndicator("Details",getResources().
                             getDrawable(R.drawable.ic_tab_details));
        tabs.addTab(spec);

        tabs.setCurrentTabByTag("tag1");
    } catch (Throwable t) {
        // TODO Auto-generated catch block
        Toast.makeText(this, "Exception: " + t.toString(), 50000).show();
    }
}

here is one of the activities...

public class ResultHits extends Activity implements OnItemClickListener {
ListView listView_titles;
ArrayList<String> items = new ArrayList<String>();
String [] test = {"1", "2","3"};

    @Override
    public void onCreate(Bundle savedInstanceState) {
       super.onCreate(savedInstanceState);



    listView_titles = (ListView)findViewById(R.id.list);

    listView_titles.setAdapter(new ArrayAdapter<String>
    (this,R.layout.row, R.id.row_text,test));


}

}

I omitted the xml parsing part... if this basic list can be shown inside the tab then it will be perfect. TY in advance

BTW setcurrenttabByTag was previously setCurrenttab(2)..actualy i did these values 0,1, 2, 3 just in case ;)

Post your code I think you will not have problems putting activities into every tab, This is a basic Example of how put activities in tabs,

    static  TabHost 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, MainActivity.class);
           // Initialize a TabSpec for each tab and add it to the TabHost
           spec = tabHost.newTabSpec("MainActivity")     
             .setIndicator(null, null)
               .setContent(intent);
           tabHost.addTab(spec);

           // Do the same for the other tabs
           intent = new Intent().setClass(this, SecondActivity.class);
           spec = tabHost.newTabSpec("SecondActivity")         
           .setIndicator(null, null)               
           tabHost.addTab(spec);

           intent = new Intent().setClass(this, ThirdActivity.class);
           spec = tabHost.newTabSpec("ThirdActivity")
               .setIndicator(null, null)
               .setContent(intent);
           tabHost.addTab(spec);

           intent = new Intent().setClass(this, FourthActivity.class);
           spec = tabHost.newTabSpec("FourthActivity")
               .setIndicator(null, null)
               .setContent(intent);
           tabHost.addTab(spec);
