Solving this issue took me several days of investigation and research.
The structure of my app is the following:
Three tabs are set for this TabHost.
Each tab click opens proper ListView page.
OnClick action for ListView item opens proper Activity, which was done, by the following code:
Intent intent = new Intent(this, newActivity.class); this.startActivity(intent);
The problem was, that newActivity was opened in new Window, but I wanted to open it in the same window.
Asking for help on stackoverflow.com didn’t help.
And then suddenly I found the following solution Experience – Multiple Android Activities in a TabActivity
Now my code to run newActivity look as following:
TabGroupActivity parentActivity = (TabGroupActivity)getParent();
parentActivity.onBackPressed();
Intent newIntent = new Intent(getParent(), newActivity.class);
parentActivity.startChildActivity("newActivity", newIntent);
Note: if you have any kind of Widget functionality, which pop-ups in your View, then make sure, that getParent() is used for Context.

Hi,
take a look on my code for SimpleList implementation.
public class App extends ListActivity { static final ArrayList> list =
new ArrayList>();
public Dialog dialog;
public String about_text;
public TextView text;
private void populateList() {
list.clear();
HashMap temp = new HashMap();
temp.put("name","First line");
list.add(temp);
HashMap temp1 = new HashMap();
temp1.put("name","Second line");
list.add(temp1);
HashMap temp2 = new HashMap();
temp2.put("name","Third line");
list.add(temp2);
HashMap temp3 = new HashMap();
temp3.put("name","Forth line");
list.add(temp3);
}
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
SimpleAdapter adapter = new SimpleAdapter(
this,
list,
R.layout.about_list,
new String[] {"name"},
new int[] {R.id.option_name}
);
populateList();
getListView().setBackgroundColor(Color.parseColor("#FFFFFF"));
getListView().setCacheColorHint(Color.parseColor("#FFFFFF"));
setListAdapter(adapter);
dialog = new Dialog(AboutApp.this);
dialog.setContentView(R.layout.about);
}
@Override
protected void onListItemClick(ListView l, final View v, int position, long id) {
super.onListItemClick(l, v, position, id);
Intent newIntent = new Intent(getParent(), newActivity.class);
switch ((int)l.getItemIdAtPosition(position)) {
case 0:
// here is the code for first line
startActivity(newIntent);
break;
case 1:
// here is the code for second line
break;
case 2:
// here is the code for third line
break;
case 3:
// here is the code for forth line
break;
// default:
// return super.onOptionsItemSelected(item);
}
}
}
