Launch Time Zone list in Android for pick/result

Question

I see that it's possible to launch the date & time settings via an intent in Android, but what I'd like to do is launch just the list that shows the time zones (clicking "Select time zone") and get back the selected value without having the selection modify the user's date & time settings. Any idea how to do this?

If you are talking about a spinner you could do something like this:

ArrayAdapter <CharSequence> adapter =
          new ArrayAdapter <CharSequence> (this, android.R.layout.simple_spinner_item );
    adapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
    String[]TZ = TimeZone.getAvailableIDs();
    ArrayList<String> TZ1 = new ArrayList<String>();
    for(int i = 0; i < TZ.length; i++) {
        if(!(TZ1.contains(TimeZone.getTimeZone(TZ[i]).getDisplayName()))) {
            TZ1.add(TimeZone.getTimeZone(TZ[i]).getDisplayName());
        }
    }
    for(int i = 0; i < TZ1.size(); i++) {
        adapter.add(TZ1.get(i));
    }
    final Spinner TZone = (Spinner)findViewById(R.id.TimeZoneEntry);
    TZone.setAdapter(adapter);
    for(int i = 0; i < TZ1.size(); i++) {
        if(TZ1.get(i).equals(TimeZone.getDefault().getDisplayName())) {
            TZone.setSelection(i);
        }
    }
