I am trying to create a dyanmic tab application that has tabs on the left for each type of Food (e.g. Pasta, Dairy, etc. including those dynamically defined by user) and for each tab, have a listview connected to a SQLite database that updates. This is in the onCreate method:

setContentView(R.layout.foodCabinet_layout);
dbHelper = new FoodStorageDBHelper(this);
dbHelper.open();
Cursor foodTypes = dbHelper.getAllFoodTypes();
ArrayList<String> typeOfFood = new ArrayList<String>();
typeOfFoods.add(foodTypes.getString(1));
while(foodTypes.moveToNext()){
   typeOfFoods.add(foodTypes.getString(1));
}
final TabHost tbh = (TabHost)findViewById(R.id.food_tabhost_cabinet);
tbh.setup();
for(final String s : typeOfFood){
   TabSpec nts = tbh.newTabSpec(s);
   nts.setIndicator(s.replace('_', ' '));
   nts.setContent(new TabHost.TabContentFactory(){
       public View createTabContent(String tag)
       {
    ListView foodCabinetLV = new ListView(FoodCabinet.this);
   Cursor mCursor = dbHelper.getAllFoodsWithType(s);
    // Create an array to specify the fields we want to display in the list (only TITLE)
  String[] from = new String[]{FoodStorageDBHelper.KEY_NAME, FoodStorageDBHelper.KEY_YEAR,FoodStorageDBHelper.KEY_RANK};

  // and an array of the fields we want to bind those fields to (in this case just text1)
  int[] to = new int[]{R.id.childname,R.id.childyear,R.id.childrank};

  // Now create a simple cursor adapter and set it to display

  SimpleCursorAdapter notes = 
   new SimpleCursorAdapter(FoodCabinet.this, R.layout.food_row, mCursor, from, to);
  foodCabinetLV.setAdapter(notes);
  startManagingCursor(mCursor);
  foodCabinetLV.setOnItemClickListener(
    new AdapterView.OnItemClickListener() {
     public void onItemClick(AdapterView arg0, View arg1, int arg2,
       long arg3) {
      Intent i = new Intent();
      i.setClass(arg0.getContext(), EditFoodDialog.class);
      i.putExtra(FoodStorageDBHelper.KEY_ROWID, Long.toString(arg3));
      startActivityForResult(i, LoadFoodOrganizer.ACTIVITY_EDIT);
     }
    });
  return foodCabinetLV;
       }
   });
}

For some reason, it doesn't show anything... it's a blank screen. Any help would be very much appreciated.

Let me know!

Thanks! Jon
