Question

I’ve been playing with a sample application I found online. Just changing things to see how it works. Yesterday this was not an issue. Today is a different story. I seem to write the correct info to the db. I’ve checked through log outputs. When I return the information through a cursor I get “null”. So, say I enter “Eggs”,”Bread”, and “Candy”. I get back “null”,”null”, and “null”.

It all starts with the listener for the add grocery button. Adds to the db and writes the list to an label.

Any help?

  private void addEvent(String title) {
    SQLiteDatabase db = eventsData.getWritableDatabase();
    ContentValues values = new ContentValues();
    Log.v(TAG, "Adding " + title);
    values.put(EventsDataSQLHelper.TITLE, title);
            db.insert(EventsDataSQLHelper.TABLE, null, values);

  }

  private Cursor getEvents() {
    SQLiteDatabase db = eventsData.getReadableDatabase();
    Cursor cursor = db.query(EventsDataSQLHelper.TABLE, null, null, null, null,
        null, EventsDataSQLHelper.TITLE);    
    startManagingCursor(cursor);
    return cursor;
  }

  private void showEvents(Cursor cursor) {
    StringBuilder ret = new StringBuilder();
    while (cursor.moveToNext()) {            
      String title = cursor.getString(1);
      ret.append(title + "\n");
      Log.v(TAG, "SHOWING RET VARIABLE" + ret);
    }
    t.setText(ret);   

  }
  View.OnClickListener myhandler = new View.OnClickListener()
  {
      @Override
      public void onClick(View GLview) 
        {
            EditText eT = (EditText)findViewById(R.id.itemName1);
            editTextStr = eT.getText().toString();
            Log.v(TAG, editTextStr);
            if(editTextStr != null)
            {
                addEvent(editTextStr.toString());
                Cursor cursor = getEvents();
                showEvents(cursor);             
                eT.setText(null);
            }
        }
  };

Make sure cursor points to the first element of the result cursor.moveToFirst();
Then call cursor.moveToNext()
