                    R.layout.group_row, // Layout for the first-level entries
                    new String[] { "BetGroup" },    // Key in the groupData maps to display
                    new int[] { R.id.childname },       // Data under "colorName" key goes into this TextView
                    createBetChildList("next") ,    // childData describes second-level entries
                    R.layout.child_row, // Layout for second-level entries
                    new String[] { "betText","betRate","betID" },   // Keys in childData maps to display …
