嗨，我必须在我的可扩展 listview android 应用程序中创建 2 个组。但我无法开发这个。请帮助我。这是我的代码：
SimpleExpandableListAdapter expListAdapter =
new SimpleExpandableListAdapter(
this,
createGroupList(), // Creating group List.
R.layout.group_row, // Group item layout XML.
new String[] { "OrderInfo","CustomerInfo"}, // the key of group item.
new int[] { R.id.order,R.id.customer},
// ID of each group item.-Data under the key goes into this TextView.
createChildList(), // childData describes second-level entries.
R.layout.single_list_item,
// new String[] {"KEY_ARTIST"},
// new int[] { R.id.payment_label} // Keys in childData maps to display.
// Layout for sub-level entries(second level).
new String[] {"KEY_ARTIST","KEY_DURATION","KEY_SUBTOTAL","KEY_DISCOUNT","KEY_COUPON","KEY_COST"},
new int[] { R.id.payment_label,R.id.total_label,R.id.discount_label,R.id.discount_label,R.id.coupon_label,R.id.cost_label}// Keys in childData maps to display.
// new int[] { R.id.payment_label,R.id.total_label} // Data under the keys above go into these TextViews.
);
setListAdapter( expListAdapter ); // setting the adapter in the list.
}catch(Exception e){
System.out.println("Errrr +++ " + e.getMessage());
}
}
/* Creating the Hashmap for the row */
@SuppressWarnings("unchecked")
private List createGroupList() {
ArrayList result = new ArrayList();
for( int i = 0 ; i < 2 ; ++i ) { // 15 groups........
HashMap m = new HashMap();
m.put( "OrderInfo","CustomerInfo " + i ); // the key and it's value.
result.add( m );
}
return (List)result;
}
在这里我必须创建 2 组 orderinfo 和 customerinfo..如何创建上面的代码..请帮助我。
