猕猴桃多色ListView
我想为列表视图中的所有元素定义唯一的颜色
实际上我是这样创建列表视图的：
from kivy.adapters.listadapter import ListAdapter
from kivy.uix.listview import ListItemButton, ListView
data = ["blue","green","yellow","black","white"]
list_adapter = ListAdapter(data=data,
args_converter=args_converter,
cls=ListItemButton,
selection_mode='single',
allow_empty_selection=False)
list_view = ListView(adapter=list_adapter)
所有元素都具有绿色背景，我想要多色listview，我希望蓝色项目具有蓝色背景，黑色项目具有黑色背景...等。
有可能吗？ 感谢您的帮助

您必须使用$lead_tags_list = array();
$tags_source = $this->get_tags_by_name('Lead Source');
$tags_status = $this->get_tags_by_name('Lead Status');

$tags_lead_priority = $this->get_tags_by_name('Lead Priority');
$this->contact_data_set = 0;

->select('a.*')
->selectRaw('(SELECT GROUP_CONCAT(tag_id) FROM bas_lead_to_tag WHERE lead_id = a.lead_id) as tag_list')
