populating a list view with sql database items

由 荒凉一梦 提交于 2019-12-06 09:39:02
问题 My application is based on displaying a dialog box when the user enters the "add category" button.

由 谁说我不能喝 提交于 2019-12-06 08:53:20
问题 I have a lisview that I want to add images to. The examples that I found early on showed using simple_list_item_1, but it doesn't seem to allow what I want.
