问题 I have a ListView , which is in singleChoice mode . All I want is to display a RadioButton to the side, that when clicked highlights to say it is selected, and when a different one is clicked that one goes back to unselected and the new one becomes selected. Why is this so hard? This should not be this complicated. I've spent DAYS looking for an appropriate answer to this and I have found nothing, so I'm asking hopefully in a clear and concise manner. My layout for the listview (R.layout.view

问题 Im having a lot of trouble trying to create a customized item appearance for the TListView firemonkey control for Delphi XE7.

For example : I would like to have an item with a Title(on top) - A Description(Middle) - A Date (Bottom) - Button(Right). I could not find any good documentation about this but i got some samples of how to create an TListView with muti details, but the problem is : that sample is

问题 I have the MultiSelect property of the listView set to false and I'm trying to get a single listViewItem. But the available property is SelectedItems . I've been using the following code... foreach (ListViewItem item in listView1.SelectedItems) { //do something with item.text or whatever } Because I know there will only be one item selected. What is the correct way of doing this? 回答1: Usually SelectedItems returns either a collection, an array or an IQueryable . Either way you can access

问题 I have a list view which is populated via records from the database. Now i have to make some records visible but unavailable for selection, how can i achieve that? here's my code public class SomeClass extends ListActivity { private static List<String> products; private DataHelper dh; public void onCreate(Bundle savedInstanceState) { dh = new DataHelper(this); products = dh.GetMyProducts(); /* Returns a List<String>*/ super.onCreate(savedInstanceState); setListAdapter(new ArrayAdapter<String>

问题 I've got a ListView that works just great, except for this minor annoyance. I can use the trackball/dpad to move up and down my list, and the background changes according to which row has focus. But when I touch the row (click or long click), there's no background change letting me know what's been focused. I've tried setting 'focusable' and 'focusable in touch mode' to true on the rows, but it still doesn't work. Just in case it matters somehow: I am setting onClickListeners for each row.

问题 I have a listview which display the row through a datatemplate. When I select an item, I add the selected item to an observable collection and also set the value of "CarIsSelected" to true so I know which is selected. I'm having trouble on how I set the background color for the items I've selected that are added to the observablecollection? I hope this makes sense. Below is my code that I have so far. To give another example, if I select "item1", I add "item1" to the collection and highlight

问题 The ListViewItems I am displaying, categorized within ListView Groups in a ListView, are showing just their Text property, and truncated at that (even if they are the only item in a particular Group, and there are acres and hectares of screen real estate available). I would like them to indeed display their Text property, but in its entirety, not truncated. I am assigning the ListViewItem text property this way: public LegacyApplication(String AAppName, String ATitle, String ADesc, String
