getItemAtPosition() How to get readable data from the selected item in a ListView

由 回眸只為那壹抹淺笑 提交于 2019-12-04 12:18:13
问题 I have a listView of contacts that I got from the Android ContactManager sample. This list is showing up fine, but I can't figure out how to get info from the selected item, like "name" and "phone number". I can get the selected position, but the result of the mContactList.getItemAtPosition(position) is a ContentResolver$CursorWrapperInner and that doesn't really make any sense to me. I can't get heads or tails from that. Anyone know how I can get the name/id/phone number from the selected

Prevent WPF ListBox from selecting item under mouse when layout changes

由 浪尽此生 提交于 2019-12-04 11:14:43
If a WPF ListBox gets a MouseMove event while the mouse button is held down, it will change the listbox's selection. That is, if you click the mouse on item #1, and then drag over item #2, it will deselect item #1 and select item #2 instead. How can I prevent this? That's the short version. The slightly longer version is this: When the user double-clicks an item in my ListBox, I make other changes to my layout, which includes showing other controls above the ListBox. This moves the ListBox downwards, which means the mouse is now positioned over a different ListBoxItem than it was when the user

SelectedItem on ComboBox

问题 There is a ComboBox in the application which is bound to a collection of items. There are cases that user can select an item from the ComboBox but the selected item might not be ready yet so the ComboBox selected item must get back to the previous selected item (or some other item in the collection), but in the current application ComboBox always shows the selected item from the user instead of retrieving the valid item after setting it back and calling notify property change. The flowing is

Synchronizing a SelectedPath property with the SelectedItem in WPF's TreeView

由 倾然丶 夕夏残阳落幕 提交于 2019-12-04 04:10:45
问题 I am trying to create a SelectedPath property (e.g. in my view-model) that is synchronized with a WPF TreeView . The theory is as follows: Whenever the selected item in the tree view is changed ( SelectedItem property/ SelectedItemChanged event), update the SelectedPath property to store a string that represents the whole path to the selected tree node. Whenever the SelectedPath property is changed, find the tree node indicated by the path string, expand the whole path to that tree node, and
