Android :: ListView Item Selector To Use State_checked?
Sep 18, 2010Trying to get an Android ListView to do what I want.
I want to have a ListView in single choice mode with a custom row layout that has a different background color for selected, pressed and checked (i.e. the choice is shown by a color rather than a check mark - this is what I would normally call the "selection" but selection in android seems line I'm about to choose before I press it)
I thought of trying a background selector with the three states in it. It works fine for state_selected and state_pressed, but not state_checked. So I created a CheckableRelativeLayout that extends RelativeLayout and implements Checkable and used for the view of each row.
A simplified version is shown here:
CODE:.....
bkg_selector looks like
CODE:..............
The colors are defined elsewhere.
This still didn't work. So in the custom ListAdapter I tracked the "checked" row and tried (in getView) if( position == checkedPosition ) ret.getBackground().setState(CHECKED_STATE_SET);
And it STILL doesn't work. How can I get it to do what I want?
Android :: ListView Item Background Via Custom Selector
Apr 1, 2010Is it possible to apply a custom background to each Listview item via the list selector?
The default selector specifies @android:color/transparent for the state_focused="false" case, but changing this to some custom drawable doesn't affect items that aren't selected. Romain Guy seems to suggest in this answer that this is possible.
I'm currently achieving the same affect by using a custom background on each view and hiding it when the item is selected/focused/whatever so the selector is shown, but it'd be more elegant to have this all defined in one place.
For reference, this is the selector I'm using to try and get this working:
CODE:...............
And this is how I'm setting the selector:

Android :: ListView Selector Color ?
Jan 10, 2010I have 2 questions regarding a ListView in Android:
How can I get the color of the listview's focused row ? I tried to use the ListView.getSelector() method, which according to its documentation should give me what I'm looking for, but it's giving me a Drawable object which I don't know how to retrieve the color from (if possible...).
How can I set the color of the listview's focused row ? Here I tried to use the setSelector() method on the listview, passing it a ColorDrawable object, but the result of doing it is that the whole background of the list view is painted in that color... and this is not what I wanted of course...
Android : Add 'permanent' Selector In ListView?
Aug 30, 2010I'm looking for suggestions on how to go about adding a ListView selector that is 'permanent'. By this, I mean a single row in the ListView is always highlighted; it should move up or down in reponse to any D-pad presses (i.e. like the default selector) but also remain set/highlighted if the user were to scroll the ListView in either direction (i.e. it's still highlighted even when it's off-screen).
I've looked at using the standard selector mechanism, but am unable to get the selector to remain in place if the ListView is touched (and thus scrolled), so it makes me think that this isn't the best option? Perhaps there's a <selector> "state_*" that I've ignored?
The other option would be to use the onItemSelected() callback, but at first look this appears more convoluted?
Any suggestions/recommendations/experiences gratefully received.
Android :: Selector - Listview With A Custom Item_row.xml
Mar 5, 2010I have a listview with a custom item_row.xml. I've defined a selector in this way:
CODE:................
And then put into item_row.xml in this way:
CODE:...................
I want 2 things:
When i move with arrow keys, the item selected changed its background. It's works fine with the actual implementation of selector.
When i press a item, the item changed its background too, but it doesn't work with the actual selector.
I try to set also into the ListView android:listSelector="@drawable/list_selector" but it doesn't work neither.
Android :: Overlap Problem With ListView Selector
Apr 28, 2010I am trying to style my ListView with two 9-patch background images (16px * 9px), one dark image for default state and another green image for selected and pressed state.
It works except for just one problem that when I select or press one list item, it seems that the selected item overlap the next one a little bit as I can see some pixels of the green background image is on the top of next item.
Android :: ListView Selector - Selection Does Not Get Removed
Sep 27, 2010I have a ListView. When I click on a ListItem, I set the background of the ListItem (it's view) to another color:
CODE:........
Here is my adapter:
CODE:......
The problem is, if I select multiple rows, then multiple rows have a colored background. I only want the clicked item to have a colored background. So if I click on row 2, I want it to turn red, then if I click row 1, I want row 2 to go back to normal, and row 1 to turn red.

View 1 Replies View RelatedAndroid :: ListView - ExpandableListView As Well - Selector Highlight Problems With Custom Background
Jul 13, 2009I have an expandable list with a custom adapter. Everything works great but there are two problems.
First whenever a group or child has a custom background color set the orange selector does not show up. If I dont setup a color the selector draws nicely and also the fade away for context menus works.
Second, some of my text inside a list item is linkified. Whenever a link is present the selector does not draw again. It seems that the click event is handled by the internal link view instead of propagating to the list view.
