I 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.

I have created a ListView and applied a selector to it as follows
CODE:..............
When focussed or pressed, the background of the ListView item comes as specified in the selector. But the default background is never applied, can you tell me what is wrong?
By the way, this is the customised row xml I've used:
CODE:...................
I 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...
I'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.
I 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.
Trying 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?
I 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.
Is 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:
CODE:.........................
Look for examples where ListViews can show multiple view types.

View 1 Replies View RelatedI 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.

Is it possible to add a view dynamically that overlaps other views in the layout. I have Linear Layout defined for the activity. As part of the Layout I have a custom View. The content changes dynamically and sizes appropriately based on the content size, with fill_parent for width and wrap_content for height. But what I want is, dynamically take over the full screen and then based on a click go back to the normal mode. Is there a mode to display a view where - in it can overlap all other views in the layout?

using voice input is easy:
1. i press the GV icon
2. i talk
3. text coming out, there will be miss typed/heard sentences
4. you know, if the system doubt your speech and want to correct it, you just tap the word with grey underline,it indicating that it have multiple option
5. then you choose the correct sentences
My step number 4 is a problem, because the correction that pop up to correcting/delete sentences is being blocked by keyboard, that is why i say it also a keyboard problem. so i cannot choose anything from it. and i have this problem since 4.2.2, the first day i upgraded it to 4.3 is okay, but suddenly it happen again. i don't think i will resetting or formatting because i have a lot of app and chat history that i cannot delete.

View 1 Replies View Relatedwhat I would find really usefull is a voicemail greeting selector that would allow you to record different greetings for different situations, personal, business etc. Record and then title the message which then becomes selectable from a menu. Ideally linked to a button or shortcut of some kind.
For example if I am out of the office I redirect all calls to my mobile, if I am unavailable my personal greeting is used via my network provider. Not very professional and to change this every time would be impracticle.
