I am trying to create custom background selector for my ExpandableListView. It works fine for all states other than focused. I am unable to identify which row is currently focused. Here is the code...

I have a LinearLayout layout with a ListView in it. I've made the android:background of the LinearLayout (I've also tried it on the ListView) be an image that I would like for my background.
This works fine enough. However, when I start scrolling through the ListView, the background often disappears and becomes black. If I move it around some more I may be able to get it to appear again. It would seem that Android is drawing over, or perhaps painting what's behind my background onto the items.
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:

And this is how I'm setting the selector:

I 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.

View 2 Replies View RelatedI have an activity with ListView and buttons below:
CODE:.................
ListView row contains delete button:
CODE:.................
In Adapter, Button onClickListener is set, also there are dummies to make list non-selectable:
CODE:..............
What I want is:
Always show buttons in the bottom of screen after list (no matter how long it is, there should be scroll if it's too long) ListView should not be selectable, I don't want row selection row delete button should be selectable (focusable) with touch and with trackball
And everything works except I can't focus row delete button with trackball (although it's working with touch).
A few days ago I was trying to fix this issue: I have a header (three ImageButton's) and a ListView. If I use the dpad, pressing DOWN to focus the ListView, the ListView shows as selected the seventh or eighth row, not the first one.
What I need to do is that the first element of the ListView get the focus (or selection) when I use the dpad, from another screen component, but instead, the seventh or eighth is selected.
I had minSdkVersion=3 in my manifest. When I changed it to minSdkVersion=4 it worked as expected (first row selected). Don't know why, but there is a difference between both.
l have a listview,the item in listview is tablelayout.when listitem can focus when i use the trackball,but when i touch the listitem,it lose focus,why? my adapter is extended ArrayAdapter like this

Say that the user has started my App and then switched off to use the Browser (so we have 2 sets of Tasks running). After a while, something happens to my app that requires the user's attention, so it posts a notification to notify the user. Is there a way to bring my App's task (and the Activity on top of the stack) out from the background when user clicks on my notification?
View 2 Replies View RelatedAny one knows why my ToggleButtons won't keep their states in a ListView?
Each list item includes a ToggleButton - when scrolled off from the screen their states are reset to unchecked...
I presume getView() is called once they're visible; however I'm not re instantiating them anyways.
I noticed that when item in in a list is clicked rapidly, there is chance that item in other row becomes dark. Especially when you click turn on/off bluetooth in system setting quickly. Has anyone noticed it and is there fix for this?
View 4 Replies View RelatedI'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. The row is comprised of LinearLayouts, TextViews, and a single ImageView. Focusable/clickable is 'true' for each row. Have not specified values for these on the ListView.
Trackable does act funny. I can only move between rows after touching inside the ListView. If I scroll trackball above the first item, it's impossible for me to scroll back into the list.
I've set the row (view) being used in a ListView as non-focusable along with non-clickable and have set the listview's focusable flag to false as well. However, I still get the yellow highlight when I use the scroll-ball on my device. How can I disable the yellow highlight and use my own special view/color instead upon focus?
View 6 Replies View RelatedI am facing a very mysterious Problem. I am using a ListView with CheckBoxes that can be clicked to select people. The row layout is the following:
<?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:orientation="horizontal" android:layout_width="fill_parent" android:layout_height="wrap_content"> <CheckBox android:focusable="false" android:onClick="onSelectPerson" android:layout_width="wrap_content" android:layout_height="wrap_content" android:gravity="center_vertical" android:layout_marginRight="5dip" android:layout_marginLeft="5dip"/> <TextView android:id="@+id/person_name" android:text="test" android:layout_width="wrap_content" android:layout_height="wrap_content" android:gravity="center_vertical" android:textSize="18dip" android:layout_marginLeft="5dip"/> </LinearLayout>
As long as the amount of rows doesen't exceed the screen size (-> no scrolling) everything works just fine. But as soon as I have more rows then the screen size (-> some rows are hidden and have to be scrolled to). I have a very mysterious phenomenon: If I check the top row and scroll down some of the previously hidden rows are randomly checked too. If I scroll up again, again some of the before hidden rows are randomly vhecked (the CheckBox I clicked in first place may or may not still be checked). Also the registered onSelectPerson callback is only called for the CheckBoxes I really click. The other CheckBoxes just change their state to "checked" without calling the callback method. I have the same phenomenom on the Archos IT 5 and the Nexus One. This must have something to do with the ListView implementation but I can't quite figure out what the problem is.
My ListActivity is bound to an ArrayAdapter where I have overriden the getView() method. If I change the visibility of a widget in that method or modify the view's background color, those changes somehow get lost once that modified list item returns after being scrolled off the screen. In fact, some other view in the list is picking up the changes. How do I get the modified view to look the same when it's redisplayed after scrolling?

View 1 Replies View RelatedI have some EditViews in the rows of a ListView.This works just fine except when the soft keyboard raises and lowers.When I touch the EditView within the ListView with the soft keyboard down, focus jumps to the EditView, then the keyboard comes up, removes focus from the EditView and sets focus to the ListView, resulting in an odd user experience with the focus no-where visible.Touching the EditViews with the keyboard already showing works as you would expect.The problem seems to be with the soft keyboard lowering and raising and the ListView getting confused about where focus should be placed.

Is there a way to show that a WebView item contained as a item in a ListView is selected? Right now the WebView does not seem to display its contents transparently like every other control so it takes up the entire view and does not show its state as selected.
Also, when the content of the WebView is selected, scrolling down with the track back does not seem to cause the WebView to loose focus. If I continue to scroll down with the track ball, all of a sudden an item in the middle of the ListView gets selected.
I'm facing problem in scrolling. I've 20-25 items in my List, if i checked first check box, scroll down, then come up, my checked status lost (becomes unchecked), in cursor adaptor. If i use base adaptor problem is resolved but major issue with base adaptor is performance, if my list goes beyond the 100 items.
