I have a drawable selector as a background for each item in a ListView
to highlight the selected row. Eveything works fine in Ice Cream Sandwich, but doesn't seem to work in Jelly Bean. Can't find any documentation saying what changes could have caused it to stop working and what I need to do to fix it.
By not working, I mean when I click on a row in the ListView
the item's background color isn't turning the @color/blue
color, but it does in ICS.
This is the selector code I'm using (listing_selector.xml):
<selector xmlns:android="http://schemas.android.com/apk/res/android" >
<item android:state_focused="true" android:drawable="@color/blue" />
<item android:state_pressed="true" android:drawable="@color/blue" />
<item android:state_activated="true" android:drawable="@color/blue_selected" />
<item android:state_selected="true" android:drawable="@color/blue_selected" />
<item android:drawable="@android:color/transparent" />
</selector>
This is the layout of the ListView
item:
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="wrap_content"
android:layout_height="fill_parent"
android:orientation="horizontal"
android:background="@color/listing_selector"
>
<TextView
android:id="@+id/text"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentLeft="true"
/>
</RelativeLayout>
This the blue color resource:
<resources>
<color name="blue">#ff33b5e5</color>
</resources>
UPDATE 1:
Tried moving the selector from the color
folder to the drawable
folder and updating the code to this:
android:background="@drawable/listing_selector"
UPDATE 2:
Also, on the ListView
, tried adding this:
<ListView android:id="@android:id/list"
android:layout_width="wrap_content"
android:layout_height="fill_parent"
android:listSelector="@drawable/listing_selector"
/>
UPDATE 3:
I thought it might be something in my code, but I removed all the code from onListItemClick
of the ListView
and still the selector
isn't working.
UPDATE 4:
I've narrowed it down to state_selected
or state_activated
not working as, state_pressed
seems to be working
UPDATE 5:
I think I was mistaken. I don't think the selector is being recognized, at all. I was confusing the built-in ListView
highlighting as my selector. I'm now wondering if it has something to do with the way my project is setup. I have the selector in a Library Class. Maybe something changed with that from ICS to JB, however moving the selector to my app's project didn't seem to fix it.
UPDATE 6:
Ok, after some more hair pulling, I've narrowed it down, again, to either state_selected
or state_activated
not being recognized, as changing the color for state_pressed
does work, which means my selector is being recognized. From the comments in seems to be something with my app specifically as others have been able to get selectors working with Jelly Bean.
Though something else that is interesting is that changing the drawable
value for the default state is not recognized. Where I have color/transparent
, I would think changing that to a color would cause the listing to change to that color, but it doesn't.
Also, this isn't working in ICS either.
UPDATE 7:
After even more hair pulling, I've discovered that long-pressing on a menu item results in that item's color being changed. Just clicking on an item still does not work. Not even sure what the means.
** Final Update:**
I give up, I removed the selector and am just refreshing the ListView
on click and remembering the position clicked and highlighting it from code. Not ideal, but not worth the effort to try to fix.
Okay, i think its an issue with your selector. Try removing the state_focused and the state_activated. You could try this for your selector:
<!-- Disabled State -->
<item
android:state_enabled = "false"
android:state_focused = "true"
android:state_pressed = "true"
android:drawable="@android:color/transparent">
</item>
<item
android:state_enabled = "false"
android:state_focused = "true"
android:drawable="@android:color/transparent">
</item>
<!-- Pressed State -->
<item
android:state_pressed = "true"
android:state_focused = "true">
<shape>
<solid android:color="@color/blue"/>
</shape>
</item>
<item
android:state_pressed = "true"
android:state_focused = "false">
<shape>
<solid android:color="@color/blue"/>
</shape>
</item>
<!-- Normal State -->
<item
android:drawable="@android:color/transparent">
</item>
I found that I needed to use a shape object too instead of android:drawable
, because on pre-ICS phones, the whole list will be highlighted that color instead of the pressed list item.
You can add in your state_selected
code too, but I'm not sure how it will be used. Check out the default selector code for jelly bean for the states they use: list_selector_background.xml.
