I am currently trying to customize ImageButton to show different draweables as background of the Button while keeping the image set via the src attribute.
That's my custom_button.xml:

I'm attempting to change the background color of an Android TextView widget when the user touches it. I've created a selector for that purpose, which is stored in res/color/selector.xml and roughly looks like that:
CODE:................
The clickable attribute of the TextView is "true", in case that's of interest.
When I assign this selector to a TextView as android:background="@color/selector",
I'm getting the following exception at runtime: ERROR/AndroidRuntime(13130): Caused by: org.xmlpull.v1.XmlPullParserException: Binary XML file line #6: <item> tag requires a 'drawable' attribute or child tag defining a drawable
When I change the attribute to drawable, it works, but the result is looking completely wrong because the IDs appear to be interpreted as image references instead of color references (as the "drawable" suggests).
What confuses me is that I can set a color reference, e.g. "@color/black", as the background attribute directly. This is working as expected. Using selectors doesn't work.
I can also use the selector as the textColor without problems.
What's the correct way to apply a background-color-selector to a TextView in Android?
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:.........................
How to do a listview which looks like this? I'm interesting in the style of rows with an own background and the selector working fine.
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.

I have the following linear layout. What I don't understand is if I set the background to another image, the padding information are reset. Is there a way to prevent this?
<LinearLayout android:id="@+id/aPanel"
android:orientation="horizontal" android:layout_width="fill_parent"
android:layout_height="wrap_content" android:background="@drawable/bkground"
android:paddingLeft="15dp" android:paddingRight="15dp">
<!-- some children here -->
</LinearLayout>
I see the position of the children get shifted when I change the backround drawable of the linearlayout 'aPanel'.

View 3 Replies View RelatedMy app was built on the Android 1.5 platform. I'm in the process of bumping the APIs used to 2.1 . I am still leaving minSdkVersion=3 / targetSdkVersion = 7 in order to support older platforms.
I've made the required drawbles-hdpi / -mdpi - ldpi-v4 folders. Everything is looking great across various AVDs of HVGA/WVGA shapes and sizes.
Everything, except my tabs.
In AVDs running Android 1.5 and 1.6, my tab background colors are appropriate: http://www.shelvesforandroid.com/1p6below.png
However, for platforms running 2.1 and above, something seems to have gone awry:

Notice that the unselected tab color is correct, but the selected tab looks like it's just bleeding the same color as my images.
What can I do to fix this? Enforce the background color to be the same as 1.6-era ?
What is causing this tab color change?
Code...
Can anybody guide me how do I change the background image or color of selected tab?

View 2 Replies View RelatedI use the AlertDialog class in my application. By default, these alert dialogs have a transparent background. I'm trying to use an opaque background instead, very unsuccessfully.
These are my styles:
CODE:....................
I applied the "MyOpaqueActivity" style successfully for whole activities (the window background is changed to "my_background"), but it doesn't work for alert dialogs within those activities. The "alertDialogStyle" attribute and my "MyOpaqueAlertDialog" style don't seem to have any effect.
So how can I change the background of these alert dialogs?
