I'm having a hard time understanding how I can create my own Gallery item. Specifically, I want to alter the appearance of the rectangle that surrounds whatever is the currently selected item (and remove altogether the rectangle that surrounds the non selected items).
Is there a good tutorial on how to create my own styles and pass them into my Widgets?
[Edit]
When initializing my gallery I hand it this
R.styleable.GalleryTheme_android_galleryItemBackground
and
R.styleable.GalleryTheme
I'm sure if I could crack those open, I could then copy and alter into what I want.... but where does Android store these?
[/edit]
The contents of those themes can most likely be found some where in the source code of the Android Open Source Project. It'l probably be somewhere here in the resources folder
Ok... this thread answers the actual question:
Android Hello, Gallery tutorial -- "R.styleable cannot be resolved"
Hope it helps someone.

I am trying to do a drawer activity with Android Studio and I'm wanting to personalize the icons used. I've downloaded the icons I want to use and for the most part, it's okay.
In fact, I can modify all the android:icon icons but I have no idea how to modify the app:srcCompat icons. I don't know how to detect the image I want to use in this case...
Do you know how I can do it? Could you explain this to me?
Thanks a lot!
Edit: The file I'm working on as a base is the generated project with Drawer activity as the main activity. For example, if I wanted to modify the icon in the nav_header_main.xml file, how could I do to have my image (.png) transformed in a way detected by Android Studio as compatible with srcCompat
Ensure your image file is in res/drawable folder(or drawable-xhdpi/xxhdpi, determined by your design)
Refer it by app:srcCompact="#drawable/$IMAGE_FILE_NAME" in your xml.
Then you should see what you want.
Please check the doc to further understand the official usage.
Well... I was blind! I was wondering how I could add my icons but they were, I was just mistaking on the address... #android:drawable/... is obviously not #drawable/... but I didn't notice. So be aware that there is a difference and it'll be okay I think!
In android studio i have this layout.
I want the red ball bellow the layout to be move on the path .
The bath is an photo which I put it in background.
I search a lot but I do not found a way to do that.
I need an example or keywords I can search for it.
This is layout image
I don't have the experience to work with your plan but you can see the answers to the link below.
I hope useful for you :)

Anyone know how can i achieve a list like this in the picture? I want to add the images in the project, and create a layout that will pick them up and put them automatically in the layout. Not manually to import all images in the layout.
So like this if i add a new image in the app then it will be picked automatically.
I didnt try anything yet as am not sure how to do it.
All i found in the web is layouts with each row having 1 icon, but thats not what i want.
Any info or a link i can use anyone?
You just can't do that with a Spinner.
You need to use a GridView.
Normally we won't use TableLayout if there are so many images, which will cause Out of Memory Error if too many images loaded. Use GridView instead, very easy and meet your requirements. Look into ApiDemos for some sample codes.
I managed to solve this. Here is the link that helped me out: http://iserveandroid.blogspot.com/2010/12/custom-gridview-in-dialog.html
I was reading the tutorial on Styling the Android toggle button here. The author asks us to create the 9patch drawable for both. I have trying to do this all morning, but have not been able to. Could anyone share the images with me, or tell me where i can get them ?
Kind Regards
You can find the 9patch drawable tool in the SDK folder in the tools folder.
It's a very useful tool for creating 9patch images, and you should be able to make your toggle button with it
There are links to 9-patches here: https://stackoverflow.com/a/15640365/2066079
The ones provided will style your togglebuttons to look like switches (which are only available in v14+)
I am looking to build a button in my Android app which must contain:
A background picture
A picture
Some text
I am coming from iPhone dev and I am a little bit confused by Android development.
While I could addSubView: UIImageView or UILabel to my UIButton, I can't use addView() with a android.widget.Button :(
Does anyone have a solution?
EDIT : Thanks everybody for answers. I forgot to specify I have to do it programmatically, without using XML. I don't know how many element I will display (it depends on RSS).
android:background for background ... remeber that you can build your own 9 patch
android:drawableLeft, android:drawableRight, android:drawableTop, android:drawableBottom to add some picture to the left, right, ... of text
EDIT: i didn't mention ... but i was talking about android.widget.Button
2nd EDIT: after you provide more information i think that all what you need is ListView
check this sample http://esilo.pl/LooserSample.zip (don't take "looser" to yourself, it was sample for another guy)
it showing how to
download a JSON data
store it in db
build ContentProvider for sharing a data
use ContentProvider to take data from db and show it in ListView
dynamic loading images from internet
for simpler sample use your sdk samples like this C:\android\android-sdk-windows\samples\android-8\ApiDemos\src\com\example\android\apis\view\List*.java
if you alrady have code for downloading and storing data from RSS in array extend ArrayAdapter to fit your needs
Most, if not all, of the UI for android is built in the XML. Kind of like the UI builder in Xcode, but not near as advanced. The ADP will let you view the UI you have built in Eclipse, and adjust some basic widget properties.
I believe for what you are trying to do, if I understand right, you need to use an ImageButton widget. This widget allows you to use a complete image as a button. You can also define your own states (button pressed, gain focus, etc) with both the button and image button widgets. You can define a background and add images to both widgets.
