Adam,
I am not sure about the extra indirection level you have in your code
(the "?attr" stuff), but this should work:
<declare-styleable name="MainSplash">
<attr name="splashDrawable" format="reference" />
</declare-styleable>
<style name="Theme.MyCustomTheme" parent="@android:style/Theme">
<item name="splashDrawable">@drawable/splash</item>
</style>
With this in the manifest:
<activity ..... android:theme="@style/Theme.MyCustomTheme" ... />
And then:
TypedArray a =
this.obtainStyledAttributes(R.styleable.MainSplash);
Drawable d1 =
a.getDrawable(R.styleable.MainSplash_splashDrawable);
a.recycle();
BTW, you can put all this xml stuff in one file - the name doesn't
matter, as long as it's inside res/values.

Ok, I have the following files: attrs.xml, styles.xml, themes.xml
Here is my attrs.xml file:
<!-- Attributes -->
<attr name="myMainSplashImage" format="reference"/>
<declare-styleable name="MainSplash">
<attr name="splashDrawable" format="reference"/>
</declare-styleable>
Here is my themes.xml file:
<style name="Theme.MyCustomTheme" parent="@android:style/
Theme">
<item name="myMainSplashImage">@drawable/splash</item>
</style>
Here is my styles.xml file:
<style name="MainSplash">
<item name="splashDrawable">?attr/myMainSplashImage</item>
</style>
I have looked at different tutorials and libraries (GreenDroid) to
implement the above.
So I have basically set my custom attribute to whatever I have defined
in my Theme file. This allows me to create different theme files for
different projects (as this is a library project).
I have assigned the Theme to the entire library project. I dont know
if I now have to assign something else to my splash layout file?

Where and how are you setting attribute values?
Your call to getStylableAttributes is looking for attribute values in
the activity's theme, is that where you've specified your values?

Hey,
Ive been looking into getting Custom Attributes working within an
application. I have this working up to the point where I am able to
assign the custom attribute via XML to one of my Views (a Background
or Image Source for example).
What I now want to do is access the Custom Attributes via Code, within
my Activity. I am not implementing custom Views here. I am just
wanting to access, within my Activity, the custom attributes that I
have defined. I will use these to programatically change the look of
my List View based on certain criteria.
Is there a way I can do this? I have the following code, but it does
not work, returns null each time. The code is just a test to assign a
background of the splash programatically.
@Override
public void onCreate(Bundle icicle) {
super.onCreate(
setContentView(R.layout.splash);
TypedArray a =
getApplicationContext().obtainStyledAttributes(R.styleable.MainSplash);
int i =
a.getResourceId(R.styleable.MainSplash_splashDrawable, 0);
}
I always get returned '0' when using the above code. Any ideas?
