how to get Theme attributes values

Question

Is it possible to obtain styled attributes values from particular Theme without setting the theme up to application/activity? (I mean before invoking context.setTheme(..))

TypedArray a = getTheme().obtainStyledAttributes(R.style.ThemeName, new int[] {R.attr.attribute_name}); — Kid24

Don't forget a.recycle()! Reference: stackoverflow.com/questions/7252839/… — KitKat

For example, to get editTextColor attribute's value of a theme called MyTheme:

TypedArray a = getTheme().obtainStyledAttributes( R.style.MyTheme, new int[] { R.attr.editTextColor }); // Get color hex code (eg, #fff) int intColor = a.getColor(0 /* index */, 0 /* defaultVal */); String hexColor = Integer.toHexString(intColor); // Don't forget to recycle a.recycle();

...and if you are looking for a way to also get the themes style resource id dynamically see here: stackoverflow.com/a/9537629/317889
You should call a.recycle() when you're done with the TypedArray.

JavaDoc:

method TypedArray android.content.res.Resources.Theme.obtainStyledAttributes(int[] attrs)

Return a TypedArray holding the values defined by Theme which are listed in attrs.

Be sure to call TypedArray.recycle() when you are done with the array.

What happens, if not? E.g. because I leave the function scope?

if you need it in the xml file, you can use something like this:

style="?android:attr/panelTextAppearance"

for example:

<TextView style="?android:attr/panelTextAppearance" android:paddingTop="?android:attr/paddingTop" android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="@string/your_text" />

if you're using eclipse, control+click on the item, to see other possible values (a file attrs.xml will open).
