How to retrieve style attributes programmatically from styles.xml

by

It is possible to retrieve custom styles from styles.xml programmatically.

Define some arbitrary style in styles.xml:

<style name="MyCustomStyle">
    <item name="android:textColor">#efefef</item>
    <item name="android:background">#ffffff</item>
    <item name="android:text">This is my text</item>
</style>

Now, retrieve the styles like this

// The attributes you want retrieved
int[] attrs = {android.R.attr.textColor, android.R.attr.background, android.R.attr.text};

// Parse MyCustomStyle, using Context.obtainStyledAttributes()
TypedArray ta = obtainStyledAttributes(R.style.MyCustomStyle, attrs);

// Fetch the text from your style like this.     
String text = ta.getString(2);

// Fetching the colors defined in your style
int textColor = ta.getColor(0, Color.BLACK);
int backgroundColor = ta.getColor(1, Color.BLACK);

// Do some logging to see if we have retrieved correct values
Log.i("Retrieved text:", text);
Log.i("Retrieved textColor as hex:", Integer.toHexString(textColor));
Log.i("Retrieved background as hex:", Integer.toHexString(backgroundColor));

// OH, and don't forget to recycle the TypedArray
ta.recycle()
