Change the font of all the textviews in my application?

I wonder if there is a way to change the font of all the text views in an android application in single time ? By all the text views i mean programmatically or dynamically created text views and the text views created separately using XML layout files (Drag n drop)?

I know i can create a new theme with different required fonts and use it . But i can only see the theme applies to dynamically created text views within the program but not the one's in XML layout .

Can you please let me know if there is any solution for this or the only option is to change the font of each text view manually.

The easiest way is to extend the TextView widget:

public class FontTextView extends TextView {

private String mTypefacePath;

public FontTextView(Context context, AttributeSet attrs, int defStyle) {
    super(context, attrs, defStyle);
    setAttrs(context, attrs, defStyle);
    init(context);
}

public FontTextView(Context context, AttributeSet attrs) {
    super(context, attrs);
    setAttrs(context, attrs, 0);
    init(context);
}

public FontTextView(Context context) {
    super(context);
    init(context);
}

private void setAttrs(Context context, AttributeSet attrs, int defStyle) {
    if (isInEditMode())
        return;
    TypedArray a = context.obtainStyledAttributes(attrs, R.styleable.FontTextView, defStyle, 0);
    mTypefacePath = a.getString(R.styleable.FontTextView_typeface);
    a.recycle();
}

private void init(Context context) {
    if (!TextUtils.isEmpty(mTypefacePath)) {
        try {
            setTypeface(Typeface.createFromAsset(context.getAssets(),
                    mTypefacePath));
        } catch (Exception ex) {
            // could not create the typeface from path
        }
    } 
}}

You also need to define your typeface attribute. Take a look on this to see a useful explanation about.
