Change the font of all text views

Question

Is there a way to change the fonts of all text views in the layout?

im is currently used to change fonts manually.

TextView txtAppName = (TextView) findViewById(R.id.txtAppName);

Typeface tf = Typeface.createFromAsset(getAssets(),
    "fonts/Existence-Light.otf");
txtAppName.setTypeface(tf);

EDIT: I edited the question to clarify my problem.

TextViews (my is "fonts/Qlassik_TB.ttf" ) :

@Override
protected void onCreate(Bundle savedInstanceState) {
    // Your stuff here...

    Typeface tf = Typeface.createFromAsset(this.getAssets(), "fonts/Qlassik_TB.ttf");

    ViewGroup myMostParentLayout = (ViewGroup) findViewById(R.id.frame_layout_most_parent);

    setFontToAllChilds(myMostParentLayout, tf);
}

private void setFontToAllChilds(ViewGroup myMostParentLayout, Typeface tf) {
    int childCount = myMostParentLayout.getChildCount();
    for (int i = 0; i < childCount; ++i) {
        View child = myMostParentLayout.getChildAt(i);

        if (child instanceof ViewGroup)
            setFontToAllChilds((ViewGroup) child, tf);
        else if (child instanceof TextView)                
            ((TextView) child).setTypeface(tf);
}
