android - How to prevent TextView font changing, when we change the Device font style in Samsung devices

Question

I would like say that I have a strange problem in setting textview font. If I change the Device font style from setting-> display, then textview font style also get changed. How can i prevent this?

Here is my textview in my xml layout.

<TextView
        android:id="@+id/textView1"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:layout_gravity="center"
        android:background="@drawable/title_bar_bg"
        android:fontFamily="sans-serif"
        android:typeface="sans"
        android:gravity="center"
        android:text="@string/people_finder"
        android:textColor="@color/WHITE"
        android:textSize="18sp"
        android:textStyle="bold"/>

android:fontFamily="sans-serif" android:typeface="sans"

Also It is working fine in some device like Samsung Galaxy Grand, Samsung Note 2. But not working in Samsung Note 8, Samsung Note 10.1 etc.

is there any other way to do this?

Thanks

fontFamily and typeface attributes are related to android native fonts. If you want your TextViews font to be always the same regardless the device font settings, you need to programmatically set a custom Typeface.

Typeface tf = Typeface.createFromAsset(context.getAssets(), "fontName.ttf"));
TextView textView = (TextView) findViewById(R.id.textView1);
textView.setTypeface(tf);

As a side note, Calligraphy project enables actually setting custom font directly from a layout xml.
