Android Textview text size is different as set by XML and Java

Question

I get different text sizes when I set text size of a TextView by layout XML and Java code. My layout looks like the following.

<TextView
    android:id="@+id/title"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:text="Some text"
    android:textSize="18sp"/>

And I tried setting text size in Java by following two ways.

Option 1

TextView titleView = (TextView) view.findViewById(R.id.title);
titleView.setTextSize(18 * getResources().getDisplayMetrics().density);

Option 2

TextView titleView = (TextView) view.findViewById(R.id.title);
titleView.setTextSize(TypedValue.COMPLEX_UNIT_SP, 18);

The text size set by Java code (both option 1 and 2) appears much bigger than the text size set by layout XML. What am I doing wrong?

You will need to reduce the size by screen density

titleView.setTextSize(TypedValue.COMPLEX_UNIT_SP, (18 / getResources().getDisplayMetrics().density));

Thanks. Also found out that using `TypedValue.COMPLEX_UNIT_PX` instead of `TypedValue.COMPLEX_UNIT_SP` gives correct text size. – tilmik Oct 28 '15 at 18:08
