I've been looking and I've seen several solutions but they all go through something out of
TextView , for example to use row separation and I use
\n there is not something similar to put a single word (or several different ones) in bold font?
In this case to try, put Text2 in bold.
<TextView android:text="Texto 1 \n Texto2 \n Texto3" android:layout_width="wrap_content" android:layout_height="wrap_content" android:id="@+id/textView" />
