How to put line break in direct xml textview?

Use the escape character \n :

android:text="linha1\nlinha2\nlinha3"

You can add HTML tags to a text of your strings.html

follows an example:

strings.html

 <string name="minha_receita_1"> <![CDATA[ <ul> <li>1 caneca ou bule</li> <li>1 garrafa térmica</li> <li>1 colher (sopa)</li> <li> 1 coador de café</li> </ul> ]]> </string>

Content html should be between <![CDATA[ ]]>

In Java, do the following:

     TextView textHtml = TextView.class.cast(convertView.findViewById(R.id.receita));
    final Spanned textoEmHtml = Html.fromHtml( getContext().getString(R.string.minha_receita_1));
    textHtml.setText(textoEmHtml);
