Answer 1

public class Test extends Activity {

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);

        Button but = (Button) findViewById(R.id.button1);
        but.setText( formatString( "Line 1\nLine 2" ) );
    }

    private Spannable formatString(String str) {
        int startSpan = str.indexOf("\n");
        int endSpan   = str.length();

        Spannable spanString = new SpannableString(str);

        spanString.setSpan(new TextAppearanceSpan(this,
                R.style.custompoint), startSpan, endSpan,
                Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);

        return spanString;
    }
