TypeFace的spannable EditText

Question

有没有人知道如何从EditText获取spannable的TypeFace。

我有一个EditText：

    // Instantiate EditText noteContent//
    noteContent = (EditText) findViewById(R.id.noteContent);
   noteContent.setTypeface(Typeface.defaultFromStyle(Typeface.NORMAL));

我有一个spannable：

    if (id == R.id.italic) {

        int startSelection = noteContent.getSelectionStart();
        int endSelection = noteContent.getSelectionEnd();
        Spannable spannable = noteContent.getText();

        Typeface style = noteContent.getTypeface();

        if (style.equals(Typeface.defaultFromStyle(Typeface.ITALIC))) {

            spannable.setSpan(new StyleSpan(Typeface.ITALIC), startSelection, endSelection , 0);

        } else {

            StyleSpanRemover spanRemover = new StyleSpanRemover();

            spanRemover.RemoveStyle(spannable, startSelection, endSelection, Typeface.ITALIC);
        }
    }

如果statment获得整个edittext的字体而不仅仅是spannable，问题是这个。如何获得spannable的当前字体？
