getText 與getString 區別

Android提供多種獲取資源文件方法，但是需要注意以下方法：

CharSequence getText(int resId)：返回本地、樣式化的字符。

String getString(int resId) ：返回字符串

/**
     * Return the string value associated with a particular resource ID.  The
     * returned object will be a String if this is a plain string; it will be
     * some other type of CharSequence if it is styled.
     * {@more}
     *
     * @param id The desired resource identifier, as generated by the aapt
     *           tool. This integer encodes the package, type, and resource
     *           entry. The value 0 is an invalid identifier.
     *
     * @throws NotFoundException Throws NotFoundException if the given ID does not exist.
     *
     * @return CharSequence The string data associated with the resource, plus
     *         possibly styled text information.
     */
    public CharSequence getText(int id) throws NotFoundException {
        CharSequence res = mAssets.getResourceText(id);
        if (res != null) {
            return res;
        }
        throw new NotFoundException("String resource ID #0x"
                                    + Integer.toHexString(id));
    }

/**
     * Return the string value associated with a particular resource ID.  It
     * will be stripped of any styled text information.
