getText 与getString 区别

Android提供多种获取资源文件方法，但是需要注意以下方法：

CharSequence getText(int resId)：返回本地、样式化的字符。
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.
* {@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 String The string data associated with the resource,
* stripped of styled text information.
*/
public String getString(int id) throws NotFoundException {
CharSequence res = getText(id);
if (res != null) {
return res.toString();
}
throw new NotFoundException("String resource ID #0x"
+ Integer.toHexString(id));
}
