Android Xstream
第一次写博客，应该能看
一，什么是xstream
Xstream是将java对象和XML互相转换的第三方架包。
本文使用的xstream版本是 1.4.7版本 【注：因xstream已经放入studio库中这里就不提供第三方包地址了】
废话不多说，代码是最好的解释：
MainActivity的xml布局就写了一个TextView， 很是简单我这里就不写了
MainActivity
public class MainActivity extends AppCompatActivity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
TextView textView=(TextView) findViewById(R.id.tv_Data);
MyTfrxReport myReport= XmlUtils.getObject(str, MyTfrxReport.class);
MyTfrxReportPage myPage=XmlUtils.getObject(strin,MyTfrxReportPage.class);
String mTfrxPictureView="";
String mTfrxMemoView="";
for (int i=0;iXmlUtils.class
public class XmlUtils {
public static String XMLHEADER = "";
private static XStream xstream = null;
/**
* 将xml解析成指定泛型并返回
* xml转换为类（java）（对象）
*/
public static T getObject(String string, Class clazz) {
XStream xstream = new XStream(new DomDriver());
xstream.processAnnotations(clazz);
xstream.ignoreUnknownElements();
return (T) xstream.fromXML(string);
}
/**
* 将指定类变成XML型数据返回
* 指定类（java）转换为xml
*/
public static String getData(Object object, Class cls) {
XStream xstream = new XStream();
xstream.processAnnotations(cls);
xstream.ignoreUnknownElements();
return xstream.toXML(object);
}
/**
* 特殊字符替换
* strData String 原始字符串
* regex String 要替换的字符串
* replacement String 替代字符串
* XmlUtils.replaceString(XmlUtils.getData(dataRoot, SaveDataRoot.class), "__", "_");
*/
public static String replaceString(String strData, String regex, String replacement) {
if (strData == null) {
return null;
}
int index;
index = strData.indexOf(regex);
String strNew = "";
if (index > 0) {
while (index >= 0) {
strNew += strData.substring(0, index) + replacement;
strData = strData.substring(index + regex.length());
index = strData.indexOf(regex);
}
strNew += strData;
return strNew;
}
return strData;
}
public static String decodeString(String strData) {
strData = replaceString(strData, "<", "<");
strData = replaceString(strData, ">", ">");
strData = replaceString(strData, "'", "'");
strData = replaceString(strData, """, "\"");
strData = replaceString(strData, "&", "&");
return strData;
}
