我有一个xml URL文件,其中有空格我想用%20替换空格..怎么做？???
SAXParserFactory spf = SAXParserFactory.newInstance();
SAXParser sp = spf.newSAXParser();
XMLReader xr = sp.getXMLReader();
/** Send URL to parse XML Tags */
URL sourceUrl = new URL(
"http://www.arteonline.mobi/iphone/output.php?gallery=MALBA%20-%20MUSEO%20DE%20ARTE%20LATINOAMERICANO%20DE%20BUENOS%20AIRES");
XMLHandlerartistspace myXMLHandler = new XMLHandlerartistspace();
xr.setContentHandler(myXMLHandler);
xr.parse(new InputSource(sourceUrl.openStream()));
我想知道确切的,
parcelable还是serialization技术将数据从一个活动发送到另一个活动？提前致谢.
public class GetSetClass implements Serializable {
private int dt = 10;

public void setDt(int dt) {
this.dt = dt;
}
}
