网络获取信息Ion---解析xml和assets获取信息pull解析xml

两个包androidasync-2.1.6.jar-------ion-2.1.6.jar

配置--android.permission.INTERNET

Mainactivity

获取网络信息

String ulr = "http://www.oschina.net/action/api/news_list?catalog=1&pageIndex="+ pageIndex + "&pageSize=20";

Ion.with(getApplicationContext()).load(ulr).asString()

.setCallback(new FutureCallback<String>() {

//result就是解析

@Override

public void onCompleted(Exception e, String
result) {

// TODO Auto-generated method stub

if (e != null) {

return;

}

pull(result);

allList.addAll(nList);

adapter.addrest(allList);

}

});
