这是从服务器返回的数据流。。。直接解析数据流
|
|
这个自己百度一下有很多的 直接给代码的话没人时间帮你去做,而且自己做的话效果更好,你可以在做的过程中把遇到的不能解决问题发出来
|
|
package com.bill99.kuaiqian;
import java.io.InputStream; import java.util.ArrayList; import java.util.List; import org.xmlpull.v1.XmlPullParser; import android.util.Xml; } } |
|
已经做了，但是最后输出的结果是空值，不知道啥情况
|
|
不要直接发代码 用代码格式发 不然看不清楚 例如:
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);

updateinfo=null;
}
}
type=xmlPullParser.next();
}
return updateinfolist;
}
}
|
|
type=xmlPullParser.next(); 除了 留下58行的 全部干掉 |
|
赋值不要使用gettext() 使用xmlPullParser.nextText();

求大神啊。。。。怎么解决

大神，如果这个方法有参数呢
public List<msgContent> parse(String result){}
就像这样的，下面那个setInput又怎么办呢？？ 谢谢你啊先给分给你 |
50分 |
public void xml(int id) throws XmlPullParserException, IOException{
String str = "";
XmlPullParser xmlPullParser= Xml.newPullParser();
xmlPullParser.setInput(getResources().openRawResource(id),"UTF-8");
就这样吧他需要的参数传递进去就ok |
|
还有个问题啊，比如我有个字符串result，在主mainactivity中调用这个方法的时候怎么调用啊
|
|
你好 问题解决了么 不好意思 我下班一般不上CSDN的 |
|
没事没事。问题没解决呢，按照你的方法，里面的是方法参数是int类型啊，可是我调用这个方法处理的是数据流或者string字符串，这个该如何解决呢，后来按照我之前的写的，存入list中，
下面是我代码， public class msgContent {
private String appVersion;
private String latestAppVersion;
private String latestAppVersionUrl;
private String appType;
private String appFlag;
private String responseCode;
public msgContent() {
}
public msgContent(String appVersion,String latestAppVersion, String latestAppVersionUrl,
String appType,String appFlag,String responseCode){
this.appFlag=appFlag;
this.appType=appType;
this.appVersion=appVersion;
this.latestAppVersion=latestAppVersion;
this.latestAppVersionUrl=latestAppVersionUrl;
this.responseCode=responseCode;
}
public String getResponseCode() {
return responseCode;
}
public void setResponseCode(String responseCode) {
this.responseCode = responseCode;
}
public String getAppVersion() {
return appVersion;
}
public void setAppVersion(String appVersion) {
this.appVersion = appVersion;
}
public String getLatestAppVersion() {
return latestAppVersion;
}
public void setLatestAppVersion(String latestAppVersion) {
this.latestAppVersion = latestAppVersion;
}
public String getLatestAppVersionUrl() {
return latestAppVersionUrl;
}
public void setLatestAppVersionUrl(String latestAppVersionUrl) {
this.latestAppVersionUrl = latestAppVersionUrl;
}
public String getAppType() {
return appType;
}
public void setAppType(String appType) {
this.appType = appType;
}
public String getAppFlag() {
return appFlag;
}
public void setAppFlag(String appFlag) {
this.appFlag = appFlag;
}
}
public class UpdateInfoParser extends Activity implements MessageParse { @Override
public List<msgContent> parse(InputStream inStream) throws Exception {
List<msgContent> updateinfolist=null;
msgContent updateinfo=null;
XmlPullParser xmlPullParser= Xml.newPullParser();
xmlPullParser.setInput(inStream,"UTF-8");
int type=xmlPullParser.getEventType();
while(type!=XmlPullParser.END_DOCUMENT){
switch (type) {
case XmlPullParser.START_DOCUMENT:
{
updateinfolist =new ArrayList<msgContent>();
}
break;
case XmlPullParser.START_TAG:
String tag=xmlPullParser.getName();
updateinfo=new msgContent();
if(tag.equalsIgnoreCase("latesAppVersion")){
updateinfo.setAppType(xmlPullParser.nextText());
}else if(tag.equalsIgnoreCase("appVersion")){
updateinfo.setAppVersion(xmlPullParser.nextText());
}if(tag.equalsIgnoreCase("responseCode")){
updateinfo.setResponseCode(xmlPullParser.nextText());
}if(tag.equalsIgnoreCase("appFlag")){
updateinfo.setAppFlag(xmlPullParser.nextText());
}if(tag.equalsIgnoreCase("appType")){
updateinfo.setAppType(xmlPullParser.nextText());
}if(tag.equalsIgnoreCase("latestAppVersionUrl")){
updateinfo.setLatestAppVersionUrl(xmlPullParser.nextText());
}
break;
case XmlPullParser.END_TAG:
if(xmlPullParser.getName().equalsIgnoreCase("appInfo")){
updateinfolist.add(updateinfo);
updateinfo=null;
}
}
type=xmlPullParser.next();
}
return updateinfolist;
}
}

现在我主函数有个input数据流，或者一个string字符串想调用这个方法，应该怎么调用？？
|
|
UpdateInfoParser updateInfoParser=new UpdateInfoParser(); List<msgContent> b=updateInfoParser.parse(input); 我这样调用，想获取list中的值，总是报空，大神有办法么 |
|
汗 刚才有点忙 没时间上csdn 现在才看到你消息,你加我扣 扣吧 469534249 |
