Android：如何为不同的URL解析不同按钮的RSS Feed(Android: How to parse RSS Feed for different button for different URL)

我在我的应用程序中粘贴RSS Feed，当我只解析一个然后它运行正常但我有8个不同的URL地址想要设置按钮，我想解析每个按钮点击RSS Fedd。我正在使用SAX Parser。 我的代码如下

BaseFeedParser.java

package com.example.shareslab; import java.io.IOException; import java.io.InputStream; import java.net.MalformedURLException; import java.net.URL; import java.util.ArrayList; import java.util.List; import com.example.shareslab.Message; import android.sax.Element; import android.sax.EndElementListener; import android.sax.EndTextElementListener; import android.sax.RootElement; import android.util.Xml; public class BaseFeedParser { static String feedUrlString = "http://www.xxxx.com/rss.xml"; // names of the XML tags static final String RSS = "rss"; static final String CHANNEL = "channel"; static final String ITEM = "item"; static final String PUB_DATE = "pubDate"; static final String DESCRIPTION = "description"; static final String LINK = "link"; static final String TITLE = "title"; private final URL feedUrl; protected BaseFeedParser(){ try { this.feedUrl = new URL(feedUrlString); } catch (MalformedURLException e) { throw new RuntimeException(e); } } protected InputStream getInputStream() { try { return feedUrl.openConnection().getInputStream(); } catch (IOException e) { throw new RuntimeException(e); } } public List<Message> parse() { final Message currentMessage = new Message(); RootElement root = new RootElement(RSS); final List<Message> messages = new ArrayList<Message>(); Element itemlist = root.getChild(CHANNEL); Element item = itemlist.getChild(ITEM); item.setEndElementListener(new EndElementListener(){ @Override public void end() { messages.add(currentMessage.copy()); } }); item.getChild(TITLE).setEndTextElementListener(new EndTextElementListener(){ @Override public void end(String body) { currentMessage.setTitle(body); } }); item.getChild(LINK).setEndTextElementListener(new EndTextElementListener(){ @Override public void end(String body) { currentMessage.setLink(body); } }); item.getChild(DESCRIPTION).setEndTextElementListener(new EndTextElementListener(){ @Override public void end(String body) { currentMessage.setDescription(body); } }); item.getChild(PUB_DATE).setEndTextElementListener(new EndTextElementListener(){ @Override public void end(String body) { currentMessage.setDate(body); } }); try { Xml.parse(this.getInputStream(), Xml.Encoding.UTF_8, root.getContentHandler()); } catch (Exception e) { throw new RuntimeException(e); } return messages; } }

我有8个按钮和8个RSS Feed的URL地址，我想解析每个按钮的每一个

MessageList.java

package com.example.shareslab; import java.util.ArrayList; import java.util.Arrays; import com.example.shareslab.R; import android.app.ListActivity; import android.content.Context; import android.content.Intent; import android.os.Bundle; import android.view.LayoutInflater; import android.view.View; import android.view.View.OnClickListener; import android.view.ViewGroup; import android.widget.AdapterView; import android.widget.AdapterView.OnItemClickListener; import android.widget.BaseAdapter; import android.widget.Button; import android.widget.ImageView; import android.widget.ListView; import android.widget.TextView; public class MessageList extends ListActivity implements OnClickListener { Button home,socialmedia,tech,usworld,business,fashion,people,political; public static String singleDescription; public static String title,URLToPost,imageURL; public static ArrayList<String> galleryImages; private static class EfficientAdapter extends BaseAdapter { private LayoutInflater mInflater; public EfficientAdapter(Context context) { mInflater = LayoutInflater.from(context); } @Override public int getCount() { System.out.println("description COUNT : "+SplashActivity.description.size()); return SplashActivity.description.size(); } @Override public Object getItem(int position) { return position; } @Override public long getItemId(int position) { return position; } @Override public View getView(final int position, View convertView, ViewGroup parent) { ViewHolder holder; if (convertView == null) { convertView = mInflater.inflate(R.layout.inflate_list_item, null); holder = new ViewHolder(); holder.title = (TextView) convertView.findViewById(R.id.inflate_title); holder.des = (TextView) convertView.findViewById(R.id.inflate_description); holder.im= (ImageView) convertView.findViewById(R.id.inflate_image); convertView.setTag(holder); } else { holder = (ViewHolder) convertView.getTag(); } UrlImageViewHelper.setUrlDrawable(holder.im, SplashActivity.imageURLAmit.get(position),null); holder.title.setText(SplashActivity.titles.get(position)); holder.des.setText(SplashActivity.description.get(position)); return convertView; } public static class ViewHolder { TextView title,des; ImageView im; } } // close class Efficent adapter @Override public void onCreate(Bundle icicle) { super.onCreate(icicle); setContentView(R.layout.main); home=(Button)findViewById(R.id.buttonhome); socialmedia=(Button)findViewById(R.id.buttonsocial); tech=(Button)findViewById(R.id.buttontech); usworld=(Button)findViewById(R.id.buttonusworld); business=(Button)findViewById(R.id.buttonbusiness); fashion=(Button)findViewById(R.id.buttonfashion); people=(Button)findViewById(R.id.buttonpeople); political=(Button)findViewById(R.id.buttonpolitical); home.setOnClickListener(this); socialmedia.setOnClickListener(this); tech.setOnClickListener(this); usworld.setOnClickListener(this); business.setOnClickListener(this); fashion.setOnClickListener(this); people.setOnClickListener(this); political.setOnClickListener(this); ListView listView = getListView(); listView.setTextFilterEnabled(true); this.setListAdapter(new EfficientAdapter(this)); listView.setOnItemClickListener(new OnItemClickListener() { @Override public void onItemClick(AdapterView<?> parent, View view, int position, long id) { // When clicked, show a toast with the TextView text galleryImages=new ArrayList<String>(); singleDescription=SplashActivity.description.get(position); title=SplashActivity.titles.get(position); URLToPost=SplashActivity.link.get(position); imageURL=SplashActivity.imageURLAmit.get(position); System.out.println("ON CLICK URL: "+URLToPost); galleryImages.addAll(Arrays.asList(SplashActivity.arrays[position])); startActivity(new Intent(MessageList.this,MessageListDetail.class)); } }); } @Override public void onClick(View arg0) { // TODO Auto-generated method stub } }

I am pasring RSS Feed in my app when i parse only one then it run properly but i have 8 different URL address which want to set on buttons and i want to parse RSS Fedd for every button click.I am using SAX Parser. MY code is below

BaseFeedParser.java

package com.example.shareslab; import java.io.IOException; import java.io.InputStream; import java.net.MalformedURLException; import java.net.URL; import java.util.ArrayList; import java.util.List; import com.example.shareslab.Message; import android.sax.Element; import android.sax.EndElementListener; import android.sax.EndTextElementListener; import android.sax.RootElement; import android.util.Xml; public class BaseFeedParser { static String feedUrlString = "http://www.xxxx.com/rss.xml"; // names of the XML tags static final String RSS = "rss"; static final String CHANNEL = "channel"; static final String ITEM = "item"; static final String PUB_DATE = "pubDate"; static final String DESCRIPTION = "description"; static final String LINK = "link"; static final String TITLE = "title"; private final URL feedUrl; protected BaseFeedParser(){ try { this.feedUrl = new URL(feedUrlString); } catch (MalformedURLException e) { throw new RuntimeException(e); } } protected InputStream getInputStream() { try { return feedUrl.openConnection().getInputStream(); } catch (IOException e) { throw new RuntimeException(e); } } public List<Message> parse() { final Message currentMessage = new Message(); RootElement root = new RootElement(RSS); final List<Message> messages = new ArrayList<Message>(); Element itemlist = root.getChild(CHANNEL); Element item = itemlist.getChild(ITEM); item.setEndElementListener(new EndElementListener(){ @Override public void end() { messages.add(currentMessage.copy()); } }); item.getChild(TITLE).setEndTextElementListener(new EndTextElementListener(){ @Override public void end(String body) { currentMessage.setTitle(body); } }); item.getChild(LINK).setEndTextElementListener(new EndTextElementListener(){ @Override public void end(String body) { currentMessage.setLink(body); } }); item.getChild(DESCRIPTION).setEndTextElementListener(new EndTextElementListener(){ @Override public void end(String body) { currentMessage.setDescription(body); } }); item.getChild(PUB_DATE).setEndTextElementListener(new EndTextElementListener(){ @Override public void end(String body) { currentMessage.setDate(body); } }); try { Xml.parse(this.getInputStream(), Xml.Encoding.UTF_8, root.getContentHandler()); } catch (Exception e) { throw new RuntimeException(e); } return messages; } }

I have 8 button and 8 URL address of RSS Feed and i want to parse for every it for every button

我不确定它是否是正确的方法..我有一个类似的要求，根据按钮点击解析rss feed.Hope这有助于

I am not sure if its the right approach.. I had a similar requirement to parse rss feed based on button click.Hope this helps
