The data I retrieved from web server is not displaying in my listview due to the the special characters. For one of the example I retrieved, the data is: ****Two strategies to be shared <p>
A) Company selection <p>
** In this case, it only display till "Two strategies to be shared". May I know any suggestions for me to do it? I tried regex but I'm not sure how should I implement it in my file. This is my coding:
package com.example.fambond;
import java.util.ArrayList;
import java.util.HashMap;
import org.w3c.dom.Document;

public class AndroidXMLParsingActivity extends ListActivity {

String regex = "</{0,1}.+?>";
String replacement = "";
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
final ArrayList<HashMap<String, String>> menuItems = new ArrayList<HashMap<String, String>>();
XMLParser parser = new XMLParser();
String xml = parser.getXmlFromUrl(URL); // getting XML
Document doc = parser.getDomElement(xml); // getting DOM element
NodeList nl = doc.getElementsByTagName(KEY_EVENT);
// looping through all item nodes <item>
for (int i = 0; i < nl.getLength(); i++) {
// creating new HashMap
HashMap<String, String> map = new HashMap<String, String>();
Element e = (Element) nl.item(i);
// adding each child node to HashMap key => value
map.put(KEY_TITLE, parser.getValue(e, KEY_TITLE));
map.put(KEY_URL, parser.getValue(e, KEY_URL));
map.put(KEY_DESC, "Description: " + parser.getValue(e, KEY_DESC));
map.put(KEY_START_TIME, parser.getValue(e, KEY_START_TIME));
map.put(KEY_STOP_TIME, parser.getValue(e, KEY_STOP_TIME));
map.put(KEY_VENUE_NAME, parser.getValue(e, KEY_VENUE_NAME));
map.put(KEY_COUNTRY_NAME, parser.getValue(e, KEY_COUNTRY_NAME));
// adding HashList to ArrayList
menuItems.add(map);
}
// Adding menuItems to ListView
ListAdapter adapter = new SimpleAdapter(this, menuItems,
R.layout.list_item, new String[] { KEY_TITLE, KEY_DESC, KEY_COUNTRY_NAME,
KEY_VENUE_NAME, KEY_START_TIME }, new int[] {
R.id.title, R.id.description, R.id.countryName, R.id.venueName,
R.id.startTime });
setListAdapter(adapter);
// selecting single ListView item
ListView lv = getListView();
lv.setOnItemClickListener(new OnItemClickListener() {
@Override
public void onItemClick(AdapterView<?> parent, View view,
int position, long id) {
// getting values from selected ListItem
String title = ((TextView) view.findViewById(R.id.title))
.getText().toString();
HashMap<String, String> description = menuItems.get(position);
// Starting new intent
Intent in = new Intent(getApplicationContext(),
SingleMenuItemActivity.class);
in.putExtra(KEY_TITLE, title);
in.putExtra(KEY_DESC, description);
startActivity(in);
}
});
}
}
Any suggestions on how should I solve this problem?
Try spannable string builder. It will retain content and markup of your string and you will be able to display these special characters.
http://developer.android.com/reference/android/text/SpannableStringBuilder.html
Example:
SpannableStringBuilder stringBuilder = new SpannableStringBuilder();
stringBuilder.append(text);
Now in your ListView text just put it like this
textView.setText(stringBuilder);
