I have a code that just don't work! The AsyncTask needs to return a TreeMap < Integer, List< String > > but through my logging i see it doesn't. It just stucks!
Here is the code:
private class ParseSite extends
AsyncTask<String, Void, Map<Integer,List<String>>> {
Map<Integer,List<String>> quotes;
List<String> tmpInfo;
List<String> tmpText;
@Override
protected Map<Integer,List<String>> doInBackground(String... arg) {
// List<String> output = new ArrayList<String>();
quotes = new TreeMap<Integer,List<String>>();
try {
HTMLHelper hh = new HTMLHelper(new URL(arg[0]));
List<TagNode> qText = hh.getContentByClass("content");
Logger.l(Logger.TAG_DBG, "GOT qText");
List<TagNode> qInfo = hh.getContentByClass("sm");
Logger.l(Logger.TAG_DBG, "GOT qInfo");
tmpInfo = new ArrayList<String>();
tmpText = new ArrayList<String>();
for (Iterator<TagNode> iterator = qText.iterator(); iterator
.hasNext();) {
TagNode divElement = iterator.next();
String tmp = divElement.getText().toString();
tmp = tmp.replaceAll("<", "<");
tmp = tmp.replaceAll(">", ">");
tmp = tmp.replaceAll(""", "" + (char) 34);
tmpText.add(tmp);
Log.i(Logger.TAG_INF, tmp);
}
Logger.l(Logger.TAG_DBG, "tmpText[" + tmpText.size() + "] Filled");
quotes.put(1, tmpText);
for (Iterator<TagNode> iterator = qInfo.iterator(); iterator
.hasNext();) {
TagNode divElement = iterator.next();
String tmp = divElement.getText().toString();
tmpInfo.add(tmp);
Log.i(Logger.TAG_INF, tmp);
}
Logger.l(Logger.TAG_DBG, "tmpInfo[" + tmpInfo.size() + "] Filled ");
quotes.put(2, tmpInfo);
Logger.l(Logger.TAG_DBG, "quotes Filled");
} catch (Exception e) {
e.printStackTrace();
}
Logger.l(Logger.TAG_DBG, "Returning quotes...");
return quotes;
}
@SuppressWarnings("unused")
protected void onPostExecute(List<String> output) {
pd.dismiss();
Logger.l(Logger.TAG_DBG, "Setting adapter...");
listView.setAdapter(new QuotesArrayAdapter(HTMLParser.this,
quotes));
}
}
Through LogCat i can see my "Returning quotes..." but i can't see "Setting adapter..." and the ProgressDialog pd does not dismiss.
BTW sorry for my bad english. I'm russian.
The compiler is warning you, but you choose to ignore it:
@SuppressWarnings("unused")
The compiler knows this method is never used, because you've declared it wrong. Change it to:
@Override
protected void onPostExecute(Map<Integer,List<String>> output) {
pd.dismiss();
Logger.l(Logger.TAG_DBG, "Setting adapter...");
listView.setAdapter(new QuotesArrayAdapter(HTMLParser.this,
quotes));
}
Notice the type of the parameter, and the @Override
annotation. Using this annotation will ensure you overrode methods correctly by giving an error if you didn't.
