I've a Async task in a FragmentActivity i'm using jsoup to get the html for table what i found out so far is doInBackground() is not working i.e it is not getting the html from the website the same coding is working with activity but in fragmentactivity it is not?
public class MainActivity extends FragmentActivity implements ActionBar.TabListener {
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
new JsoupListView().execute();
// Initilization
viewPager = (ViewPager) findViewById(R.id.pager);
actionBar = getActionBar();
mAdapter = new TabsPagerAdapter(getSupportFragmentManager());
viewPager.setAdapter(mAdapter);
actionBar.setHomeButtonEnabled(false);
actionBar.setNavigationMode(ActionBar.NAVIGATION_MODE_TABS);
// Adding Tabs
for (String tab_name : tabs) {
actionBar.addTab(actionBar.newTab().setText(tab_name)
.setTabListener(this));
}
/**
* on swiping the viewpager make respective tab selected
* */
viewPager.setOnPageChangeListener(new ViewPager.OnPageChangeListener() {
@Override
public void onPageSelected(int position) {
// on changing the page
// make respected tab selected
actionBar.setSelectedNavigationItem(position);
}
@Override
public void onPageScrolled(int arg0, float arg1, int arg2) {
}
@Override
public void onPageScrollStateChanged(int arg0) {
}
});
}
@Override
public void onTabReselected(Tab tab, FragmentTransaction ft) {
}
@Override
public void onTabSelected(Tab tab, FragmentTransaction ft) {
// on tab selected
// show respected fragment view
viewPager.setCurrentItem(tab.getPosition());
}
@Override
public void onTabUnselected(Tab tab, FragmentTransaction ft) {
}
// Title AsyncTask
private class JsoupListView extends AsyncTask<Void, Void, Void> {
@Override
protected void onPreExecute() {
super.onPreExecute();
// Create a progressdialog
mProgressDialog = new ProgressDialog(MainActivity.this);
// Set progressdialog title
mProgressDialog.setTitle("Android Jsoup ListView Tutorial");
// Set progressdialog message
mProgressDialog.setMessage("Loading...");
mProgressDialog.setIndeterminate(false);
// Show progressdialog
mProgressDialog.show();
}
@Override
protected Void doInBackground(Void... params) {
// Create an array
arraylist = new ArrayList<HashMap<String, String>>();
try {
// Connect to the Website URL
Document doc = Jsoup.connect(url).get();
for (Element table : doc.select("table[id=Table3]")) {
// Identify all the table row's(tr)
for (Element row : table.select("tr:gt(0)")) {
HashMap<String, String> map = new HashMap<String, String>();
// Identify all the table cell's(td)
Elements tds = row.select("td");
// Identify all img src's
Elements imgSrc = row.select("img[src]");
// Get only src from img src
String imgSrcStr = imgSrc.attr("src");
// Retrive Jsoup Elements
// Get the first td
map.put("field0", tds.get(0).text());
//System.out.println(("check"+tds.get(0).text()));
// Get the second td
map.put("field1", tds.get(1).text());
// Get the third td
map.put("field2", tds.get(2).text());
// Get the image src links
map.put("flag", imgSrcStr);
// Set all extracted Jsoup Elements into the array
arraylist.add(map);
}
}
} catch (Exception e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
return null;
}
@Override
protected void onPostExecute(Void result) {
// Locate the listview in listview_main.xml
listview = (ListView) findViewById(R.id.listview);
// Pass the results into ListViewAdapter.java
adapter = new ListViewAdapter(MainActivity.this, arraylist);
// Set the adapter to the ListView
listview.setAdapter(adapter);
//listview.setAdapter(adapter);
// Close the progressdialog
mProgressDialog.dismiss();
}
}
The application is working but i can not see data from the site in the ListView.
Please point me out what is missing?
