Android : Dynamic List View with Image and Text

To construct dynamic list view in android ( list values from a php server page  which contains image and text as list values ) .

Here I am using Jsoup to parse the HTML elements from server php page to get image and text values and display values in Listview :

        list=(ListView)findViewById(R.id.list);
        adapter=new LazyAdapter(this, mStrings,tStrings);
        list.setAdapter(adapter);
        list.setClickable(true);

    i copied your code into Eclipse and tried to get it to run. But it could not compile because
    things like Default.class were missing. Can you either provide the complete code as a zip file
    or post the complete code so that it works. if this is a library issue, then please provide
    which jar files one needs.

    The concepts you use are nice, but not much use if the user can’t get it to work.

      Peter ,
      Dafault.class–> You can define this class based on your functionality .

      Just download jsoup-1.4.1.jar , to parse the XML response and dynamically populate the ListView elements .
