adapter

I am a beginner and facing a problem where I am creating a ListView with two RadioButton s and a TextView . Everything goes fine, but when I set RadioButton s and scroll it, the values of previous RadioButton s change their values or lose their state dramatically. I am trying to solve this problem for long time. What changes should I make to overcome this problem? MainActivity.java public class MainActivity extends Activity { private ListView listView1; @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); Option

Could someone tell me how to make a good mechanism for async. download of images for use in a ListView/GridView? There are many suggestions , but each only considers a small subset of the typical requirements. Below I've listed some reasonable factors (requirements or things to take into account) that I, and my collegues, are unable to satisfy at once. I am not asking for code (though it would be welcome), just an approach that manages the Bitmaps as described. No duplication of downloaders or Bitmaps Canceling downloads/assigning of images that would no longer be needed, or are likely to be

I've got a strange problem that drives me crazy. In my android application I customized my own adapter that extends from ArrayAdapter. The items of the ListView to which I added my adapter can either be labeled-text (not editable), editable text or a spinner. The crazy stuff is: when I scroll the ListView, there are two problems: (1) the (selected) value that is shown in the spinner items changes sometimes although I only scrolled!! when I click on the spinner, the old selected value is still shown (the one, that should be shown by the spinner) (2) the order of the ListViewItems changes when I

I have downloaded one ImageDownloader code from gitHub( from Here ) Now when I am trying to download the image from my webservice I am getting this Runtime Exception "ImageLoader must be init with configuration before using".

And this my adapter: public class CustomAdapter extends BaseAdapter { private Context context; private ArrayList<String> logo_URL; private ListContent listContent; private ArrayList< TeamDataClass> teamdata = null; private ArrayList<EventDataClass> eventdata = null; private DisplayImageOptions options; private ImageLoader imageLoader;

I'm working on a android chatting application. When I called my api it returns me the chat list sorted by a user_id. But what I need to do is serialized by message_id as I want to show last message first.Here is my onBindViewHolder method in which i get the values. public void onBindViewHolder(final MyAdapter_HomeViewHolder holder, final int position) { holder.userNameTV.setText(data.get(position).getUserInfo().getFullName()); holder.msgBodyTV.setText(data.get(position).getBody()); holder.originator_iD.setText(data.get(position).getUserInfo().getId().toString()); //message ID. I need to

I have a class that implements the Enumeration<T> interface, but Java's foreach loop requires the Iterator<T> interface. Is there an Enumeration to Iterator Adapter in Java's standard library? Bozho You need a so called "Adapter", to adapt the Enumeration to the otherwise incompatible Iterator . Apache commons-collections has EnumerationIterator . The usage is: Iterator iterator = new EnumerationIterator(enumeration); If you just want something to iterate over in a for-each loop (so an Iterable and not only an Iterator), there's always java.util.Collections.list(Enumeration<T> e) (without
