Question

what I have now is a listView with 3 items in it: Audience, Choosing topics, and Interviewing strategies. I want to be able to save these items as strings to open url with associated item name in the path, but the problem comes when the path has a different item name than the one I have in the listview items; we have Audience, Choosing_topics, and Interviewing as their names. How would I go about dealing away with this conflict in name without changing the names of the url or the listViewItem? Should I refer to another string array to compare the value of the first string array to to retrieve the associated item in the new array? Here’s what I have as of now:

setListAdapter(new ArrayAdapter(this, R.layout.list_item, GREATESTHITS));
ListView lv = getListView();
lv.setTextFilterEnabled(true);

    lv.setOnItemClickListener(new OnItemClickListener() {
      public void onItemClick(AdapterView<?> parent, View view,
          int position, long id) {
          String text = (String) ((TextView)view).getText();
          ((GlobalVariables)getApplication()).setGlobalVariable(text);
     String str = DownloadText("http://www.jmu.edu/uwc/" + text + ".html"); 



static final String[] GREATESTHITS = new String[] {"Audience", "Choosing topics", "Interviewing Strategies"};

Answer 1

I’d say the best way to deal with this is to use objects. You create a model for each of your strings on your GREATESTHITS. You can then add another property for the url or whatever extra you want.

After that is created, you create and ArrayAdapter<YourTypeHere> and on the ListView you can set the adapter you just created.

After that on the ItemClickListener you can use this:

YourTypeHere item = (YourTypeHere) parent.getItemAtPosition(position);

there you have the object on the array, and you can access all the properties you’ve set for that object.

This seems a little bit overkill for only 3 items, but it is the right way to go.

On an easier approach you can set a HashMap<String, String> urlNames, add a hash with each text and it’s relative url. After that, on the listener you can do

String text = (String) ((TextView)view).getText();
      ((GlobalVariables)getApplication()).setGlobalVariable(text);
String str = DownloadText("http://www.jmu.edu/uwc/" + urlNames.get(text) + ".html");
