ListView and List Adapter

Postby radhika » Thu May 15, 2008 2:11 pm

Hi PlusMinus,

I can't get a hold of the ListView and ListAdapter.

1)Is it that if we use a ListView we should use ListAdapter?
2)How can i call a listener when the item in a list is clicked?
3)Also i have created a listview.xml that creates a list view and array.xml that gives the items to the list. how can i refer that items name inside the java code?
4)To use a listener method for the ListView should the ListAdapter be necessarily used?

Please help me out!!! :?:

Please clear my doubts through a tutorial.

Thanks in Advance.
Thank you

Hello radhika,

1. yes (should not must)
2. Use OnItemClickListener, like:
Syntax: [ Download ] [ Hide ]
Using java Syntax Highlighting
  1.                 ListView lv = new ListView(this);
  3.                 lv.setOnItemClickListener(new ...)
Parsed in 0.011 seconds, using GeSHi

3. Code:
Syntax: [ Download ] [ Hide ]
Using java Syntax Highlighting
  1. ArrayAdapter<String> x = new ArrayAdapter<String>(this, ..., this.getResources().getStringArray(ResIdOfArray));
Parsed in 0.010 seconds, using GeSHi

4. No, the Adapter just fills in the items.

Noob question

So I'm just trying to figure out how to build the basic list! I have 3 items "Item 1, Item 2, Item 3" ive seen ListView mentioned and ListAdapter but I'm not sure how to get them to work together so i have a list of clickable items. So could someone show me a basic "Item 1, Item 2, Item 3" and when they are clicked just show a dialog saying "Item 1 clicked" then just an ok button etc.?
You gotta start somewhere :/

Making items non-selectable

I have a listview but I don't want items to be selectable (with no highlight).

How can I do that?
