You're not creating custom adapters, you just have four regular
ArrayAdapters (with the same data, it looks like).

You need something like:

class MyAdapter : ArrayAdapter
{
 @Override
 public View getView(int i, View v, ViewGroup vg)
 {
  switch (state)
  {
   case 1:
return createViewType1();
   case 2:
return createViewType2();
   case 3:
return createViewType3();
   case 4:
return createViewType4();
 }
}

Then, in your class:

setAdapter(new MyAdapter());

Then when you click your buttons you set "state" and implement the
"createView" functions to return the view you need in your ListView for that
given state. Or something. That's just one idea to get your rolling.

[Olivier Goutet]

I don't know if you can read French but there is a very good post on
this French blog: http://android.cyrilmottier.com/?p=232
It explain how to build a custom adapter (BaseAdapter in fact) to
manage 2 different types of cells on a list view. I hope the source
source code will be enough for you.

The ArrayAdapter you are using is just a very simple way to display
text cells on a listview.

To display your 4 different types of items, you will need to create 4
layout (1 for each cell type) and then inflate them in the base
adapter (as explained in the blog).

The "custom" part of an adapter is basically returning the View you want to
show in your list for a given item.

Currently you have the default ArrayAdapter that works on Strings. Since you
want something more complicated, all you have to do is create a class that
extends ArrayAdapter and override the getView() method to return the layouts
you want (as you described) based on the state of your list.

So the first thing to do is create your custom ArrayAdapter, override
getView, then set it as the adapter to your list and verify your views show
up as expected.

If anyone has time please try to help me out. Thanks, I looked into
some examples but really found it hard to see how I can have the
custom adapter runnning. Thanks

Ohh ok.Thanks. the format is changing in the sense that one of the
format is having a header to the same list items, another format is
having check boxes on left and another format is having two lines in
the same row for every list item. Thanks

[Kumar Bibek]

You are using the ArrayAdapter here. You have to use a custom adapter
which extends the ArrayAdapter or the BaseAdapter. Also, what format
are you trying to change? If you can give me an example, I can help
you with that.

[android-developers] Re: separate views list view

[Varun Khanduja]

Hi Kumar,

Thanks for the response. I think I am using custom adapter. Do you
have an example or some resource where i can see how to define this
method? Do you think I need on click event handlers? Was sort of
confused when checking google documentation. Thanks for guidance.

package com.varun.HelloListView;

import android.app.ListActivity;
import android.os.Bundle;
import android.view.Menu;
import android.widget.ArrayAdapter;
import android.widget.TextView;

public class HelloListView extends ListActivity {
TextView selection;

@Override
public void onCreate(Bundle icicle) {
super.onCreate(icicle);

setContentView(R.layout.main);
setListAdapter(new ArrayAdapter(this, R.layout.list_item,
R.id.label,AndroidPhones));
}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
super.onCreateOptionsMenu(menu);

menu.add(0, Settings.ENTER_FOOD, 0, "Enter Food");
menu.add(0, Settings.ANALYZE_FOOD, 0, "Analyze Food");
menu.add(0, Settings.SETTINGS, 0, "Settings");

return true;
}


static final String[] AndroidPhones = new String[] {
"HTC Evo 4G",  "Google Nexus One", "Motorola Devour",
"Motorola CLIQ", "Samsung Galaxy S", "Motorola Droid",
"myTouch 3G Slide", "Droid Eris", "Motorola Backflip",
"Motorola i1", "HTC Hero", "myTouch 3G Fender",
"HTC Droid Incredible",  "Samsung Moment", "LG Ally ",
};
}

[Kumar Bibek]

If you are using a custom adapter, you can have a method wherein you
specify a method to change the format of the ListView. Through this
event, you can change the dataset of the ListView and ask the list
view to reload all these items. Thats should serve the purpose.
