Hi,

I got my ListView which shows one ImageView and two TextViews in every row.

Now I want to load the images NOT from my ressources (as in many examples) but from the internet.

Somehow this doesnt work with the SimpleAdapter. Is this a bug?

Here comes my code:

---------------------------------------------------------------------------

MEINUNGEN.XML:

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical" android:layout_width="fill_parent"
android:layout_height="fill_parent" android:background="@drawable/bg">

<ListView android:id="@+id/android:list" android:layout_width="fill_parent"
android:layout_height="fill_parent" android:cacheColorHint="#00000000"
android:divider="@drawable/divider" android:dividerHeight="1px"/>

</LinearLayout>

---------------------------------------------------------------------------

MEINUNGEN_LIST_ROW.XML:

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent" android:layout_height="wrap_content"
android:orientation="horizontal" android:paddingTop="3dip"
android:paddingBottom="3dip" android:paddingLeft="3dip">

<ImageView android:id="@+id/icon" android:layout_width="wrap_content"
android:layout_height="wrap_content" android:layout_gravity="center_vertical"
android:src="@drawable/wolfgangroth" />

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent" android:layout_height="fill_parent"
android:orientation="vertical">

<TextView android:id="@+id/name" android:text="Thomas Öchsner"
android:textSize="10px" android:gravity="center_vertical"
android:paddingLeft="6dip" android:paddingTop="6dip"
android:textColor="#cccccc" android:layout_width="fill_parent" android:layout_height="wrap_content"/>

<TextView android:id="@+id/content" android:text="Dämpfer für von der Leyen"
android:textSize="16px" android:gravity="center_vertical"
android:paddingLeft="6dip" android:paddingTop="6dip"
android:textColor="#eeeeee" android:layout_width="fill_parent" android:layout_height="wrap_content"/>

</LinearLayout>

</LinearLayout>

---------------------------------------------------------------------------

public class MeinungenListActivity extends ListActivity {

private static final String ICON = "icon";
private static final String NAME = "name";
private static final String CONTENT = "content";
private static final String INTENT = "intent";
private static final String[] PARAM = { ICON, NAME, CONTENT };

private List<Map<String, Object>> list = new ArrayList<Map<String, Object>>();

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

setContentView(R.layout.meinungen);

addItem(list, R.drawable.thomasoechsner, "Thomas Öchsner",
"Dämpfer für von der Leyen", new Intent(this,
MeinungenListActivity.class));

addItem(list, R.drawable.marcbeise, "Marc Beise",
"Die Banker ducken sich schon wieder weg", new Intent(this,
MeinungenListActivity.class));

addItem(list, R.drawable.wolfgangroth, "Wolfgang Roth",
"Röttgen setzt auf Angriff", new Intent(this,
MeinungenListActivity.class));

addItem(list, R.drawable.charlottefrank, "Charlotte Frank",
"Sorge um die Vorsorge", new Intent(this,
MeinungenListActivity.class));

SimpleAdapter notes = new SimpleAdapter(this, list, R.layout.meinungen_list_row, PARAM, new int[] { R.id.icon, R.id.name, R.id.content });
setListAdapter(notes);
}

public void addItem(List<Map<String, Object>> data, int icon, String name, String content, Intent intent) {
Map<String, Object> map = new HashMap<String, Object>();
map.put(ICON, icon);
map.put(NAME, name);
map.put(CONTENT, content);
map.put(INTENT, intent);
data.add(map);
}

---------------------------------------------------------------------------

THIS CODE IS THE PROBLEM (please look at "here_comes_it"):

public void addItem(List<Map<String, Object>> data, Bitmap here_comes_it, String name, String content, Intent intent) {
Map<String, Object> map = new HashMap<String, Object>();
map.put(ICON, here_comes_it);
map.put(NAME, name);
map.put(CONTENT, content);
map.put(INTENT, intent);
data.add(map);
}


try {
URL aURL = new URL("http://www.anddev.org/images/avatars/6748766294aa15a585d1fd.jpg");
URLConnection conn = aURL.openConnection();
conn.connect();
InputStream is = conn.getInputStream();
Bitmap here_comes_it = BitmapFactory.decodeStream(is);
is.close();

addItem(list, here_comes_it, "Daniela Kuhr", "Angst vor der Genknolle", new Intent(this, MeinungenListActivity.class));
} catch (Exception e) {
e.printStackTrace();
}

Hey Darolla, can I ask you something? I believe that "data" in your ViewBinder is a map item? I have a similar problem to yours just that I don't only have 1 image that I have to get from the web. I'm thinking that I may have to use for-loop to iterate through the entire list of urls that I'm using an then setting the images into the imageviews inside the list. Do you have any idea how? Thanks

Hey,Darolla. very honored to see your share
i'm a chinese beginners and i was also met the problem.
so.thank you very much.
But :
if( (view instanceof ImageView) & (data instanceof Bitmap) )
Why did you don't make use of "&&" ? Guo
