[android-developers] How to make a listview with only XML and no adapter
Hi! On one of my screens I want to have a list with only one item and I want to declare the item in XML since that's easier than writing a separate adapter . So i tried doing it without a ListView like in Code 1. The problem then is that selection isn't working like in the listview. I can't select the one row inside the linearlayout. So is there a way to declare the items in the listview directly in the XML? My screen looks like this: label textview1 textview 2 label image1 image2image3 And I want the user to be able to select the textviews or the images. Hope this was understandable :-) It's somewhat similar to the question asked here: http://www.mail-archive.com/android-developers@googlegroups.com/msg01647.html But the answer was do it in code... so does the same apply here? -Christer Code 1 LinearLayout xmlns:android=http://schemas.android.com/apk/res/android; android:orientation=horizontal android:layout_width=wrap_content android:layout_height=wrap_content android:gravity=right android:layout_gravity=right android:id=@+id/score_parent_layout TextView android:id=@+id/score_home android:layout_width=wrap_content android:layout_height=wrap_content android:gravity=right android:layout_gravity=right style=@style/LiveLineText android:layout_marginLeft=4px android:text=4 /TextView TextView android:id=@+id/score_separator android:layout_width=wrap_content android:layout_height=wrap_content android:gravity=right android:layout_gravity=right android:text= - style=@style/LiveLineText /TextView TextView android:id=@+id/score_away android:layout_width=fill_parent android:layout_height=wrap_content android:text=1 android:gravity=right android:layout_gravity=right android:paddingRight=8px style=@style/LiveLineText /TextView /LinearLayout --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Android Developers group.

[android-developers] Service not able to download network data while in standby
Hi! I have a service polling data at regular time intervals and this works great except when the phone goes into standby. Then the service never runs the timer thread and it never receives data. How does the SMS/ Email application do this since I get those notifications while in standby? When I did a Windows Mobile application this was just the same, and I had to resort to a third party timer (SDF) to solve this -Christer --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Android Developers group.

[android-developers] Parsing RSS feeds, encoding problems
Hi!
Does anyone have a working RSS parser with Android? I tried doing
simple DOM parsing of the XML but the character encoding isn't handled
properly so the norwegian characters aren't displayed. I have tried
everything but when I get the description element I just get the text
until the norwegian character. Any sample code of parsing
international RSS feeds would be very welcome!
Here is the feed that I am having problems with:
http://www.dagbladet.no/rss/fotball/
-Christer
Sample code that I started out with (have tried lots of encoding
tricks to no avail):
Feed feed = createFeed(this,
new
java.net.URI(http://www.dagbladet.no/rss/fotball/;));
...
public Feed createFeed(Context ctx, URI rssurl) {
Feed feed = new Feed();
try {
DocumentBuilder builder =
DocumentBuilderFactory.newInstance().newDocumentBuilder();
Document doc = builder.parse(rssurl.toURL().openStream());
NodeList nodes = doc.getElementsByTagName(item);
for (int i = 0; i nodes.getLength(); i++) {
Element element = (Element) nodes.item(i);
NodeList title = element.getElementsByTagName(title);
Element line = (Element) title.item(0);
String feedTitle = getCharacterDataFromElement(line);
String url = getCharacterDataFromElement
(element.getElementsByTagName(link).item(0));
Article art = new Article();
art.title = feedTitle;
art.url = url;
art.description = getCharacterDataFromElement
(element.getElementsByTagName(description).item(0));
feed.articles.add(art);
}
}
catch (Exception e) {
e.printStackTrace();
}
return feed;
}
public static String getCharacterDataFromElement(Node e) {
Node child = e.getFirstChild();
if(child == null)
return ?;
if (child instanceof CharacterData) {
CharacterData cd = (CharacterData) child;
return cd.getData();
}
return ?;
}

[android-developers] Setting gradient color of TextView creates problems with selection color
Hi!
I have a ListView with lines of TextViews (standings table for Premier
League).
In the first column I want to have a gradient so I have modified my
code like this:
//Top team should have a nice green color
if(position == 0)
{
toColor = Color.argb(255, 79, 191, 124);
grad = new GradientDrawable(Orientation.TOP_BOTTOM,
new int[]{Color.GREEN, Color.BLACK, Color.GREEN});
col0.setBackgroundDrawable(grad);
}
But the selector is not happy with this because the gradient is at the
top of the selector. I tried painting the selector at the top with
lv.setDrawSelectorOnTop(true);
But I couldn't get that to look any good. I also tried handling the
selectionChange property of the listview and setting background color
there but how can I clear the selection color when the listItem looses
selection? Do I have to loop through every item?
Are there any better ways of doing this?
Really appreciate any answers!
