hi guys,

I have gotten a little further on the project. It now gathers the input of the user, constructs the url, get the info and parses it, and displays the titles in a textview. Im just having trouble putting the titles in a listview so that once the user clicks a place it will display a map with the lat/long from that location.

Anyone know how i can get the items in a listview or if you can use a clicklistener on each different item in the textview? what would be easier.

Thanks,

Mg

Hi men,

I think that it is not difficult to list whatever U want in listview if U have one array. U can follow some sample in here

Hope help u.

Alex.

thanks alot for the article

You are a god!!

Hi everyone,

Just got a huge portion of the Local Search application working. Right now it is hard coded for my location (lat/long) but there is code in there that should populate the edittext on create. Could someone look at those and make sure it could work on a real phone? From there it takes the users input (food, bars, banks, etc) and brings up a list of businesses near that location. We just need to find a way to plot the lat/long of a specific business when it is clicked on a mapview. Any suggestions or comments will really help me improve this project. Thanks again for all the help so far!

I'm parsing this XML : http://www.google.com/ig/api?weather=Madrid,Spain without any problem; BUT with this : http://www.mercadolibre.com.ar/jm/searchXml?as_categ_id=1000&as_filtro_id=24_HS I get this error in the LogCat: "WARN/Pablo-ERR(1643): org.apache.harmony.xml.ExpatParser$ParseException: At line 4, column 21: not well-formed (invalid token)"

Whats wrong with this XML, and how can I solve it??

Thanks.-

Hi,
I'm trying to run this code but the end result shows:
ExtractedString =

The int works fine.

Im doing some logging and I see that somehow setExtractedString() gets called twice. The second time around the value is empty so its setting the var to empty, that's why it's displaying that way, but why is this passing twice:

if(this.in_mytag) ??

Thanks for any help.

I made a new XML file on my server and that one seemed to work. I killed all of the white space in my own example.xml and that fixed it. Any way to remove white space in java to eliminate this issue?

Thanks

would it include images in the parsing or not?

as i'm struggling to do this.

I've tried this tutorial to parse some info out of this RSS feed but i don't get anything in return.
This is what i've modified only

First of all: thanks a lot for everything in this topic. I've only been developing Android for one week, but have learned so much from forums and topics like this.

I've read every page of this topic and I notice that a lot of people have the same problem that I'm facing, but the solution is not exactly given. I would like to ask one of you, to post a working application with the solution to the following problem (I've simplified it for easier understanding).

XML:

Code: Select all

<friends>
<person>
<name>Jack</name>
<phone>111-111-111</phone>
</person>
<person>
<name>John</name>
<phone>222-222-222</phone>
</person>
</friends>


Now, using the code in this topic, we will get John's name and John's number. Because at every person, the previous data is overwritten. We will always get the last person in the list.
I know that we need to use an array to store all the persons in the list. I've tried to get that to work, but it just doesn't. I can't seem to get the array available in the main .java source.

Can someone please show us how to store all the persons in an array and output every person using something like a for-loop? Just to show that the names and numbers are in the array.

Output should be something like:

Code: Select all

John
111-111-111
Jack
222-222-222

Thank you so much!

This will cause an OOME if you parse larger XML files. Heap space is never freed.

Large XML Files will always end up with an OOME.. so whats the point?
Its an example of a way to deal with what Buts wanted and keep the
parsed data available.

If you have a version thats running better with large files feel free to post.

Hi plusminus,


How do we replace the contents of an xml file and saving it? It will be very helpful while editing xml files.



Thanks in advance

It's not the XML parsing that causes memory issues, it's the Vector<Friends> that will cause problems. You can verify this by removing the Vector and parsing a large XML-file a couple of times. Memory will be freed after endDocument is called.

If you have to parse large XML files, or parse several XML files, or if parsing XML is a core part of your application (eg. a newsreader) my suggestion would be to store the objects in a database and retrieve them when needed.

This is not an Android problem, but more a design 'issue' in SAX. You will encounter it sooner in Android applications as the application only has 16/24Mb of heap. SAX wasn't build to store the complete XML-file, but gives you the opportunity to 'do something' after every endElement (like persisting it in a database).
