Parse XML in Android for ListView

Parse XML in Android for ListView - android

I'm currently working on parsing xml for android listview.
I was able to parse and get a data for my listview.
But, what if I want to get a specific data from that XML. hmmm like performing
something in SQL "select * from [table] where id = 1".
Something like that...How can I do that with my XML?
Thanks

You should parse the xml file just once and create an array or list of objects from it. Once you have everything on memory you can use the array to populate your list with an ArrayAdapter. The position in the array can be used as your id. If you rather have an attribute of the object be the id instead of the position then you can just sort the array accordingly.

Correct item is not selected in Listview

I am using this Tutorial for Creating a custom listview with radio button. In this tutorial when we click the item in the list then color of item change.
This is happening when i am testing this code above 4.0 but below 4.0 it is not workin properly I am not understand why????

int loader = R.drawable.image_not_available;
String image_url = asm.thumsrc;

}
At last your Model class
public class GoModelAll {
public String description = "";
public String excert = "";
public String thumsrc = "";
public String title = "";
public int postid = 0;
public boolean isSeen = false;
}

Show us your adapter code as well and try not to change an item of list view from setOnItemClickListener instead change your data and notify adapter to refresh the view.
Set this as background to your list item :
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:state_pressed="true" android:color="#color/white" />
<item android:color="#color/black" />
</selector>

because you are getting all titles inside model_Inserts List you will need to pass this List to Custom BaseAdapter for showing in TextView as :
Change ShowAllContent() method as:
public void ShowAllContent() {
GridView gridView1 = (GridView) findViewById(R.id.grid_all);
gridView1.setAdapter(new ImageAdapter(TopActivity.this, placeList,model_Inserts));
}
and ImageAdapter constructor as :
public class ImageAdapter extends BaseAdapter {
private ArrayList<HashMap<String, String>> MyArr =
new ArrayList<HashMap<String,String>>();
List<Model_Insert> model_Inserts=null;
public ImageAdapter(Context c,
ArrayList<HashMap<String, String>> myArrayList,
List<Model_Insert> model_Inserts){
context = c;
MyArr = myArrayList;
this.model_Inserts=model_Inserts;
}
///your code here...
now use model_Inserts for getting Title to show inside getView

Use below xml code instead of your xml code, it will solve your problem and if you have any problem regarding that then tell me.

Android DOM Parser - retrieving image link from description tag

I'm using DOM Parser to parse this XML feed: http://loc.grupolusofona.pt/index.php/?format=feed
I got the Parser working fine for all tags, i'm just missing ideas to be able to retrieve the image from within the description tag.
The description tag on the feed looks like this:
<description><![CDATA[<div class="K2FeedIntroText"><p><img style="margin: 10px;"
alt="joana soares rostos" src="http://loc.grupolusofona.pt/images/stories/varios/joana%20soares%20rostos.jpg"
height="110" width="120" />Quis ser veterinária mas deixou-se seduzir pela magia
de retratar o real. Joana Soares frequenta o primeiro ano do curso de Fotografia
da Lusófona e descreve a sua paixão pelas fotos como «inexplicável».</p>
</div>]]></description>
And i wanted to retrieve the image link:
http://loc.grupolusofona.pt/images/stories/varios/joana%20soares%20rostos.jpg
My Parser :
public class XMLParser {
// constructor
public XMLParser() {

startActivity(in);
}

}
}
Any ideas ?
Thanks for your time.

Use RegEx with a simple pattern like this:
<\s*img\s*[^>]+src\s*=\s*(['"]?)(.*?)\1
Here use these functions:
public static String getMatch(String patternString, String text, int groupIndex){
Pattern pattern = Pattern.compile(patternString, Pattern.CASE_INSENSITIVE | Pattern.DOTALL );
return RegEx.getMatch(pattern, text, groupIndex);
}
public static String getMatch(Pattern pattern, String text, int groupIndex){
if(text!=null){
Matcher matcher = pattern.matcher(text);
String match = null;
while(matcher.find()){
match = matcher.group(groupIndex);
break;
}
return match;
}else{
return null;
}
}
Then you can plug in that pattern like this:
String imageSource = getMatch("<\\s*img\\s*[^>]+src\\s*=\\s*(['\"]?)(.*?)\\1", description, 2);
