I would like use parsing XML (the file is on the Net) to get a title in a listView and on the click call an Activity with a part of my parsing.

I would like use parsing XML (the file is on the Net) to get a title in a listView and on the click call an Activity with a part of my parsing.

Example : My xml contents :

<title>Video 1</title><link>http://video.mp4</link>
<title>Video 2</title><link>http://video2.mp4</link>

ListView sh开发者_如何学运维ow : Video 1, Video 2

And on the click it launch the link (via an intent.putExtra).

How can I do to make this ?

Thank you very much


  1. Parse your XML into a map. Map<VideoName,VideoLink>
  2. Set the list text to the keys of your map.
  3. Create a onClick listener for your list in which you should get the key that was clicked and retrieve the value and start the intent.

Here is how you do it:

final HashMap<String, String> xmlMap = xmlToMap();
final String[] titleArray=(String[]) xmlMap.keySet().toArray();
ListView lv=new ListView(this);
lv.setAdapter(new ArrayAdapter<String>(this, android.R.layout.simple_list_item_1 ,titleArray));
lv.setOnItemClickListener(new AdapterView.OnItemClickListener()
{
    @Override
    public void onItemClick(AdapterView<?> parent, View view, int pos, long id)
    {
        String videoTitle=titleArray[pos];
        String videoLink=xmlMap.get(titleArray[pos]);
    }
});


HashMap<String, String> xmlToMap()
{
    HashMap<String, String> xmlMap = new HashMap<String, String>();
    // Parse the xml document you have.
    // In the xml parsing loop 
        // Every 'title' tag you read and corresponding 'link' 
        //tag you read you insert an element into map
            String title=""; // Every 'title' tag you read
            String link=""; // Corresponding 'link' tag 
            xmlMap.put(title, link);
    // Loop ends
    return xmlMap;
}
