new Intent with ListAdapter

I have a ListView loading project data from an XML-File

for (int i = 0; i < nlProject.getLength(); i++) {

            // Neue HashMap erstellen
            HashMap<String, String> map = new HashMap<String, String>();
            Element e = (Element) nlProject.item(i);

            // Jedes Kind-Knoten zur HashMap
            map.put(KEY_UUID, parser.getValue(e, KEY_UUID));
            map.put(KEY_NAME, parser.getValue(e, KEY_NAME));
            map.put(KEY_JOBTITLE, parser.getValue(e, KEY_JOBTITLE));
            map.put(KEY_JOBINFO, parser.getValue(e, KEY_JOBINFO));
            map.put(KEY_PROJECT_IMAGE, parser.getValue(e, KEY_PROJECT_IMAGE));


            //Hashmap zur ArrayList hinzufügen
            menuItems.add(map);
        }

        ListAdapter adapter = new SimpleAdapter(ListViewActivity.this, menuItems,
                R.layout.list_item_projects,
                new String[]{KEY_JOBTITLE, KEY_JOBINFO},
                new int[]{R.id.jobtitle, R.id.jobinfo});

        setListAdapter(adapter);

if I click on an item I want to load a new window displaying my task-data

Here is the code:

public void onItemClick(AdapterView<?> parent, View view, int position, long id) {


    //Neue Oberfläche starten
    Intent in = new Intent(ListViewActivity.this, ListMenuItemActivity.class);
    in.putExtra(KEY_TITLE,"title");
    in.putExtra(KEY_INFO,"info");
    in.putExtra(KEY_LOCATION, "location");
    startActivity(in);


    ListAdapter taskadapter = new SimpleAdapter(this, menuItems,
            R.layout.list_item_tasks,
            new String[]{KEY_TITLE, KEY_INFO, KEY_OBJECT, KEY_LOCATION},
            new int[]{R.id.title, R.id.info, R.id.object, R.id.location});

    setListAdapter(taskadapter);

The problem is that it change the ListAdapter(adapter) to taskadapter instead of creating a new activity/intent

How can i solve this problem?

You can add a String array as an extra by using putStringArrayList(String key, ArrayList<String> value) method; for example, 

ArrayList<String> stringArray = new ArrayList<String>();
stringArray.add("The String value you want");
stringArray.add("Another String value you want");

And for the Int array by using putIntArray(String key, int[] value) method also check this lilink for reference about EXTRA fields.

As replied in the comments above you have to write only the code to open the activity.

public void onItemClick(AdapterView<?> parent, View view, int position, long id) {


    //Neue Oberfläche starten
    Intent in = new Intent(ListViewActivity.this, ListMenuItemActivity.class);
    in.putExtra(KEY_TITLE,"title");
    in.putExtra(KEY_INFO,"info");
    in.putExtra(KEY_LOCATION, "location");
    startActivity(in);
});

You can then set the list adapter in new activity

ListAdapter taskadapter = new SimpleAdapter(this, menuItems,
            R.layout.list_item_tasks,
            new String[]{KEY_TITLE, KEY_INFO, KEY_OBJECT, KEY_LOCATION},
            new int[]{R.id.title, R.id.info, R.id.object, R.id.location});

    setListAdapter(taskadapter);

Hope it helps...
