Question

I have a custom listadapter with an image and text at each level. I want to get the text of the selected level.

 public View updateView(View view, TreeNodeInfo<Long> treeNodeInfo) {
            final LinearLayout viewLayout = (LinearLayout) view; 
            final TextView descriptionView = (TextView) viewLayout.findViewById(R.id.item);
            final ImageView img = (ImageView)viewLayout.findViewById(R.id.image);




return viewLayout;  }

In my activity class i have a clicklistener on the list.

 customlist.setOnItemClickListener(new OnItemClickListener(){
                        @Override
                        public void onItemClick(final AdapterView<?> parent, final View view, final int position, final long id){
                             //dostuff
                        }
                    }); 

(TextView)view.findViewById(R.id.item);

returns only the text for the first item only and not any other selected item on the list.

How do i get the text of the selected item.??

Use the underlying data used to bind the text to the text view, update that data, and notify the ListView that the data changed.

For example
List<Map<String,String> data = new List<Map<String,String>>();
// a bunch of add's

adapter = new SimpleAdapter(Activity.this, data, R.layout.list_item, 
      new String{TEXT1, TEXT2, TEXT3, IMG1}, 
      new int[] {R.id.text1, R.id.text2, R.id.text3, R.id.IMG1});
// set adapter

// ...

onListItemClick(..., int position, long id){
Map<String,String> item = data.get(position);
   item.put(TEXT1, updatedText1String);
   item.put(TEXT2, updatedText2String);
   item.put(TEXT3, updatedText3String);
   listView.notifyDataSetChanged();
}
