                // Get the (full, qualified) package name.
                String packag = info.activityInfo.applicationInfo.packageName;

                // Now, trim it with substring and the trim length.
                String trimmed = packag.substring(trimLength);
                maliste.add(trimmed);
            }

            monadaptateur adapter2 = new monadaptateur(this, maliste);

            list.setOnItemClickListener(new OnItemClickListener(){

                @Override
                public void onItemClick(AdapterView<?> arg0, View arg1, int arg2,
                        long arg3) {
                    Log.v("lalalala","lalala");

                }
                   });
            list.setAdapter(adapter2);
    }

Answer 1

if the ListView has focusable items then onClickListener will fire instead of the onItemClickListener . Set items can focus to false

list.setItemsCanFocus(false);

have a look at this thread . Also note there are workarounds for this. But the better choice would be to set items non focusable and use OnItemClickListener , or make them focusable and use an onClickListener on the views

Also, the onClickListener should not be set for the listview. Instead for each listview item in the getView() method

@Override
public View getView(int position, View convertView, ViewGroup parent) {
    // ...

    view.setOnClickListener(new OnClickListener() {

        @Override
        public void onClick(View v) {
            // your code
        }

    });

    return view;
}
