Custom Adapter View

public EventAdapterView(Context context, List<EventUtil> eventList) {

        this.mContext = context;
        this.mEventUtil = eventList;
        mLayoutInflater = (LayoutInflater) context
                .getSystemService(Context.LAYOUT_INFLATER_SERVICE);
        imageLoader = new DrawableManager();

    }

    @SuppressLint("DefaultLocale")
    @SuppressWarnings("deprecation")
    @Override
    public View getView(int position, View convertView, ViewGroup parent) {
        mView = convertView;
        EventUtil eventUtil = mEventUtil.get(position);

        mView = mLayoutInflater.inflate(R.layout.row_event_adapter, null);

        TextView eventTitleView = (TextView) mView
                .findViewById(R.id.list_view_event_title);
        TextView eventDescView = (TextView) mView
                .findViewById(R.id.list_view_event_location);
        TextView eventDateView = (TextView) mView
                .findViewById(R.id.list_view_event_price);

        // final MyGestureDetector myGestureDetector= new MyGestureDetector();

        // new ImageFeach().execute(mEventUtil.getEvent_Image_Url());

        eventTitleView.setText(eventUtil.getEvent_Title());

        // event title sorting

        eventTitleView.setOnTouchListener(new OnTouchListener() {

            @Override
            public boolean onTouch(View v, MotionEvent event) {

                new MyGestureDetector() {

                    public void onLongPress(MotionEvent event1) {

                        //if (event1.getAction() == MotionEvent.ACTION_DOWN) {
                            Collections.sort(mEventUtil,
                                    new Comparator<EventUtil>() {

                                                            obje2.getEvent_Title());

                }.onLongPress(event);


                return true;
            }
        });

MyGestureDetector Class

public class MyGestureDetector extends SimpleOnGestureListener {

    @Override
    public void onLongPress(MotionEvent e) {

        super.onLongPress(e);
    }



}

Help Me.. Thanks

Is there a reason why you're not using the `ListView` method for long press? `onItemLongClickListener` — the-ginger-geek, Nov 18 '13 at 08:12
@Neil I think user wants to implement `onItemLongClickListener` on every element of `ListView`. — Chintan Soni, Nov 18 '13 at 08:46
Yeah but that is what the onItemLongClickListener is for. Look at @Dhaval's answer — the-ginger-geek, Nov 18 '13 at 08:57
Since the question is asked only about LongClick on Row only, my answer is correct. Your answer @shree202, is however right if we want elements of row to have such a listener. Cheerio. — Dhaval, Nov 18 '13 at 09:22

I think, there's no need to use SimpleOnGestureListener.

In your Custom Adapter View:

First,

eventTitleView.setFocusable(false); 
eventTitleView.setFocusableInTouchMode(false);
eventTitleView.setLongClickable(true);

eventDescView.setFocusable(false); 
eventDescView.setFocusableInTouchMode(false);
eventDescView.setLongClickable(true);

eventDateView.setFocusable(false); 
eventDateView.setFocusableInTouchMode(false);
eventDateView.setLongClickable(true);

Then, just set setOnLongClickListener (View.OnLongClickListener l) on eventTitleView, eventDescView and eventDateView as,

eventTitleView.setOnItemLongClickListener(new OnItemLongClickListener() {
        public boolean onItemLongClick(AdapterView<?> parent, View view, int position, long id) {
            //do your sorting stuff here
        }
    });

eventDescView.setOnItemLongClickListener(new OnItemLongClickListener() {
        public boolean onItemLongClick(AdapterView<?> parent, View view, int position, long id) {
            //do your sorting stuff here
        }
    });

eventDateView.setOnItemLongClickListener(new OnItemLongClickListener() {
        public boolean onItemLongClick(AdapterView<?> parent, View view, int position, long id) {
            //do your sorting stuff here
        }
    });

Hope this helps you.

Why do you need to override onlongpress?

You know this function is available by default right?

just put the price , date or title on the same Layout and give each one OnLongPressListener with the action you want..:

 ListView.setOnItemLongClickListener(new OnItemLongClickListener() {

            @Override
            public boolean onItemLongClick(AdapterView<?> arg0, View arg1,
                    int arg2, long arg3) {
                // YOUR SORTING CODE HERE

                return false;
            }
        });

but i need to handle onItemClick Listener and then i need to perfrom individual view OnLong Press like price longPress , date Long Press then i need to perform sorting – Nov 18 '13 at 08:58
According to your question, you need to sort the list on LongClick. Then this is where you put your sorting code. If you apply onCLickListener, then how on earth would you stay on ListView Activity to perform LongClick if you are Lauching another details activity? – Dhaval Nov 18 '13 at 09:12

I have done this thro onLongClickListener. It's easy using this interface . You need to do

Class YourClass implements onLongClickListener{

 public boolean onLongClick(View arg0){                                 

 // Event generated when user have long pressed the screen

  return false; // If you do not want the event to keep occuring again and again

}
