i have small issues in event handling , i have List view custom adapter data , each row having date , title , price . when i click on row i need to display details page but when i long press on price , date or title i need to sort the list view. i need to use gesture for on Long Press. please refer below code what i have tried.
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>() {
@Override
public int compare(EventUtil obje1,
EventUtil obje2) {
return obje1
.getEvent_Title()
.compareTo(
obje2.getEvent_Title());
}
});
notifyDataSetChanged();
//}
};
}.onLongPress(event);
return true;
}
});
// event location sorting
eventDescView.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>() {
@Override
public int compare(EventUtil event1,
EventUtil event2) {
return event1
.getEvent_location()
.compareTo(
event2.getEvent_location());
}
});
notifyDataSetChanged();
//}
};
}.onLongPress(event);
return true;
}
});
// event price sorting
eventDateView.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>() {
@Override
public int compare(EventUtil event1,
EventUtil event2) {
return event1
.getEvent_Price()
.compareTo(
event2.getEvent_Price());
}
});
notifyDataSetChanged();
//}
};
}.onLongPress(event);
return true;
}
});
// event date sorting
ImageView dateImageView = (ImageView) mView
.findViewById(R.id.list_view_event_date);
dateImageView.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>() {
@Override
public int compare(EventUtil event1,
EventUtil event2) {
return event2
.getEvent_Date()
.compareTo(
event1.getEvent_Date());
}
});
notifyDataSetChanged();
//}
};
}.onLongPress(event);
return true;
}
});
MyGestureDetector Class
public class MyGestureDetector extends SimpleOnGestureListener {
@Override
public void onLongPress(MotionEvent e) {
super.onLongPress(e);
}
}
Help Me.. Thanks
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.
