Fragment listview last value is not disappear

I have listview All the values are delete and update properly but only the last value is not delete in the listview.
Added a full fragment code. Take a look
For example
If I have three values in the listview If I delete 1 and 2 its removing and listview refresh properly but the last one is not refreshed in the listview
private SwipeMenuListView mylistview;
String userid;

}

you have to tell your ListView that something changed in it's former List by calling notifyDataSetChanged() method of your adapter
Also you should not create a new instance of ArrayList, but only clear the old instance. Don't forget to check for null before clearing.

try calling the adapter again with a null like.
setListAdapter()

How to replace the baseadapter value and how to stop the pagination loading in android filter screen?

I have worked with the concept of filter that have to filter the job from job list based on skills and some list or there.

By using this image if i filter the job based on the designed UI detail. That should replace into the DashboadFragment list The result should display into the DashBoard Fragment. How can I add pagination on Filter screen the same which have in DashBoardFragment.

scoreView.setText(String.valueOf(childrenArrayList.get(position).getIdEnfant()));
scoreView.setBackgroundResource(R.drawable.circular_textview);
// 5. retrn rowView
return rowChildView;
}
}
Whene i click to the row of listview i get the "id" but how i can pass it to the popupMenu.
The solution: it just add settag(position) to imageview in getview, then :
public void showMenu(View v) {
PopupMenu popup = new PopupMenu(this, v);
popup.setOnMenuItemClickListener(this);
popup.inflate(R.menu.poupup_menu);
popup.show();
listView.performItemClick(v, (Integer) v.getTag(),listView.getItemIdAtPosition((Integer) v.getTag()));
}

You can use interface to communicate between them
In your adapter class, initialize
private OnItemSelectedListener mListener;
and add these methods
public void setOnItemClickLister(OnItemSelectedListener mListener) {
this.mListener = mListener;
}
//Creating an interface
public interface OnItemSelectedListener {
public void onItemSelected(String s);
}
in onClick function in adapter
use this
mListener.onItemSelected(id);
//id is your string
you can call it in MainActivity,
adapter.setOnItemClickLister(new OnItemSelectedListener() {
#Override
public void onItemSelected(String s) {
//you will get the string here, you can pass it as an argument in popup menu
}
});

On the adapter Side:
view.findViewById(R.id.menu_btn).setTag(id);
On the ListActivity Side:
public void showPopUp(View v){
currentId = v.getTag().toString();
PopupMenu popupMenu=new PopupMenu(this,v);
popupMenu.setOnMenuItemClickListener(ListActivity.this);
MenuInflater inflater=popupMenu.getMenuInflater();
inflater.inflate(R.menu.my_pop_up,popupMenu.getMenu());
popupMenu.show();
}
On XML side:
<ImageButton android:id="#+id/menu_btn"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:background="#drawable/ic_overflow"
android:layout_marginStart="10dp"
android:layout_marginEnd="20dp"
android:layout_alignParentEnd="true"
android:layout_centerVertical="true"
android:onClick="showPopUp"/>
Note: onClick="showPopUp" is very critical here.
This should be helpful. Thank you.

How to restore fragment state onTouchEvent

I have a fragment (ItemFragment) with a bunch of EditText, a spinner and datepicker. The user input will be saved in SQL database. The user input then displayed in a list fragment (ListFragment) using RecyclerView. When a user click on the item in the list, it will go to ItemFragment and restore the user input. I added onSaveInstanceState in ItemFragment. I'm pretty new to Android so please bear with me. So how do I restore ItemFragment state during RecylerView's onTouchEvent?
ItemFragment.java (not sure if this is the correct way to do this?)
#Override
public void onSaveInstanceState(Bundle outState){
super.onSaveInstanceState(outState);
outState.putString("title", title);
outState.putString("quantity", quantity);
outState.putString("unit", unit);
outState.putString("date", date);
outState.putString("note", Note);
}
ListFragment.java
mRecyclerView.addOnItemTouchListener(new RecyclerView.OnItemTouchListener() {
#Override
public boolean onInterceptTouchEvent(RecyclerView recyclerView, MotionEvent motionEvent) {
View child = recyclerView.findChildViewUnder(motionEvent.getX(), motionEvent.getY());
if (child != null && mGestureDetector.onTouchEvent(motionEvent)) {
int position = recyclerView.getChildLayoutPosition(child);
Item selectedItem = mItems.get(position);
//How do I restore ItemFragment here???
return true;
}
return false;
}
Edited added Item.java and full code of ItemFragment.java
Item.java
public class Item {
private Long id;
private String title;
private String quantity;
private String unit;
private String date;
private String Note;
public String getNote() {
return Note;
}
public void setNote(String Note) {
this.Note = Note;
}
public String getDate() {
return date;
}
public void setDate(String date) {
this.date = date;
}
public String getUnit() {
return unit;
}
public void setUnit(String unit) {
this.unit = unit;
}
public Long getId() {
return id;
}
public void setId(Long id) {
this.id = id;
}
public String getTitle() {
return title;
}
public void setTitle(String title) {
this.title = title;
}

You probably need to use SharedPreferences or SQL database to save data .onSaveInstanceState is used for save state when fragment is possible to be destroyed.
Just pass id of item to ItemFragment and display data in it.

pass data from fragment inside view pager to another activity

i hope you guys can help me. it`s drivin me crazy find the solution...
i already read some question that similar with my problems, but none solved mine.
here`s the problems
1 have 2 activity...
first --> i have activity that contain a view pager which hold 3 tab fragment.
in this first activity i extends with fragmentActivity
and here the code
