Adding Long Press Listner to Listview inside a Recycler view

Adding Long Press Listner to Listview inside a Recycler view - android

I have been searching a lot of tutorials to implement an on item long press Listener on a Listview which is Inside a RecyclerView. So far I had no luck.
I want a menu to more ap after holding the List Item for some time. I am attaching my code here please help me with it.
I have added my complete code Including the MainAcyivity.
I have a tabbed view which contains 3tabs. Inside the tab view, there is a fragment which contains a Listview.
I want the List to be long pressed to bring a popup menu which has as add or delete options.

1- create your menu items (your list item to show on long click)
<menu xmlns:android="http://schemas.android.com/apk/res/android" >
<item
android:id="#+id/one"
android:title="One"/>
<item
android:id="#+id/two"
android:title="Two"/>
<item
android:id="#+id/three"
android:title="Three"/>
</menu>
2- setup listener and menu.
#Override
public void onBindViewHolder(DemoViewHolder holder, int position) {
holder.title.setText(arrayList.get(position));
holder.setOnLongClickListener(new View.OnLongClickListener() {
#Override
public boolean onLongClick(View v) {
showMenu(v);
return true;
}
});
}
// method to open a popup menu(list) upon long click in the recyclerView item
private void showMenu(View view){
PopupMenu popup = new PopupMenu(context,view );
popup.getMenuInflater()
.inflate(R.menu.popup_menu, popup.getMenu());
popup.setOnMenuItemClickListener(new PopupMenu.OnMenuItemClickListener() {
public boolean onMenuItemClick(MenuItem item) {
return true;
}
});
popup.show();
}

When you are doing setOnItemLongClickListener() in the ListView:
lv.setOnItemLongClickListener(new OnItemLongClickListener() {
#Override
public boolean onItemLongClick(AdapterView<?> arg0, View arg1,
int pos, long id) {
// Dialog/Popup will appears here
showAddDeleteDialog();
return true;
}
});
public void showAddDeleteDialog(){
AlertDialog.Builder dialog = new AlertDialog.Builder(MainActivity.this);
dialog.setCancelable(false);
dialog.setTitle("Add or Delete Dialog");
// dialog.setMessage("Are you sure you want to delete this entry?" );
dialog.setPositiveButton("Add", new DialogInterface.OnClickListener() {
#Override
public void onClick(DialogInterface dialog, int id) {
//Action for "Add".
}
})
.setNegativeButton("Delete", new DialogInterface.OnClickListener() {
#Override
public void onClick(DialogInterface dialog, int which) {
//Action for "Delete".
}
});
final AlertDialog alert = dialog.create();
alert.show();
}

i found out
change this
RecyclerView myrv = view.findViewById(R.id.recyclerview_id_badr_kurdi);
RecyclerViewAdapter mAdapter = new RecyclerViewAdapter(getContext(), lstItems);
myrv.setLayoutManager(new GridLayoutManager(getContext(), 3));
myrv.setAdapter(mAdapter);
to this
RecyclerView myrv = view.findViewById(R.id.recyclerview_id_badr_kurdi);
mAdapter = new RecyclerViewAdapter(getContext(), lstItems);
myrv.setLayoutManager(new GridLayoutManager(getContext(), 3));
myrv.setAdapter(mAdapter);
the reason is
before We call onCreate this RecyclerViewAdapter mAdapter = new RecyclerViewAdapter(getContext(), lstItems); was initialized and in last one if we make this class a new abject , it will be a new initializing value

Changing Text visibility according to tab and setting background color of tab

I have used a custom toolbar.Inside custom toolbar I do have a textView above the tabs.Now I want to set the visibility of TextView to off for the second and third tabs.This is a image of my layout
In this image when the Ongoing tabs is selected the textfield above the tab(The ongoing survey closes on.........GMT) should be visible while for rest of the tabs the textview visibility should be gone.How can I do this?
The next problem is I have set the background of whole layout to using a background image in parent layout.But I am getting default background behind tabs.What I want is to remove the default tab background color and get the background of parent.How to do this?
This is my code for my layout:

Issue is your trying to set the TextView of Fragment layout.
As per your code your TextView is in the ScreenSlidePageFragment layout.
Remove the 'TextView' setText in onPageeSelcted
Change your ScreenSlidePageFragment like this
private class ScreenSlidePageFragment extends Fragment {
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
// Inflate the layout for this fragment
View row = inflater.inflate(R.layout.activity_screen_slide, container, false);
TextView txt=(TextView) row.findViewById(R.id.txtcoba);
txt.setText("page using fragment");
return row;
}
}

}
there are two more fragments
1-AppActivity
1-AppUsage
but there is no code for them yet
I hope I have cleared everything.
mainactivity loads with pagertitlestrip---> on setting ---> click on button---> open activity list of installed app with check box.(used ListView as placeholder )
exact feature available in app lock where user is asked to select apps to lock.
Thank You

Intent intent = new Intent(getActivity(), Activity_name.class);
startActivity(intent);
