Want to Update the existing listView in fragment by clicking menuitems
0
I am creating an app for finding nearby blood donors. In this app I am using three fragments for swipe navigation. Inn one fragment, the available donor list is shown, but I want to change the list from a menu list by on a clicking particular blood group The 1st list is but when I click the items it shows nothing.
Java code:
public class DonorsFragment extends Fragment {
SwipeMenuListView listView;
FirebaseListAdapter adapter;
TextView fullName,bloodGroup,gender,age,address;
Query query;
View rootView;
FirebaseListOptions<DonorAdapterClass> options;
public DonorsFragment() {
// Required empty public constructor
}
@Override
public void onCreate(@Nullable Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setHasOptionsMenu(true);
}
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
rootView =inflater.inflate(R.layout.fragment_donors, container, false);
listView = rootView.findViewById(R.id.listview);
Toast.makeText(getActivity(),"oncreateview",Toast.LENGTH_SHORT).show();
query =FirebaseDatabase.getInstance().getReference().child("Users");
setQuery(query);
SwipeMenuCreator creator = new SwipeMenuCreator() {
@Override
public void create(SwipeMenu menu) {
// create "delete" item
SwipeMenuItem deleteItem = new SwipeMenuItem(getActivity());
// set item background
deleteItem.setBackground(new ColorDrawable(Color.rgb(0xF9,
0x3F, 0x25)));
// set item width
deleteItem.setWidth(170);
// set a icon
deleteItem.setIcon(R.drawable.ic_phone);
// add to menu
menu.addMenuItem(deleteItem);
}
};
listView.setMenuCreator(creator);
listView.setOnMenuItemClickListener(new SwipeMenuListView.OnMenuItemClickListener() {
@Override
public boolean onMenuItemClick(int position, SwipeMenu menu, int index) {
switch (index) {
case 0:
// open
Toast.makeText(getActivity(),"Item Clicked",Toast.LENGTH_SHORT).show();
break;
}
// false : close the menu; true : not close the menu
return false;
}
});
// Inflate the layout for this fragment
return rootView;
}
@Override
public void onStart() {
super.onStart();
adapter.startListening();
}
@Override
public void onStop() {
super.onStop();
adapter.stopListening();
}
@Override
public void onCreateOptionsMenu(Menu menu, MenuInflater inflater) {
super.onCreateOptionsMenu(menu, inflater);
inflater.inflate(R.menu.blood_group_menu,menu);
}
@Override
public boolean onOptionsItemSelected(MenuItem item) {
switch (item.getItemId()){
case R.id.a_pos: {

.build();
adapter = new FirebaseListAdapter(options) {
@Override

if(donors.getIsDonor().toString().equals("yes")){

bloodGroup = v.findViewById(R.id.bloodGroup_list);
gender = v.findViewById(R.id.gender_lis);
address = v.findViewById(R.id.address_list);
age = v.findViewById(R.id.age_list);
fullName.setText(donors.getFullName().toString());
bloodGroup.setText(donors.getBloodGroup().toString());
gender.setText(donors.getGender().toString());
address.setText(donors.getAddress().toString());
age.setText(donors.getAge().toString());
}
}
};
listView.setAdapter(adapter);
}
}
all firebase query and adapter is set in setQuery() method..when it is called from onCreateView() it is working...but when it is called from switch case in onOptionsItemSelected it shows nothing and previous list view also hides
Thanks in Advance :)

This is my first answer in centuries so please bear with me. This is not an answer but just pointer to the path towards solution.
Put a break-point at the following points
- onOptionsItemSelected
- case R.id.a_pos
- setQuery()
- setQuery::listView inittialization statement
- setQuery::populateView::donor initialization statement
Run the app. Attach the process with debugger. Now when you click "A+" from options, does it get a response from the server or does it throw an exception?

This is my first answer in centuries so please bear with me. This is not an answer but just pointer to the path towards solution.
Put a break-point at the following points
- onOptionsItemSelected
- case R.id.a_pos
- setQuery()
- setQuery::listView inittialization statement
- setQuery::populateView::donor initialization statement
Run the app. Attach the process with debugger. Now when you click "A+" from options, does it get a response from the server or does it throw an exception?
