Filter List Items By Name, ID

I am working on android application that retrieve data from the firebase and show that particular data in list Like This

Now What I have to do is search the items for the list that I have retrieved From Fire base; Apply Search Filter on the basis of Name, Usage and Id.

Here the links and question that I previously studied on Stack Overflow Link1 Link 2 Link3

All of these questions only search on the basis of single Item like name not the multiple Items.

Here is m Adapter class

public class RetreiveActivity extends AppCompatActivity
ListView mylistView;
DatabaseReference db;
SearchView sv;
List<ClassMedicine> medicineList;
@SuppressLint("WrongViewCast")
@Override
protected void onCreate(Bundle savedInstanceState)
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_retreive);
mylistView= findViewById(R.id.mylist);
sv= findViewById(R.id.etSearch);
medicineList= new ArrayList<>();
db= FirebaseDatabase.getInstance().getReference("medicines");


@Override
protected void onStart()
super.onStart();
db.addValueEventListener(new ValueEventListener()
@Override
public void onDataChange(DataSnapshot dataSnapshot)
medicineList.clear();
for (DataSnapshot medicineSnapshot:dataSnapshot.getChildren())
ClassMedicine classMedicine=medicineSnapshot.getValue(ClassMedicine.class);
medicineList.add(classMedicine);

MedicineList adapter=new MedicineList(RetreiveActivity.this,medicineList);
mylistView.setAdapter(adapter);

@Override
public void onCancelled(DatabaseError databaseError)

);




Here is my List Layout File

<LinearLayout

Here is my Model Class

public class ClassMedicine
String medicineId;
String medicineName;
String medicineUsage;
String medicineGenre;
String mediDate;
public ClassMedicine()



public ClassMedicine(String medicineId, String medicineName, String medicineUsage, String medicineGenre, String mediDate)
this.medicineId = medicineId;
this.medicineName = medicineName;
this.mediDate= mediDate;
this.medicineUsage = medicineUsage;
this.medicineGenre = medicineGenre;


public String getMedicineId()
return medicineId;


public String getMedicineName()
return medicineName;


public String getMedicineUsage()
return medicineUsage;


public String getMedicineGenre()
return medicineGenre;


public String getMediDate() return mediDate;
