显示详细信息 firebase 数据来自 listview onitemclick Android Studio

Question

The problem I am facing is that I cannot display the detail of the ListView on which I clicked, any suggestion to display the detail of the Firebase data, I'm done for itemOnClick and change to another activity, but the problem is that it shows only the text of ListView and not the detail, thank you

LISTVIEW JAVA CLASS

databaseReference.addChildEventListener(new ChildEventListener() {
    @Override
    public void onChildAdded(@NonNull DataSnapshot dataSnapshot, @Nullable String s) {
        final String value = dataSnapshot.getValue(Sample.class).toString();
        arrayList.add(0,value);
        listcase.setOnItemClickListener(new AdapterView.OnItemClickListener() {
            @Override
            public void onItemClick(AdapterView<?> adapterView, View view, int i, long l) {
                Intent intent = new Intent(getApplicationContext(), Report.class);
                //String sample = String.valueOf(arrayList.get(i));//arrayAdapter.getItem(i);
                intent.putExtra("sample", String.valueOf(arrayList.get(i)));
                startActivity(intent);
                overridePendingTransition(R.anim.slide_right_entering, R.anim.slide_right_exiting);
                finish();
            }
        });
    }
});

CONSTRUCTOR

public Sample() {
}

public String getName() {
    return Name;
}

public void setName(String name) {
    Name = name;
}

public String getPhone() {
    return Phone;
}

public void setPhone(String phone) {
    Phone = phone;
}

public String getDate() {
    return Date;
}

public void setDate(String date) {
    Date = date;
}

public String getSymthom() {
    return symthom;
}

public void setSymthom(String symthom) {
    this.symthom = symthom;
}

public String getAddress() {
    return address;
}

public void setAddress(String address) {
    this.address = address;
}

public String getPlace() {
    return place;
}

public void setPlace(String place) {
    this.place = place;
}

public String getDateDiag() {
    return DateDiag;
}

public void setDateDiag(String dateDiag) {
    DateDiag = dateDiag;
}

public String toString (){
    return "Sample Name : " + Name + "\n"+ "Status : ";
}

DETAIL JAVA CLASS

Intent intent = getIntent();
if (intent.hasExtra("sample"))
{
    textView.setText(intent.getStringExtra("sample"));
}

I have no idea how to display detail of my Firebase object to another activity, thank you for helping me

Answer 1

Your ArrayList contains an only String , not a detail object.

final String value = dataSnapshot.getValue(Sample.class).toString();

So when you get by index it returns item value. If you share the value of value JSON structure it would be good to understand better.

Answer 2

  databaseReference.addValueEventListener(new ValueEventListener() {
            @Override
            public void onDataChange(@NonNull DataSnapshot dataSnapshot) {

                for (DataSnapshot snapshot : dataSnapshot){
                    Log.d("data", "onDataChange: "+ dataSnapshot);
                    Sample Sample = snapshot.getValue(Sample.class);
                    sampleList.add(Sample);
                }

            }

            @Override
            public void onCancelled(@NonNull DatabaseError databaseError) {

            }
        });
