Android Firebase How to Read the Data from Current User ID?

Question

This is my code I want to read the current user id data from firebase.

DatabaseReference ref2;
ref2=db.getReference("HiringWalker").child(FirebaseAuth.getInstance().getCurrentUser().getUid());

I want to read the current user id and -Lwg_.... all the data.

Answer 1

This won't work because you need to go one level deeper, there is one more child that I unknown how you create it

ref2=db.getReference("HiringWalker").child(FirebaseAuth.getInstance().getCurrentUser().getUid());

Do this instead

ref2=db.getReference("HiringWalker").child("ciu12tcL4RfzmC3T6Gdp64LgiZa2").child(FirebaseAuth.getInstance().getCurrentUser().getUid());

Check where are you creating this ciu12tcL4RfzmC3T6Gdp64LgiZa2 and replace that .child("ciu12tcL4RfzmC3T6Gdp64LgiZa2") with the current implementation that generates that random number

Answer 2

Your query is correct, but the fetch data is incorrect, should be modified from

ref2.addValueEvent(new ValueEventListener() {
@Override
public void onDataChange(@NonNull DataSnapshot dataSnapshot) {

    infoList.clear();

    for (DataSnapshot infoSnapshot : dataSnapshot.getChildren())
    {
        for (DataSnapshot infomationsnap : infoSnapshot.getChildren())
        {
            ReWalker rewalker = infomationsnap.getValue(ReWalker.class)
            infoList.add(rewalker);
        }
    }

});

to

ref2.addValueEvent(new ValueEventListener() {
@Override
public void onDataChange(@NonNull DataSnapshot dataSnapshot) {

    infoList.clear();

    for (DataSnapshot infoSnapshot : dataSnapshot.getChildren())
    {
        ReWalker rewalker = infoSnapshot.getValue(ReWalker.class)
        infoList.add(rewalker);
    }

});
