How can I set the gender radio button to its selected value from the database, as I did for the Edit Text ones.

Answer 1

Try This

First, u have to store gender value string to Firebase.

gender.equalsIgnoreCase will check if the value of gender equals Man (case man), if true then the radiobutton male will setChecked(true).

public void showFields(){
databaseReference = FirebaseDatabase.getInstance().getReference().child("user");
databaseReference.child(User_Login.userid).addValueEventListener(new ValueEventListener() {
    @Override
    public void onDataChange(DataSnapshot dataSnapshot){
        id1.setText(User_Login.userid);
        name1.setText(dataSnapshot.child("name").getValue().toString());
        password1.setText(dataSnapshot.child("password").getValue().toString());
        mobile1.setText(dataSnapshot.child("mobile").getValue().toString());
        city1.setText(dataSnapshot.child("city").getValue().toString());
        area1.setText(dataSnapshot.child("area").getValue().toString());
         String gender = dataSnapshot.child("gender").getValue().toString();
            if(gender.equalsIgnoreCase("Man")){
                mGenderMan.setChecked(true);
            }else if(gender.equalsIgnoreCase("Woman")){
                mGenderWoman.setChecked(true);
            }
    }
    @Override
    public void onCancelled(DatabaseError databaseError) {

    }
});}

Answer 2

Try following code :

if (list.contains(dataSnapshot.child("gender").getValue().toString()){
                            int pos = list.indexOf(dataSnapshot.child("gender").getValue().toString());

                            gender.setSelection(pos);
                        }

Where list is arraylist set to your gender spinner adapter.
