I have the following code:
public void signOn(String id, String password){
usersReference.addListenerForSingleValueEvent(new ValueEventListener() {
@Override
public void onDataChange(DataSnapshot dataSnapshot) {
boolean valid = false;
for(DataSnapshot singleSnapshot : dataSnapshot.getChildren()){
String key = singleSnapshot.getKey();
if (key.equals(id)) {
singleSnapshot.getValue()//THIS LINE THIS LINE
Intent myIntent = new Intent(WelcomePage.this, MainActivity.class);
myIntent.putExtra("key", key);
WelcomePage.this.startActivity(myIntent);
}
}
}
@Override
public void onCancelled(DatabaseError databaseError) {
}
});
}
When I call singleSnapshot.getValue(), I get {password=passwordExample, username=usernameExample} as those are the keys and their values in my realtime database. How can I access the password value and the username value? Thank you.
>Solution :
One way to get it as HashMap and extract value from it, like this.
Map<String, String> map = (Map<String, String>) singleSnapshot.getValue();
String username = (String) map.get("username"); // You should pass exact key names here.
String password = (String) map.get("password");
