Yet now i am getting the all data from the FireBase at one time.What i want to do that getting data in LIMITS like 15 records at a tim

Answer 1

restructure your database, set a new child id which is incremental like 0,1,2,3... etc

"chats": {
"-KZLKDF": {
  "id": 0,
  "message": "Hi",
  "name":"username"
},

then make a method for query

public void loadFromFirebase(int startValue,int endValue){

mChatRef.orderByChild(id).startAt(startValue).endAt(endValue).addListenerForSingleValueEvent(this);
}

make sure you have implemented addListenerForSingleValueEvent then do adapter related task. Initially call from onCreate method:

loadFromFirebase(0,10);

NB: loading new content in the list you have to be aware with adapter.
