I get those errors when i run my app:
FATAL EXCEPTION: main Process: com.google.example.adinaranayaragh, PID: 26564 com.google.firebase.database.DatabaseException: Class com.google.example.adinaranayaragh.MyItem$Sellm does not define a no-argument constructor.

My project is available on Github.
Here's the firebase database structure:
{
"items": {
"it1": {
"buy": {
"buyBellow": 19023,
"date": "7.jan2016",
"stoploss": 12455,
"target1": 12548,
"target2": 12444
},
"sell": {
"date": "7jan",
"sellAbove": 22000,
"stoploss": 14522,
"target1": 21222,
"target2": 22245
},
"title": "Gold"
},
"it2": {
"buy": {
"buyBellow": 19023,
"date": "7.jan2016",
"stoploss": 12455,
"target1": 12548,
"target2": 12444
},
"sell": {
"date": "7jan",
"sellAbove": 22000,
"stoploss": 14522,
"target1": 21222,
"target2": 22245
},
"title": "GoldM"
},
"it3": {
"buy": {
"buyBellow": 19023,
"date": "7.jan2016",
"stoploss": 12455,
"target1": 12548,
"target2": 12444
},
"sell": {
"date": "7jan",
"sellAbove": 22000,
"stoploss": 14522,
"target1": 21222,
"target2": 22245
},
"title": "Silver"
},
"it4": {
"buy": {
"buyBellow": 19023,
"date": "7.jan2016",
"stoploss": 12455,
"target1": 12548,
"target2": 12444
},
"sell": {
"date": "7jan",
"sellAbove": 22000,
"stoploss": 14522,
"target1": 21222,
"target2": 22245
},
"title": "SilverM"
}
},
"news": ""
}
What I'm trying to accomplish is to make those objects (items) appear in my app in the RecyclerView, but I get the above error when I try to run it.
