空指針異常 - 安卓

Question

我收到一個列表從AWS DynamoDB低於特定使用掃描代碼：

List<DBMarkers> markers= new ArrayList<DBMarkers>(); 

markers = mapper.scan(DBMarkers.class, scanExpression); 
Log.d("DynDBS::markers recvd :", String.valueOf(markers.size())); //This shows size as 2 

for(DBMarkers temp : markers) { 
    temp.getname(); //method in my class - get nullpointer here 
} 

有誰知道如何着手？

Answer 1

與此

for(int i=0; i<markers.size(); i++) { 
DBMarkers temp = markers[i] 
temp.getname(); //method in my class - get nullpointer here 
}
