Question

Hi I want to pass an Arraylist from one activity to another. I use putStringArrayListExtra(), but there shows an error : "The method putStringArrayListExtra(String,ArrayList is undefined for the type bundle." Is there any other method available for passing ArrayList?

String test[]=new String[3]; 
ArrayList<String[]> al=new ArrayList<String[]>();  
int x,y;
test[0]="1";  
test[1]="2";  
test[2]="3";  
al.add(test);  

test = new String[3]; 
test[0]="4";  
test[1]="5";  
test[2]="6";  
al.add(test);  

Bundle list_bundle=new Bundle(); 
list_bundle.putStringArrayListExtra("lists",al); 
Intent list_intent= new Intent(v.getContext(), view_all_selected.class); 
list_intent.putExtras(list_bundle); 
startActivityForResult(list_intent, 2); 

Answer 1

try below one to pass 1-D array to Arraylist in extras

ArrayList<String> al = new ArrayList<String>();
String arr[] = {"Zero", "One", "Two"}; 
//Convert string array to a collection 
Collection l = Arrays.asList(arr);
al.addAll(l); 
i.putStringArrayListExtra("ar", al);
