Question

I have ArrayList>. In another activity I want to access all values stored in ArrayList>.

I have tried following code:

ArrayList<HashMap<String, String>> mylist = new ArrayList<HashMap<String, String>>();

for(Hashmap<String, String> map: mylist) {
    for(Entry<String, String> mapEntry: map) {
        String key = mapEntry.getKey();
        String value = mapEntry.getValue();
    }
}

but it shows an error at for(Entry<String, String> mapEntry: map) that it only interate over Array.

Answer 1

Your code has bit different for this line,

for(Entry<String, String> mapEntry: map.entrySet())

Try this and let me know what happen,

for (HashMap<String, String> map : mylist)
     for (Entry<String, String> mapEntry : map.entrySet())
        {
        String key = mapEntry.getKey();
        String value = mapEntry.getValue();
        }
