Question

I’m trying to sort the list items, I’m using custom listview. In this i have stored the items in the string array. but while listing the items, the listview is showing empty items instead of sorted items. But while debugging the string arrays are stored in sorted format. How to solve it?

Answer 1

I have seen the code and I got some potential problem with below statement

HashMap<String, String> sampleObjectMap = new HashMap<String, String>();

            titles[i-1]=**sampleObjectMap.put("title", dh.val1(i-1))**;
            persons[i-1]=**sampleObjectMap.put("person", dh.pers(i-1))**;
            priorities[i-1]=**sampleObjectMap.put("priorty", setpriority(String.valueOf(dh.getpriority(i-1))))**;
            dates[i-1]=**sampleObjectMap.put("dat", getDate(Long.valueOf(dh.time(i-1)),"dd/MM/yyyy"))**;

This bold statement will return the value of any previous mapping with the specified key or null if there was no such mapping. so I am assuming there were no previous mapping has been done in this case. so please make sure you array is filled up
