How to iterate Arraylist<HashMap<String,String>>?

I have an ArrayList object like this:

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

How to iterate through the list? I want to display the value in a TextView which comes from the data of ArrayList object.

Simplest is to iterate over all the HashMaps in the ArrayList and then iterate over all the keys in the Map:

TextView view = (TextView) view.findViewById(R.id.view);

for (HashMap<String, String> map : data)
     for (Entry<String, String> entry : map.entrySet())
         view.append(entry.getKey() + " => " + entry.getValue());
