Hi,
In class 1 I have a hashmap which I send to my
CustomAdapter.
map.put("year", "Apple");
map.put("make", "Mango");
map.put("model", "Grape");
map.put("style", "Orange");
map.put("series", "Peach");
Log.d(TAG, "HELLO WORLD " + map.entrySet());
//link to my adapter
setListAdapter(new MyCustomAdapter(DynamicLists.this,
R.layout.row, map));
but in class 2 my MyCustomAdapter getView function is not getting
called, can you help understand why ?
thanks
