How to set the ListView height

Question

I want to know how to set ListView's height through calculating the item view, someone says in this way.

ListAdapter listAdapter = listView.getAdapter();

if (listAdapter == null) {
    return;
}

int totalHeight = 0;

for (int i = 0; i < listAdapter.getCount(); i++) {
    View listItem = listAdapter.getView(i, null, listView);
    listItem.measure(0, 0);
    totalHeight += listItem.getMeasuredHeight();
}

But what if I put into the ListView for a class based on BaseAdapter?

is the data which you want to put it in the listview static ? or dynamic ? — William Kinaan, Mar 10 '13 at 14:41
dynamic！ then i will use the "adapter.notifyDataSetChanged();"to update the adapter — user1659372, Mar 10 '13 at 15:02
so in case of `dynamic`, are you using specific structure in side your adapter to save the data, something like `hashmap` , `arraylist` or you make your adapter read the data from external source such as `server connection` or `database`? — William Kinaan, Mar 10 '13 at 15:09

BaseAdapter only implement ListAdapter adapter interface, so there is no reason why your code shouldn't work with BaseAdapter. You can try this:

BaseAdapter listAdapter = (BaseAdapter)listView.getAdapter();

if (listAdapter == null) {
    return;
}

int totalHeight = 0;

for (int i = 0; i < listAdapter.getCount(); i++) {
    View listItem = listAdapter.getView(i, null, listView);
    listItem.measure(0, 0);
    totalHeight += listItem.getMeasuredHeight();
}
