Set maximum number of rows for a ListView

Question

This is a question about Android programming. I need to limit the maximum number of visible rows in my ListView.

In onCreate method I have the next code for my ListView:

listView.setAdapter(new ArrayAdapter<String>(this, android.R.layout.simple_list_item_1, arrayListOfElements));

In onPostExecute method I have the next adapter:

ArrayAdapter<String> adapter = (ArrayAdapter<String>) arrayListOfElements.getAdapter();
adapter.notifyDataSetChanged();

So I need to set a maximum number of rows for my adapter, I don't care if the ListView will be scrollable or not. Any idea?

Do this in your base adapter (mList is your list of items to show in the listview):

public int getCount() {
    if (mList != null) {
        return Math.min(mList.size(), YOU_MAX_VALUE);
    } else {
        return 0;
    }
}
