Best way of showing Stream Data in Android Listview

Question

We are trying to show a table data on a listview. The data consists of 8 columns and around 50 rows. In one second period approximatelly 8 update data comes. (ie:update row2-column5 to something.) Every time a new data comes, we are updating the dedicated cells and we call datasetchanged() of the adapter and this causes some performance and scrolling problems.

My question is:
What is the best way of showing stream data in Android using standard widgets?

@dziobas:i have used BaseAdapter. – e13420xx Jul 18 '11 at 12:40 — e13420xx, Jul 18 '11 at 12:40

You could try refreshing only the items that need updating. To do so, you will need the position of the data in the listview.

private void updateData(int position)
{
    int firstItem = listView1.getFirstVisiblePosition();
    View view = listView1.getChildAt(position - firstItem);
    TextView tv = (TextView)view.findViewById(R.id.textview);
    tv.setText("Example Text");
}

I would either write my own Cursor and plug it into CursorAdapter and an AdapterView, or...just use the MatrixCursor. The MatrixCursor allows you to add new "row". Then you can call onChange() to notify the View your data has changed.
