Hi
I am following the Android phone example from youtube.
It works , except for one small detail.
The app displays the list of contacts , but it doesnot display the
names of the contacts. It is a list of blank lines.
When I click on any blank line it dials the correct contact.
How do i display the name of the contact.
According to the youtube tutorial by Dan Morrill the following three
lines should be displaying the name. Am I missing anyhting?
String[] columns = new String[] {People.NAME};
int[] names = new int[] {R.id.row_entry};
mAdapter = new SimpleCursorAdapter(this, R.layout.main, C, columns,
names);
I have attached my code below.
Thanks in advance
mario
