I am Facing a problem in setting a ListView in android . Everything works ok but it is not setting the way i want it to set . here are the images whats happening
when i add the data it displays fine and inserts the data accurately but when i go back and then again starts the activity , it retrieves the data and displays it in single row of listview .
1)i want to display the data each entry on different items of listview . i don't know how can i achieve it .
2)when i start the activity it should display all database entries and when i add the new item it should append with the previous list . but what actually happening is when there are already 3 records showing and i add one more record it displays the single record last added . previously added records are gone . i don't know why they are not displaying .
here is my code :
public class noticall extends ListActivity {
CustomDateTimePicker custom;
TextView tv,tv1;
EditText ed;
String store;
static String Names;
public static final int PICK_CONTACT = 1;
String [] adi ;
String [] adi1 ;
String [] adi2 ;
String [] adi3 ;
