I have a ListActivity in which i am population a dialog box for picking contact info and picking Date and Time . In order to generate a notification on that time . I have done it and all the data is showing in ListView .
so what i want to do is as user pick and sets the time for notification the listView row data should store in database (sqlite). and when user start the activity the stored data can be shown to user . so users can see their notifications plan ..
now that i have listViews implemented i don't know how to store and retrieve data in sqlite .. i have searched and tried many tutorials but nothing is working in this context .
i am sharing my code its a bit rough . but i will highlight where the data is and from there how can store it to database.
here is my notification class:
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 ;
static int incre=0;
ArrayList<String> myrows = new ArrayList<String>();
ArrayList<String> time1 = new ArrayList<String>();
ArrayList<String> name1 = new ArrayList<String>();
ArrayList<String> number1 = new ArrayList<String>();
private PendingIntent pendingIntent;
ListView listview;
String temp1 ,temp2 ;
int x=0;
OnItemClickListener listener;
String Date,Time,Name,Number;

listview = (ListView) findViewById(android.R.id.list);
listview.setDividerHeight(2);
// mySQLiteAdapter = new SQLiteAdapter(noticall.this);

finish();
}

String AM_PM) {
Calendar calendar = Calendar.getInstance();
calendar.set(year, monthNumber, date, hour24, min, 0);
long when = calendar.getTimeInMillis(); // notification time
Intent myIntent = new Intent(noticall.this, MyReceiver.class);
pendingIntent = PendingIntent.getBroadcast(noticall.this, 0, myIntent,0);
AlarmManager alarmManager = (AlarmManager)getSystemService(ALARM_SERVICE);
alarmManager.set(AlarmManager.RTC, calendar.getTimeInMillis(), pendingIntent);
Date = calendarSelected.get(Calendar.DAY_OF_MONTH) + "/" + (monthNumber+1) + "/" +year;
Time = hour12 + ":" + min + " " + AM_PM;
Log.e("Timeee", Time+"");
setlisto(Date);

// Get the URI that points to the selected contact
Uri contactUri = data.getData();
// We only need the NUMBER column, because there will be only one row in the result
String[] projection = {ContactsContract.CommonDataKinds.Phone.NUMBER, ContactsContract.CommonDataKinds.Phone.DISPLAY_NAME, ContactsContract.CommonDataKinds.Phone.CONTACT_ID};
String[] segments = contactUri.toString().split("/");
String id = segments[segments.length - 1];
// Perform the query on the contact to get the NUMBER column
// We don't need a selection or sort order (there's only one result for the given URI)
// CAUTION: The query() method should be called from a separate thread to avoid blocking
// your app's UI thread. (For simplicity of the sample, this code doesn't do that.)
// Consider using CursorLoader to perform the query.

My point is as user add list rows for notifications it should also be inserted in database and later when activity is initiated the stored notification data must displayed and later i will implement deleting it from listview and from database.
Table should contain following columns:
| ID | NAME | NUMBER | DATE | TIME |
If someone can help me with sample code or refactor this code for success. My skills in database are really weak .. it will be appreciatable. Thanks
cmon guys i really need help in this please.
