Answer 1

Create the SQLite Database table by executing the query to create a new table according to your constraints.

db.execSQL("CREATE TABLE "+employeeTable+" 
    ("+colID+" INTEGER PRIMARY KEY AUTOINCREMENT, "+
        colName+" TEXT, "+colAge+" Integer, "+colDept+" 
    INTEGER NOT NULL ,FOREIGN KEY ("+colDept+") REFERENCES 
    "+deptTable+" ("+colDeptID+"));");

Use ContentValues to update/insert data in the table.

SQLiteDatabase db=this.getWritableDatabase();
ContentValues cv=new ContentValues();
   cv.put(colDeptID, 1);
   cv.put(colDeptName, "Sales");
   db.insert(deptTable, colDeptID, cv);

   cv.put(colDeptID, 2);
   cv.put(colDeptName, "IT");
   db.insert(deptTable, colDeptID, cv);
   db.close();

and Cursor to retrieve data from the table.

Cursor getAllDepts()
  {
   SQLiteDatabase db=this.getReadableDatabase();
   Cursor cur=db.rawQuery("SELECT "+colDeptID+" as _id, 
    "+colDeptName+" from "+deptTable,new String [] {});

   return cur;
  }

Disclaimer : This answer is only to help you understand how to work with SQLite (as you say that you haven’t been able to come across any convincing ideas). You would need to write your own code to handle the logic of retrieving the events according to the date selected in the DatePicker, but I think that should not be much of a problem.
