Hi All,
I could trouble shoot my issue. I could insert a new record and delete
an existing one..But while editing and updating i m getting rowId as
0. it simply displays 0 for all records...
i feel we are setting the rowId to intent in this method..
protected void onListItemClick(ListView l, View v, int position, long
_id)
protected void onListItemClick(ListView l, View v, int position, long
_id){
super.onListItemClick(l, v, position, _id);
Cursor c = mCursor;
Log.d(TAG, "Position in the List "+position);
Log.d(TAG, "Cursor-----"+c);
c.moveToPosition(position);
Log.d(TAG, "Row Id for the selected Record"+c.getLong(0));
Intent i = new Intent(this,EmployeeEdit.class);
i.putExtra(EmployeeDAO.KEY_ROW_ID,_id);
i.putExtra(EmployeeDAO.EMP_NAME, c.getString(
c.getColumnIndexOrThrow(EmployeeDAO.EMP_NAME)));
i.putExtra(EmployeeDAO.EMP_AGE, c.getInt(
c.getColumnIndexOrThrow(EmployeeDAO.EMP_AGE)));
i.putExtra(EmployeeDAO.EMP_QUALIFICATION, c.getString(
c.getColumnIndexOrThrow(EmployeeDAO.EMP_QUALIFICATION)));
i.putExtra(EmployeeDAO.EMP_DEPT, c.getString(
c.getColumnIndexOrThrow(EmployeeDAO.EMP_DEPT)));
startActivityForResult(i, ACTIVITY_EDIT);
}
protected void onActivityResult(int requestCode, int resultCode,
Intent intent){
super.onActivityResult(requestCode, resultCode, intent);
Bundle extras = intent.getExtras();
switch(requestCode){
case ACTIVITY_CREATE:
String employeeName = extras.getString(EmployeeDAO.EMP_NAME);
int employeeAge =
Integer.parseInt(extras.getString(EmployeeDAO.EMP_AGE));
String employeeQualification =
extras.getString(EmployeeDAO.EMP_QUALIFICATION);
String employeeDept = extras.getString(EmployeeDAO.EMP_DEPT);
employee.insertEmployeeInformation(employeeName, employeeAge,
employeeQualification, employeeDept);
fillData();
break;
case ACTIVITY_EDIT:
Long rowId = extras.getLong(EmployeeDAO.KEY_ROW_ID);
Log.d(TAG, "RowId in Activity Edit"+rowId);
if(rowId != null){
Log.d(TAG, "RowId While Updating the record "+rowId);
String updateEmployeeName =
extras.getString(EmployeeDAO.EMP_NAME);
int updateEmployeeAge =
Integer.parseInt(extras.getString(EmployeeDAO.EMP_AGE));
String updateEmployeeQualification =
extras.getString(EmployeeDAO.EMP_QUALIFICATION);
String updateEmployeeDept =
extras.getString(EmployeeDAO.EMP_DEPT);
employee.updateEmployeeInformation(rowId,
updateEmployeeName,
updateEmployeeAge,
updateEmployeeQualification,
updateEmployeeDept);
fillData();
break;
}
}
we would be taking this value in onActivityResult() method and calling
DAO layer from there.....
i have debugged this, but rowId always remains at 0.... can anybody
find where the Problem is??
All classes are present in first Post...
Thanks in Advance
Thanks
