This is a method on DBAdapter Class
public OrgModel getOrg(String EmailId) {
db = dbHelper.getReadableDatabase();
String selectQuery = "SELECT * FROM ORG_TB WHERE EMAIL='" + EmailId + "' ";
Cursor cursor = db.rawQuery(selectQuery, null);
if (cursor != null)
cursor.moveToFirst();
OrgModel orgModel = new OrgModel();
orgModel.setFull_Name(cursor.getString(1));
orgModel.setEmail(cursor.getString(2));
orgModel.setPassword(cursor.getString(3));
orgModel.setLocation(cursor.getString(4));
orgModel.setContact(cursor.getString(5));
return orgModel;
}
And I am trying to fetch value from a fragment and code is
@Override
public void onActivityCreated(Bundle savedInstanceState) {
super.onActivityCreated(savedInstanceState);
SharedPreferences pref = getActivity().getApplicationContext().getSharedPreferences("MyPref", 0);
String Email=pref.getString("EMAIL_ID", null);
Log.d("Email is:", Email);
OrgModel mymod =dbAdapter.getOrg(Email);
String pass=mymod.getPassword().toString();
Log.d("Password is",pass);
}
And this is a OrgModel Class
public class OrgModel {
String Email;
String Password;
String Contact;
String Location;
String Full_Name;
public String getEmail() {
return Email;
}
public void setEmail(String email) {
Email = email;
}
public String getPassword() {
return Password;
}
public void setPassword(String password) {
Password = password;
}
public String getContact() {
return Contact;
}
public void setContact(String contact) {
Contact = contact;
}
public String getLocation() {
return Location;
}
public void setLocation(String location) {
Location = location;
}
public String getFull_Name() {
return Full_Name;
}
public void setFull_Name(String full_Name) {
Full_Name = full_Name;
}
}
Don't know where I did mistake .I want to print All the values in a row of that user from database into a fragment according to the email that is retrieved from a session value. Thank you in advanced.
