Storing data into String array and pass it to AsyncTask

Question

I am getting all of my contacts details from contactconstract table, and Want to store all my contact data to String array then I would like to pass it to AsyncTask for doing some background task,Currently I am passing single contacts detail to AsyncTask,that would made my code crash because one by one asynctask is being called for each contact detail, I would like to store all my contact detail into array an then I pass this array to AsyncTASK so only one time AsyncTask would call so Please help me in this regard,

Given below is my part of the code:

ContentResolver cr = getContentResolver();
        SavingContacts savingcontacts=new SavingContacts();
        Cursor = getContentResolver().query(
                 ContactsContract.CommonDataKinds.Phone.CONTENT_URI, null,
                 null, null,
                 ContactsContract.Contacts.DISPLAY_NAME + " ASC");
        Log.d("database1" ,"17");
       if (Cursor.getCount() > 0)  {
             while (Cursor.moveToNext()) {

                  phone = Cursor.getString(Cursor.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER));
                 if (!TextUtils.isEmpty(phone)) {

                     Log.d("Your Location4", "ok4:");
                          name = Cursor.getString(Cursor.getColumnIndex(ContactsContract.CommonDataKinds.Phone.DISPLAY_NAME));
                          id = Cursor.getString(Cursor.getColumnIndex(ContactsContract.CommonDataKinds.Phone.CONTACT_ID));
                         // photouri=Cursor.getString(Cursor.getColumnIndex(ContactsContract.CommonDataKinds.Photo.PHOTO));
                          email=Cursor.getString(Cursor.getColumnIndex(ContactsContract.CommonDataKinds.Email.TYPE));
                         System.out.println("contactId="+ id+ ", name=" + name + ", phoneNumber=" + phone+"Email="+email);

                 }
                 savingcontacts.savingcontact(id, name, phone, email);
             }


                }
       Cursor.close();

You mean to say I have to make 4 array list for id, name,phone,emial?I created just One array list like ArrayList<String> passing = new ArrayList<String>(); and then use passing.add(id),passing.add(name)....like that, isn't a right approach? — Shazar

if you have 4 parameter then create one class, and send one list of that class to asyncTask class — Shayan Pourvatan

can you please give me some idea or post a answer it would be highly appreciated thanks — Shazar

you need create one class for your purpose like following:

public class Contact()
{
   private String _name , _phoneNum , _email , _id;

   public Contact(String id , String name , String phoneNum , String emailAdd)
   {
      _name = name;
      _phoneNum = phoneNum;
      _id = id;
      _email = emailAdd;
   }

   public void SetName(String name)
   {
        _name = name;
   }

   public String GetName()
   {
        return _name;
   }

 // other getter and setter
}

and for passing to your AsyncTask use:

    ArrayList<Contact> contacts = new ArrayList<Contact>()

   // add this two line and do this for all your obj

   Contact contact = new Contact(id , name , phoneNumber , emailAddress);
   contacts.add(contact);

  // after putting all data to contacts do following code

   TestAsyncTask task= new TestAsyncTask();
   task.execute(contacts);

and AsyncTask class:

class TestAsyncTask extends AsyncTask<ArrayList<Contact>, Void, Void>{

         @Override
         protected Void doInBackground(ArrayList<Contact>... params) {
                 // TODO Auto-generated method stub

                 ArrayList<Contact> contactArray = params[0];             

                 return null;
           }
        }

While declaring the AsyncTask in your class , declare it as follow :

  class TestAsyncTask extends AsyncTask<String[], Void, Void>{

                @Override
                protected Void doInBackground(String[]... params) {
                    // TODO Auto-generated method stub

                                 String[] strArray = params[0];             

                    return null;
                }

            }

The first parameter for the accepts the parameter you want to pass to the Asynctask created by you.

Also, call it as :

new TestAsyncTask().execute(myStringArray);

Create an array list like

 ArrayList<SavingContact> contactList = new ArrayList<SavingContact>();

and when you are adding into model object add that object tnto array list like

savingcontacts.savingcontact(id, name, phone, email);
contactList.add(savingcontacts);

and then pass this arraylist in constructor of your asyntask class.

Create a object "Contact" and fillt it with set and get method for ID, NAME, PHONE, and EMAIL.

public class Contact()
{
   private String _name;

   public void setName(String name)
   {
        _name = name;
   }

   public String getName()
   {
        return _name;
   }

   [...]
}

Store all your contacts in a List:

List<Contact> contacts = new ArrayList<Contact>()

Send your list to your AsyncTask

Best You Can use like this

class TestAsyncTask extends AsyncTask<ArrayList<String>, Void, Void>{

            @Override
            protected Void doInBackground(ArrayList<String>... params) {
                // TODO Auto-generated method stub

                             for(int i =0 ; i<params.size();i++)
                            {
                               String Str = params.get(i);
                            }        

                return null;
            }

        }

you can use like that,its easy way to store values to Array and also get values
