I tried modifying the query in ascending order but still the output is not in alphabetical order.
The following is the MainActivity.java file:

package com.example.user.phonebook;

import android.app.ListActivity;
import android.content.ContentResolver;
import android.content.Context;
import android.content.CursorLoader;
import android.database.Cursor;
import android.net.Uri;
import android.os.Build;
import android.os.Bundle;
import android.provider.ContactsContract;
import android.util.Log;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.ArrayAdapter;
import android.widget.TextView;



import java.util.ArrayList;
import java.util.Collections;

public class MainActivity extends ListActivity {

ArrayList<contact> contacts;

@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);

contacts = new ArrayList<contact>();

Uri allContacts = ContactsContract.Contacts.CONTENT_URI;

//declare our cursor
Cursor c;

String[] projection = new String[]
{ContactsContract.Contacts._ID,
ContactsContract.Contacts.DISPLAY_NAME,
ContactsContract.Contacts.HAS_PHONE_NUMBER};


if (Build.VERSION.SDK_INT < 11) {
//---if the device ids running on OS before Honeycomb
//use the managedQuery() of the Activity class to retrieve a managed cursor
c = managedQuery(allContacts, projection, null, null, null);

} else {
//---Honeycomb and later use the cursor loader class to retrieve managed cursor---
CursorLoader cursorLoader = new CursorLoader(
this,
allContacts,
projection,
null,
null,
null);
c = cursorLoader.loadInBackground();
}

PrintContacts(c);

MyClassAdapter adapter;


//detect the android version again..
if (Build.VERSION.SDK_INT < 11) {
//---if it is before Honeycomb---

adapter = new MyClassAdapter(
this, R.layout.row_line, contacts);
} else {
//---Honeycomb and later---

adapter = new MyClassAdapter(
this, R.layout.row_line, contacts);
}

this.setListAdapter(adapter);


}

private void PrintContacts(Cursor c) {
ContentResolver cr = getContentResolver();
//---display the contact id and name and phone number----
if (c.moveToFirst()) {
do {
//---get the contact id and name
String contactID = c.getString(c.getColumnIndex(
ContactsContract.Contacts._ID));
String contactDisplayName =
c.getString(c.getColumnIndex(
ContactsContract.Contacts.DISPLAY_NAME));
Log.v("Content Providers", contactID + ", " +
contactDisplayName);

String contactDisplayPhone = "";
//---get phone number---
int hasPhone =
c.getInt(c.getColumnIndex(
ContactsContract.Contacts.HAS_PHONE_NUMBER));
if (hasPhone == 1) {
Cursor phoneCursor =
getContentResolver().query(
ContactsContract.CommonDataKinds.Phone.CONTENT_URI, null,null
, null, ContactsContract.CommonDataKinds.Phone.DISPLAY_NAME + " ASC");
while (phoneCursor.moveToNext()) {
Log.v("Content Providers",
contactDisplayPhone = phoneCursor.getString(
phoneCursor.getColumnIndex(
ContactsContract.CommonDataKinds.Phone.NUMBER)));
}
phoneCursor.close();

}
contacts.add(new Contact(contactDisplayName, contactDisplayPhone));

} while (c.moveToNext());
}
}



public class Contact {
public String contactName = "";

public String contactNumber = "";

public Contact(String name, String number) {

contactName = name;

contactNumber = number;
}
}

public class MyClassAdapter extends ArrayAdapter<contact> {

private class ViewHolder {
private TextView name;
private TextView number;
}

public MyClassAdapter(Context context, int textViewResourceId, ArrayList<contact> items) {
super(context, textViewResourceId, items);
}

public View getView(int position, View convertView, ViewGroup parent) {
ViewHolder viewHolder;
if (convertView == null) {
convertView = LayoutInflater.from(this.getContext())
.inflate(R.layout.row_line, parent, false);

viewHolder = new ViewHolder();
viewHolder.name = (TextView) convertView.findViewById(R.id.contactName);

viewHolder.number = (TextView) convertView.findViewById(R.id.contactNumber);

convertView.setTag(viewHolder);
} else {
viewHolder = (ViewHolder) convertView.getTag();
}

Contact item = getItem(position);
if (item != null) {
viewHolder.name.setText(item.contactName);

viewHolder.number.setText(item.contactNumber);
}

return convertView;
}
}

}

What I have tried:

i tried SimpleCursorAdapter too though in that entries got alphabetical but phone numbers were not visible. you may refer to this link: http://stackoverflow.com/questions/38618185/how-should-i-solve-the-issue-of-duplicate-contact-names-and-phone-numbers-not-vi
