Question

I want to show the contacts stored in android mobile while typing text in a EditText box. I want to display the contacts below the EditText box like the messaging screen. I can retrieve the contacts using ContactsContract, but I don’t know how to display like the messaging screen in Android. Does anybody know something about this?

My current code:

 Cursor cur = cr.query(ContactsContract.Contacts.CONTENT_URI,
                    null, null, null, null);
 if (cur.getCount() > 0) {
    while (cur.moveToNext()) {
        String id = cur.getString(
                        cur.getColumnIndex(ContactsContract.Contacts._ID));
        System.out.println("contactsID-->>>"+id);
        String name = cur.getString(
                        cur.getColumnIndex(ContactsContract.Contacts.DISPLAY_NAME));
        System.out.println("contactsName-->>>"+name);

        if (Integer.parseInt(cur.getString(cur.getColumnIndex(ContactsContract.Contacts.HAS_PHONE_NUMBER))) > 0) {
            Cursor pCur = cr.query(Contacts.Phones.CONTENT_URI, null, 
                                   Contacts.Phones.PERSON_ID +" = ?", 
                                   new String[]{id}, null);
            int i=0;
            int pCount = pCur.getCount();    

            while (pCur.moveToNext()) {
                String phoneNum = pCur.getString(
                                       pCur.getColumnIndex(Contacts.Phones.NUMBER));
                System.out.println("PhoneNum-->>>"+phoneNum);
            }

            // Query phone here.  Covered next
        }
    }
}

You need to use AutoCompleteTextView and use the contact names read from ContactsContract to populate the adapter. Code:

    String CONTACTS[] = null;
    Cursor contactsCursor  = getContentResolver().query(ContactsContract.Contacts.CONTENT_URI, new String[]{Contacts.DISPLAY_NAME}, null, null, null);
    if(contactsCursor!=null){
        CONTACTS = new String[contactsCursor.getCount()];//(contactsCursor.getCount())];
        int i=0;
        while(contactsCursor.moveToNext()) {
            CONTACTS[i] = contactsCursor.getString(contactsCursor.getColumnIndex(Contacts.DISPLAY_NAME));
            i++;
        }
    }
    ArrayAdapter<String> adapter = new ArrayAdapter<String>(this,
            android.R.layout.simple_dropdown_item_1line, CONTACTS);
    AutoCompleteTextView textView = (AutoCompleteTextView)
            findViewById(R.id.autocompleteTextView);
    textView.setAdapter(adapter);
