我无法在数组列表中绑定联系人，有人可以告诉我我做错了什么吗？

Question

            ContentResolver cr = getContentResolver();
            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));
            String name = cur.getString(cur.getColumnIndex(ContactsContract.Contacts.DISPLAY_NAME));

            c_Name.add(name);

                } }







            name_Val = (String[]) c_Name.toArray(new String[c_Name.size()]);
            //phone_Val= (String[]) c_Number.toArray(new String[c_Name.size()]);
            ArrayAdapter<String> adapter = new ArrayAdapter<String>(this,android.R.layout.simple_list_item_1,name_Val);
            txtPhoneName.setAdapter(adapter);

Answer 1

Why bind to an ArrayList? You can bind directly to cur using SimpleCursorAdapter.

what is autocompletetextView?

It's difficult to tell what exactly is going on because so much of the application is missing.

Also, what exactly are you trying to do? There may be an easier way to do it.
