我在谷歌上找到了上述来源，但我不记得参考网站在哪里。对不起

使用以下代码获取使用ContentResolver的所有联系人

是的。。我可以取得联系，但无法设置为ArrayAdapter帮助我

ListView contactList = (ListView) findViewById(R.id.list_contact);
ContactsAdapter adapter = new ContactsAdapter(YourActivity.this,
            R.layout.list_contact, getContactList());
contactList.setAdapter(adapter);

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));
                  if (Integer.parseInt(cur.getString(
                        cur.getColumnIndex(ContactsContract.Contacts.HAS_PHONE_NUMBER))) > 0) {
                     Cursor pCur = cr.query(
                               ContactsContract.CommonDataKinds.Phone.CONTENT_URI,
                               null,
                               ContactsContract.CommonDataKinds.Phone.CONTACT_ID +" = ?",
                               new String[]{id}, null);
                     while (pCur.moveToNext()) {
                         String phoneNo = pCur.getString(pCur.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER));
                         Toast.makeText(NativeContentProvider.this, "Name: " + name + ", Phone No: " + phoneNo, Toast.LENGTH_SHORT).show();
                     }
                    pCur.close();
                }
            }
        }
