java - 如何从设备中获取单独的联系人姓名数组列表和联系人号码数组列表

Question

   ArrayList<String> contacts_list = new ArrayList<String>();

        Cursor c = getContentResolver().query(
                ContactsContract.CommonDataKinds.Phone.CONTENT_URI, null,
                null, null, null);
        while (c.moveToNext()) {

            contactName = c.getString(c.getColumnIndex(ContactsContract.CommonDataKinds.Phone.DISPLAY_NAME));
            PhoneNumber = c
                    .getString(c.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER));

            contacts_list.add("ContactName:"+contactName + "\n" +"ContactNumber:"+PhoneNumber );

        }

        c.close();

上面的代码中，获取了姓名和电话号码，但没有将联系电话和姓名的数组列表分开

Answer 1

创建两个列表

 ArrayList<String> contacts_name = new ArrayList<String>();
 ArrayList<String> contacts_number = new ArrayList<String>();

        Cursor c = getContentResolver().query(
                ContactsContract.CommonDataKinds.Phone.CONTENT_URI, null,
                null, null, null);
        while (c.moveToNext()) {

            contactName = c.getString(c.getColumnIndex(ContactsContract.CommonDataKinds.Phone.DISPLAY_NAME));
            PhoneNumber = c
                    .getString(c.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER));

            contacts_name.add("ContactName:"+contactName);
            contacts_number.add("ContactNumber:"+PhoneNumber );

        }

        c.close();
