android - 如何将联系人姓名、号码、contact_id 保存到 ArrayList/联系人选择器

Question

此 Activity 正在运行，但我想将联系人信息(phone_number、name、contact_id)保存到 ArrayList 中。然后我将使用自定义适配器在复选框中列出查看此数组列表以进行多选构造。我将在程序的后期阶段使用联系信息。请帮助我提出你的想法。谢谢。

在顶部添加一个数组列表

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

然后如下改变你的while循环

 while (cursor.moveToNext()) {

            output = new StringBuffer();  //re initialize your StringBuffer again

            String contact_id = cursor.getString(cursor.getColumnIndex( _ID ));
            String name = cursor.getString(cursor.getColumnIndex( DISPLAY_NAME ));

            int hasPhoneNumber = Integer.parseInt(cursor.getString(cursor.getColumnIndex( HAS_PHONE_NUMBER )));

            if (hasPhoneNumber > 0) {

                output.append("\n First Name:" + name);


                // Query and loop for every phone number of the contact
                Cursor phoneCursor = contentResolver.query(PhoneCONTENT_URI, null, Phone_CONTACT_ID + " = ?", new String[] { contact_id }, null);

                while (phoneCursor.moveToNext()) {
                    phoneNumber = phoneCursor.getString(phoneCursor.getColumnIndex(NUMBER));
                    output.append("\n Phone number:" + phoneNumber);



                }

                phoneCursor.close();

                // Query and loop for every email of the contact
                Cursor emailCursor = contentResolver.query(EmailCONTENT_URI,    null, EmailCONTACT_ID+ " = ?", new String[] { contact_id }, null);

                while (emailCursor.moveToNext()) {

                    email = emailCursor.getString(emailCursor.getColumnIndex(DATA));

                    output.append("\nEmail:" + email);


                }

                emailCursor.close();
            }

            output.append("\n");

            arr.add(output.toString());  //add contact here in your array list.
        }

现在 arr 将包含所有联系人。
