Question

我正在尝试创建一个“选择多个”联系人列表，我可以让用户检查多个联系人。我正在寻找的是与向多个联系人撰写邮件时出现的本机活动实际上相同的东西。谢谢！

首先，您需要获取联系人列表，然后将其显示在ListView元素上。例如，我使用以下代码显示ListView上的所有用户联系人：

                 // Run query on all contacts id
                Uri uri = ContactsContract.Contacts.CONTENT_URI;
                String[] projection = new String[] { ContactsContract.Contacts._ID,
                                                ContactsContract.Contacts.DISPLAY_NAME};
                String selection = null;//ContactsContract.Contacts.HAS_PHONE_NUMBER + " = '" + ("1") + "'";
                String[] selectionArgs = null;
                String sortOrder = ContactsContract.Contacts.DISPLAY_NAME
                        + " COLLATE LOCALIZED ASC";

                ContentResolver contectResolver = getContentResolver();

                Cursor cursor = contectResolver.query(uri, projection, selection, selectionArgs,
                        sortOrder);

                //Create buffer
                final ArrayList<ContactData> bufferContacts = new ArrayList<ContactData>();

                //Load contacts one by one
                if(cursor.moveToFirst()) {
                    while(!cursor.isAfterLast()) {



                        String id = cursor.getString(cursor.getColumnIndex(ContactsContract.Contacts._ID));


                        String[] emailProj = new String[]{Email.DATA};
                        Cursor cursorEmail = contectResolver.query(Email.CONTENT_URI, emailProj,Email.CONTACT_ID + " = ? ", new String[] { id }, null);

                        String[] phoneProj = new String[]{ContactsContract.CommonDataKinds.Phone.NUMBER, ContactsContract.CommonDataKinds.Phone.DISPLAY_NAME};
                        Cursor cursorPhone = contectResolver.query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI, phoneProj,
                                ContactsContract.CommonDataKinds.Phone.CONTACT_ID + " = ?", new String[] { id }, null);

                        String firstName = "";
                        String lastName = "";
                        String email = "";
                        String displayname = "";
                        String phoneNmb = "";

                        if(cursorPhone.moveToFirst()) {
                            ///displayname = cursorPhone.getString(cursorPhone.getColumnIndex(ContactsContract.CommonDataKinds.Phone.DISPLAY_NAME));
                            phoneNmb = cursorPhone.getString(cursorPhone.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER));
                        }
                        cursorPhone.close();

                        if(cursorEmail.moveToFirst()) {
                            email = cursorEmail.getString(cursorEmail.getColumnIndex(Email.DATA));
                        }
                        cursorEmail.close();

                        displayname = cursor.getString(cursor.getColumnIndex(ContactsContract.Contacts.DISPLAY_NAME));

                        //Divide display name to first and last
                        String[] names = displayname.split("\\s+");

                        firstName = displayname;

                        if(names.length >= 1) {
                            firstName = names[0];
                        }

                        if(names.length >= 2) {
                            firstName = names[1];
                        }

                        final ContactData contactData = new ContactData(id, firstName, lastName, phoneNmb, email, allChecked);

                        bufferContacts.add(contactData);

                        //Set list view initialy
                        runOnUiThread(new Runnable() {
                            public void run() {

                                if(contactsAdapter == null) {
                                    ArrayList<ContactData> contacts = new ArrayList<ContactData>();
                                    contactsAdapter = new ContactAdapter(ContactPickerActivity.this, contacts);

                                    lvContacts.setAdapter(contactsAdapter);
                                }

                                if(bufferContacts.size() >= BUFFER_INTERVAL) {
                                    addBuffer(bufferContacts);
                                }
                            }

                        });

                        cursor.moveToNext();
                    }
                }

                cursor.close();

                runOnUiThread(new Runnable() {
                    public void run() {

                        addBuffer(bufferContacts);

                    }

                });
