Android 联系人选择器清单

Question

我正在尝试创建一个“选择多个”联系人列表，其中我可以允许用户检查多个联系人。我正在寻找的内容实际上与向多个联系人撰写消息时出现的本机活动相同。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，我使用以下代码在 ListView 上显示所有用户联系人：

                 // 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);

                    }

                });

如果您不想从头开始做所有事情，那么请随意使用我现成的库来选择多个联系人：
