InlineKeyboard in Telegram Bots
InlineKeyboard - a keyboard tied to a message using a callback (CallbackQuery) instead of sending a message from an ordinary keyboard.
First, create a project on Maven and add the " Telegram Bots " repository:
')
Using BotFather, register the bot and get the token:
Next, we create the class Bot, inherit from TelegramLongPollingBot and Ovveraidaim methods:
Create final variables with the bot name and token, add the botUserName method to the getBotUsername () method, and get the to getBotToken () method. In the main method, we register the bot:
The bot frame is ready! Now we will write a method with InlineKeyboard.
Create a keyboard layout object:
Now we build the position of the buttons.
Create an InlineKeyboardButton object that has 2 parameters: Text (What will be written on the button itself) and CallBackData (What will be sent to the server when the button is pressed).
Add it to the list, thus creating a series.
If you want to create another row, just make another list and add new buttons to it.
After that we need to integrate the rows, so we create a list of rows.
Feature
The developer took care of us and we can immediately write the buttons to the list without creating a variable.
Now we can set the buttons in the keyboard layout object.
If the description of working with the creation of the keyboard is not clear enough, here is the scheme:
That's all! Now add the markup to the message:
Now we can send, here's your ready method:
We make an option when the method is called in the onUpdateReceived request handler:
We try!
Now we need to handle making a new branch in if and processing CallbackQuery:
Check!

Example
Creating a bot frame
First, create a project on Maven and add the " Telegram Bots " repository:
')
<dependency> <groupId>org.telegram</groupId> <artifactId>telegrambots</artifactId> <version>4.0.0</version> </dependency> Using BotFather, register the bot and get the token:
Screen
Next, we create the class Bot, inherit from TelegramLongPollingBot and Ovveraidaim methods:
Source
import org.telegram.telegrambots.bots.TelegramLongPollingBot; import org.telegram.telegrambots.meta.api.objects.Update; public class Bot extends TelegramLongPollingBot { @Override public void onUpdateReceived(Update update) { } @Override public String getBotUsername() { return null; } @Override public String getBotToken() { return null; } } Create final variables with the bot name and token, add the botUserName method to the getBotUsername () method, and get the to getBotToken () method. In the main method, we register the bot:
Source
import org.telegram.telegrambots.bots.TelegramLongPollingBot; import org.telegram.telegrambots.meta.TelegramBotsApi; import org.telegram.telegrambots.meta.api.objects.Update; import org.telegram.telegrambots.meta.exceptions.TelegramApiRequestException; public class Bot extends TelegramLongPollingBot { private static final String botUserName = "Habr_Inlinebot"; private static final String token = "632072575:AAG5YNl9tM9MJbnP5HwLB22rVzNCmY05MQI"; public static void main(String[] args) { ApiContextInitializer.init(); TelegramBotsApi telegramBotsApi = new TelegramBotsApi(); try { telegramBotsApi.registerBot(new Bot()); } catch (TelegramApiRequestException e) { e.printStackTrace(); } } @Override public void onUpdateReceived(Update update) { } @Override public String getBotUsername() { return botUserName; } @Override public String getBotToken() { return token; } } The bot frame is ready! Now we will write a method with InlineKeyboard.
Work with InlineKeyboard
Create a keyboard layout object:
InlineKeyboardMarkup inlineKeyboardMarkup =new InlineKeyboardMarkup(); Now we build the position of the buttons.
Create an InlineKeyboardButton object that has 2 parameters: Text (What will be written on the button itself) and CallBackData (What will be sent to the server when the button is pressed).
InlineKeyboardButton inlineKeyboardButton = new InlineKeyboardButton(); inlineKeyboardButton.setText(""); inlineKeyboardButton.setCallbackData("Button \"\" has been pressed"); Add it to the list, thus creating a series.
List<InlineKeyboardButton> keyboardButtonsRow1 = new ArrayList<>(); keyboardButtons.add(inlineKeyboardButton); If you want to create another row, just make another list and add new buttons to it.
List<InlineKeyboardButton> keyboardButtonsRow2 = new ArrayList<>(); keyboardButtons.add(inlineKeyboardButton2); After that we need to integrate the rows, so we create a list of rows.
List<List<InlineKeyboardButton>> rowList= new ArrayList<>(); rowList.add(keyboardButtonsRow1); rowList.add(keyboardButtonsRow2); Feature
The developer took care of us and we can immediately write the buttons to the list without creating a variable.
keyboardButtonsRow1.add(new InlineKeyboardButton().setText("Fi4a") .setCallbackData("CallFi4a")); Now we can set the buttons in the keyboard layout object.
inlineKeyboardMarkup.setKeyboard(rowList); If the description of working with the creation of the keyboard is not clear enough, here is the scheme:
That's all! Now add the markup to the message:
SendMessage message = new SendMessage().setChatId(chatId).setText("") .setReplyMarkup(inlineKeyboardMarkup); Now we can send, here's your ready method:
Source
public static SendMessage sendInlineKeyBoardMessage(long chatId) { InlineKeyboardMarkup inlineKeyboardMarkup = new InlineKeyboardMarkup(); InlineKeyboardButton inlineKeyboardButton1 = new InlineKeyboardButton(); InlineKeyboardButton inlineKeyboardButton2 = new InlineKeyboardButton(); inlineKeyboardButton1.setText(""); inlineKeyboardButton1.setCallbackData("Button \"\" has been pressed"); inlineKeyboardButton2.setText("2"); inlineKeyboardButton2.setCallbackData("Button \"2\" has been pressed"); List<InlineKeyboardButton> keyboardButtonsRow1 = new ArrayList<>(); List<InlineKeyboardButton> keyboardButtonsRow2 = new ArrayList<>(); keyboardButtonsRow1.add(inlineKeyboardButton1); keyboardButtonsRow1.add(new InlineKeyboardButton().setText("Fi4a").setCallbackData("CallFi4a")); keyboardButtonsRow2.add(inlineKeyboardButton2); List<List<InlineKeyboardButton>> rowList = new ArrayList<>(); rowList.add(keyboardButtonsRow1); rowList.add(keyboardButtonsRow2); inlineKeyboardMarkup.setKeyboard(rowList); return new SendMessage().setChatId(chatId).setText("").setReplyMarkup(inlineKeyboardMarkup); } We make an option when the method is called in the onUpdateReceived request handler:
Source
@Override public void onUpdateReceived(Update update) { if(update.hasMessage()){ if(update.getMessage().hasText()){ if(update.getMessage().getText().equals("Hello")){ try { execute(sendInlineKeyBoardMessage(update.getMessage().getChatId())); } catch (TelegramApiException e) { e.printStackTrace(); } } } } } We try!
Now we need to handle making a new branch in if and processing CallbackQuery:
Source
@Override public void onUpdateReceived(Update update) { if(update.hasMessage()){ if(update.getMessage().hasText()){ if(update.getMessage().getText().equals("Hello")){ try { execute(sendInlineKeyBoardMessage(update.getMessage().getChatId())); } catch (TelegramApiException e) { e.printStackTrace(); } } } }else if(update.hasCallbackQuery()){ try { execute(new SendMessage().setText( update.getCallbackQuery().getData()) .setChatId(update.getCallbackQuery().getMessage().getChatId())); } catch (TelegramApiException e) { e.printStackTrace(); } } } Check!
On this, perhaps all, thank you for your attention!
