Android Keyboard Toolbar

Android keyboard toolbar is a feature that allows users to access additional functionalities and shortcuts while typing on the keyboard. This toolbar typically appears at the top of the keyboard and provides options such as emojis, stickers, GIFs, voice input, and more.

How to Implement Keyboard Toolbar in Android

To implement a keyboard toolbar in your Android app, you can use the InputConnection and InputMethodManager classes to detect keyboard events and show a customized toolbar. Here's a step-by-step guide on how to achieve this:

Step 1: Create a Custom Keyboard Toolbar Layout

First, you need to create a custom layout for your keyboard toolbar. This layout will contain the necessary buttons or options that you want to display in the toolbar. Here's an example of a simple keyboard toolbar layout:

<LinearLayout
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:orientation="horizontal">

    <Button
        android:id="@+id/emoji_button"
        android:layout_width="0dp"
        android:layout_weight="1"
        android:layout_height="wrap_content"
        android:text="😊"/>

    <Button
        android:id="@+id/sticker_button"
        android:layout_width="0dp"
        android:layout_weight="1"
        android:layout_height="wrap_content"
        android:text="Sticker"/>

    <!-- Add more buttons for other functionalities -->
</LinearLayout>

Step 2: Show Keyboard Toolbar on Keyboard Events

Next, you need to listen for keyboard events and show the custom toolbar when the keyboard is visible. You can achieve this by implementing a TextWatcher on the EditText view and showing the toolbar when the keyboard is displayed:

EditText editText = findViewById(R.id.edit_text);
InputMethodManager inputMethodManager = (InputMethodManager) getSystemService(Context.INPUT_METHOD_SERVICE);

editText.addTextChangedListener(new TextWatcher() {
    @Override
    public void beforeTextChanged(CharSequence s, int start, int count, int after) {
        // Not needed
    }

    @Override
    public void onTextChanged(CharSequence s, int start, int before, int count) {
        // Not needed
    }

    @Override
    public void afterTextChanged(Editable s) {
        if (inputMethodManager.isAcceptingText()) {
            // Show your custom toolbar
        }
    }
});

Step 3: Handle Toolbar Button Clicks

Finally, you need to handle the button clicks in your custom keyboard toolbar layout. You can set click listeners on the buttons and perform the desired actions when a button is clicked:

Button emojiButton = findViewById(R.id.emoji_button);
Button stickerButton = findViewById(R.id.sticker_button);

emojiButton.setOnClickListener(new View.OnClickListener() {
    @Override
    public void onClick(View v) {
        // Open emoji picker
    }
});

stickerButton.setOnClickListener(new View.OnClickListener() {
    @Override
    public void onClick(View v) {
        // Open sticker library
    }
});
