Got it, let's work through fixing this issue step by step. The core problems you're dealing with are:

• The line feed Enter key (shown when your EditText is in a middle row) doesn't trigger your save logic
• You want data saved both when the user presses Enter (any variant) and when they navigate away from the EditText

Here's a complete, optimized solution that also ensures your EditText only accepts valid double values:

1. Enforce Double-Only Input First #

First, let's lock down the EditText to only accept valid decimal numbers to avoid parsing errors later:

// Set input type for decimal numbers
est.setInputType(InputType.TYPE_CLASS_NUMBER | InputType.TYPE_NUMBER_FLAG_DECIMAL);

// Add a filter to prevent multiple decimal points and invalid characters
est.setFilters(new InputFilter[]{new InputFilter() {
    @Override
    public CharSequence filter(CharSequence source, int start, int end, Spanned dest, int dstart, int dend) {
        String currentText = dest.toString();
        // Block multiple decimal points
        if (currentText.contains(".") && source.toString().contains(".")) {
            return "";
        }
        // Allow only digits and a single decimal point
        if (!source.toString().matches("[0-9.]")) {
            return "";
        }
        return null;
    }
}});

2. Fix Enter Key Listener to Catch All Enter Variants #

Your current listener misses the line feed Enter because it's tied to IME_ACTION_DONE. Let's adjust it to catch every Enter press, regardless of the keyboard's displayed action:

est.setOnEditorActionListener(new TextView.OnEditorActionListener() {
    @Override
    public boolean onEditorAction(TextView v, int actionId, KeyEvent event) {
        // Check for any Enter key press (including line feed and done)
        boolean isEnterTrigger = (event != null && event.getAction() == KeyEvent.ACTION_DOWN && event.getKeyCode() == KeyEvent.KEYCODE_ENTER)
                || actionId == EditorInfo.IME_ACTION_DONE
                || actionId == EditorInfo.IME_ACTION_NEXT; // Catch line feed Enter

        if (isEnterTrigger) {
            saveEditTextData(est);
            // Hide keyboard after save
            InputMethodManager inputManager = (InputMethodManager) getContext().getSystemService(Context.INPUT_METHOD_SERVICE);
            inputManager.hideSoftInputFromWindow(v.getWindowToken(), InputMethodManager.HIDE_NOT_ALWAYS);
            return true; // Consume the event to prevent default behavior
        }
        return false;
    }
});

3. Add Focus Loss Listener to Save When Navigating Away #

To cover cases where the user taps outside the EditText or switches to another input, add a focus change listener:

est.setOnFocusChangeListener(new View.OnFocusChangeListener() {
    @Override
    public void onFocusChange(View v, boolean hasFocus) {
        if (!hasFocus) {
            // Save data immediately when the EditText loses focus
            saveEditTextData((EditText) v);
        }
    }
});

4. Reusable Save Logic (Avoid Code Duplication) #

Extract your save logic into a single method to keep your code clean and maintainable:

private void saveEditTextData(EditText editText) {
    String input = editText.getText().toString().trim();
    Double damageCost = 0d;

    // Parse input safely
    if (!TextUtils.isEmpty(input)) {
        try {
            damageCost = Double.parseDouble(input);
            // Or use your existing getCleanDoubleValue() method:
            // damageCost = editText.getCleanDoubleValue();
        } catch (NumberFormatException e) {
            // Handle invalid input (optional: show feedback to user)
            Toast.makeText(getContext(), "Please enter a valid number", Toast.LENGTH_SHORT).show();
            editText.setText("0");
            damageCost = 0d;
        }
    }

    Log.d("COST", String.valueOf(damageCost));

    // Your existing validation and update logic
    if (ds.size() == 0) {
        new Handler(Looper.getMainLooper()).post(() -> {
            Toast.makeText(getContext(), "Please add damage to the vehicle to edit price", Toast.LENGTH_SHORT).show();
            editText.setText(nf.format(vehicle.getTotal()).substring(1));
            InputMethodManager inputManager = (InputMethodManager) getContext().getSystemService(Context.INPUT_METHOD_SERVICE);
            inputManager.hideSoftInputFromWindow(editText.getWindowToken(), InputMethodManager.HIDE_NOT_ALWAYS);
        });
        return;
    }

    for (Damage damage : ds) {
        if (damage == null) continue;
        for (VehicleUpdate vehicleUpdateItem : vehicleUpdate) {
            Vehicle vehicleUp = vehicleUpdateItem.vehicle;
            if (vehicleUp == null) continue;
            if (String.valueOf(damage.getVehicle()).equals(String.valueOf(vehicleUp.getUuid()))) {
                Log.d("DAMAGE UUID", String.valueOf(damage.getVehicle()));
                try {
                    vehicleUp.setTotal(Objects.requireNonNull(damageCost));
                    vehicleRepository.update(vehicleUp);
                } catch (NullPointerException e) {
                    Log.d("null", "Null pointer while updating vehicle");
                }
            }
        }
    }
}

Optional: Force Keyboard to Show Done Key (Instead of Line Feed) #

If you prefer the keyboard to always show the Done button (even for middle rows), add these lines to your EditText setup:

est.setImeOptions(EditorInfo.IME_ACTION_DONE);
est.setSingleLine(true); // Note: This makes the EditText single-line; adjust if you need multi-line support
