如何限制EditText只在Java中输入浮点值？

EditText editText = findViewById(R.id.edit_text);
editText.addTextChangedListener(new TextWatcher() {
    @Override
    public void beforeTextChanged(CharSequence s, int start, int count, int after) {
    }

    @Override
    public void onTextChanged(CharSequence s, int start, int before, int count) {
    }

    @Override
    public void afterTextChanged(Editable s) {
        editText.removeTextChangedListener(this);

        String input = s.toString();
        if (!input.isEmpty() && !input.equals(".") && !input.equals("-")) {
            boolean isValid = true;
            String[] parts = input.split("\\.");
            if (parts.length > 2) {
                isValid = false;
            } else if (parts.length == 2) {
                String decimalPart = parts[1];
                if (decimalPart.length() > 2) {
                    isValid = false;
                }
            }

            if (!isValid) {
                editText.setText(input.substring(0, input.length() - 1));
                editText.setSelection(input.length() - 1);
            }
        }

        editText.addTextChangedListener(this);
    }
});
