Edited

Here's my code >>

public class IncomeFragment extends Fragment{
    TextView title, textRsTotal;
    Dialog dialog;
    int total = 0;

    @Override
    public void onViewCreated(@NonNull View view, @Nullable Bundle savedInstanceState) {
        title = view.findViewById(R.id.totalIncomeTitle);
        Button button = view.findViewById(R.id.addIncomeBtn);
        textRsTotal = view.findViewById(R.id.totalExpenseTitle);


        dialog = new Dialog(getActivity());

        if (getActivity() != null) {
            if (!CheckInternet.isNetworkAvailable(getActivity())) {
                //show no internet connection !
            }
        }

        button.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
                dialog.setContentView(R.layout.income_custom_dialog);
                dialog.getWindow().getAttributes().windowAnimations = R.style.DialogAnimation;
                dialog.getWindow().setLayout(WindowManager.LayoutParams.MATCH_PARENT, WindowManager.LayoutParams.WRAP_CONTENT);

                RadioGroup radioGroup = dialog.findViewById(R.id.radioGroup);
                Button buttonAdd = dialog.findViewById(R.id.addBtn);
                TextInputEditText editText = dialog.findViewById(R.id.editText);

                radioGroup.clearCheck();
                radioGroup.animate();
                radioGroup.setOnCheckedChangeListener(new RadioGroup.OnCheckedChangeListener() {
                    @Override
                    public void onCheckedChanged(RadioGroup radioGroup, int checkedId) {
                        RadioButton radioButton = (RadioButton) radioGroup.findViewById(checkedId);
                    }
                });
                buttonAdd.setOnClickListener(new View.OnClickListener() {
                    @Override
                    public void onClick(View view) {
                        int selectedId = radioGroup.getCheckedRadioButtonId();
                        if (selectedId == -1) {
                            Toast.makeText(getActivity(), "Please select your income type", Toast.LENGTH_SHORT).show();
                        } else {
                            RadioButton radioButton = (RadioButton) radioGroup.findViewById(selectedId);
                            String getIncome = editText.getText().toString();
                            Toast.makeText(getActivity(), radioButton.getText() + " is selected & total is Rs."+ total, Toast.LENGTH_SHORT).show();
                        }
                    }
                });
                dialog.show();

            }
        });

        super.onViewCreated(view, savedInstanceState);
    }



    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container,
                             Bundle savedInstanceState) {
        View view = inflater.inflate(R.layout.fragment_income, container, false);


        // Inflate the layout for this fragment
        return view;
    }
}

Ok, try this :

public class IncomeFragment extends Fragment {
    TextView title, textRsTotal;
    Dialog dialog;
    int total = 0;

    @Override
    public void onViewCreated(@NonNull View view, @Nullable Bundle savedInstanceState) {
        title = view.findViewById(R.id.totalIncomeTitle);
        Button button = view.findViewById(R.id.addIncomeBtn);
        textRsTotal = view.findViewById(R.id.totalExpenseTitle);


        dialog = new Dialog(getActivity());

        if (getActivity() != null) {
            if (!CheckInternet.isNetworkAvailable(getActivity())) {
                //show no internet connection !
            }
        }

        button.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
                showDialog(new MyCallback() {
                    @Override
                    public void setText(String text) {
                        textRsTotal.setText(text);
                    }
                });
            }
        });

        super.onViewCreated(view, savedInstanceState);
    }

    private void showDialog(MyCallback myCallback) {
        dialog.setContentView(R.layout.income_custom_dialog);
        dialog.getWindow().getAttributes().windowAnimations = R.style.DialogAnimation;
        dialog.getWindow().setLayout(WindowManager.LayoutParams.MATCH_PARENT, WindowManager.LayoutParams.WRAP_CONTENT);

        RadioGroup radioGroup = dialog.findViewById(R.id.radioGroup);
        Button buttonAdd = dialog.findViewById(R.id.addBtn);
        TextInputEditText editText = dialog.findViewById(R.id.editText);

        radioGroup.clearCheck();
        radioGroup.animate();
        radioGroup.setOnCheckedChangeListener((radioGroup1, checkedId) -> {
            RadioButton radioButton = (RadioButton) radioGroup1.findViewById(checkedId);
        });
        buttonAdd.setOnClickListener(view1 -> {
            int selectedId = radioGroup.getCheckedRadioButtonId();
            if (selectedId == -1) {
                Toast.makeText(getActivity(), "Please select your income type", Toast.LENGTH_SHORT).show();
            } else {
                RadioButton radioButton = (RadioButton) radioGroup.findViewById(selectedId);
                String getIncome = editText.getText().toString();
                myCallback.setText(getIncome);
                Toast.makeText(getActivity(), radioButton.getText() + " is selected & total is Rs." + total, Toast.LENGTH_SHORT).show();
            }
        });
        dialog.show();

    }


    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container,
                             Bundle savedInstanceState) {
        View view = inflater.inflate(R.layout.fragment_income, container, false);
        return view;
    }

    public interface MyCallback {
        void setText(String text);
    }
}
