Vanishing fields inside custom Dialog

I've tried to create custom Dialog with ImageView, 2 xTextViews, 3 xRadioButtons and 2xButtons. Of course I couldn't make it as regular Dialog (because of variety of Views used), so I've decided to create custom layout and a Class which would take care of setting it all up. Everything seemed to be fine, until I builded it.
Dialog showed only ImageView and first TextView but other Views were gone.

DialogBox

Should look like this:

Thats my code - layout:

Class:

public class DialogCreator extends Dialog {
    public DialogCreator(@NonNull Context context) {
        super(context);
    }

    public void showSwitchDialog(Context context, String taskID, boolean isCoordinator, View.OnClickListener posButtonClickListener){
        final Dialog dialog = new Dialog(context);
        dialog.requestWindowFeature(Window.FEATURE_NO_TITLE);
        dialog.setCancelable(false);

        dialog.setContentView(R.layout.dialog_switch_service);
        TextView task = dialog.findViewById(R.id.textView);
        TextView chooseOptionText = dialog.findViewById(R.id.textView2);
        Button cancelButton = dialog.findViewById(R.id.button);
        Button okButton = dialog.findViewById(R.id.button4);
        RadioButton redirect = dialog.findViewById(R.id.radioButton4);

        if(!isCoordinator) redirect.setVisibility(View.GONE);
        okButton.setOnClickListener(posButtonClickListener);

        task.setText("ID: " + taskID);
        chooseOptionText.setText("Choose option:");
        cancelButton.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                dialog.dismiss();
            }
        });
        dialog.show();

    }
}

Method call (dialog show):

DialogCreator dc = new DialogCreator(MainScreenActivity.this);
                dc.showSwitchDialog(MainScreenActivity.this, "000000", true,  new View.OnClickListener() {
                    @Override
                    public void onClick(View v) {
                        RadioButton radioAccept = v.findViewById(R.id.radioButton);
                        RadioButton radioDecline = v.findViewById(R.id.radioButton2);
                        RadioButton radioRedirect = v.findViewById(R.id.radioButton4);

                        if(radioAccept.isChecked()){
                            Toast.makeText(MainScreenActivity.this, "Accept", Toast.LENGTH_SHORT).show();
                        }
                        if(radioDecline.isChecked()){
                            Toast.makeText(MainScreenActivity.this, "Decline", Toast.LENGTH_SHORT).show();
                        }
                        if(radioRedirect.getVisibility() != View.GONE){
                            if (radioRedirect.isChecked()){
                                Toast.makeText(MainScreenActivity.this, "Redirect", Toast.LENGTH_SHORT).show();
                            }
                        }

                    }
                });

Everything seems to be fine (in my humble opinion) but I don't know if there is something wrong or missing or I can't just use Dialog this way. If this is right approach it would be great for me, because i could replace all Dialogs I have used before with my custom versions and that would make app a bit nicer, and clear.

Solution

  • Well you can use DialogFragment for this.

    DialogCreator.java

    public class DialogCreator extends DialogFragment {

    private static final String TASK_ID_KEY = "taskID";
    private static final String COORDINATOR_KEY = "isCoordinator";

    @Override
    public void onCreate(@Nullable Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setCancelable(false);
        setStyle(DialogFragment.STYLE_NORMAL, R.style.FullScreenDialogStyle);
    }

    public static DialogCreator newInstance(String taskID, boolean isCoordinator) {
        DialogCreator creator = new DialogCreator();
        Bundle bundle = new Bundle();
        bundle.putString(TASK_ID_KEY, taskID);
        bundle.putBoolean(COORDINATOR_KEY, isCoordinator);
        creator.setArguments(bundle);
        return creator;
    }

    @Nullable
    @Override
    public View onCreateView(@NonNull LayoutInflater inflater, @Nullable ViewGroup container, @Nullable Bundle savedInstanceState) {
        return inflater.inflate(R.layout.dialog, container, false);
    }

    @Override
    public void onViewCreated(@NonNull View view, @Nullable Bundle savedInstanceState) {
        super.onViewCreated(view, savedInstanceState);

        TextView task = view.findViewById(R.id.textView);
        TextView chooseOptionText = view.findViewById(R.id.textView2);
        Button cancelButton = view.findViewById(R.id.button);
        Button okButton = view.findViewById(R.id.button4);
        final RadioButton radioAccept = view.findViewById(R.id.radioButton);
        final RadioButton radioDecline = view.findViewById(R.id.radioButton2);

        final RadioButton redirect = view.findViewById(R.id.radioButton4);

        Bundle bundle = getArguments();
        if (bundle == null) return;
        if (!bundle.containsKey(TASK_ID_KEY) || !bundle.containsKey(COORDINATOR_KEY)) return;

        boolean isCoordinator = bundle.getBoolean(COORDINATOR_KEY);
        String taskID = bundle.getString(TASK_ID_KEY);
        if (!isCoordinator) redirect.setVisibility(View.GONE);

        task.setText("ID: " + taskID);
        chooseOptionText.setText("Choose option:");
        cancelButton.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                dismiss();
            }
        });
        okButton.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                if (radioAccept.isChecked()) {
                    Toast.makeText(requireContext(), "Accept", Toast.LENGTH_SHORT).show();
                }
                if (radioDecline.isChecked()) {
                    Toast.makeText(requireContext(), "Decline", Toast.LENGTH_SHORT).show();
                }
                if (redirect.getVisibility() != View.GONE) {
                    if (redirect.isChecked()) {
                        Toast.makeText(requireContext(), "Redirect", Toast.LENGTH_SHORT).show();
                    }
                }
            }
        });
    }

    @NonNull
    @Override
    public Dialog onCreateDialog(@Nullable Bundle savedInstanceState) {
        Dialog dialog = super.onCreateDialog(savedInstanceState);
        if (dialog.getWindow() != null) {
            dialog.getWindow().setLayout(ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.MATCH_PARENT);
        }
        return dialog;
    }
}

    FullScreenDialogStyle in your styles.xml

    <style name="FullScreenDialogStyle" parent="Theme.AppCompat.Dialog">
        <item name="android:windowNoTitle">true</item>
        <item name="android:windowFullscreen">false</item>
        <item name="android:windowIsFloating">false</item>
        <item name="android:windowBackground">@android:color/white</item>
</style>

    In your activity:

    DialogCreator.newInstance("taskID",true).show(getSupportFragmentManager(),"TAG")
