How can we navigate to any step i.e. independent from other.
If there is 5 steps, so how can I jump direct to step 3 from step 1 without navigating step 2.

For example in the docs, there is a "cancel" button:

But other projects may need other views there. It would be best to add ability to apps provide their own layout there.

How to return a non boolean value, but the day of the week?

upd: not relevant now

I think it is a good start, but it would look and feel much better following the Material Design Guidelines for Vertical Steppers.

Don’t embed steppers within steppers or use multiple steppers on one page.
Vertical Stepper Form has Vertical and Horizontal progress steppers combined.

Should follow all of the Design Specs

I think this library has a ton of potential. I will try to contribute as much as possible.

Cheers

Here is an example of the closest to the guidelines that I have created.

I use the stepper to display images captured from either camera or gallery. Once an image is captured from camera or image selected from gallery.

When coming back to my apps activity with the stepper form, the following method

protected void enableStepLayout(int stepNumber, boolean smoothieEnabling)

crashes on the first line of the method as "stepLayouts" is null.

Only appears to be an issue on 4.4.2. Could a fix be applied for this when possible.

Thanks

I used this code:

`@Override
public void onSaveInstanceState(@nonnull Bundle outState) {

    //store the state of the stepper for screen rotations

    Parcelable parcelable = verticalStepperForm.onSaveInstanceState();

    //Parcelable stateOfStepper = verticalStepperForm.onSaveInstanceState();

    outState.putParcelable(STEPPER_STATE, parcelable);

    super.onSaveInstanceState(outState);

}

@Override
public void onActivityCreated(@Nullable Bundle savedInstanceState) {

    if( savedInstanceState != null &&savedInstanceState.containsKey(STEPPER_STATE)) {


        Parcelable parcelable = savedInstanceState.getParcelable(STEPPER_STATE);


        //verticalStepperForm.goToStep(stateOfStepper, false);

        //onStepOpening(stateOfStepper);

        verticalStepperForm.onRestoreInstanceState(parcelable);




    }

    super.onActivityCreated(savedInstanceState);


}

Hi,

Every time an edittext with a different input type is focused, the page scroll to the top.

For example, I have one editbox for the name and another for the age. When I type the age and the keyboard is changed, the page scroll to the top.

How can I solve this?

Cause: com.android.dex.DexException: Multiple dex files define Landroid/support/v4/os/ResultReceiver;
Error:com.android.dex.DexException: Multiple dex files define Landroid/support/v4/os/ResultReceiver;

How can I resolve this error?

Thanks about your library.

I use with androidx and after build raises this error:
Error: Program type already present: android.support.v4.os.ResultReceiver

how I fix this?

Hi,

Thank you for your work on the library ;-)

I would like to know if there is any to dynamicaly change the view content of a step to make it reflect answer of the previous steps?

Best regards

Richard

Uncompleted steps should not have alpha, but the title should stay the same, and the circle should be gray:

`val mySteps = arrayOf("Name", "Email", "Phone Number")
val colorPrimary = ContextCompat.getColor(applicationContext, R.color.colorPrimary)
val colorPrimaryDark = ContextCompat.getColor(applicationContext, R.color.colorPrimaryDark)

    VerticalStepperFormLayout.Builder.newInstance(vertical_stepper_form, mySteps, this, this)
            .primaryColor(colorPrimary)
            .primaryDarkColor(colorPrimaryDark)
            .displayBottomNavigation(true) // It is true by default, so in this case this line is not necessary
            .init()`

i try this code and get cannot add a null child view to a ViewGroup.
can you tell me where it wrong?

Hi Ernesto,

Thank you so much for this library!

Do you think if is possible to add a method that let change the font type (custom font) to the Titles and Sub titles?

Thanks again for this library, it has help me a lot.

First, thanks for making everything protected and putting things in fine grained methods so it's very easy to extend and alter the behavior of this library.

I'm not sure if this is a bug or just an improvement, but I think that the individual stepContentViews should be just the width of their parent stepContent and not wrap it's contents which is the standard behavior with addView(). This way you run into trouble if you want to make full width components inside a stepContentView without using actual dp values.

I suggest changing setUpStep(int stepNumber) to:

protected void setUpStep(int stepNumber) {
        LinearLayout stepLayout = createStepLayout(stepNumber);
        if (stepNumber < numberOfSteps) {
            // The content of the step is the corresponding custom view previously created
            RelativeLayout stepContent = (RelativeLayout) stepLayout.findViewById(R.id.step_content);
            // start new
            RelativeLayout.LayoutParams params = new RelativeLayout.LayoutParams(
                ViewGroup.LayoutParams.MATCH_PARENT,
                ViewGroup.LayoutParams.WRAP_CONTENT); 
            stepContent.addView(stepContentViews.get(stepNumber), params);
            // end new
        } else {
            setUpStepLayoutAsConfirmationStepLayout(stepLayout);
        }
        addStepToContent(stepLayout);
}

Very nice library. Can it be configured as nonlinear where user can jump around to other steps out of order?

i love your form and i would like to use it for my project. However, when i build load it anf gradle builds, i get the error message:

Error:No service of type Factory<LoggingManagerInternal> available in ProjectScopeServices.

Kindy assist me in fixing this error.

Regards.

Can you please add an option to disable the confirmation step.

nvm

Good day,

I'm getting the following error after including the library and using the layout structure described in the sample app.

Kind regards

When using the library as of 0.9.x, we need to implement a lot of ugly switches.

Code would be much nicer if we could split the step logic into their own classes and the form would handle find the current step.

I got that interface which does the job:

public interface StepperFormStep {
    String getTitle();
    String getSubtitle();
    boolean isOptional();
    View createView();
    void onStepOpening(VerticalStepperFormLayout formLayout);
}

Then I have implementations such as:

public class StoreNameStep implements StepperFormStep {
    private Context context;
    private EditText name;

    public StoreNameStep(Context context) {
        this.context = context;
    }

    @Override
    public String getTitle() {
        return context.getString(R.string.wizard_store_step_title_name);
    }

    @Override
    public String getSubtitle() {
        return null;
    }

    @Override
    public boolean isOptional() {
        return false;
    }

    @Override
    public View createView() {
        name = new EditText(context);
        return name;
    }

    @Override
    public void onStepOpening(VerticalStepperFormLayout formLayout) {
        String name = this.name.getText().toString();

        if (Strings.isNullOrEmpty(name)) {
            String errorMessage = "You must indicate a store name";
            formLayout.setActiveStepAsUncompleted(errorMessage);
        } else {
            formLayout.setActiveStepAsCompleted();
        }
    }
}

My form looks like that:

public class EditStoreForm extends AbstractStepperForm {
    public EditStoreForm(Activity activity, VerticalStepperFormLayout stepperLayout) {
        super(activity, stepperLayout);
    }

    @NonNull
    @Override
    protected List<StepperFormStep> instantiateSteps() {
        return Lists.<StepperFormStep>newArrayList(
            new StoreNameStep(context)
        );
    }

    @Override
    public void sendData() {
    }
}

Setup in my fragment is a simple one-liner:

form = new EditStoreForm(getActivity(), formLayout);

And this class does the heavy lifting (that can be re-used for all my forms, and ideally it should be hidden by your library : users should just be providing forms and form steps):

public abstract class AbstractStepperForm implements VerticalStepperForm {

    protected Context context;
    protected VerticalStepperFormLayout formLayout;
    protected List<StepperFormStep> steps;

    public AbstractStepperForm(Activity activity, VerticalStepperFormLayout formLayout) {
        this.context = activity;
        this.formLayout = formLayout;
        this.steps = Lists.newArrayList(instantiateSteps());

        VerticalStepperFormLayout.Builder builder = VerticalStepperFormLayout.Builder.newInstance(formLayout, getStepTitles(), this, activity);
        initializeBuilder(builder);
        builder.init();
    }

    @NonNull
    protected abstract List<StepperFormStep> instantiateSteps();

    protected void initializeBuilder(VerticalStepperFormLayout.Builder builder) {
        builder
                .primaryColor(ContextCompat.getColor(context, R.color.colorPrimary))
                .primaryDarkColor(ContextCompat.getColor(context, R.color.colorPrimaryDark))
                .stepsSubtitles(getStepSubtitles());
    }

    @Override
    public View createStepContentView(int stepNumber) {
        StepperFormStep step = steps.get(stepNumber);
        return step.createView();
    }

    @Override
    public void onStepOpening(int stepNumber) {
        StepperFormStep step = steps.get(stepNumber);
        step.onStepOpening(formLayout);
    }

    @NonNull
    private String[] getStepTitles() {
        Collection<String> titles = Collections2.transform(steps, new Function<StepperFormStep, String>() {
            @Nullable
            @Override
            public String apply(StepperFormStep step) {
                return step.getTitle();
            }
        });

        return titles.toArray(new String[titles.size()]);
    }

    @NonNull
    private String[] getStepSubtitles() {
        Collection<String> subtitles = Collections2.transform(steps, new Function<StepperFormStep, String>() {
            @Nullable
            @Override
            public String apply(StepperFormStep step) {
                return step.getSubtitle();
            }
        });

        return subtitles.toArray(new String[subtitles.size()]);
    }
}

Then the only callback method needed is the sendData() callback.

Is it possible to add a hook to the buttons so I can do other stuff such as communicating the info back to the API?

(In my case I need access to each button and after confirmation button as well)

When i add two stepper view form in same activity the first stepper view working fine in first stepper view i use it as follwoing
verticalStepperForm1
.setup(listner1, stepperClassObject)
.init();
In second stepper view i use it same as above but in same activity. this give me error as "This step has already been initialized"

There should be an option to not just add stepNames, but the sub titles for the steps, which are also always shown below the step titles.

If the layout for an individual step uses the height 'match_parent', views will expand for ever and navigating back to a step will open it extremely slowly. Seen on Pixel 2 (Oreo)

Current work around is to use a fixed height or wrap_content.

Perhaps the library should automatically change match_parent to wrap_content where required, because users who haven't looked at the source may not be able to find the cause

As of now the fields seems bit hardcoded, thus is it possible to make dynamic fields creation?

Is it possible?

what if i want to change button text => "CONTINUE" ??

for localization and someother reasons

    mySteps = new String[]{"Test Name", "Marks Obtained", "Total Marks", "Date"};
    int colorPrimary = ContextCompat.getColor(getApplicationContext(), R.color.colorPrimary);
    int colorPrimaryDark = ContextCompat.getColor(getApplicationContext(), R.color.colorPrimaryDark);

    VerticalStepperFormLayout verticalStepperForm =  (VerticalStepperFormLayout)findViewById(R.id.vertical_stepper_form);


    // Setting up and initializing the form
    VerticalStepperFormLayout.Builder.newInstance(verticalStepperForm, mySteps, this, this)
            .primaryColor(colorPrimary)
            .primaryDarkColor(colorPrimaryDark)
            .displayBottomNavigation(false) // It is true by default, so in this case this line is not necessary
            .init();

I am getting the error on the last line.

I have a form, dynamically created, at each stepNumber, of which the fields are required or not depending on data. On each EditText I need all the form's EditTexts to check if all required fields are filled or not, the result of which will set a step's complete status.

At the moment, on creating views for steps, I am also saving Views in HashMap against stepNumber, so I can access all the views when any field in that stepNumber is edited.

The method could be called getView(stepNumber) or getForm(stepNumber)

Couldn't resolve resource @id/down_next. (5 similar errors not shown)

I have implemented your vertical stepper form but I have one issue that I can definitely not solve : my EditText created on the steps of createStepContentView() are always empty.
Anytime, it's impossible to access to the value, even thought through a textWatcher I can have the value input.
I followed exactly what you describe on your project, that's why I have now no more idea about the origin of that problem..
I hope you can help!

There are scenarios where we need to handle the navigation of the Stepper ourself like for example when a step has two buttons, instead of having to click on one of the buttons and then click continue, we can navigate to the next step on the initial button click.

So would it be possible to hide/remove the continue button for certain steps?

Currently #212121 color is hardcoded.

Hello Ernesto,

I will probably use your component for a MVP app. Have you consider adding the option to display all steps expanded, so that the user can change the item of the step once they are already set.

Suppose this use case with 4 steps:

1. User select all steps and confirm his selections (selections are displayed in another screen as a summary).
2. User requires to update one of the selections or more (presses summary item to open the screen with the VerticalStepperLayout).
3. User changes or updates the item already set. and confirm the changes.

I was planning on using another step like a fifth step of confirmation, which shows the summary, but i think the chance of showing all expanded would be much better.

Thanks for your hard work on this.

A reference to the button itself would allow me to handle click events and also enable/disable the button. Also, how do you change the text on the confirmation button?

It would be great to have element taking the all width of the screen (MATCH_PARENT) instead of fitting the content (I'm thinking about the EditText especially) because it looks weird on tablet where there is plenty of space but the field is very short.
When I put the layout to match parent, some problems of apparition come.

When opening a step, the "Continue" button is enabled by default.
It should be enabled only when the step is completed, no?

Is it possible to change the text of the final, automatically added, step "Confirmation" and it's corresponding button? Without downloading the source that is. I could not find a way, and it's a quite vital function, especially if the app is in another language.

For example:

Circle size is 24dp but this lib is using 28dp
Circle text size is 12sp but this lib is using 16dp
Title text size is 14sp but this lib is using 17sp

It's for an application not a library ?

Good day,

Each step of mine has quite a bit of content in.
To make it easier for the user each question asked would either show or hide the following question within the step (changing the visibility of the next question from 'gone' to 'visible').
This causes the next step to be rendered in a , for the lack of a better word, squished manner.
It also causes the 'form_last_button' to disappear completely from the screen.

Edit
Is it possible to call a sort of refresh method?
As soon as I click another step, and then back to the one in question (as mentioned above) everything renders fine.

Kind regards

I am running Android N on Google Nexus 5X. I've created an Activity with few UI controls like EditText(s), Spinner and so on. Whenever I start the Activity the soft keyboard isn't shown for the first EditText but for the other EditText(s) and Spinners. It's working fine. I tried to programmatically open the soft keyboard in
onStepOpening(int) but it doesn't work.

I figured that activity_horizontal_margin is set to 64dp for w820dp-v13, which killed my layout. I had to override it in my own values-w820dp-v13. Why is this set?

Nowadays most APIs use more convenient Lists instead of arrays, so it would be great if this library would allow to feed lists directly for steps.

Hello Ernesto,

Localising the default labels used for the text elements is currently not supported. I have implemented the functionality and could provide a pull request, if you'd like to add this to the master?
