It would be really cool if the project could be deployed to maven central.

Sonatype has hosting of open source maven repos: https://docs.sonatype.org/display/Repository/Sonatype+OSS+Maven+Repository+Usage+Guide http://jroller.com/holy/entry/releasing_a_project_to_maven

Hi,

Thanks for this excellent library. After the wizard process I wanna store that data but I can't figure out how to save the data.

Thanks in advance

I am trying to add image page to wizard. Pick chooser/capture works, but I don't know how to handle activity's result or set page value.

Thanks in advance!

I found, that if you place in your wizard pager amount of ImagePage, so when you will startActivityForResult returned result will overwrite every your image. I found the way to avoid this:

Changing request codes to:

private final int GALLERY_REQUEST_CODE = Math.abs((short) (hashCode() ^ (hashCode() >>> 16)) - 0);
private final int CAMERA_REQUEST_CODE = Math.abs((short) (hashCode() ^ (hashCode() >>> 16)) - 1);

This will make every ImageFragment unique. Later change onActivityResult for:

if(requestCode == CAMERA_REQUEST_CODE) {
            if (resultCode == Activity.RESULT_OK) {
                imageView.setImageURI(mNewImageUri);
                writeResult();
            }
        } else if(requestCode == GALLERY_REQUEST_CODE) {
            if (resultCode == Activity.RESULT_OK && data != null) {
                mNewImageUri = data.getData();
                imageView.setImageURI(mNewImageUri);
                writeResult();
            }
        }

I have added this project into my Android Studio like this:

compile 'com.github.TechFreak:WizardPager:1.0.3'

However, when I try to import some class, like: import com.tech.freak.wizardpager.model.AbstractWizardModel;

Android Studio says it does not found the reference. I could only import com.tech.freak.wizardpager.R without errors. What could I be doing wrong?

By the way, such a great wizard for Android! Simply the best I found on open-source community.

@TechFreak i've been working on this library for the past view days to create a student form. is there anyway i can load data from sqlite into the wizard and what the student select in the first page will determine what student see in the next page for MultipleFixedChoicePage and SingleFixedChoicePage??

All strings are in wizardpager but we cannot use a conext with getString because the initialization of the wizardmodel is static, so the application is not created yet :(

I modified library/build.gradle to produce maven artifacts in library/build/mvn-repo/, hoping this helps with #2. If you're opposed to the idea of publishing on Maven Central please consider publishing to github by creating a separate repository or special-case branch for the maven artifact. For an example of hosting maven artifacts on github please see: https://github.com/WhisperSystems/maven

This pull also makes it easy for users to package and publish their own artifact of the project but personally I would prefer to use something packaged by the author :) thanks for the great project

Hi! I know, this project is too old, but maybe something could change? Currently newest AS can not build project Maybe someone knows, how to fix? I tried to turn off jetify, added it to ignorelist, clean, invalidate.... but it doesn't help.

Hello i have multiple fixed choice like below:

((MultipleFixedChoicePage) mWizardModel.findByKey("Items"))
      .setChoices(names)
      .getAdapter().notifyDataSetChanged();

I cannot setId to each choice field. I just only can set the string name to display.

When i pass to bundle like this: Bundle bundle = mWizardModel.save();

I get the selected string by: List dealIdsString = bundle.getBundle("Items").getStringArrayList("_");

The problem is i cannot get the selected id (additional property that i wanted to add). Please help. Thanks.

In the sample code the AbstractWizardModel is being statically instantiated when MainActivity is created. Once this is done, the onNewRootPageList() callback is immediately triggered in the wizard model and I couldn't find a way to load the PageList with some dynamic contents.

The workaround I found for this is to make AbstractWizardModel class a inner class in MainActivity and have my dynamic content a global variable so I could access it from AbstractWizardModel. This generates a side effect since I'm no longer instantiating AbstractWizardModel class when the MainActivity is create. I'm instantiating it o onCreate() callback, so it is being called some time later in comparison with original code.

Is there an alternative way to load content in the form (PageList) dynamically?
