sequence-layout

Animates a progress bar to the first active step in the sequence and then periodically runs a pulse animation on that step.

Setup

Add the JitPack maven repository to your root build.gradle:

allprojects {
    repositories {
      maven { url "https://jitpack.io" }
    }
}

And then the actual library dependency to your module's build.gradle:

dependencies {
    implementation 'com.github.transferwise:sequence-layout:... // use latest version'
}

Usage

Take a look at the sample app in this repository.

In XML layout

You can define steps in your XML layout:

<com.transferwise.sequencelayout.SequenceLayout
    android:layout_width="match_parent"
    android:layout_height="wrap_content">

    <com.transferwise.sequencelayout.SequenceStep
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        app:anchor="30 Nov"
        app:title="First step"/>

    <com.transferwise.sequencelayout.SequenceStep
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        app:title="Second step"/>

    <com.transferwise.sequencelayout.SequenceStep
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        app:active="true"
        app:anchor="Today"
        app:subtitle="Subtitle of this step."
        app:title="Third step"
        app:titleTextAppearance="@style/TextAppearance.AppCompat.Title"/>

    <com.transferwise.sequencelayout.SequenceStep
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        app:title="Fourth step"/>

    <com.transferwise.sequencelayout.SequenceStep
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        app:anchor="2 Dec"
        app:title="Fifth step"/>
</com.transferwise.sequencelayout.SequenceLayout>

Programmatically

Alternatively, define an adapter that extends SequenceAdapter<T>, like this:

class MyAdapter(private val items: List<MyItem>) : SequenceAdapter<MyAdapter.MyItem>() {

    override fun getCount(): Int {
        return items.size
    }

    override fun getItem(position: Int): MyItem {
        return items[position]
    }

    override fun bindView(sequenceStep: SequenceStep, item: MyItem) {
        with(sequenceStep) {
            setActive(item.isActive)
            setAnchor(item.formattedDate)
            setAnchorTextAppearance(...)
            setTitle(item.title)
            setTitleTextAppearance()
            setSubtitle(...)
            setSubtitleTextAppearance(...)
        }
    }

    data class MyItem(val isActive: Boolean,
                      val formattedDate: String,
                      val title: String)
}

... and use it for a SequenceLayout:

val items = listOf(MyItem(...), MyItem(...), MyItem(...))
sequenceLayout.setAdapter(MyAdapter(items))
