Getting Start

Dependency Setting

Step 1. Add the JitPack repository in your root project’s build.gradle file :

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

Step 2. Add our library dependency on your project build.gradle file.

dependencies {
    implementation 'com.github.shhj1998:android-live-slider:Tag'
}

Implementation

Step 1. Create a ViewPager layout like example_page.xml which will be inside your ViewPager :

<FrameLayout
    android:id="@+id/page"
    ...>
    <ImageView
        android:id="@+id/image"
        ...></ImageView>
    <TextView
        android:id="@+id/title"
        android:text="Title"
        ...></TextView>
    <TextView
        android:id="@+id/description"
        android:text="Description"
        ...></TextView>
    ...

Step 2. Define your content type class.

data class ExampleItem (
    var title: String,
    var description: String,
    var img: Bitmap,
    ...
)

Step 3. Implement your customer PagerAdapter by inheriting the abstract class LiveSliderPagerAdapter.

class ExamplePageAdapter : LiveSliderPagerAdapter<ExampleItem, String>() {
    override fun createView(context: Context, container: ViewGroup, item: ExampleItem): View {
        val inflater: LayoutInflater = context.getSystemService(Context.LAYOUT_INFLATER_SERVICE) as LayoutInflater
        // Create and connect the view xml you want to display in the viewPager.
        val view = inflater.inflate(R.layout.example_page, container, false)
        // Put the item data into the view object you want.
        view.title.text = item.title                    
        view.image.setImageBitmap(item.img)
        ...
        return view
    }
    // Try adding an animation to the view object.
    override fun startAnimation(context: Context, view: View) {
        view.image.startAnimation(AnimationUtils.loadAnimation(context, R.anim.zoom))
        ...
    }
    override fun stopAnimation(context: Context, view: View) {
        view.image.clearAnimation()
        ...
    }
}

Step 4. Apply the LiveSliderAdapter and your custom LiveSliderPagerAdapter on your RecycleView.

mRecyclerView = findViewById(R.id.recycler_view)
...
// definition of your recyclerview adapter
mExampleAdapter = LiveSliderAdapter(applicationContext, ExamplePageAdapter(), true)
mExampleAdapter.setHasStableIds(true)
mRecyclerView.adapter = mExampleAdapter
// If the ViewPager shown in RecycleView changes, start the animation.
mRecyclerView.addOnScrollListener(object : RecyclerView.OnScrollListener() {
    override fun onScrollStateChanged(recyclerView: RecyclerView, newState: Int) {
        super.onScrollStateChanged(recyclerView, newState)
        if(newState == RecyclerView.SCROLL_STATE_IDLE) {
            val layoutManager = recyclerView.layoutManager as LinearLayoutManager
            val animationItemPosition = layoutManager.findFirstCompletelyVisibleItemPosition()
            mExampleAdapter.startAnimation(animationItemPosition)
        }
    }
})

Step 5. Set your recyclerview data with your contents.

When you call the setFeedData() function with parsed contents data, it applies immediately to the live-slider recyclerview.

var mSampleData: Array<LiveSliderFeed<ExampleItem, String>>
...
mExampleAdapter!!.setFeedData(mSampleData)

Finish!
