SmartBackgroundManager

SmartBackgroundManager allows to easily change the background of your Leanback app and apply blur to it using RxJava2. Glide and Picasso are also supported.

Getting Started

Add the JCenter repository to your app-module or project:

repositories {
    jcenter()
}

And then add the dependencies:

implementation "uz.pentoligy.leanback:smartbackgroundmanager:1.0"

If you want to use Glide or Picasso, add one of the following dependencies:

// for Glide
implementation "uz.pentoligy.leanback:smartbackgroundmanager-glide:1.0"
implementation "com.github.bumptech.glide:glide:$latestVersion"
kapt "com.github.bumptech.glide:compiler:$latestVersion"

// for Picasso
implementation "uz.pentoligy.leanback:smartbackgroundmanager-picasso:1.0"
implementation "com.squareup.picasso:picasso:$latestVersion"

Library dependencies

implementation "androidx.leanback:leanback:$latestVersion"
implementation "io.reactivex.rxjava2:rxandroid:$latestVersion"
implementation "io.reactivex.rxjava2:rxjava:$latestVersion"

Note, that library requires minimum SDK version 17 or higher.

Usage

• Creating an instance:

  • Simple without blurring:

  val backgroundManager: SmartBackgroundManager =
         SmartBackgroundManager.Builder(requireActivity()).build()

  • Simple with blurring:

  val backgroundManager: SmartBackgroundManager =
         SmartBackgroundManager.Builder(this)
                 .withRenderScriptOptions()
                 .build()

  • Advanced:

  val options: RenderScriptOptions =
         RenderScriptOptions.Builder(requireContext())
                 .withBlurScale(0.5f)
                 .withBlurRadius(10f)
                 .build()
  
  val backgroundManager: SmartBackgroundManager =
          SmartBackgroundManager.Builder(this)
                 .withRenderScriptOptions(options)
                 .withUpdateDelay(200)
                 .build()
                 

• Applying background:

  • From ImageCardView:

  (itemViewHolder?.view as? ImageCardView)?.let {
       backgroundManager.fromImageCardView(it)
  }

  • From Bitmap:

  backgroundManager.fromBitmap(bitmap)

  • From Drawable:

  backgroundManager.fromDrawable(drawable)
  // or
  backgroundManager.fromDrawable(R.id.drawable)

  • From color resource:

  backgroundManager.fromColor(R.color.color)

• If you want to use Glide or Picasso:

  // for Glide:
  private val glideTarget: SmartBackgroundManagerGlideTarget by lazy {
        SmartBackgroundManagerGlideTarget(backgroundManager)
  }
  
  ...
  
  Glide.with(requireActivity()).asBitmap().load(url).into(glideTarget)

  // for Picasso:
  private val picassoTarget: SmartBackgroundManagerPicassoTarget by lazy {
        SmartBackgroundManagerPicassoTarget(backgroundManager)
  }
  
  ...
  
  val width: Int = backgroundManager.displayWidth
  val height: Int = backgroundManager.displayHeight
  
  Picasso.get().load(url)
          .resize(width, height).centerCrop().into(picassoTarget)

To avoid memory leaks, you must set following in your Activity/Fragment:

override fun onDestroy() {
     backgroundManager.onDestroy()
     super.onDestroy()
}

Please, check the sample app for more library usages.
