  } }

// step2. add the library in your app module implementation 'com.github.seagazer:parallaxdecoration:latestVersion'

// step3. create a parallaxdecoration for your recyclerView private val bgs = intArrayOf( R.drawable.rd_gua_seed_1, R.drawable.rd_gua_seed_2, R.drawable.rd_gua_seed_3 )

val parallaxItemDecoration = ParallaxDecoration(context).apply { setupResource(bgs.asList())// init the bitmaps of background parallax = 0.3f// set the parallax fashion(the range is [0,1]) autoFill = true// set the bitmap auto scale to fill the size of recyclerView } recycler_view.addItemDecoration(parallaxItemDecoration) ```
