Challenge: RecyclerView ViewTypes (Easier probably)

[Saher.alsous]

I think i took easier approach…

i created the same view with a green background. then added requirePolice to data

data class Crime(val id: UUID = UUID.randomUUID(),
                 var title: String = "",
                 var date: Date = Date(),
                 var isSolved: Boolean = false,
                 var requirePolice : Boolean = false)

i added it to the viewmodel as 1 or 2

class CrimeListViewModel : ViewModel() {

    val crimes = mutableListOf<Crime>()

    init {
        for (i in 0 until 100) {
            val crime = Crime()
            crime.title = "Crime #$i"
            crime.isSolved = i % 2 == 0
            crime.requirePolice = i % 2 == 0
            crimes += crime
        }
    }
}

In the CrimeListFragment, I linked it this way…

  private inner class CrimeAdapter(var crimes: List<Crime>) : RecyclerView.Adapter<CrimeHolder>() {

        override fun onCreateViewHolder(parent: ViewGroup, viewType: Int)
                : CrimeHolder {
            return if (viewType == 1){
                val view = layoutInflater.inflate(R.layout.list_item_crime, parent, false)
                CrimeHolder(view)
            } else {
                val view = layoutInflater.inflate(R.layout.list_item_crime_police, parent, false)
                CrimeHolder(view)
            }
        }

        override fun onBindViewHolder(holder: CrimeHolder, position: Int) {
            val crime = crimes[position]
            holder.bind(crime)
        }

        override fun getItemCount() = crimes.size

        override fun getItemViewType(position: Int): Int {
            return when(crimes[position].requirePolice){
                true ->  1
                else ->  2
            }
        }
    }

everything else remained the same…
