正在尝试对旋转木马行为使用水平recycleview,但在横向模式下,项目显示不正确。
同样的行为也可以通过在
https://github.com/AndroidCodility/HorizontalRecyclerview
在景观中
代码直截了当且简单:
class MainActivity : AppCompatActivity() {
override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
setContentView(R.layout.activity_main)
if (Utility.isOnline(this)) {
displayList()
} else {
Toast.makeText(this, R.string.no_internet, Toast.LENGTH_SHORT).show()
}
}
private fun displayList() {
val version = ArrayList<Version>()
version.addAll(Version.getList())
recyclerView.layoutManager = LinearLayoutManager(this, LinearLayout.HORIZONTAL, false)
recyclerView.adapter = MyAdapter(version)
}
}
以及适配器:
/**
* Created by Govind on 3/7/2018.
*/
class MyAdapter(private val versionList: ArrayList<Version>) : RecyclerView.Adapter<MyAdapter.ViewHolder>() {
override fun onCreateViewHolder(parent: ViewGroup, viewType: Int): ViewHolder {
return ViewHolder(LayoutInflater.from(parent.context).inflate(R.layout.item_list, parent, false))
}
override fun onBindViewHolder(holder: ViewHolder, position: Int) {
holder.bindItems(versionList[position])
}
override fun getItemCount(): Int {
return versionList.size
}
class ViewHolder(itemView: View) : RecyclerView.ViewHolder(itemView) {
fun bindItems(version: Version) {
val textView = itemView.findViewById<TextView>(R.id.tvName)
val imageView = itemView.findViewById<ImageView>(R.id.imageView)
textView.text = version.name
Glide.with(itemView.context).load(version.url).into(imageView)
}
}
}
