在Kotlin ArrayAdapter中需要（上下文上下文，int资源）作为参数，但是我想要作为ArrayList中的字符串，h怎么做？

Question

class Word(var mDefultTranslation: String, var mArabicTranslation: String ) {
      fun Word (defultTranslation : String , arabicTranslation : String  ){
          mDefultTranslation = defultTranslation
          mArabicTranslation = arabicTranslation
      } 
}

val words = arrayListOf<Word>()
words.add( Word("one","two" ))  
val wordAdapter = WordAdapter (this, word??)

Answer 1

如果您只想使用带有ArrayAdapter的ListView ，则可以使用以下方法入门：

    val adapter = object : ArrayAdapter<Word>(this, android.R.layout.simple_list_item_2, android.R.id.text1, words) {
        override fun getView(position: Int, convertView: View?, parent: ViewGroup?): View {
            val view = super.getView(position, convertView, parent)
            val text1 = view.findViewById(android.R.id.text1) as TextView
            val text2 = view.findViewById(android.R.id.text2) as TextView
            text1.setText(words[position].mDefultTranslation)
            text2.setText(words[position].mArabicTranslation)
            return view
        }
    }
    listview.adapter = adapter

Answer 2

将第三个参数放入您的WordAdapter 。

class WordAdapter(context: Context, @LayoutRes resource: Int, private val wordList: ArrayList<Word>) : ArrayAdapter<Word>(context, resource)
