如何在將清單項目 data 顯示在 RecyclerView

在MainActivity 呼叫 refresh ，將要顯示的data 寫入

 class MainActivity : AppCompatActivity() {
   adapter.refresh(
          listOf(Todo("Allen", false), Todo("John", false))
      )
     }

使用 notifyDataSetChanged()) 告知 Adapter 更新 ListView 的方法

final void notifyDataSetChanged()
Notify any registered observers that the data set has changed.

class TodoAdapter : RecyclerView.Adapter<TodoViewHolder>() {
  fun refresh(todos: List<Todo>) {
      this.todos = todos
      notifyDataSetChanged()
  }
}

建立清單每個項目，載物件資料 data class:

data class Todo(
 val name: String,
 val checked: Boolean
)

每個項目 view.xml UI

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
 xmlns:tools="http://schemas.android.com/tools"
 android:layout_width="match_parent"
 android:layout_height="wrap_content"
 android:orientation="horizontal"
 android:padding="16dp">
 <androidx.appcompat.widget.AppCompatCheckBox
     android:id="@+id/checkbox"
     android:layout_width="match_parent"
     android:layout_height="wrap_content"
     tools:text="name" />

 </LinearLayout>
