问我们如何动态地添加视图androidx.constraintlayout.helper.widget.Flow和添加引用Ids

EN

for (i in 0..4) {
    val customView = CustomComponent (this)
    customView.id = generateViewId()
    constraintLayout.addView(customView,i)
    flow.addView(customView)
}

<androidx.constraintlayout.widget.ConstraintLayout
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:id="@+id/constraintLayout"
    app:layout_constraintBottom_toBottomOf="parent"
    app:layout_constraintEnd_toEndOf="parent"
    app:layout_constraintStart_toStartOf="parent"
    >

    <androidx.constraintlayout.helper.widget.Flow
        android:id="@+id/flow"
        android:layout_width="0dp"

        app:layout_constraintStart_toStartOf="parent"
        />

</androidx.constraintlayout.widget.ConstraintLayout>
