如何以编程方式将父视图添加到子视图？

Question

我想将HorizontalScrollView作为父视图添加到子视图LinearLayout 。 有没有办法在Android以编程方式将父视图添加到子视图？

Answer 1

您可以从原始父级中删除子级，将其添加到新父级，然后将新父级添加到原始父级。

就像是：

// Get reference to the child view
val childView = R.findViewById<LinearLayout>(R.id.myChildLinearLayout)

// Create horizontal scroll view (or inflate)
val horizScrollView = HorizontalScrollView(context)

// Remove child view from original parent
removeView(child)

//TODO: setup new layout params on childView as needed

// Add child view to the horizontal scroll view
horizScrollView.addView(childView)

//TODO: setup layout params on horizontal scrollview as needed

// Add horizontal scrollview to the original parent
addView(horizScollView)
