Android 在滚动视图中添加CardView

在我的应用程序中，我有一个名为

tasti.class

的类，其中我有一个简单的

布局

，其中有一个

滚动视图

和一些

CardView的

它还有一个按钮，当我按下它时，它会打开一个自定义的

AlertDialog

，所以我的问题是，在我的自定义

AlertDialog

中插入要放置在

CardView

和“Prezzo”的

TextView

中的名称后，如何添加其他

CardView

它应该是

文本视图的描述

我的意思是按下按钮“AGGIUNGI”，如何创建新的CardView并将其添加到

滚动视图的底部

？

以下是布局部分的XML代码：

在Kotlin中，您可以执行以下操作：

val mainLinearLayout = findViewById(R.id.constraintLayout) as LinearLayout
val cardLinearLayout = LinearLayout(this)
cardLinearLayout.orientation = LinearLayout.VERTICAL
val params = RelativeLayout.LayoutParams(
        ViewGroup.LayoutParams.MATCH_PARENT,
        ViewGroup.LayoutParams.WRAP_CONTENT)
params.setMargins(16,16,16,16)
val cardView = CardView(this)
cardView.radius = 15f
cardView.setCardBackgroundColor(Color.parseColor("#002388"))
cardView.setContentPadding(36,36,36,36)
cardView.layoutParams = params
cardView.cardElevation = 30f
val quote = TextView(this)
quote.text = "\"My cardview.\n";
quote.textSize = 24f
quote.setTextColor(Color.WHITE)
quote.setTypeface(Typeface.SANS_SERIF,Typeface.NORMAL)
cardLinearLayout.addView(quote)
cardLinearLayout.addView(name)
cardView.addView(cardLinearLayout)
mainLinearLayout.addView(cardView)

可能有帮助you@IonutJ.Bejan这就是我要找的谢谢！很好，快乐的编码：）这看起来不错，但我甚至不知道Kotlin：\

val mainLinearLayout = findViewById(R.id.constraintLayout) as LinearLayout
val cardLinearLayout = LinearLayout(this)
cardLinearLayout.orientation = LinearLayout.VERTICAL
val params = RelativeLayout.LayoutParams(
        ViewGroup.LayoutParams.MATCH_PARENT,
        ViewGroup.LayoutParams.WRAP_CONTENT)
params.setMargins(16,16,16,16)
val cardView = CardView(this)
cardView.radius = 15f
cardView.setCardBackgroundColor(Color.parseColor("#002388"))
cardView.setContentPadding(36,36,36,36)
cardView.layoutParams = params
cardView.cardElevation = 30f
val quote = TextView(this)
quote.text = "\"My cardview.\n";
quote.textSize = 24f
quote.setTextColor(Color.WHITE)
quote.setTypeface(Typeface.SANS_SERIF,Typeface.NORMAL)
cardLinearLayout.addView(quote)
cardLinearLayout.addView(name)
cardView.addView(cardLinearLayout)
mainLinearLayout.addView(cardView)
