Question

在我的应用中，我有一个名为tasti.class的课程，其中我有一个简单的layout，其中包含ScrollView和CardView's。

它还有一个按钮，当我按下它时，它会打开一个自定义AlertDialog所以我的问题是如何在我插入自定义{{1}后添加其他CardViews要放在AlertDialog的{{1}}和＆＃34; Prezzo＆＃34;中的名称它应该是TextView的描述，我的意思是按下按钮＆＃34; AGGIUNGI＆＃34;我怎么能创建一个新的CardView并将其添加到CardView的底部？

这是布局部分的XML代码：

textView

虽然这是我ScrollView

Answer 1

在Kotlin，您可以这样做：

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)

在ScrollView中添加CardView
