如何在父母布局的右上角添加兩個浮動操作按鈕（一半為內部布局，一半為外部），並在單擊時顯示

Question

我想當用戶單擊自定義表格視圖的特定行以在父級布局的右上角位置顯示兩個浮動按鈕時，在布局中顯示一半，在布局外部顯示一半。

這是示例：

考慮到底部布局在我的情況下是表格視圖的行，

這是我要添加晶圓廠的布局：

android:visibility="visible">

<LinearLayout
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_weight="1"
    android:orientation="vertical">

    <LinearLayout
        android:id="@+id/tvLAyout"
        android:layout_width="wrap_content"
        android:layout_height="match_parent"
        android:layout_weight="1"

您可以嘗試以下代碼：

    <?xml version="1.0" encoding="utf-8"?>

    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:background="#E0E0E0">

    <RelativeLayout
        android:id="@+id/top_card"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:elevation="4dp">

        <ImageView

        <!-- Back button -->
