Question

ScrollView在其中有多个linearLayouts时没有滚动。 ScrollView也在linearLayout内部。以下是我的fragment.xml代码

我正在屏幕上方和下方使用youtubePlayer，使用按钮来以滚动视图播放其他视频。

我已经搜索并进行了相应的更改，但尚未解决。

Answer 1

首先，无需将ScrollView放在LinearLayout内（因为此LinearLayout除了ScrollView之外没有其他元素）。其次，您应该将ScrollView放在FrameLayout的底部。

请参阅以下内容：

    android:layout_height="match_parent">

    <FrameLayout
        android:id="@+id/youtube_frame"
        android:layout_width="0dp"
        android:layout_height="230dp"
        app:layout_constraintEnd_toEndOf="parent"
        app:layout_constraintStart_toStartOf="parent"
        app:layout_constraintTop_toTopOf="parent" />


    <ScrollView
