[英]constraintlayout inside scrollview not scroll
在我的項目中，當我在滾動視圖中放置約束布局時，不滾動並且約束布局是固定的。 這是我的 xml 布局：

但是當我將約束轉換為線性時效果很好。 我搜索了很多主題並將 android:fillViewport="true" 放在滾動視圖中，但是如果我將滾動視圖作為根視圖，我的constraintlayout 不會滾動
使用視口為 true 的NestedScrollView
<androidx.core.widget.NestedScrollView
android:layout_width="match_parent"
android:layout_height="match_parent"
android:fillViewport="true">
<android.support.constraint.ConstraintLayout
android:layout_width="match_parent"
android:layout_height="700dp">
</android.support.constraint.ConstraintLayout>
</androidx.core.widget.NestedScrollView>
ScrollView或NestedScrollView內部的ConstraintLayout不會滾動
[英]ConstraintLayout inside ScrollView or NestedScrollView won't scroll
在 ScrollView 中垂直居中 ConstraintLayout 和可擴展的 textView（滾動/居中問題）
[英]Center vertically ConstraintLayout with expandable textViews inside ScrollView (scroll/center problem)
ScrollView 中的約束布局內的 FloatingActionButton
[英]FloatingActionButton inside constraintLayout in ScrollView
是否可以將 ConstraintLayout 放在 ScrollView 中？
[英]Is it possible to put a ConstraintLayout inside a ScrollView?
是否可以在Blueprint模式下使用ConstraintLayout滾動ScrollView？
[英]Is it possible to scroll a ScrollView with a ConstraintLayout in Blueprint Mode?
