NestedScrollView中具有ConstraintLayout的最后一项未完全显示

问题描述 投票：0回答：2

我在CoordinatorLayout和CollapsingToolbarLayout上遇到问题。实际上，当我使用NestedScrollView时。我在NestedScrollView内的ConstraintLayout中放置了一个表格。最后一个按钮没有完全显示（底部隐藏了60dp）。当我单击一个按钮或编辑文本时，将显示最后一个按钮。但是当我启动应用程序时没有。

我看到了很多问题，但没有完美的答案。有人说这是CoordinateLayout的错误或问题。

这里是完整的代码：

您可以在布局的末尾添加一个空白视图。在您的按钮下。这样可以解决您的问题

尝试在约束布局中添加提交按钮下方的视图

<View
                    android:layout_width="match_parent"
                    android:layout_height="100dp"
                    app:layout_constraintBottom_toBottomOf="parent"
                    app:layout_constraintEnd_toEndOf="parent"
                    app:layout_constraintHorizontal_bias="0.0"
                    app:layout_constraintStart_toStartOf="parent"
                    app:layout_constraintTop_toBottomOf="@+id/submit"/>
