在约束布局中使用 NestedScrollView 的问题
Problem in using NestedScrollView in Constraint layout
我在 NestestScrollView 中使用 Constraint 布局，如下所示。

问题是前两个 TextView 被裁剪，并且在 NestedScrollView 的底部添加了不必要的填充。
A similar bug 是几个月前提交的，但我认为它尚未解决。
之前也有人问过类似的问题，但是我找不到合适的解决方法。
看看嵌套在 NestedScrollView 中的 ConstraintLayout 上的 android:layout_gravity="center"。尝试删除此属性或将其设置为 android:layout_gravity="center_horizonal"。我不太确定在 NestedScrollView.
中垂直居中 View 是什么意思
试试这个结果 https://www.youtube.com/watch?v=PTnbzCbgBTE

在我的情况下，ConstraintLayout 的子视图中有一个app:layout_constraintBottom_toBottomOf="parent"。
<TextView
android:id="@+id/textView11"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="@string/choose_position"
app:layout_constraintBottom_toBottomOf="parent"
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintHorizontal_bias="0.061"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintTop_toBottomOf="@+id/chip_group_time"
app:layout_constraintVertical_bias="0.027" />
删除layout_constrainBottom_toBottomOf。我的 NestedScrollView 工作！！！
<TextView
android:id="@+id/textView11"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="@string/choose_position"
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintHorizontal_bias="0.061"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintTop_toBottomOf="@+id/chip_group_time"
app:layout_constraintVertical_bias="0.027" />
注意在 NestedScrollView > ConstraintLayout 中使用 app:layout_constraintBottom_toBottomOf="parent"。因为它使布局固定
我在 NestestScrollView 中使用 Constraint 布局，如下所示。

问题是前两个 TextView 被裁剪，并且在 NestedScrollView 的底部添加了不必要的填充。
A similar bug 是几个月前提交的，但我认为它尚未解决。
之前也有人问过类似的问题，但是我找不到合适的解决方法。
看看嵌套在 NestedScrollView 中的 ConstraintLayout 上的 android:layout_gravity="center"。尝试删除此属性或将其设置为 android:layout_gravity="center_horizonal"。我不太确定在 NestedScrollView.
View 是什么意思
试试这个结果 https://www.youtube.com/watch?v=PTnbzCbgBTE

在我的情况下，ConstraintLayout 的子视图中有一个app:layout_constraintBottom_toBottomOf="parent"。
<TextView
android:id="@+id/textView11"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="@string/choose_position"
app:layout_constraintBottom_toBottomOf="parent"
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintHorizontal_bias="0.061"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintTop_toBottomOf="@+id/chip_group_time"
app:layout_constraintVertical_bias="0.027" />
删除layout_constrainBottom_toBottomOf。我的 NestedScrollView 工作！！！
<TextView
android:id="@+id/textView11"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="@string/choose_position"
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintHorizontal_bias="0.061"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintTop_toBottomOf="@+id/chip_group_time"
app:layout_constraintVertical_bias="0.027" />
注意在 NestedScrollView > ConstraintLayout 中使用 app:layout_constraintBottom_toBottomOf="parent"。因为它使布局固定
