当softKeyBoard隐藏按钮和其他元素时如何使布局可滚动[ANDROID]

Question

我的目标是制作带有页脚文本的登录用户界面，而且页面应该是可滚动的，只要内容不会显示在视图上。

我在布局中添加了滚动视图，但是当键盘出现时，滚动不起作用任何建议？那些不起作用，我不希望那个按钮出现在键盘上方

<LinearLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical">

    <androidx.core.widget.NestedScrollView
        android:layout_width="match_parent"
        android:layout_height="0dp"
        android:layout_weight="1"
        android:fillViewport="true">

           <androidx.constraintlayout.widget.ConstraintLayout
               android:layout_width="match_parent"
               android:layout_height="match_parent">

              <View
                 android:id="@id/view_1"
                 ...
                 app:layout_constraintTop_toTopOf="parent" />

              <View
                 android:id="@id/view_2"
                 ...
                 app:layout_constraintTop_toBottomOf="@id/view_1" />

              <View
                 android:id="@id/view_3"
                 ...
                 app:layout_constraintTop_toBottomOf="@id/view_2" />

              <View
                 android:id="@id/view_4"
                 ...
                 app:layout_constraintTop_toBottomOf="@id/view_3"
                 app:layout_constraintBottom_toBottomOf="parent" />

           </androidx.constraintlayout.widget.ConstraintLayout>
    </androidx.core.widget.NestedScrollView>
</LinearLayout>

确保在所有视图（父顶部和父底部）之间都有约束。 从我的示例中，您可以看到约束 PARENT_TOP PARENT_BOTTOM
