我的表格大约有12/13个字段.我Scrollview在约束布局中使用了一个内部.下面是XML布局的层次结构.问题是,它不会滚动到底部而是仅滚动到前10个初始视图.最后3个字段被隐藏,因为视图不再滚动.

父母布局

<android.support.constraint.ConstraintLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:id="@+id/activity_register"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:focusableInTouchMode="true"
android:orientation="vertical">

<!-- Textview and a button -->

  <ScrollView
    android:id="@+id/scrollView"
    android:layout_width="0dp"
    android:layout_height="wrap_content"
    android:layout_marginBottom="10dp"
    android:layout_marginTop="10dp"
    android:orientation="vertical"
    android:overScrollMode="never"
    android:scrollbars="none"
    app:layout_constraintLeft_toLeftOf="parent"
    app:layout_constraintRight_toRightOf="parent"
    app:layout_constraintTop_toBottomOf="@+id/view"
    tools:layout_constraintBottom_creator="1"
    tools:layout_constraintLeft_creator="1"
    tools:layout_constraintRight_creator="1"
    tools:layout_constraintTop_creator="1"
    tools:layout_editor_absoluteX="0dp"
    tools:layout_editor_absoluteY="0dp">


  <android.support.constraint.ConstraintLayout
        android:id="@+id/constraintLayout"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:orientation="vertical">

                <!-- Child Views (12/13 views of the fields)-->

  </android.support.constraint.ConstraintLayout>

</ScrollView>

</android.support.constraint.ConstraintLayout>

我不明白为什么会这样.我无法滚动我的滚动视图.它有一个textView,一个imageview和几个线性布局.当我用textview替换imageview和线性布局时它正在工作.这真的很不寻常和令人沮丧.谁能帮我？这是我的代码:
