当内容被填充时，NestedScrollView自己向下滚动
当内容被填充时，NestedScrollView自己向下滚动
提问于 2015-12-22 16:04:01
我有xml，它由DrawerLayout、CoordinatorLayout和custom views、AppBarLayout、NestedScrollView组成。
问题：--当NestedtScrollView中的内容被填充时，NestedtScrollView会向下滚动。所有的研究，如scrollView.setScrollY(0)或layout_behavior = FixedScrollingViewBehavior的自定义类都帮不了我。
如何防止这种滚动

在嵌套的android:focusableInTouchMode="true"android:focusableInTouchMode="true"‘的子视图中添加android:descendantFocusability="beforeDescendants"和add和ScrollView，因为nestedScrollView在滚动之前需要聚焦一个视图。我试着将孩子们的编辑文本聚焦到焦点上
<EditText
android:id="@+id/edtAddressAccount"
style="@style/StyleEditText"
android:autofillHints=""
android:ems="10"
android:inputType="textPersonName"

app:layout_constraintEnd_toEndOf="@+id/edtDistrict"
app:layout_constraintStart_toStartOf="@+id/textView13"
app:layout_constraintTop_toBottomOf="@+id/textView13" />这里的完整代码
