问题描述
所以我有一个在滚动视图中带有一些ChipsInput的布局，我只是希望在激活键盘时将它们移到最顶部
So I have this layout with some ChipsInput inside a scrollview and I simply want these to go to the very top when the keyboard is activated
我试图将windowSoftInputMode更改为AdjustPan等，但这并没有使其升到最高位置，只是没有涵盖它.
I've tried to change windowSoftInputMode to adjustPan and others but it does not make it to go to the very top, just doesn't cover it.
这是我的xml布局

我只需要将其发送到布局的最上方，以便当用户开始键入内容时出现我的可过滤列表.
I simply need it to be sent to the very top of the layout so my filterable list will appear when the user start to type.
推荐答案
您可以使用 NestedScrolView 在其中.
You can use CoordinatorLayout as your root and NestedScrolView in it .
CoordinatorLayout (root用户)对键盘做出反应，并使用 NestedScrollView 助手将您的布局滚动到手机顶部，其中 NestedScrollView 包括您的布局代码.
CoordinatorLayout as root reacts to keyboard and scrolls your layout to the top of your phone with assistant of NestedScrollView which your NestedScrollView includes your layout code .
将问题放入透视图
CoordinaterLayout> NestedScrolView> yourLayout
更改您的布局 XMl ，如下面的代码
Change your layout XMl like code below
<android.support.design.widget.CoordinatorLayout
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:layout_width="match_parent"
android:layout_height="match_parent">
<android.support.v4.widget.NestedScrollView
android:layout_width="match_parent"
android:layout_height="wrap_content">
<LinearLayout
android:id="@+id/constraintLayout"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="@color/background1"
android:focusable="true"
android:focusableInTouchMode="true"
android:orientation="vertical">
<!-- rest of your layout xml code-->
</android.support.v4.widget.NestedScrollView>
</android.support.design.widget.CoordinatorLayout>
