如何将 EditText 滚动到布局的最顶部?

How to scroll an EditText to the very top of the layout?(如何将 EditText 滚动到布局的最顶部?)

问题描述

所以我在滚动视图中有一些 ChipsInput 的布局，我只是希望这些在键盘被激活时转到最顶部

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

我尝试将 windowSoftInputMode 更改为 adjustPan 等，但它并没有让它到达最顶端，只是没有覆盖它.

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

Here's my xml layout

我只需要将它发送到布局的最顶部，这样当用户开始输入时我的可过滤列表就会出现.

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

你可以使用CoordinatorLayout 作为你的根和 NestedScrollView 在里面.

You can use CoordinatorLayout as your root and NestedScrolView in it .

CoordinatorLayout 作为 root 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，您的 NestedScrollView 包含您的布局代码.

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 .

把问题放在透视图中

CoordinaterLayout > NestedScrollView > yourLayout

改变你的布局 XMl 像下面的代码

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>
