Android 如何让scrollView在点击editText时自动滚动到底部？

Question

我给你们看下面布局的正常视图：

Image 1

当我点击email editText时弹出软键盘，编辑文本被软键盘覆盖，如下图所示：

所以，我想点击 editText，scrollView 会自动滚动到底部，而不是被软键盘覆盖，如下图所示：

Answer 1

试试这个用途让你的 ScrollView android:fillViewport="true"

android:fillViewport="true"

Defines whether the scrollview should stretch its content to fill the viewport.

并在您的清单文件中添加 android:windowSoftInputMode="adjustResize" 在您的登录 activity

android:windowSoftInputMode="adjustResize"

The activity's main window is always resized to make room for the soft keyboard on screen

<activity
    android:name=".activities.LoginActivity"
    android:windowSoftInputMode="adjustResize"/>

Answer 2

添加你的Scrollview：

android:fillViewport="true"

并添加到您的 Manifest 文件中：

android:windowSoftInputMode="adjustResize"
