键盘打开时WebView不滚动 [英] WebView doesn't scroll when keyboard opened

问题描述

我有一个包含输入表单的WebView. 当用户选择第一个输入时，将出现键盘，并将滚动WebView以便隐藏输入.我的问题出在<当点击下一个部分被遮盖的输入时，API 19 WebView不会滚动.如果我要关闭键盘然后选择输入，它将可以正确滚动.

I have a WebView that contains an input form. When the user selects the first input the keyboard appears and will scroll the WebView so that the input is uncovered. My problem is in < API 19 when tapping on the next partially obscured input the WebView doesn't scroll. If I were to close the keyboard and then select the input it would scroll correctly.

我已经阅读了很多有关活动"是否为全屏"的信息，但它将无法正常工作，但我的应用程序却无法正常工作.

I've read a lot about if the Activity is FullScreen then it won't work but my app isn't.

推荐答案

您需要添加:

android:fitsSystemWindows="true"

向您作为片段/活动的布局文件的根目录，以及:

to you root of the layout file for the fragment/activity as well as:

android:windowSoftInputMode="adjustResize"

您在清单中的活动.
