Android WebView 硬件加速键盘故障 [英] Android WebView Hardware Accelerated Keyboard Glitch

问题描述

当 WebView 被硬件加速时，点击输入字段会导致键盘出现并且 html 被重绘并移动复制了一会儿:

When WebView is hardware accelerated, clicking on input field causes keyboard to appear and html is redrawed shifted and duplicated for a moment:

1) 当软键盘出现时，WebView 将其内容平移到左下角，然后再回到正常位置.导致简短可见的重复.

1) When soft keyboard is appearing WebView pans its content to bottom-left, then againt to normal position. Causes short view-able duplication.

2) 更改键盘时(例如 abc->numbers)内容会按键盘高度向下平移，然后返回正常位置.导致简短可见的重复.

2) When changing keyboards (ex. abc->numbers) contents are panned down by keyboard height and then back to normal position. Causes short view-able duplication.

在两台 Android 4.0 平板电脑上测试，如果关闭硬件加速，则不会出现此类故障.

Tested on two Android 4.0 tablets, if hardware accelerations is turned off no such glitches appear.

我没有找到关于此的任何信息，有人遇到过同样的问题吗?

I failed to found any information on this, has anyone experienced same problem?

推荐答案

所以我终于找到了一些解决方案:

So I finally found some solutions:

1. 整个 WebView 内容按布局边距宽度移动，因此将其设置为 0px 可以解决此问题.

android:windowSoftInputMode="adjustPan" 用于 WebView 活动.

android:windowSoftInputMode="adjustPan" for WebView activity.
