原题：

我想熬下来，以一个简单的例子：

I am trying to boil this down to a simple example:

我有这样一个简单的输入元素：

I have a simple input element like this:

<input class="myclass" type="text"/>

的样式看起来像：

.myclass, .myclass:focus {
   background-color: black;
}

这正常工作在Android 2.x和3.x（除已知不尊重的CSS集中输入元素的一些设备）

this works fine on android 2.x and 3.x (except some devices that are known not to respect css on focused input elements)

因为我更新了Nexus S的4.0.3我不能老是让输入字段接受任何样式。

Since I updated a nexus S to 4.0.3 I can`t get the input field to accept any styles.

一些测试显示如下： 该样式实际应用，但由于某些原因，浏览器呈现一个白色矩形在输入，渲染样式没用。使用Weinre我能移动的真正的输入元素，使我能够同时显示。

Some testing revealed the following: The styles are actually applied, but for some reasons the browser renders a white rectangle over the input, rendering styles useless. Using Weinre i was able to move the "real" input element, so that I was able to display both.

在这个任何建议都非常欢迎。

Any suggestion on this are very much welcome.

推荐答案

这个问题涉及到了Nexus S，它的表现不佳与ICS /安卓4.问题与PhoneGap的，jQuery Mobile的，煎茶的轰鸣声和震耳欲聋。从视meta标签的无视到MAL-定位z顺序，铬Android浏览器仅仅是一个大问题。

The problem is related to the Nexus S and its poor performance with ICS / Android 4. The roar of problems with Phonegap, jQuery mobile, Sencha and on is deafening. From the ignoring of Viewport meta tags to mal-positioned z-order, The Chromium Android browser is just a massive problem.

你试过关闭openGL的？

Have you tried turning off openGL?

您是否尝试过分离伪选择？

Have you tried separating the pseudo selectors?

看来，机器人的WebView不断越来越差......这是奇怪的，因为它应该会好转。我有一吨的麻烦自己带滚动和闪烁。很多框架实际上是考虑想逃在Android上。

It seems that Androids WebView is continually getting worse... which is odd as it "should" be improving. I'm having a ton of trouble myself with scrolling and flickering. A lot of frameworks are actually considering bailing on Android.
