在我附加的代码中，我尝试使用两个 Android WebView（webView1 和 webView2）在 webView1 内显示启用了 javaScript 的菜单，并在 webView2 内的 webView1 中显示菜单单击结果的页面。
如代码所示，我正在动态尝试通过计算我自己的初始比例来动态地将 WebView 拟合到目标屏幕，然后在运行时将计算出的比例插入到 WebView 中。
这是我想寻求您帮助的问题...当我单击 webView1 中的菜单项以在 webView2 中显示结果时，额外的水平空白（水平空白的大小与目标屏幕，但水平滚动条大约是 webView2 的宽度）显示在 webView2 中。空白随机出现（即空白有时不出现）。
我尝试添加函数调用以清除 WebViews 缓存。水平空白在 webView2 中出现的频率较低，但问题仍然存在。
有趣的是，这仅发生在 Android 4.0+ 设备中，不会发生在操作系统为 Android 3 及以下的设备中。我们已经使用适用于 Android 4 设备的三星 Galaxy Notes II 和三星 Galaxy Tab 10.1 对此进行了测试。我们在适用于 Android 2.2 设备的华为 Ideos U8150 和适用于 Android 3 设备的无品牌设备上进行了测试。
在编译 Android 项目时，我已将最小 SDK 目标设置为 API 8，将最大 SDK 目标设置为 API 15。
我已经在互联网上（包括 StackOverflow）对这个问题进行了 2 天的广泛研究，但我找不到任何与我的问题上下文相似的帖子。
我想知道如何删除 webView2 中的水平空白。请帮忙。
谢谢。
