I'm currently having a problem with a seemingly simple layout. I have a static header (with logo and button), a WebView and then a static footer (with centre button). There seems to be a space between these 3 I cannot remove (I made the root background red so it's obvious where the space is).

Any idea how I can make the WebView fill this entire space so this red background is gone?

Also Eclipse is giving me the following warning for my RelativeLayout blocks:

This RelativeLayout layout or its LinearLayout parent is possibly useless; transfer the background attribute to the other view

知道如何让 WebView 填满整个空间，这样红色背景就消失了吗？

您应该尝试在 webview 的布局中使用 weight 标记为 1。

或删除 webview 的布局父级并直接使用权重为 1 的 webview。
