Question

我创建了一个自定义对话框，它是一个简单的计算器。我在Android 2.3.3中遇到了布局问题。该对话框将计算器完美地包含在2.2.1及更低版本中，但在2.3.3中却没有。下面我发布了正在发生的图片和布局的XML代码。下面是关于我如何启动Dialog的代码。感谢您的帮助!!!

Answer 1

尝试将relativelayout的宽度设置为fill_parent

Answer 2

行。我发现了一个问题。在自定义对话框的onCreate（）中插入以下代码。

Window windowProperties = getWindow();
windowProperties.setBackgroundDrawable(null);

将setBackgroundDrawable（）设置为null会使背景变为不透明。这解决了这个问题，它仍适用于较低版本的Android。
