如何恢复对话框和吐司的行为？

Question

我遇到了以下问题：在 AS 打开时恢复暂停的 VM 时崩溃后，对话框和 Toasts 现在占据了整个屏幕。

以前，它们只是出现在屏幕底部的一个小方框。现在 ProgressDialogs、对话框和 toasts 具有所有屏幕行为

我正在使用 appcompat-21 来使用 Android Lollipop 的工具栏控件。我需要寻找什么？

下面是清单、主题和样式文件。

我删除了 AS 并在通过注册表清理器应用程序后重新安装（我在 windows）

Answer 1

以下项目标签真是可耻（但具有教育意义）：

<style name="AppTheme" parent="Theme.ScannerTheme">
    <item name="android:background">@drawable/bi_background</item>
</style>

是所有问题的根源，因为所有对话框都会因为应用程序的主题而获得背景。

教训是：注意你在基本主题定义中的内容...
