推薦答案
有幾個選項.您可以使用主題并使活動的外觀和行為類似于對話框(如 <activity> 的 android:theme 屬性設置為 @android:style，使 Android Activity 看起來像對話框">this question)/Theme.Dialog 或清單中的自定義主題.
There are several options. You can use a theme and make an activity look and behave like a dialog (as in this question) by setting the android:theme attribute of your <activity> to @android:style/Theme.Dialog or a customized theme in your manifest.
或者，您可以通過將主題設置為 @android:style/Theme.Translucent.NoTitleBar 創建半透明活動，然后從活動中啟動常規對話框.正如對問題答案之一的評論所建議的那樣，在這種情況下，只要確保在對話框被關閉時 finish() 半透明活動.
Alternatively, you could create a translucent activity by setting the theme to @android:style/Theme.Translucent.NoTitleBar and then launch a regular dialog from the activity. As the comments on one of the answers to the question advise, in this case just make sure to finish() the translucent activity whenever the dialog is dismissed.
