android - AppCompatDialog 与 DialogFragment

Question

使用最新的AppCompat

compile "com.android.support:appcompat-v7:22.2.1"

有可用的 AppCompatDialog 和 DialogFragment 我应该选择哪一个，有什么差异或问题可以避免吗？

编辑:

我尝试通过转换现有的Dialog来使用AppCompatDialog或DialogFragment，但没有使用getDialog ().setTitle("Title") 似乎有效。

引用自Android Documentation :

A dialog is a small window that prompts the user to make a decision or enter additional information. A dialog does not fill the screen and is normally used for modal events that require users to take an action before they can proceed.

You should use a DialogFragment as a container for your dialog. The DialogFragment class provides all the controls you need to create your dialog and manage its appearance, instead of calling methods on the Dialog object.

Using DialogFragment to manage the dialog ensures that it correctly handles lifecycle events such as when the user presses the Back button or rotates the screen. The DialogFragment class also allows you to reuse the dialog's UI as an embeddable component in a larger UI, just like a traditional Fragment (such as when you want the dialog UI to appear differently on large and small screens).

注意:AppCompatDialog 是一个 Dialog 扩展。
