How to show fragment as a dialog?

Question

I have developed application in which I want to display Fragment as a dialog,

I used Tabs and Fragment in my application, I have just one activity and I replace the fragment as I need,

If we used activity then we declare "android:theme="@android:style/Theme.Dialog" in Manifest file to display activity as dialog, same thing I want to do for Fragment

Answer 1

We can show a Fragment as a dialog using two means , but a single way.

Explanation:

Way:

Extend class DialogFragment and override any one of two methods:

onCreateView() OR

onCreateDialog().

Diff. between these two:

Overriding onCreateView() will let you show a Fragment as dialog and you can make the Title text customized.

On the other hand, overriding onCreateDialog(), you can again show a fragment as dialog and here you can customize the entire dialog fragment. Means, you can inflate any view to show as dialog.

If you need any source code explaining the above text, let me know.

Note:

Using DialogFragment has a disadvantage. It doesn't handle screen orientation. And crashes the app.

So, you need to use setRetainInstance() inside onCreate() of DialogFragment class.
