添加片段时如何模糊父活动？

Question

An Activity which has an image when i click the image
1)A fragment should be added in the middle of the parent activity
2)When the fragment appears the background of parent activity should get blurred/dimmed.
3)And clicking outside the fragment the fragment should disappear again.
(Same effect we get when we click contact image in whatsApp it opens an overlay) I have can add fragment successfully but the activity remains active.

How to achieve this effect? I have tried fragmentTransaction.setCustomAnimation(int,int) but it does not work.

Thank you.

You have two options:

1. Use a DialogFragment setting the layout in the onCreateView() method.
2. Add a full screen Fragment with a background with alpha (for example #44000000 ). Add the OnTouchListener to the background view and in the onTouch() method, dismiss the Fragment .

By the way, I would seriously recommend you the first option.
