How can I get data back from an activity as well as Fragments?

Question

I have two activities:

• SetActivity.java
• GetActivity.java

On SetActivity.java , I've loaded a fragment Frag1.

I can load Frag2 using a button of Frag1, but as I pressed the back button, I need to get data returned from Frag2 to Frag1 or GetActivity.java to SetActivity.java.

How can I do this?

SetActivity.java -> Frag1.java(send data) -> Frag2.java(get data) -> Frag1.java(get updated data from Frag2.java)

SetActivity.java (set data) -> GetActivity.java (get data) -> SetActivity.java (Get updated data back)

How to do this?

Answer 1

Use Intents to do that.

You can pass data using intent.putExtra in the first fragment and receive it by intent.getExtra in the second fragment.
