Passing data though multiple activities
(2 answers)
Closed 6 years ago.
I have three Activities.
Activity A: startActivityResult calling Activity B and getback to A
with Data
Activity B: only startActivity to Activity C and send Data to
Activity C.
Activity C: Now here i want to getData from B send to A with
startActivityResult.
How to go Activity C to A with data with
setResult(); finish();
method?
Just as you go from ActivityB to ActivityC giving data, use the same method (start intent with Bundle I suppose) to go from ActivityC to ActivityA.
In ActivityA, check if there's Bundle, and react if there's something.
If from Activity C you want to close Activity B & C and go to A then you have two choices.
startActivity A from C with Intent.FLAG_ACTIVITY_CLEAR_TOP this will call onNewIntent method from activity A and will remove all activities that are on top of activity A.
Change the implementation to have:
a. From activity B startActivityForResult(Activity C).
b. In activity C, when it's done call setResult/finish
c. In activity B, in onActivityResult check the request code, if is C request code, setResult/finish
d. Activity A it's visible again with result.
If you don't want to close Activity B & C just start the activity a and pass data to it as you start activity B.

Hey guys I have 3 activity,
Activity A -> Activity B -> Activity C
This flow I want to perform in my application. I want this scenario in my Activity C
Scenario 1
On Back press from Activity C to open Activity B then again back press then open Activity A
Scenario 2
When something submit on Activity C, I want to open Activity A and I want to hide Activity B
So how can I do this through startActivityForResult. I check through this stackoverlow, but nothing works. Thanks
I'm assuming that the 3 activities are opened in order A -> B -> C, so they are in the backstack in that order. You can check the return values from Activity C, and act accordingly.
In Activity C, setResult(Activity.RESULT_CANCELLED) during onCreate(). That will make it the default return value when activity C is closed (back press or otherwise)`.
Then setResult(Activity.RESULT_OK) whenever something is submitted. After that, you can fininsh() that activity.
Whenever Activity C get closed, in Activity B onActivityResult(), check the return value. If it's RESULT_OK, call finish() (which will return to Activity A). Otherwise, do nothing, so Activity B will stay open
I have a use-case where my Activity A will start other Activity B of some SDK, here Activity B is a transparent activity hence allowing me to still interact with A. Now from A, I start another activity C by using startActivityForResult() and from C, I am sending back the result using setResult(). But I am not able to get the result back in onActivityResult() of A.
Point to be noted here is that Activity B from other SDK is having launchmode set as "singleTask" in androidManifest file.
How I can get result back from C to A in this case?
Here is the code used in Activity A to start C :
var intent: Intent =Intent(context, ActivityC::class.java)
startActivityForResult(intent,1009)
In Activity C setting result like this :
val returnIntent = Intent()
setResult(Activity.RESULT_OK, returnIntent)
finish()
The code is okey. But the thing is, that when you start activity b, then in your stack, activity b will be the last to be created, so when you then start c, the result from c goes to b instead of a.
Try launching c before b to make sure this is the issue.
If Activity B is from another SDK and you can't control the navigation flow, then you have to store the data somewhere and check that onResume() function of Activity A.

How do I pass data between Activities in Android application?

I'm building a small quiz app with 3 activities A, B, C.
A startActivity() to B.
B has a fragment B_frag to show the quiz detail, after finish the quiz B_frag will startActivity() to C which is the result activity.
C has an option to redo the quiz which will startActivity() to B again, this time with a string through intent.putExtra().
The problem is nothing comes out of the intent.getStringExtras() on activity B after being called from C.
Can someone pls tell me why this happens and how to fix it?
From the Activity C try to use FLAG_ACTIVITY_SINGLE_TOP when you call startActivity() to start Activity B. Then in Activity B override onNewIntent() to get the new intent from Activity C.
Show us some code.
For sending data from Activity A to Activity B, try this:
intent.putExtra("someKey", yourView.getText().toString());
In Activity B:
Bundle bundle = getIntent().getExtras();
if (bundle!=null){
yourString= bundle.getString("someKey", "no name");
}
yourView.setText(yourString);
Try setting flag new task when calling startactivity from c to b.
In my activity, i'm calling activity B from activity A (in back stack A->B), than again activity C from B (in back stack A-> B-> C) for some result to reflect on activity A, than how to jump to activity A on button click with carrying some result from activity C to reflect back in activity A(while clearing back stack of activity B,C)
Option 1: You can chain calls of startActivityForResult() and "unwind" the chain in the onActivityResult() callbacks.
Activity A calls startActivityForResult() to start Activity B
Activity B calls startActivityForResult() to start Activity C
Call setResult(RESULT_OK) and then finish() in Activity C
Result of Activity C is received in onActivityResult() of Activity B. Process the result (if needed).
Call setResult(RESULT_OK) and then finish() in Activity B
Result of Activity B is received in onActivityResult() of Activity A. Process the result.
Option 2: Start Activity A again, but add flags to the intent.
Intent intent = new Intent(this, ActivityA.class);
intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
// add more data to Intent
startActivity(intent);
finish();
This intent will be received in the onNewIntent() method of Activity A.
EDIT
Option 3: Use LocalBroadcastManager to send broadcasts locally (within your process only). This requires registering a BroadcastReceiver dynamically in Activity A, then sending the broadcast from Activity C. You will still need to use one of the two techniques above to get back to Activity A and clear the stack; this just changes how the data is transmitted back to Activity A.
I have three activities, A, B and C.
User can start activity B from A, and then C from B.
I would like to have following. In C the user fill some field and click "OK"-Button. After that both activities B and C should be finished.
I don't like my idea, to finish A after starting B, then finish B after starting C, and then start A from C.
What is the best way to do that?!
Is it possible to finish parent activity from the child? If, yes, then that would be my solution. But i haven't find any information about that.
Thank you,
Mur
in Activity B, call Activity C with startActivityForResult. In the ActivityB.onActivityResult() method, call finish() when Activity C returned with a good result. This gets you back to Activity A.
try This
In Activity C Class
Intent mIntent=new Intent(getApplicationContext(),A.class).setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
startActivityForResult(mIntent);
