I have a multi-fragment form dividing sections of a form. When the user is finished they hit the submit button at the bottom of the screen which is owned by the hosting activity. When the user clicks submit all the fragments should send their data to the activity and then the activity handles the networking. So I have onClick listeners set for the same button in every fragment, as well as the activity. However when I hit submit onClick only runs once, in some fragment (never in the activity), when it should run 5 times (because I have 4 fragments and 1 activity). Basically I need the fragments to deal with the click and then the activity deal with the same click.
Use the Observer design pattern where the activity is the Subject and the fragments are the Observers

I am working on an android application. I have cardviews for multiple fragemnts. I have put these cardviews in the main activity. So when I pressed the cardview a fragment will open. So i will make these cardviews visibility as gone. But on back press the onResume() is not called. Hence the layout is not getting visible. I tried many things but did not work. What should I do?
From what I understand, you have an activity with a fragment. Then you load a new fragment and then you press back. This interaction will not fire the activity's onResume() because the activity has never been stopped. If there is logic you need to perform between fragments, it needs to be somewhere else. I cannot provide any more details without some more information.
I think first of all use the navigation on Android Jetpak
I'm developing an application in which I have used a tab layout, I want to refresh my fragment when I used to click on button. There is a counter on tab which shows number of users, but when I press the delete button, it delete that user but the counter remain same, to refresh it I have to again run that tab which is hard to do again and again. So is there any way to refresh it automatically with the counter value change.
I believe the tab is part of the parent activity and all other fragments are attached to it through a view pager. One of the easiest methods that you can do is write a callback to activity from fragment whenever the button is clicked and update the counter value. You can read more about it here: Fragment Communication
So I have an App that switches between activities using the onClick() method. One click takes you from the main activity to activity 1-6. Upon clicking activity 1-6, it will take you back to the main activity. I need a method that will upon clicking the main activity 3 times, will take the user to another, custom, activity.
It's a simple process, but I haven't seen any questions like this here on stack overflow.
Let's say the user presses a button which causes another activity to get launched. Now the user is in another activity. What flag do I have to add to the intent, so that the user returns to my app when pressing the back button instead of navigating down the back stack of the started activity?
From the documentation, "activities on the backstack are never rearranged."
Android documentation Tasks and BackStack
You do not have to add anything to the intent. When you navigate out of you app and start another activity to complete a task, the new activity becomes kind of like an extension of your app. Pressing the back button takes you back to your app. Read This
In my application i am using tabhost. And to control different activities i am using activity group. I have Activity A from which i am going to activity B. Activity B contains Edit Text, Spinner, Button etc. Now when i scroll the Activity B and press the device Back Button than it does not go to the previous Activity. It goes out of application.
Kindly suggest the answer.
This is the way the Activity lifecycle works for Activity Group. Try using fragments instead of activity group with your tabhost to get your movements. Also, please edit your question title to more accurately reflect the actual question.
