I'm creating a fragment which is supposed to act like a menu. I have successfully inflated it to the activity where I wanted it to be, however I now I realise that I cannot close the fragment. Furthermore I am able to scroll the contents of the activity which the fragment is placed over. How can I edit my code in such a way that the fragment will close after an action on the activity is detected, or one of it's contents is clicked?
I created the fragment by simply adding a fragment via new -> Fragment -> Fragment(Blank). I have not touched any of the code and have initialized the fragment like so in a on click:
findViewById(R.id.Menu).setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
FragmentManager fragmentManager = getSupportFragmentManager();
FragmentTransaction fragmentTransaction = fragmentManager.beginTransaction();
fragmentTransaction.setCustomAnimations(R.anim.enter_from_left, R.anim.exit_to_left, R.anim.enter_from_left, R.anim.exit_to_left);
MenuFragment menuFragment = new MenuFragment();
fragmentTransaction.replace(android.R.id.content, menuFragment);
fragmentTransaction.commit();
}
});
This is what it looks like, ignore the horrendous design.

I have an activity with a viewpager that contains 2 tabs. Each tab is a host fragment that has 2 child fragments. First fragments are recyclerviews that open up other fragments with FragmentTransactions. I am having trouble creating different backstacks for them.
So in my recyclerview adapter in onBindViewHolder i have the onclicklistener like this:
holder.image.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
FirstFragment fragment1 = new FirstFragment();
SecondFragment fragment2 = new SecondFragment();
FragmentManager fm = ((FragmentActivity) view.getContext()).getSupportFragmentManager();
FragmentTransaction transaction = fm.beginTransaction();
transaction
.replace(R.id.frame_container, fragment2,"Tag")
.addToBackStack(null)
.commit();
}
});
If i make the transaction like this from the recyclerview, the backstack is the same for both tabs, so if i open second fragments on tab1, then on tab2, if i go back to tab1 and press back, the second fragment on tab2 gets popped insead.
If i make a button in the FirstFragment outside of the recyclerview and make the fragment transaction from FirstFragment like this:
button.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
final FragmentTransaction ft = getFragmentManager().beginTransaction();
ft.replace(R.id.frame_container, SecondFragment.newInstance(), "Tag");
ft.addToBackStack(null);
ft.commit();
}
});
then it works as intended, but i want to do it from the recyclerview.
Is there any way this can be done?
You should carry your item click listener logic into the host fragment of the tab. Then in both of your host fragments you should make required transaction by using child fragment manager. Thus, the transactions are kept in the back stack of the host fragments. Then you have to manage these different stacks which are activity's fragment stack, host1's fragment stack and host2's fragment stack. For that purpose, you have to override onBackPressed in your activity then you ask the current visible host fragment for if there is a transaction. If there is you should pop that transaction and return in onBackPressed callback.If there is no let the activity to handle event by calling super.
I don't know why my application behave in 2 different ways when i'm changing fragments. I have a menu drawer and inside a fragment i try to launch a new fragment on the same container using click event.
so when i use the menu to access to that fragment everything work well but when i try to access to the same fragment from another fragment (same container) i got on my screen both fragment overlapping.
Home fragment image
as you can see in this fragment i try to click on the bank icon to change the current fragment with another and that the result
fragment overlapping image
i'm using the fragment class to execute the click event here is the code :
cardView.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
FragmentManager fragmentManager = getActivity().getSupportFragmentManager();
FragmentTransaction ft = fragmentManager.beginTransaction();
ft.replace(R.id.nav_host_fragment, new AboutFragment());
ft.commit();
}
});
Please remember that when i access to the 2nd fragment using menu it works.
In my android activity I am using multiple fragments, I am successfully switching these fragments according to my requirement but problem is that when I am switching Fragment 1 to Fragment 2 and back from Fragment 2 to Fragment 1, Fragment 1 not showing previous data Fragment 1 start from stretch, but I want to show previous data same as I was selected.
Here is my code for go Fragment 1 (fragment_search_customerProfile) to Fragment 2 (fragment_CustomerInfo):
FragmentManager manager = getActivity().getSupportFragmentManager();
FragmentTransaction transaction = manager.beginTransaction();
transaction.replace(R.id.filterFram, new fragment_Search());
FrameLayout layout = (FrameLayout) rootView.findViewById(R.id.cpFrame);
layout.removeAllViewsInLayout();
transaction.remove(new fragment_search_customerProfile()).commit();
Here is my code for back Fragment 1 (fragment_search_customerProfile) fromFragment 2 (fragment_CustomerInfo):
FragmentManager manager = getActivity().getSupportFragmentManager();
FragmentTransaction transaction = manager.beginTransaction();
Log.d("fragment_Search", fromSearch + "");
transaction.replace(R.id.custIndoFram, new fragment_search_customerProfile());
FrameLayout layout = (FrameLayout) rootView.findViewById(R.id.custIndoFram);
layout.removeAllViewsInLayout();
transaction.remove(new fragment_CustomerInfo()).commit();
Can anyone explain me how can I stay save my fragment data?
Instead of transaction.replace(R.id.filterFram, new fragment_Search());
you can use transaction.add to add fragment while having the data of first one
transaction.add(R.id.filterFram, new fragment_Search());
transaction.addToBackStack(null);
From fragment two you can use .show instead of replace to show the first fragment
and hide fragment two from the first one. transaction.show(getSupportFragmentManager().findFragmentByTag("firstFragmentTag")).commit();
You can simple keep the instances of the fragments, so in your Activity you would have fields like that.
private Fragment fragment1;
private Fragment fragment2;
And now you can use the sexy replace() option,
To add Fragment1
if (fragment1 == null) {
fragment1 = new fragment_Search();
}
FragmentManager manager = getActivity().getSupportFragmentManager();
FragmentTransaction transaction = manager.beginTransaction();
transaction.replace(R.id.filterFram, fragment1);
and same for Fragment2
And you can hold the state of the fragment (data it retrieves) in the Fragment itself, and in your onViewCreated() you check, if the state is not null, you update the view immediately.
class Fragment1 extends Fragment {
private State state;
public void onViewCreated(View v) {
if (state != null) {
// Update UI here
}
}
}
UPDATE
Using your own code
private Fragment fragment1; // This is a field outside of below method
if (fragment1 == null) {
fragment1 = new fragment_Search();
}
FragmentManager manager = getChildFragmentManager();
FragmentTransaction transaction = manager.beginTransaction();
transaction.replace(R.id.filterFram, fragment1).commit();
FrameLayout layout = (FrameLayout) rootView.findViewById(R.id.cpFrame);
layout.removeAllViewsInLayout();
Going to fragment2 should be the same, and this code is used to go to Fragment1 and Fragment2, doesn't matter if you are going back or first time.
You have to add fragment instead of remove or replace
I have a Main Menu and created a fragment and its layout.
Now I can't seems to start fragment when user presses a button on main menu.
main menu has its own layout.
now is there anyway i could initialize it from a button?
Button bt = (Button)findViewById(R.id.button1);
bt.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
startActivity(new Intent(MainMenu.this, ExercisesFragment.class));
}
});
}
I tried it by this but it gives error saying
Fragment cannot be cast to android.app.Activity
You add fragments using fragment manager:
FragmentManager fragmentManager = getFragmentManager();
FragmentTransaction fragmentTransaction = fragmentManager.beginTransaction();
ExercisesFragment fragment = new ExercisesFragment();
fragmentTransaction.replace(R.id.fragment_container, fragment);
fragmentTransaction.commit();
read more on fragments, start here:
http://developer.android.com/guide/components/fragments.html
FragmentTransaction ft = activity.getSupportFragmentManager().beginTransaction();
ft.add(R.id.main_fragment, your_fragment);
ft.addToBackStack("ifneeded");
ft.commit();
You are doing it wrong! Intents are not used to load a fragment.
Solution is to use fragment transactions
to dynamically load the fragment you wish to bring into focus.
Here is what you need to do:
Have a container for the fragment inside the layout of you activity
Example: Assuming the layout resource of my activity is activity_main.xml, I would have a container like so
Follow this guide to create a Fragment
Assuming you already have a fragment setup with name AbcFragment, use fragment transactions to load the fragment into the container that you just created, whenever the user clicks on the button:
bt.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
getFragmentManager()
.beginTransaction()
.replace(R.id.fragment-container, new AbcFragment)
.commit();
}
});
Hi I have 5 fragments Now first time when I go to Activity of that fragments then default First fragment is called,then on first Fragment there is a button by clicking that button I go to the second fragment,similarly in Second fragment There is a button and clicking that button I go to the third fragment and so on.
Now My Question is that Current I am on Fifth fragment ,Now I want to go fifth fragment to second fragment,what should I do for this?
Can any one please tell me?
You can pop the fragment by name. While adding fragments to the back stack, just give them a name.
fragmentTransaction.addToBackStack("frag2");
Then in fragment5, pop the back stack using the name ie.. frag2 and include POP_BACK_STACK_INCLUSIVE
someButton.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
FragmentManager fm = getActivity()
.getSupportFragmentManager();
fm.popBackStack ("frag2", FragmentManager.POP_BACK_STACK_INCLUSIVE);
}
});
Here is the method to add and replace fragment.
public void addReplaceFragment(Fragment fragment, int addOrReplace) {
FragmentManager manager = getSupportFragmentManager();
FragmentTransaction transaction = manager.beginTransaction();
switch (addOrReplace) {
case addFragment:
transaction.add(R.id.frame_containerforsearchable, fragment);
transaction.commit();
break;
case replaceFragment:
transaction.replace(R.id.frame_containerforsearchable, fragment);
transaction.commit();
break;
default:
break;
}
}
call of fragment is..
addReplaceFragment(currencyFragmentWithSearch, replaceFragment);
replaceFragment integer variable
currencyFragmentWithSearch Fragment instance
You can always do this :)
getActivity().getSupportFragmentManager().replace(R.id.yourFrameLayout,new Fragment2(),"FRAG2");
OR
Fragment fragment = getActivity().getSupportFragmentManager().findFragmentByTag("FRAG2");
getActivity().getSupportFragmentManager().replace(R.id.yourFrameLayout,,"FRAG2");
Try this code:
Fragment fragment = new SecondFragmentName();
FragmentManager fm = getActivity().getSupportFragmentManager();
FragmentTransaction ft = fm.beginTransaction();
ft.replace(R.id.content_frame, fragment);
ft.commit();
just small correction to mudit_sen code. It is working, only if you add .beginTransaction. Thank you.
getActivity().getSupportFragmentManager().beginTransaction().replace(R.id.FrameLayoutId,new FragmentName()).commit();
