I am having FragmentDetail.java file which consist of recylerview,when touch on recylerview the same fragment FragmentDetail.java is called,Same process when i repeat 4 5 times by touching two simultaneously recyler view items. It does not show the back fragment immediately.Instead it shows the fragment of recyler view items.First Fragmet contains recylerview on which click ProductMenu calls,and on Product menu recyler view click FragmentDetail.java calls.So know what my problem is that on back press fragments are not getting replace properly.Below is my code :-
FirstFragment
list_recycler.addOnItemTouchListener(new RecyclerTouchListener(getActivity(), list_recycler, new ClickListener() {
#Override
public void onClick(View view, int position) {
Fragment fragment = new ProductMenu();
fragmentManager = getActivity().getSupportFragmentManager();
fragmentTransaction = fragmentManager
.beginTransaction();
fragmentTransaction.setCustomAnimations(R.anim.slide_in, R.anim.slide_out, R.anim.slide_enter, R.anim.slide_exit);
fragmentTransaction.replace(R.id.container_body, fragment);
fragmentTransaction.addToBackStack(null);
fragmentTransaction.commit();
}
ProductMenu.java
Also contains the same code.In spite of fragment FragmentDetail fragment = new FragmentDetail();
FragmentDetail.java
FragmentDetail fragment = new FragmentDetail();
ProductsBean productsBean = arr_related_product.get(position);
fragmentManager = getActivity().getSupportFragmentManager();
//final int newBackStackLength = fragmentManager.getBackStackEntryCount() +1;
fragmentTransaction = fragmentManager
.beginTransaction();
fragmentTransaction.setCustomAnimations(R.anim.slide_in, R.anim.slide_out, R.anim.slide_enter, R.anim.slide_exit);
fragmentTransaction.replace(R.id.container_body, fragment);
fragmentTransaction.commit();
what do you mean by
:
Same process when i repeat 4 5 times by touching two simultaneously recyler view items. --> ?
At first instance i would suggest do
fragmentTransaction.add(R.id.container_body, fragment);
instead of
fragmentTransaction.replace(R.id.container_body, fragment);
Let me know if it works ,also try to explain your problem little more with help of code

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 2 fragment on one fragment activity. I have 2 fragments say new and pending but I am having problem while switching from one fragment to another while tapping of button. When I am on pending tab and then click on new tab then sometimes it shows two loader and then it still shows pending page. My both fragments are android.support.v4.app.Fragment. I am attaching screenshot of the problem while I am tapping on new tab and still showing pending tab with two loader.
code for switching between fragment
#Override
public void onClick(View v) {
if (v.equals(neww))
{
Fragment newpage = new NewPageActivity();
FragmentTransaction ft = getSupportFragmentManager().beginTransaction();
ft.replace(R.id.framelay, newpage);
ft.commit();
}
else if(v.equals(pending))
{
Fragment pendingFragment = new PendingPage();
FragmentTransaction ft = getSupportFragmentManager().beginTransaction();
ft.replace(R.id.framelay, pendingFragment);
ft.commit();
}
}
now screenshot of problem
Try this:
FragmentManager fm = getFragmentManager();
FragmentTransaction ft = fm.beginTransaction();
ft.replace(R.id.framelay, fragment);
ft.setTransition(FragmentTransaction.TRANSIT_FRAGMENT_OPEN);
ft.commit();
I have Fragment XYZFragment where i display the list view.On the Listview item click i replace the Fragment like this.
Fragment fragment=new XYZFragment();
FragmentManager fragmentManager = getFragmentManager();
FragmentTransaction ft= fragmentManager.beginTransaction();
ft.addToBackStack(null);
ft.replace(R.id.content_frame, fragment).commit();
But my problem is when i click back button the fragment reload the listview.It is never happen when i used to use Activity.
So my question is how to save the instance of previous fragment so that it will prevent the reloading of Data.
without seeing your code we can't help you out but from your question i can figure out the problem, this solution may help you out.
create stack such that
private static Stack<Fragment> myFragStack;
myFragStack = new Stack<Fragment>();
//To Load the fragment
public void loadFragment(Fragment fragment){
FragmentManager fm = getSupportFragmentManager();
FragmentTransaction ft = fm.beginTransaction();
myFragStack.lastElement().onPause();
ft.hide(myFragStack.lastElement());
myFragStack.push(fragment);
}
//onBackPressed
public void onBackPressed() {
FragmentManager fm = getSupportFragmentManager();
FragmentTransaction ft = fm.beginTransaction();
if (myFragStack.size() > 1) {
ft.remove(myFragStack.pop());
myFragStack.lastElement().onResume();
ft.show(myFragStack.lastElement());
ft.commit();
}
}
It's a sample code.. you can change it as per your requirement.
ft.replace() will completely remove the view & will lose the context so you can't maintain your list state, but using stacks maintaining fragments with hide-show will solve your problem.
I am developing a simple android app only for tablets and using android 4.0. My application have the main screen like as follow:
Oncreate() of Main Activity I am adding Fragment A in the main.xml using following code:
FragmentTransaction ft = getFragmentManager().beginTransaction();
Fragment imageFragment = new ImageFragment();
ft.replace(R.id.fragment_container, imageFragment);
ft.setTransition(FragmentTransaction.TRANSIT_FRAGMENT_FADE);
ft.addToBackStack(null);
ft.commit();
This fragment A just have only a Image view which is clickable. Now I want that when user click on Image view then another fragment (Fragment B) should call and it replace the image view. The Fragment B have a VideoView which play the video.
So My second screen should be like as follow:
My problem is I am not gettting "How to call second fragment from the first one with in main screen activity?"
I can use different activities but I do not want to do so and just want to run this using fragments.
Please guide me.
This is the simplest way:
1) Inside YourActivitycreate a method:
public void goToSecondFragment(){}
FragmentTransaction ft = getFragmentManager().beginTransaction();
Fragment secondFragment = new SecondFragment();
ft.replace(R.id.fragment_container, secondFragment);
ft.setTransition(FragmentTransaction.TRANSIT_FRAGMENT_FADE);
ft.addToBackStack(null);
ft.commit();
}
2) In your first fragment, when you want to replace it, call:
YourActivity activity = (YourActivity) getActivity();
activity.goToSecondFragment();
You can do the same using below:
Adding a fragment with maintaining a back stack
FragmentManager supportFragmentManager = getSupportFragmentManager();
supportFragmentManager.addOnBackStackChangedListener(new OnBackStackChangedListener() {
#Override
public void onBackStackChanged() {
}
});
FragmentTransaction fragmentTransaction = supportFragmentManager.beginTransaction();
fragmentTransaction.setTransition(FragmentTransaction.TRANSIT_FRAGMENT_FADE);
fragmentTransaction.addToBackStack("fragmentTag");
fragmentTransaction.replace(R.id.slate, fragment, "fragmentTag");
fragmentTransaction.commit();
And Replacing a fragment
FragmentManager supportFragmentManager = getSupportFragmentManager();
FragmentTransaction fragmentTransaction = supportFragmentManager.beginTransaction();
fragmentTransaction.setTransition(FragmentTransaction.TRANSIT_FRAGMENT_FADE);
fragmentTransaction.replace(R.id.slate, fragment, "fragmentTag");
fragmentTransaction.commit();
Should work for you.
I want to do the following. There are two fragments first and second. Necessary make the transition between them. When I go from first fragment in the second, first stored in the stack. When I click the Back button the second fragment is removed and returned first fragment from the stack. Again I can not go in the second fragment - it has been deleted. How can I solve this problem?
In main activity (callback for Fragment1):
#Override
public void onNavigate() {
FragmentTransaction ft = getFragmentManager().beginTransaction();
Fragment1 newFragment1 = (Fragment1) getFragmentManager().findFragmentByTag("frag_1");
Fragment2 newFragment2 = (Fragment2) getFragmentManager().findFragmentByTag("frag_2");
ft.replace(R.id.main, newFragment2);
ft.remove(newFragment1);
ft.addToBackStack(null);
ft.commit();
}
Fragments I added dynamically:
FragmentTransaction ft = getFragmentManager().beginTransaction();
ft.add(R.id.main, new Fragment1(), "frag_1");
ft.add(R.id.main, new Fragment2(), "frag_2");
ft.commit();
I solved this problem :). I hide first fragment and add transaction to the back stack. When I click button Back I return to fragment
#Override
public void onNavigate() {
FragmentTransaction ft = getFragmentManager().beginTransaction();
Fragment1 newFragment1 = (Fragment1) getFragmentManager().findFragmentByTag("frag_1");
ft.hide(newFragment1);
ft.addToBackStack(null);
ft.commit();
}
