Open fragment from Fragment on button click

I am having trouble opening a fragment from within another fragment on the click of a button. Everything seems to make sense (to me) and I have tried playing about with my code (changing the layouts, replacing fragments etc) but nothing is working.
Here is my RoleFragment.java (The fragment which contains the button)
public class RolesFragment extends Fragment implements View.OnClickListener {
GridView gridView;
ArrayList<Players> playersList;
MyAdapter adapter;
#Override
public View onCreateView(LayoutInflater inflater,ViewGroup container,
Bundle savedInstanceState) {
View view = inflater.inflate(R.layout.fragment_viewroles, container, false);
gridView = (GridView) view.findViewById(R.id.gv_players);
Button nightround = (Button) view.findViewById(R.id.buttonNightRound);
nightround.setOnClickListener(this);
DatabaseHelper databaseHelper = new DatabaseHelper(getActivity());
playersList = new ArrayList<Players>();
playersList = databaseHelper.getPlayers();
adapter = new MyAdapter(getActivity(), playersList);
gridView.setAdapter(adapter);
return view;
}
#Override
public void onClick(View v) {
Fragment fragment = null;
switch (v.getId()) {
case R.id.buttonNightRound:
fragment = new NightRound();
replaceFragment(fragment);
break;
}
}
public void replaceFragment(Fragment someFragment) {
FragmentTransaction transaction = getFragmentManager().beginTransaction();
transaction.replace(R.id.fragment_container, someFragment);
transaction.addToBackStack(null);
transaction.commit();
}
}
And this is my fragment_viewroles.xml file.
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"

The trouble is, when I click the button nothing happens.

There some problems here.
First, you have to add a container with the id R.id.fragment_container inside your fragment like FrameLayout
which will store your new fragment.
If your want to open a fragment as a new screen, you have to put it inside a new activity. Fragments are piece of screens and should not be used without activities or view pagers.
Have a look at the Android deverlopers page: http://developer.android.com/training/basics/fragments/communicating.html#DefineInterface
Basically, you define an interface in your Fragment A, and let your Activity implement that Interface. Now you can call the interface method in your Fragment, and your Activity will receive the event. Now in your activity, you can call your second Fragment to update the textview with the received value
// You Activity implements your interface
public class YourActivity implements FragmentA.TextClicked{
#Override
public void sendText(String text){
// Get Fragment B
FraB frag = (FragB)
getSupportFragmentManager().findFragmentById(R.id.fragment_b);
frag.updateText(text);
}
}
// Fragment A defines an Interface, and calls the method when needed
public class FragA extends Fragment{
TextClicked mCallback;
public interface TextClicked{
public void sendText(String text);
}
#Override
public void onAttach(Activity activity) {
super.onAttach(activity);
// This makes sure that the container activity has implemented
// the callback interface. If not, it throws an exception
try {
mCallback = (TextClicked) activity;
} catch (ClassCastException e) {
throw new ClassCastException(activity.toString()
+ " must implement TextClicked");
}
}
public void someMethod(){
mCallback.sendText("YOUR TEXT");
}
#Override
public void onDetach() {
mCallback = null; // => avoid leaking, thanks #Deepscorn
super.onDetach();
}
}
// Fragment B has a public method to do something with the text
public class FragB extends Fragment{
public void updateText(String text){
// Here you have it
}
}

Try something like the following:
Fragment fragment = OtherFragment.newInstance();
android.support.v4.app.FragmentTransaction transaction = getActivity().getSupportFragmentManager().beginTransaction();
transaction.replace(R.id.container_layout, fragment, "OtherFragment");// give your fragment container id in first parameter
transaction.addToBackStack(null); // if written, this transaction will be added to backstack
transaction.commit();

Reverse shared element transition on back

I am currently using the following code to transition a block on the right side of the screen to a shared element on the left:
FragmentDetail newFragment = FragmentDetail.newInstance(id);
setSharedElementReturnTransition(TransitionInflater.from(getActivity()).inflateTransition(R.transition.trans_move));
setExitTransition(TransitionInflater.from(getActivity()).inflateTransition(android.R.transition.explode));
View block = view.findViewById(R.id.blocks);
block.setTransitionName("block");
newFragment.setSharedElementEnterTransition(TransitionInflater.from(getActivity()).inflateTransition(R.transition.trans_move));
newFragment.setEnterTransition(TransitionInflater.from(getActivity()).inflateTransition(android.R.transition.explode));
newFragment.setTransitionId(block.getTransitionName());
FragmentTransaction trans = getFragmentManager().beginTransaction();
trans.replace(R.id.container, newFragment);
trans.addToBackStack(null);
trans.addSharedElement(block, block.getTransitionName());
trans.commit();
This works exactly how I want, but I would like to reverse the effect upon pressing the back button, animating the item back in. As is, the explode animation plays, but the transition does not.
Any help is greatly appreciated.
Thanks
Josh

KOTLIN with Android Navigation Component
For anyone who's here looking for the answer to this question when you're using the Android Navigation component, you can make the reverse transition animation work by adding these lines to the onViewCreated function of the starting fragment:
postponeEnterTransition()
view.doOnPreDraw { startPostponedEnterTransition() }
You would generally use this if you are opening the second fragment by clicking on a RecyclerView item.

Let's say you have two fragments, A and B, and A commits a fragment transaction to start fragment B.
Then that means the exit and reenter transitions should be set on A and the enter and return transitions should be set on B.
It looks like you are calling setSharedElementReturnTransition on the calling fragment instead of the called fragment (newFragment, in this case), which might be causing the problem.
BTW, you should consider calling the set*****Transition() and setSharedElement*****Transition() methods in your fragment's onCreate() method instead of immediately before a fragment transaction is committed. If a fragment is destroyed and recreated, these transitions will be forgotten... so setting them in onCreate() is much safer.

switch from
trans.replace(R.id.container, newFragment);
to
trans.hide(oldFragment).add(R.id.container, newFragment).show(newFragment)
and it should work (as in my case).
reverting a shared fragment transition seems to only work if you hide the old one, instead of replacing it.

I have met the same problem with you.Buy I have found the solution.
You know, there are many causes for this problem. I just show my way.
Hope that can help you.
there are two fragments.
one have a RecyclerView widget:
ListFragment.java
public class ListFragment extends Fragment implements RecyclerItemInter {
#Bind(R.id.recycler_view)
RecyclerView recyclerView;
private OnListItemClickListener onListItemClickListener;
public void setOnListItemClickListener(ListFragment.OnListItemClickListener onListItemClickListener) {
this.onListItemClickListener = onListItemClickListener;
}
public ListFragment() {
}
public static ListFragment newInstance() {
ListFragment fragment = new ListFragment();
return fragment;
}
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
}
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View view = inflater.inflate(R.layout.fragment_list, container, false);
ButterKnife.bind(this, view);
recyclerView.setLayoutManager(new GridLayoutManager(getActivity(), 2));
RecyclerAdapter2 adapter = new RecyclerAdapter2(BEAUTY_BEANS);
recyclerView.setAdapter(adapter);
adapter.setItemInter(this);
return view;
}
private static final BeautyBean[] BEAUTY_BEANS = {
new BeautyBean("Avril Lavigne1", "Avril was born in Canada, the Canadian singer, songwriter creators, actors."),
new BeautyBean("Avril Lavigne2", "Avril was born in Canada, the Canadian singer, songwriter creators, actors."),
new BeautyBean("Avril Lavigne3", "Avril was born in Canada, the Canadian singer, songwriter creators, actors."),
new BeautyBean("Avril Lavigne4", "Avril was born in Canada, the Canadian singer, songwriter creators, actors."),
new BeautyBean("Avril Lavigne5", "Avril was born in Canada, the Canadian singer, songwriter creators, actors.")
};
#Override
public void onDestroyView() {
super.onDestroyView();
ButterKnife.unbind(this);
}
#Override
public void onItemClick(View view, int position) {
}
#Override
public void onIvClick(RecyclerAdapter2.ViewHolder holder, int position) {
OtherFragment otherFragment = OtherFragment.newInstance();
otherFragment.setSharedElementEnterTransition(new CustomTransition());
otherFragment.setSharedElementReturnTransition(new CustomTransition());
/*if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT) {
otherFragment.setEnterTransition(new Fade());
setExitTransition(new Fade());
}*/
getActivity().getSupportFragmentManager()
.beginTransaction()
.replace(R.id.frame_layout, otherFragment)
.addToBackStack(null)
.addSharedElement(holder.getPicIv(), getString(R.string.transition_img))
.commit();
}
then you should set the TransitionName to every ImageView in the RecyclerView:
#Override
public void onBindViewHolder(final ViewHolder holder, final int position) {
if (items[position].getImageId() != 0) {
holder.getPicIv().setImageResource(items[position].getImageId());
}
ViewCompat.setTransitionName(holder.getPicIv(), String.valueOf(position) + "_beauty");
holder.getTitleTv().setText(items[position].getName());
holder.getDescTv().setText(items[position].getDesc());
holder.getLinearLayout().setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
if (null != itemInter) {
itemInter.onItemClick(holder.itemView, position);
}
}
});
holder.getPicIv().setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
if (null != itemInter) {
itemInter.onIvClick(holder, position);
}
}
});
}
click the list jump to the OtherFragment.
OtherFragment.java
public class OtherFragment extends Fragment {
public OtherFragment() {
}
public static OtherFragment newInstance() {
OtherFragment fragment = new OtherFragment();
return fragment;
}
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
}
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
return inflater.inflate(R.layout.fragment_other, container, false);
}
}
fragment_other.xml
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"

app:borderWidth="0dp"
app:elevation="5dp"
app:pressedTranslationZ="10dp"
app:rippleColor="#color/color_gray" />
the crux of the problem is in this xml.
at the beginning, i set the attribute "transitionName" on and its father layout.
Actually we don't need to add the attribute on father Layout.
Just add transitionName to what you want to transform.
OK, that is my solution.

The Joe Muller answer is correct, I wrote it for Java
#Override
public void onViewCreated(#NonNull final View view, #Nullable Bundle savedInstanceState) {
super.onViewCreated(view, savedInstanceState);
postponeEnterTransition();
view.getViewTreeObserver().addOnPreDrawListener(new ViewTreeObserver.OnPreDrawListener() {
#Override
public boolean onPreDraw() {
startPostponedEnterTransition();
view.getViewTreeObserver().removeOnPreDrawListener(this);
return false;
}
});
}
This resolve issue if the start transition is inside an adapter

Keeping List View and View Pager in sync

Forgive me if the title is a little vague, I'm having trouble wording this issue, which is also why I am unable to find any examples via Google.
I'm using the master/detail flow layout in my application as I mostly develop on a tablet.
The implementation follows the usual pattern, two Fragments being contained in one Activity and I have it working perfectly. In this case the detail is actually a ViewPager, with the ViewPager and the ListView being alternate forms of displaying the same data.
So selecting an item in the list will scroll the ViewPager to the position and swiping across will update the selected item in the list.
Here's what I have so far:
MainActivity.java
public class MainActivity extends ActionBarActivity
implements VideoListFragment.Callbacks, VideoDetailFragment.Callbacks {
#Override
public void onItemSelected(String callingClass, int id) {
//Work out which one we're updating based on which class called this method
if (callingClass == VideoListFragment.VIDEO_LIST_ID) {
//Update the VideoDetail
VideoDetailFragment fragment = (VideoDetailFragment) getSupportFragmentManager().findFragmentById(R.id.content_pane);
if (fragment != null) {
fragment.setViewPagerPosition(id);
} else {
Bundle arguments = new Bundle();
arguments.putInt(VideoDetailFragment.VIDEO_ID, id);
fragment = new VideoDetailFragment();
fragment.setArguments(arguments);
getSupportFragmentManager().beginTransaction()
.replace(R.id.content_pane, fragment)
.commit();
}
} else if (callingClass == VideoDetailFragment.VIDEO_DETAIL_ID) {
//Update the VideoList
VideoListFragment fragment = (VideoListFragment) getSupportFragmentManager().findFragmentById(R.id.list_pane);
fragment.setSelection(id);
}
}
}
ListFragment.java
public class ListFragment extends ListFragment {
public interface Callbacks {
public void onItemSelected(String callingClass, int id);
}
#Override
public void onListItemClick(ListView listView, View view, int position, long id) {
super.onListItemClick(listView, view, position, id);
setSelection(position);
mCallbacks.onItemSelected(VIDEO_LIST_ID, position);
}
#Override
public void setSelection(int position) {
mListView.setItemChecked(position, true);
mListView.smoothScrollToPosition(position);
}
}
VideoDetailFragment.java
public class VideoDetailFragment extends Fragment {
public interface Callbacks {
public void onItemSelected(String callingClass, int id);
}
#Override
public void onPageScrolled(int position, float positionOffset, int positionOffsetPixels) {
//Left
if (mListPosition > position + positionOffset) {
mCallbacks.onItemSelected(VIDEO_DETAIL_ID, position);
} else //Right
{
mCallbacks.onItemSelected(VIDEO_DETAIL_ID, position);
}
}
}
It's a pretty basic system but it works for the most part, the only problem is that the system often calls onPageScrolled when the views are being refreshed, such as when new data has downloaded and notifyDatasetChanged is called. This leads to a lot of to and fro-ing with the listview selection flying up and down and looks tacky overall.
A good example of what I want is the GMail app, it has the master detail flow and updates seamlessly. Is there any code examples of this anywhere?
Thanks in advance.

Calling fragment from a list adapter

I am using sliding menu/drawer pattern in my app. So the main activity has a leftView which is a ListFragment named topicsFragment() which loads set of topic items. When an item/topic is clicked it replaces the fragment on main view by calling the FeedsFragment(tag). FeedsFragment uses arraylist adapter to load the feeds which has various clickable items in each list item. I want to fetch another instance on the feedsFragment(tag) when an item is clicked within a list item.
holder.contextView= (TextView) newsView.findViewById(R.id.arcHeader);
if (item.hasArc()) {
holder.contextView.setVisibility(View.VISIBLE);
String arc;
try {
arc=item.getarc();
holder.contextView.setText(arc);
holder.contextView.setOnClickListener(new View.OnClickListener() {
//currently it loads a class
#Override
public void onClick(View v) {
Intent i = new Intent(context, SomeClass.class);
i.putExtra("tag", arc);
context.startActivity(i);
}
});
} catch (JSONException e) {
e.printStackTrace();
}
} else {
holder.contextView.setVisibility(View.GONE);
}
Currently it loads a new class. I want to define a fragment and then pass to main activity to replace with the current view but I cant use getSupportFragmentManager() inside an adapter class but only in a fragment or fragment activity. What should be an alternative to sweeping in a fragment from an adapter?

What I did was create this method in my main activity and just called it from other classes to change the fragment:
public void switchContent(Fragment fragment) {
mContent = fragment;
getSupportFragmentManager().beginTransaction()
.replace(R.id.fragment_container, fragment).commit();
slidemenu.showContent();
}

Solved it by using the context passed in the list adapter:
#Override
public void onClick(View v) {
Fragment newFragment = new ListFragmentClass(tag);
if (newFragment != null)
switchFragment(newFragment);
}
private void switchFragment(Fragment newFragment) {
if (context == null)
return;
if (context instanceof MainActivity) {
MainActivity feeds = (MainActivity) context;
feeds.switchContent(newFragment);
}
}
Here switchContent is method defined in your main activity for switching/replacing fragment as given in answer by Justin V.

Pass getFragmentManager() as a parameter in constructor of your adapter and use that.

Use an Interface to connect your side drawer ListFragment to the main activity. For example:
public class LeftDrawer extends ListFragment{
private DrawerCallback mCallback;
public interface DrawerCallback{
public void onListClick(String tag);
}
public void setCallback(DrawerCallback callback){
mCallback = callback;
}
}
As Fragments should have an empty constructor, use a public method within your Fragment to set the callback before completing the FragmentTransaction adding it to your drawer. At this point all that is left is notifying your Fragment that a click has occurred. What you should do is actually catch the click in your ListFragment directly rather than adding on onClickListener to every view in your adapter.
#Override
public void onListItemClick(ListView l, View v, int position, long id) {
super.onListItemClick(l, v, position, id);
/*
* Get item at the clicked position from your adapter and
* get its string tag before triggering interface
*/
mCallback.onListClick(tag);
}
Use the onListItemClick method to do this. You will get the list position that was clicked and can easily then get that item from your adapter and get its tag value to pass back to your host activity.

Your fragment code is most likely broken and simply crashes on creation which ends in failure of inflation. Plant breakpoints on each fragment onCreateView() and related methods called in during fragment creation or try to instantiate the fragment by hand (new AFragment()) and attaching it to The Layout to see where exactly if fails.

You need to import the Fragment class from android.support.v4.app.Fragment instead of android.app.Fragment.
import android.support.v4.app.Fragment;
And in the XML file of the activity where you intend to use this fragment, you need to use:
<fragment
android:layout_width="match_parent"
android:layout_height="match_parent"
android:id="#+id/map_fragment"
name="yourpackagname.yourfragmentclass"/>
//package name here, is the name of folder which is in java directory.
