android - Fragment onCreateView not called after update and commiting transaction - android

I am unable to get a fragment to update after changing data. I call
getFragmentManager().beginTransaction().detach(this).attach(this).commit();
but onCreateView does not get called. I tried several different ways in refreshFragment(). I do see messages for "I/InjectionManager: dispatchCreateOptionsMenu" after I put in the above line of code so something is happening, but onCreateView() is not getting called.
public class MainActivityFragment extends Fragment {
private static Logger logger = Logger.getLogger(MainActivityFragment.class);
String poolWord = "ABCDE";
String newWord = "";
public MainActivityFragment() {
}
#Override
public void onCreate(Bundle savedInstanceState) {
logger.info("onCreate------------------------");
super.onCreate(savedInstanceState);
setHasOptionsMenu(true);
}
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
logger.info("onCreateView------------------------");
// Inflate the layout for this fragment
View view = inflater.inflate(R.layout.fragment_main, container, false);
GridView gridViewPool = (GridView) view.findViewById(R.id.gridviewPool);
gridViewPool.setAdapter(new LetterImageAdapter(getActivity(), poolWord));
gridViewPool.setOnItemClickListener(new AdapterView.OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
logger.error("po " + position);
updateWords(position);
refreshFragment();
}
});
GridView gridviewNewWord = (GridView) view.findViewById(R.id.gridviewNewWord);
gridviewNewWord.setAdapter(new LetterImageAdapter(getActivity(), ""));
return view;
}
private void refreshFragment() {
logger.info("refreshFragment------------------------");
getFragmentManager().beginTransaction().detach(this).attach(this).commit();
// getFragmentManager().beginTransaction().replace(R.id.fragment, this).attach(this).commit();
// Fragment fragment = getFragmentManager().findFragmentById(R.id.fragment);
//getFragmentManager().beginTransaction().detach(fragment).attach(fragment).commit();
getFragmentManager().executePendingTransactions();
}

After several hours, I got it to work. Not sure of all the details as this is my first android project. Posting an answer in case anybody else has the same problem.
The crux of the problem, I suspect, is the generated code from Intellij did not start a transaction in the Activity class. It did not include
if (savedInstanceState == null) {
getSupportFragmentManager().beginTransaction()
.add(R.id.container, new MainActivityFragment())
.commit();
}
I'm not sure how my MainActivityFragment was created without this, but it was.I also replaced the generated activity-main.xml with one I had from a tutorial. The one from Intellij did not have an android:id that I could use for the container object. It also contained other stuff I did not need at this time.The new activity-main.xml looks like this:
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools" android:id="#+id/container"
android:layout_width="match_parent" android:layout_height="match_parent"
tools:context=".MainActivity" tools:ignore="MergeRootFrame"/>
The old generated one was:
<android.support.design.widget.AppBarLayout
android:layout_height="wrap_content"
android:layout_width="match_parent"
android:theme="#style/AppTheme.AppBarOverlay">
<android.support.v7.widget.Toolbar
android:id="#+id/toolbar"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
android:background="?attr/colorPrimary"
app:popupTheme="#style/AppTheme.PopupOverlay"/>
</android.support.design.widget.AppBarLayout>
<include layout="#layout/content_main"/>
</android.support.design.widget.CoordinatorLayout>
There was also a content-main.xml which I got rid of. That may be what android used to generate my MainActivityFragment without explicit code. Someone more experienced with android development may be able to answer that.
<fragment xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:id="#+id/fragment"
android:name="com.ultramondo.mywordandroid.MainActivityFragment"
android:layout_width="match_parent"
android:layout_height="match_parent"
app:layout_behavior="#string/appbar_scrolling_view_behavior"
tools:layout="#layout/fragment_main">
</fragment>
I'm sure there's some useful stuff I can go back to but for now I want simplicity. I also had to make some changes to use android.support.v4.app packages for Fragment and Transaction classes. It's kind of like coming in the middle of a movie and figuring out what the plot is. Once I see the whole movie, I'm sure it will become clearer.

Android views in fragments overlapping

So I've read several tutorials and many of the posts on SO but I still can't get this to work. I'm trying to use dynamically added fragments but when loading a fragment TextViews and ImageViews in the fragment keep overlapping instead of updating their values, like so:
and fragments overlap each other when replaced.
I got a main activity (extending AppCompatActivity) split into 2 layouts:
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:id="#+id/root_layout"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#color/background_white"
android:orientation="vertical"
tools:context=".MainActivity">
<FrameLayout
android:id="#+id/upperFrameLayout"
android:layout_width="match_parent"
android:layout_height="0dp"
android:layout_weight="1" />
<androidx.constraintlayout.widget.ConstraintLayout
android:id="#+id/lowerLayout"
android:layout_width="match_parent"
android:layout_height="wrap_content">
...
The upper FrameLayout contains my fragments. The fragments are replaced in this method in the MainActivity-class:
void setMode() {
// Show "find opponent"- or "fight"-fragment
FragmentTransaction fragmentTransaction = getSupportFragmentManager().beginTransaction();
if (!debugFight && (btCoordinator == null || !btCoordinator.isConnected())) {
fragmentTransaction.replace(R.id.upperFrameLayout, new FindOpponentFragment());
} else {
fragmentTransaction.replace(R.id.upperFrameLayout, new FightFragment());
}
fragmentTransaction.commitNow();
}
What am I missing?
EDIT: Added FightFragment onCreateView()-method:
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
((TextView) inflater.inflate(R.layout.fragment_fight, container, false).findViewById(R.id.score_textView)).setText(getString(R.string.score, 0, 0));
((TextView) inflater.inflate(R.layout.fragment_fight, container, false).findViewById(R.id.opponent_textView)).setText(MainActivity.opponentName.toUpperCase());
final AnimatedVectorDrawableCompat animated = AnimatedVectorDrawableCompat.create(container.getContext(), R.drawable.loading_animated_vector);
animated.registerAnimationCallback(new Animatable2Compat.AnimationCallback() {
#Override
public void onAnimationEnd(Drawable drawable) {
animated.start();
}
});
((ImageView) inflater.inflate(R.layout.fragment_fight, container, false).findViewById(R.id.opponent_hand_imageview)).setImageDrawable(animated);
animated.start();
// Inflate the layout for this fragment
return inflater.inflate(R.layout.fragment_fight, container, false);
}
...and as I pasted this piece of code I just realised that those inflated views are all different objects. I replaced them with a single object which I modify and then let the method return and it works. I guess I have to read up on views and the inflate-method.
use fragmentTransaction. add() instead of replace()
Use this above the fragment commit
fragmentTransaction.addToBackStack(null);
I didn't understand how the inflate-method. I modified my fragments onCreateView-method as seen in the OP and now it works.

How to organize architecture of displaying two different Fragments in activity?

I have some sort of architecture issue:
I have Activity in which I need to show one of 3 views (one view at one moment in time):
1. One view with stable AppBarLayout + another part of the screen is
NestedScrollView that needs to be in separate fragment.
2. One view with stable AppBarLayout + another part of screen need to be a fragment with two tabs to switch between them.
3. Connection lost view - is a fullscreen view without AppBar - just to show that there is no connection.
The upper part of AppBarLayout - I made. Looks like good, but I need runtime to switch Fragments depending on the response from Server.
I am sending a request to the server in onCreate method in MainActivity, and then in onDataLoadedFromServer callback, depending on response - I am deciding which fragment to create. But my application crashes, because fragments fields are not initialized properly - the view is not attached to fragment. When I am adding fragment in onCreate method - everything is working good, but at that time I don't have a response from server.
Where to place TabLayout? And where ViewPager? Do I need to put
TabLayout in main_activity.xml, and ViewPager in separate
fragment_2_layout. And then add it to FrameLayout (container for
fragment which is located in main_activity)?
Is it good practice to load some data from the server in the fragment? Or it's better to load data in Activity and then set it through the method
call to Fragment?
Please, provide some sort of pseudo code to understand logic. Thanks!.

FragmentTransaction.remove() not removing fragment only while SwipeRefreshLayout is active

The gist of my problem:
I have multiple fragments that are added sequentially and not re-ordered. Almost all of them have SwipeRefreshLayouts as their root views. When the user triggers onBackPressed, the last fragment should be removed. If a new fragment is opened, the last fragment is hidden.
In the event that the SwipeRefreshLayout is active (ie refresh state set to true and onRefresh is called) and the user pops off the current fragment, the view remains stuck until an app restart. I've confirmed that onPause() and onDestroy() do get called. I have tested this across each type of my fragments, so I'm nearly sure the problem lies in how I remove fragments.
My code:
//I know this is a misnomer. I just changed the inside from
//addToBackStack which got me the same effect
protected void addToBackStack(BaseFragment fragment){
FragmentTransaction ft = fragMan.beginTransaction();
if(fragCount > 0)
ft.hide(peekBackStack());
ft.add(R.id.fragment_container, fragment, Integer.toString(fragCount++)).commit();
invalidateOptionsMenu();
}
protected BaseFragment peekBackStack(){
return (BaseFragment)(fragMan.findFragmentByTag(Integer.toString(fragCount - 1)));
}
#Override
public void onBackPressed(){
if (fragCount <= 1) {
//...do stuff & finish
} else {
BaseFragment fragment = peekBackStack();
if(fragment != null) {
if (fragment.isWeb() && ((WebFragment) fragment).canGoBack())
((WebFragment) fragment).goBack();
else
popActive();
}
else
finish();
}
}
public void popActive(){
BaseFragment remove = peekBackStack();
fragCount--;
BaseFragment show = peekBackStack();
fragMan.beginTransaction().remove(remove).commit();
Log.d(TAG, ""+remove.isVisible());
fragMan.beginTransaction().show(show).commitNow();
show.initAppBar();
}
Inside BaseFragment.java
#Override
#NonNull
public View onCreateView(#NonNull LayoutInflater inflater, #Nullable ViewGroup container,
#Nullable Bundle state){
ViewGroup root = (ViewGroup) inflater.inflate(getLayoutResource(), container, false);
if(root instanceof SwipeRefreshLayout) {
swipeRefreshLayout = (SwipeRefreshLayout) root;
swipeRefreshLayout.setOnRefreshListener(this);
}
return root;
}
#Override
public void onDestroy(){
super.onDestroy();
if(swipeRefreshLayout != null)

So I found a related thread after hours of searching. Both solutions worked for me, although I think I prefer the FrameLayout wrapper for now. This seems to be a bug in android itself

having a condition to fragment adding

for the last 4 hours ive been trying to understand how to do it.
to be clear, i need to add a fragment under a certain condition and for my purpose the condition can be either:
a. if the parent's id matches to what i seek.
b. if the fragment's id matches to what i seek.
i tried to put the condition inside the fragment itself:
public class BlockFrag extends Fragment{
SharedPreferences sp;
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState)
{
sp = getActivity().getSharedPreferences("myOptions", Context.MODE_PRIVATE);
int id = container.getId();//didn't work(i think the container is null for some reason
switch (id)
{
default: return inflater.inflate(R.layout.nothing, container, false);
case (R.id.redFrame): {
if (sp.getBoolean("redBlock", true)) {
return inflater.inflate(R.layout.block_frag, container, false);
}
}
case (R.id.greenFrame): {
if (sp.getBoolean("greenBlock", true)) {
return inflater.inflate(R.layout.block_frag, container, false);
}
i also tried to get the condition programatically but i cant understand how to prevent the fragment to automatically generate when i call the layout it's placed.
this is the layout it's placed for example
<FrameLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:id="#+id/redFrame"
android:layout_weight="0.33333">
<fragment
android:name="com.example.dor.myapplication.BlockFrag"
android:id="#+id/blockRed"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:layout="#layout/block_frag"/>
this is the fragment's layout if it matters...
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_alignParentLeft="true"
android:layout_alignParentStart="true">
<ImageView
android:layout_width="118dp"
android:layout_height="match_parent"
android:id="#+id/blockFrag"
android:src="#drawable/block"
android:layout_weight="0.33333"
android:layout_above="#+id/linearLayout"
android:layout_alignParentLeft="true"
android:layout_alignParentStart="true"
android:layout_gravity="left"
android:scaleType="fitXY"/>
thank you for helping, any kind of way to do this will help me.
I did something similar earlier, I had to decide based on a value from PickHeaderFragment which Fragment to show inside my root_frame_body, here's how I achieved it:
My Parent or Host Fragment:
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="match_parent"
android:layout_height="match_parent">
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:background="#000"
android:layout_height="wrap_content"
android:id="#+id/root_frame_header" />
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:background="#000"
android:layout_weight="1"
android:layout_height="match_parent"
android:id="#+id/root_frame_body" />
</LinearLayout>
Inside my Host Fragment:
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
View rootView = inflater.inflate(R.layout.fragment_pick, container, false);
headerFragment = PickHeaderFragment.newInstance("");
getChildFragmentManager().beginTransaction().replace(R.id.root_frame_header, headerFragment).commit();
}
My PickHeaderFragment has an OnPickHeaderFragmentInteractionListener Interface implemented which looks like this:
public interface OnPickHeaderFragmentInteractionListener {
public void onFragmentInteraction(int res);
}
I ensure my Host Fragment will implement this interface by adding it during onAttach (inside PickHeaderFragment) like so:
#Override
public void onAttach(Activity activity) {
super.onAttach(activity);
try {
Fragment f = getParentFragment();
mListener = (OnPickHeaderFragmentInteractionListener) getParentFragment();
} catch (ClassCastException e) {
throw new ClassCastException(activity.toString() + " must implement OnFragmentInteractionListener");
}
}
Now, when the enter Button inside my PickHeaderFragment is clicked I call this event to let my Host Fragment know to change the root_frame_body:
Inside my Host Fragment I have:
#Override
public void onFragmentInteraction(int res) {
if (res == R.id.btnEnter) {
getChildFragmentManager().beginTransaction().replace(R.id.root_frame_body, new PickByItemBodyFragment()).commit();;
}
}
I am now able to change the layout (or which Fragment is displayed) in my Host Fragment after an event occurs inside a child Fragment.
Note: In my example I have nested Fragments, but you could just as easily have several Fragments within an Activity.
In summary I would recommend you follow a similar pattern of having a host Activity or Fragment and ensuring you have a FrameLayout added to your view to allow you to inflate whatever Fragment you need.
An added benefit to doing it this way is that you can segregate your code into separate Fragments also.
Leigh thank you for your answer but i don't know if you didn't understand my question or i didn't understand your answer...
anyway, i solved my problem through programatically adding the fragment in r=the onCreate of the activity and inserting the adding to an "if"
BlockFrag rb = new BlockFrag();
FragmentManager fragmentManager = getFragmentManager ();//declaring Fragment Manager
FragmentTransaction fragmentTransaction = fragmentManager.beginTransaction ();// declaring Fragment Transaction
if(condition)
{
editor.putBoolean("redBlock", true);
fragmentTransaction.add(R.id.redFrame, rb);//adding the fragment
}
needless to say i didn't declare the fragment in my activity layout and didn't perform any changes in the fragment class or fragment xml layout.

When switch fragment with SwipeRefreshLayout during refreshing, fragment freezes but actually still work

UPDATE: I thought it worked correctly. But after some test trouble still exists *sniff*
Then I made a simpler version to see what exactly happen and I get to know that the refreshing fragment which should have been detached still left there. Or exactly, the view of the old fragment left there, on top of the newer fragment. Since RecyclerView's background of my original app is not transparent, so It turned out what I said before.
END OF UPDATE
I have a MainActivity with layout like this:
<android.support.v4.widget.DrawerLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools" android:id="#+id/drawer_layout"
android:layout_width="match_parent" android:layout_height="match_parent">
<!-- As the main content view, the view below consumes the entire
space available using match_parent in both dimensions. -->
<FrameLayout android:id="#+id/container" android:layout_width="match_parent"
android:layout_height="match_parent" />
<!-- android:layout_gravity="start" tells DrawerLayout to treat
this as a sliding drawer on the left side for left-to-right
languages and on the right side for right-to-left languages.
If you're not building against API 17 or higher, use
android:layout_gravity="left" instead. -->
<!-- The drawer is given a fixed width in dp and extends the full height of
the container. -->
<fragment android:id="#+id/navigation_drawer"
android:layout_width="#dimen/navigation_drawer_width" android:layout_height="match_parent"
android:layout_gravity="start" tools:layout="#layout/fragment_navigation_drawer" />
</android.support.v4.widget.DrawerLayout>
The fragment ContentView I use to fill #id/container is configured as:
<android.support.v4.widget.SwipeRefreshLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/contentView"
android:layout_width="match_parent"
android:layout_height="match_parent">
<android.support.v7.widget.RecyclerView
android:id="#+id/tweet_list"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#color/grey_300"/>
</android.support.v4.widget.SwipeRefreshLayout>
And here is onCreateView() of ContentView
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
// Inflate the layout for this fragment
View inflatedView = inflater.inflate(R.layout.fragment_content, container, false);
mRecyclerView = (RecyclerView) inflatedView.findViewById(R.id.tweet_list);
mRecyclerView.setHasFixedSize(false);
mLinearLayoutManager = new LinearLayoutManager(getActivity().getApplicationContext());
mRecyclerView.setLayoutManager(mLinearLayoutManager);
mTweetList = new ArrayList<Tweet>;
mAdapter = new TweetAdapter(mTweetList);
mRecyclerView.setAdapter(mAdapter);
mRecyclerView.setItemAnimator(new DefaultItemAnimator());
mSwipeRefreshLayout = (SwipeRefreshLayout) inflatedView.findViewById(R.id.contentView);
mSwipeRefreshLayout.setOnRefreshListener(
...
);
return inflatedView;
}
Then in MainActivity I switch the content to display by switching different ContentView. All looks good except one thing: when I switch ContentView fragments DURING refreshing by navigation drawer, then content freezes. But actually all things work as usual except you cannot see it.
Well... After some struggling I eventually solved this problem by myself, in a tricky way...
I just need to add these in onPause() :
#Override
public void onPause() {
super.onPause();
...
if (mSwipeRefreshLayout!=null) {
mSwipeRefreshLayout.setRefreshing(false);
mSwipeRefreshLayout.destroyDrawingCache();
mSwipeRefreshLayout.clearAnimation();
}
}
This issue seems to still be occurring in appcompat 22.1.1. Wrapping the SwipeRefreshLayout inside a FrameLayout solved this for me
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent">
<android.support.v4.widget.SwipeRefreshLayout
android:id="#+id/contentView"
android:layout_width="match_parent"
android:layout_height="match_parent">
<android.support.v7.widget.RecyclerView
android:id="#+id/tweet_list"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#color/grey_300" />
</android.support.v4.widget.SwipeRefreshLayout>
</FrameLayout>
In addition to #zlm2012 answer, I noticed that this issue was reproduced under Support Library 21.0.0, but seems to be fixed right now at 21.0.3
The solution works, but I think it is better just put those lines into its own function, like:
public void terminateRefreshing() {
mSwipeRefreshLayout.setRefreshing(false);
mSwipeRefreshLayout.destroyDrawingCache();
mSwipeRefreshLayout.clearAnimation();
}
and call when switching the fragment.
Fragment prevFrag = fragmentManager.findFragmentById(drawerContainerId);
if(prevFrag instanceof SwipeRefreshFragment) {
((SwipeRefreshFragment)prevFrag).terminateRefreshing();
}
fragmentManager.beginTransaction().replace(drawerContainerId, fragment).commit();
It works! Just remove the transition from your fragment replacement, in my case I removed the following from my code:
.setTransition(FragmentTransaction.TRANSIT_FRAGMENT_OPEN)
Set clickable="true" in top parent layout... It may solve the problem.
For the time being, you can avoid the issue by:
public class FixedRefreshLayout extends SwipeRefreshLayout {
private static final String TAG = "RefreshTag";
private boolean selfCancelled = false;
public FixedRefreshLayout(Context context) {
super(context);
}
public FixedRefreshLayout(Context context, AttributeSet attrs) {
super(context, attrs);
}
#Override
protected Parcelable onSaveInstanceState()
{
if(isRefreshing()) {
clearAnimation();
setRefreshing(false);
selfCancelled = true;
Log.d(TAG, "For hide refreshing");
}
return super.onSaveInstanceState();
}
#Override
public void setRefreshing(boolean refreshing) {
super.setRefreshing(refreshing);
selfCancelled = false;
}
#Override
public void onWindowFocusChanged(boolean hasWindowFocus) {
super.onWindowFocusChanged(hasWindowFocus);
if(hasWindowFocus && selfCancelled) {
setRefreshing(true);
Log.d(TAG, "Force show refreshing");
}
}
}
This has the added advantage of resuming the animation incase you decide to not switch the fragment (coming from some menu). It also ties in with the internal animation to make sure that the refreshing animation does not return if the network refresh has already completed.
Terminate SwipeRefresh whenever navigation menu item is clicked.
It worked.
private void selectItem(int position) {
mSwipeRefreshLayout.setRefreshing(false);
/*
Other part of the function
*/
}
