FragmentTransaction replace method not replacing a specific fragment

FragmentTransaction replace method not replacing a specific fragment - android

I am using TabLayout to show three tabs and on selection of each am calling FragmentTransaction.replace method. Now my problem is that the first two fragments are correctly replaced but the third fragment in particular is not getting replaced though I debugged and found that all corresponding methods of the 3rd fragments are called and there is no error. Now am out of my wits, please help!!.
This is the code in my onCreate() method of my main activity from where i am showing the three tabs.
TabLayout tabLayout = (TabLayout) findViewById(R.id.tab_layout);
tabLayout.addTab(tabLayout.newTab().setText("Home"));
tabLayout.addTab(tabLayout.newTab().setText("Explore"));
tabLayout.addTab(tabLayout.newTab().setText("Me"));
tabLayout.setTabGravity(TabLayout.GRAVITY_FILL);
final FragmentTransaction transaction = getSupportFragmentManager().beginTransaction();
HomeTabFragment htf = new HomeTabFragment();
transaction.replace(R.id.tab_content_fragment, htf);
transaction.commit();
tabLayout.setOnTabSelectedListener(new TabLayout.OnTabSelectedListener() {
#Override
public void onTabSelected(TabLayout.Tab tab) {
int position = tab.getPosition();
if (position == 0) {
FragmentTransaction transaction = getSupportFragmentManager().beginTransaction();
HomeTabFragment htf = new HomeTabFragment();
transaction.replace(R.id.tab_content_fragment, htf);
//transaction.commitAllowingStateLoss();
transaction.addToBackStack(null);
transaction.commit();
} else if (position == 1) {
FragmentTransaction transaction = getSupportFragmentManager().beginTransaction();
ItemListFragment ilf = new ItemListFragment();
transaction.replace(R.id.tab_content_fragment, ilf);
//transaction.commitAllowingStateLoss();
transaction.addToBackStack(null);
transaction.commit();
} else if (position == 2) {
FragmentTransaction transaction = getSupportFragmentManager().beginTransaction();
MeTabFragment meTabFragment = new MeTabFragment();
transaction.replace(R.id.tab_content_fragment, meTabFragment);
transaction.addToBackStack(null);
transaction.commit();
//transaction.commitAllowingStateLoss();
}
}
#Override
public void onTabUnselected(TabLayout.Tab tab) {
}
#Override
public void onTabReselected(TabLayout.Tab tab) {
}
});
}
And this is my MeTabFragment...

Edit: Included the 3rd fragment's layout

</LinearLayout>

Since your code is identical for every fragment look for the reason in the third fragment's layout.
First of all change root ScrollView parameters like this:
<ScrollView xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/scroll_container"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:fillViewport="true" >
I suppose original android:layout_height="0dp" isn't processed as you expect, so fragment is actually inflated and added but you just don't see it.

out of memory exception with glide and ViewPager

I have a gallery of images that shows the images in a recyclerviewusing glide and by clicking on each image in the recyclerview that image open in a view pager. every thing is ok in the beginning the recyclerview is fine, the images open in a viewpager and sliding in viewpager are all fine. but when i press back to close the viewpager and goback to recyclerview suddenly the allocated memory raises to about 400 MB!!!
there are 8 images that are about 490*420 pixel and 72 KB size.

I have written setHasOptionsMenu(true); in onCreate of UserFragment.java
The logout functionality works fine but the search isn't working.
I have tried various options given on Stackoverflow as well as from other resource, but nothing worked. :(
Any help is appreciated.
Thanks in advance.

Create Constructor in your fragment. Pass Context object inside fragment constructor.which allows your activity as global access.

Remove this line and it will work

How to update fragment's data used in ViewPager? View is not showing the updated data

I know the same question has been asked so many times but I am not able to solve my issue.
I have created an Activity which has a ViewPager which should have 4 Pages.
I am using the same Fragment for all pages. The Fragment has a GridView which should be updated whenever I swipe to the other page.
Following are the classes & XML layouts I have used to create it.
Activity layout activity_discover.xml
<android.support.v4.view.ViewPager
android:id="#+id/activity_discover_view_pager"
android:layout_width="match_parent"
android:layout_height="wrap_content"

<android.support.v4.view.PagerTabStrip
android:id="#+id/activity_discover_pager_tab_strip"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="#color/white"
android:textColor="#color/black"
android:textSize="#dimen/header_text" />

android:verticalSpacing="5dip" />
</LinearLayout>
On page swipe (or it could be any other event) I hit an API which gives me some data that I have to update in the corresponding Fragment.
Whenever I get the data from server I call the prepareMediaList method which calls the updateData method of Fragment. I can see in logs that there is data in list but that data is not shown in the Fragment's GridView (not even in TextView).
I am really not getting what is wrong in this.
Now it has become very frustrating, looks so simple but still couldn't find any solution.
Edit
I just tried with one Fragment only & it is working properly. So there is something which has to do with multiples.
Edit 2
I couldn't find the solution for this so I had to switch to alternate way. I removed the Fragments from ViewPager instead I added static views to it. In my case I added four GridViews to ViewPager. This was simple & bit complex but most important thing is, it is working the way I wanted.
But still I am looking for the answer.

After checking your code more in details i see you do not require to re-initliaze your MediaAdapter inside updateData method.
You simply require to update your updateData as
listMedia.clear();
this.listMedia.addAll(listMedia);
mediaAdapter.notifyDatasetChanged();
This will reload your data in gridview. Change i suggested will refresh the data in your arraylist which is being used for rendering gridview and then you notify your mediaAdapter to reload the list.

How to show expandable list navigation instead of horizontal navigation?

I am currently using normal horizontal navigation in my code such that when you click on the button, it will navigate to a new fragment horizontally. I want to make it such that instead of calling a new fragment it just expands /collapses upon clicking/clicking again. The code I have so far is :
Here is the activity:
public class ManageNewsCategoriesActivity extends AbsBaseDoubleButtonActivity {
private List<AdapterRow> mBreakingViews;
public HashSet<CategoryCheckableRow> mCategoriesMap = new HashSet<CategoryCheckableRow>();
private int mTitleId = R.string.title_manage;
public static void newInstance(final Activity activity) {
final Intent intent = new Intent(activity.getApplicationContext(), ManageNewsCategoriesActivity.class);
activity.startActivity(intent);
}
#Override
protected void onCreate(final Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_manage_news_categories);
overridePendingTransition(R.anim.slide_in_from_bottom, R.anim.no_animation);
mActiveFragment = ManageNewsCategoriesFragment.newInstance(getSupportFragmentManager(), 0);
}
public void animateTitle(final int textViewId) {
animateTitle(textViewId, R.anim.slide_in_from_right);
}
public void animateTitle(final int textViewId, final int animationId) {
final TextView titleView = (TextView) findViewById(textViewId);
final Animation animation = AnimationUtils.loadAnimation(this, animationId);
titleView.startAnimation(animation);
}
public void setBreakingViews(final List<AdapterRow> categoryRows) {
mBreakingViews = categoryRows;
}
public List<CategoryCheckableRow> getBreakingViews() {
return removeHeaders(mBreakingViews);
}
public List<AdapterRow> getBreakingViewsCategoryRows() {
if (mBreakingViews == null) {
return null;
}
return AbsBaseManageNewsFragment.getAClone(mBreakingViews);
}
private List<CategoryCheckableRow> removeHeaders(final List<AdapterRow> mCategoryRows) {
final List<CategoryCheckableRow> items = new ArrayList<CategoryCheckableRow>();
if (mCategoryRows != null) {
for (final AdapterRow row : mCategoryRows) {
if (row instanceof CategoryCheckableRow) {
final CategoryCheckableRow item = (CategoryCheckableRow) row;
items.add(item);
}
}
}
return items;
}
public boolean isDoneButtonEnabled() {
return !mCategoriesMap.isEmpty();
}
public void updateCategoriesMap(final HashSet<CategoryCheckableRow> categoryRows) {
for (final CategoryCheckableRow row : categoryRows) {
if (!mCategoriesMap.add(row)) {
mCategoriesMap.remove(row);
}
}
}
#Override
protected int getTitleId() {
return mTitleId;
}
#Override
public void updateTitleId(final int titleId) {
mTitleId = titleId;
updateTitleId();
}
Here is the fragment:
public class ManageNewsCategoriesFragment extends Fragment implements OnClickListener,OnCheckedChangeListener {

return fragment;
}

}

}
private void initManageNewsCategoriesFragment() {
setupClickListeners();
final Button breakingViewsButton = (Button) getView().findViewById(R.id.button_breakingviews);
breakingViewsButton.setOnClickListener(this);
}
#Override
public void onClick(final View view) {
final ManageNewsCategoriesActivity activity = (ManageNewsCategoriesActivity) getActivity();
switch (view.getId()) {
case R.id.button_breakingviews:
ManageBreakingViewsFragment.newInstance(getFragmentManager());
return;
case R.id.button_done:

break;
default:
break;
}

}
private void syncNewsCategories(final ManageNewsCategoriesActivity activity) {

if ( ArrayUtils.isNotEmpty(breakingViews)) {
RestService.start(activity, new UserCategoriesSyncOperation(NewsContentProvider.USER_CATEGORIES_URI, breakingViews));
}
}
}
Here is the corresponding xml:
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#color/altercolor2" >

android:layout_centerVertical="true"
android:paddingRight="17.5dp"
android:paddingTop="0dp"
android:src="#drawable/arrow_chevron_selector" />
</RelativeLayout>
</LinearLayout>
</FrameLayout>
Any clue how to go about the same? Please explain programmatically and with respect to my code to avoid confusion.
Thanks!

I think what you want is a custom expandable list view. Here is a very good tutorial on it: ExpandableListView
