Dynamic Tabs with dynamic data in viewpager fragment

I need a help. I am developing dynamic tabs with dynamic data in viewpager fragment's list. Somehow i got the dynamic tabs and hit API in placeholder fragment to get the recyclerview list.
there are two issue. 1. design is overlapping the tabs and 2. its loading 3rd id data first.
here is the code.
here is main class
public class NewsFeed extends Fragment {
private static RecyclerView listView;
private final List<Fragment> mFragmentList = new ArrayList<>();
private final List<String> mFragmentTitleList = new ArrayList<>();
private TabLayout tabLayout;

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.

Step 1: Create Interface
public interface ActivityCommunicator{
public void passDataToActivity(ArrayList<string> arrayList);
}
Step 2:Initialize interface object in fragment class
private ActivityCommunicator activityCommunicator;;
public void onAttach(Activity activity)
{
super.onAttach(activity);
context = getActivity();
activityCommunicator =(ActivityCommunicator)context;
}
#Override
public void onActivityCreated(Bundle savedInstanceState) {
super.onActivityCreated(savedInstanceState);
init();
}
public void init() {
activityButton.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View arg0) {
activityCommunicator.passDataToActivity("Your Array List");
}
});
}
step 3: Access Your arraylist from fragment in your activity class.
public class MainActivity extends FragmentActivity implements ActivityCommunicator{
public static ArrayList<String> aList;
#Override
public void passDataToActivity(ArrayList<String> arrayList){
aList = arrayList;
}
}

Creating a Circle ProgressBar

the one you are showing is a ProgressDialog and one you want to show is a ProgressBar.
you need to include a progressbar in your layout something like this:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent" >
<ProgressBar
android:id="#+id/progressbar"
style="?android:attr/progressBarStyleLarge"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerInParent="true"
android:visibility="gone" />
<LinearLayout
android:layout_width="fill_parent"
android:layout_height="fill_parent" >
<!-- your entire layout here -->
</LinearLayout>
</RelativeLayout>
then you can show or hide the progress bar and/or rest of your layout from java like this:
show:
findViewById(R.id.progressbar).setVisibility(View.VISIBLE);
hide:
findViewById(R.id.progressbar).setVisibility(View.GONE);

FragmentTransaction replace method not replacing a specific fragment

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) {
}

}
});
}

Edit: Included the 3rd fragment's layout

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.
