I am working with recyclerview with viewpager in fragment.
I want to make navigation on bottom of screen.
enter image description here
and when I click each button, each fragment show in the frameLayout.
the problem is happen when I enter into the artist fragment second time.(at first time it show up find as I intended.)
as you can see in this image enter image description here
there is noting shows up in the fragment. and swiping the screen not working properly. It should moving stick to the left or right but it stop at the point where I stop moving my finger.
here is my source.

It's hard to tell exactly due to the navigational structure of your app, but think the solution to your problem is to use the childFragmentManager inside of the ArtistBoardFragment. i.e, instead of
pageAdapter = new FragmentPagerAdapter(getActivity().getSupportFragmentManager()) ...
Use
pageAdapter = new FragmentPagerAdapter(getChildFragmentManager()) ...

First, my app is like this.

It's silly but in your fragment_space_edit_item.xml
<ImageView
android:id="#+id/myItemImg"
android:layout_width="50dp"

android:layout_marginTop="5dp"

background and contentDescription are Error if that is the case.
I am trying to use Fragment

}
private void initEvent() {

mLLAbout.setOnClickListener(this);
mViewPager.setOnPageChangeListener(new ViewPager.OnPageChangeListener() {//ViewPager Scrolling Switch Listner
#Override
public void onPageSelected(int arg0) {

resetImag();
switch (currentItem) {
case 0:
mImageViewHome.setImageResource(R.drawable.home_yes);
break;

}
private void initView() {
mViewPager = (ViewPager) findViewById(R.id.viewpager);
mLLHome = (LinearLayout) findViewById(R.id.ll_home);
mLLTimer = (LinearLayout) findViewById(R.id.ll_timer);

}
The ViewPagerFragmentAdapter Looks like this:
public class ViewPagerFragmentAdapter extends FragmentStatePagerAdapter {
private List<Fragment> datas;
public ViewPagerFragmentAdapter(FragmentManager fm,List<Fragment> datas) {
super(fm);
this.datas=datas;
}
#Override
public Fragment getItem(int position) {// Return View Object
return datas.get(position);
}
#Override
public int getCount() {// Return View Num
return datas.size();
}
#Override
public Object instantiateItem(ViewGroup container, int position) {// Init View
return super.instantiateItem(container, position);
}
#Override
public void destroyItem(ViewGroup container, int position, Object object) {// Destroy View
super.destroyItem(container, position, object);
}
}

And This is one of the fragment:
public class MyFragment1 extends Fragment {
#Nullable
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
return inflater.inflate(R.layout.tab1,null);
}
}
I have four fragment prepared for viewpager(they are basiclly the same but with differnt layout), here is what the tab1 layout might look like:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:gravity="center"
android:orientation="vertical" >
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center"
android:text="Chat"
android:textSize="30sp" >
</TextView>
</LinearLayout>
And I only got the menu bar when I run it, the viewpager is not set and I don't know why
Remove android:layout_weight="1" <Viewpager> and add android:orientation="vertical" to Linear layout
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:orientation="vertical"
android:layout_height="match_parent">

Ok, all codes here.iam new in android . so i dont know whtais the problrm here. some time fragment and activity contents are mixing..
the problems are only in xml file.not in programattic code
Try this code..
set both fragment background color into root attribute it means Relative layout tag.
android:background="#android:color/white"
and card view refer this link it give good demo for that..
https://www.androidhive.info/2016/05/android-working-with-card-view-and-recycler-view/
add fragment into activity then call onCreate method in below code..
Fragment fragment = new MainFragment();
getSupportFragmentManager().beginTransaction()
.replace(R.id.fragment_frame, fragment, fragment.getClass().getSimpleName()).addToBackStack(null).commit();
So I know this has been answered multiple times, such as Fragment Inside Fragment. I am using the support library for getChildFragmentManager() as advised in the post. The issue is that my viewpager's fragments are not appearing despite being inflated. My tabs (with icons) are showing perfectly fine. Here is the relevant code:
DialogFragment:
public class DialogFragment extends DialogFragment {
private static final String ARG_PAGE = "ARG_PAGE";
private int mPage;
private HotSpot hotSpot;
private Gson gson = new Gson();
private Map nonEmptyPerks;
private TabLayout tabLayout;
private ViewPager viewPager;
public DialogFragment() {
// Empty constructor required for DialogFragment
}
public static PerkDetailDialogFragment newInstance(int page, String hotSpotJson) {
Bundle args = new Bundle();
args.putInt(ARG_PAGE, page);
args.putString("HOTSPOTDETAILED", hotSpotJson);
PerkDetailDialogFragment fragment = new PerkDetailDialogFragment();
fragment.setArguments(args);
return fragment;
}
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
mPage = getArguments().getInt(ARG_PAGE);
String json = getArguments().getString("HOTSPOTDETAILED");
hotSpot = gson.fromJson(json, HotSpot.class);
}
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup parent, Bundle savedInstanceState) {
View view = inflater.inflate(R.layout.fragment_dialog, parent, false);
// Get the ViewPager and set it's PagerAdapter so that it can display items
viewPager = (ViewPager) view.findViewById(R.id.viewpager);
tabLayout = (TabLayout) view.findViewById(R.id.perkSelector);
return view;
}
#Override
public void onViewCreated(View view, Bundle savedInstanceState) {
nonEmptyPerks = getNonEmptyPerks(hotSpot.getPerks());
PerkFragmentPagerAdapter pagerAdapter =
new PerkFragmentPagerAdapter(getChildFragmentManager(), nonEmptyPerks.size());
viewPager.setAdapter(pagerAdapter);
// Give the TabLayout the ViewPager
tabLayout.setupWithViewPager(viewPager);
// ..... More code here
}
#Override
public void onStart() {
super.onStart();
getDialog().getWindow().setLayout(
RelativeLayout.LayoutParams.MATCH_PARENT, RelativeLayout.LayoutParams.MATCH_PARENT);
}
public class PerkFragmentPagerAdapter extends FragmentPagerAdapter {
private int pageCount;
public PerkFragmentPagerAdapter(FragmentManager fm, int pageCount) {
super(fm);
this.pageCount = pageCount;
}
#Override
public int getCount() {
return pageCount;
}
#Override
public Fragment getItem(int position) {
String perk = "temp";
return PerkFragment.newInstance(position + 1, perk);
}
}
}
PerkFragment:
public class PerkFragment extends Fragment {
private static final String ARG_PAGE = "ARG_PAGE";
private static final String ARG_PERK_DESCRIPTION = "PERK_DESCRIPTION";
private int mPage;
private String perkDescription;
public static PerkFragment newInstance(int page, String perk) {
Bundle args = new Bundle();
args.putInt(ARG_PAGE, page);
args.putString(ARG_PERK_DESCRIPTION, perk);
PerkFragment fragment = new PerkFragment();
fragment.setArguments(args);
return fragment;
}
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
mPage = getArguments().getInt(ARG_PAGE);
perkDescription = getArguments().getString(ARG_PERK_DESCRIPTION);
}
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
View view = inflater.inflate(R.layout.fragment_perk, container, false);
TextView perkDescriptionTextView = (TextView) view.findViewById(R.id.perkDescription);
perkDescriptionTextView.setText(perkDescription);
return view;
}
}

The issue is that the viewpager should include tablayout inside the viewpager tags. This fixes the problem.
e.g:
<android.support.v4.view.ViewPager
android:id="#+id/viewpager"
android:layout_width="match_parent"
android:layout_height="fill_parent" >
<android.support.design.widget.TabLayout
android:id="#+id/sliding_tabs"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:theme="#style/MY.DIALOG"
card_view:tabTextColor="#666666"
card_view:tabSelectedTextColor="#666666" />
</android.support.v4.view.ViewPager>
