I want to add some fragments to ViewPager in NestedScrollView.
Without adding fragments to ViewPager everything is ok and I can exit from app by device back button, but when I am adding fragment(s) to ViewPager I can not exit from app by pressing device back button.(Back button is working and for example can close soft keyboard)
this is my fragment code:
(empty fragment!)
public View onCreateView(#NonNull LayoutInflater inflater, #Nullable
ViewGroup container, #Nullable Bundle savedInstanceState) {
return inflater.inflate(R.layout.fragment_jadvalyab,container,false);
}
and this is my adapter:
public class MyFragmentPagerAdapter extends FragmentPagerAdapter {
private ArrayList<Fragment> fragmentsList = new ArrayList<>();
private ArrayList<String> fragsTitleList = new ArrayList<>();
public MyFragmentPagerAdapter(FragmentManager fm) {
super(fm);
}
public void addFragment(Fragment fragment,String title){
fragmentsList.add(fragment);
fragsTitleList.add(title);
}
#Nullable
#Override
public CharSequence getPageTitle(int position) {
return fragsTitleList.get(position);
}
#Override
public Fragment getItem(int position) {
return fragmentsList.get(position);
}
#Override
public int getCount() {
return fragmentsList.size();
}
}
Does anyone have an idea to solving this problem?
Thanks.
Edit:
Problem solved by removing NestedScrollingView from coordinator layout in activity_main and putting that in fragment layout (inside viewpager).
But still I don't know why device back button did not worked in former state.

I think the problem is occurring because you have used a third party library for ViewPager.
Just copy and paste the following code in the place of your "activity_main.xml" file.

I have initialized fragment to ViewPager like this
ViewPager viewPager2 = findViewById(R.id.viewpager);
MyFragmentPagerAdapter pagerAdapter2 = new MyFragmentPagerAdapter(getSupportFragmentManager());
pagerAdapter2.addFragment(TestFragment.createInstance(),"Home");
viewPager2.setAdapter(pagerAdapter2);
TabLayout tabLayout2 = findViewById(R.id.tabs);
tabLayout2.setupWithViewPager(viewPager2);
Here is the Testfragment.java class
public class TestFragment extends Fragment {
public static TestFragment createInstance() {
TestFragment profileFragment = new TestFragment();
return profileFragment;
}
#Nullable
#Override
public View onCreateView(LayoutInflater inflater, #Nullable ViewGroup container, #Nullable Bundle savedInstanceState) {
View rootView = inflater.inflate(R.layout.fragment_jadvalyab, container, false);
return rootView;

pagerAdapter2.addFragment(TestFragment.createInstance(),"Home");
viewPager2.setAdapter(pagerAdapter2);

}

Code for "fragment_jadvalyab.xml" is in te following
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout

android:layout_height="match_parent">
<TextView
android:layout_width="match_parent"
android:layout_height="match_parent"
android:text="Best Wishes"
android:gravity="center"/>
</LinearLayout>

Try this
#Override
public void onBackPressed() {
//Your Action
}

Override onBackPress(){} event in your MainActivity which holds your above xml layout.
#Override
public void onBackPressed() {
finish();
}

override OnBackPressed() method , or you can write your adapter as this.
public class Adapter extends FragmentStatePagerAdapter {
public Adapter (FragmentManager fm) {
super(fm);
}
// you can add fragments according to your requirement
#Override
public Fragment getItem(int position) {
Fragment fragment= null;
switch (position){
case 0:
fragment= new fragmentDay();
break;
case 1:
fragment= new fragmentWeek();
break;
case 2:
fragment= new fragmentMonth();
break;
}
return fragment;
}
#Override
public int getCount() {
return 3;
}
}
and inside activity pass fragment manager to adapter constructor.
fragmentManager= getSupportFragmentManager();
adapter= new Adapter(fragmentManager);
viewPager.setAdapter(adapter);
I have used tablayout with viewpager
tabLayout.setupWithViewPager(viewPager);
tabLayout.setTabsFromPagerAdapter(adapter);
tabLayout.getTabAt(0).setText("Day");
tabLayout.getTabAt(1).setText("Week");
tabLayout.getTabAt(2).setText("Month");
tabLayout.getTabAt(1).select();
tabLayout.setSelectedTabIndicatorColor(Color.WHITE);

Persistent bottom sheet

I have Persistent bottom sheet that include frame. I want to make full screen bottom sheet but I can't.

fragment transaction duplication

So to start things of i have a activity and inside that activity i have a tabbedlayout with 3 tabs which are my fragments, now my problem is when i try to pass a value from the activity to lets call it fragmentA the value gets passed correctly BUT the 3 fragments in my tabbedlayout get duplicated. This has been an issue for me for quite some time.
thanks in advance

Sorry for my poor English, first of all create fragment adapter like this
named MainFragmentAdapter.java
public class MainFragmentAdapter extends FragmentPagerAdapter {
private List<BaseFragment> fragments;
private List<String> titles;
public MainFragmentAdapter(FragmentManager fm) {
super(fm);
fragments = new ArrayList<>();
titles = new ArrayList<>();
}
#Override
public BaseFragment getItem(int position) {
return fragments.get(position);
}
#Override
public int getCount() {
return fragments.size();
}
#Nullable
#Override
public CharSequence getPageTitle(int position) {
return titles.get(position);
}
public void addFragment(String title, BaseFragment fragment) {
titles.add(title);
fragments.add(fragment);
}
}
now create a method in your activity class like this and call it in activity's onCreate method
private void setupViewPager() {
MainFragmentAdapter fragmentAdapter = new MainFragmentAdapter(getSupportFragmentManager());
fragmentAdapter.addFragment(getString(R.string.fragment_a), new FragmentA());
fragmentAdapter.addFragment(getString(R.string.fragment_b), new FragmentB());
fragmentAdapter.addFragment(getString(R.string.fragment_c), new FragmentC());
ViewPager mViewPager = findViewById(R.id.view_pager);
mViewPager.setAdapter(fragmentAdapter);
TabLayout mTabLayout = findViewById(R.id.tab_layout);
mTabLayout.setupWithViewPager(mViewPager);
mViewPager.setOffscreenPageLimit(fragmentAdapter.getCount() - 1);
mViewPager.setCurrentItem(0);
}
and your activity's xml is like this.
<?xml version="1.0" encoding="utf-8"?>

Recyclerview in Coordinatorlayout cutting off last item

I have a Bottom Navigation Bar, and a frame layout which is the fragment container. So when a an icon on a Bottom Navigation Bar is clicked, the fragment above changes.
In one of the fragment, I have a coordinator layout, collapsing toolbar, and recycler view. At the moment, the data is just a dummy data.
The problem that I am encountering is that whenever that fragment is inflated for the first time, the Recyclerview works fine and shows all of the items in the list. But when I change the fragment and come back to this fragment again, the last item of the Recyclerview is being cut off and is being hidden behind the Bottom Navigation Bar.
Here is my code for activity_home_screen.xml

Any help would be really appreciated. Thanks!

Remove this line from Event XML.
android:fitsSystemWindows="true"
And everything would be good to go.

override the fragment's setUserVisibleHint(),call view?.requestlayout()
override fun setUserVisibleHint(isVisibleToUser: Boolean) {
view?.requestLayout()
super.setUserVisibleHint(isVisibleToUser)
}

collapsingToolbarLayout.setTitle("Events");
this layout is hiding your last Recycler view, when this is shown your last item is hidden, when you set
collapsingToolbarLayout.setTitle("");
your last item is visible.
So, set padding to parent layout accordingly
