I need some help with my android application. The problem I had faced is that I had created Base activity, that controls Drawer Layout and toolbar. When I am extending it in activity for Relative Layout and nested Recycle View, I get a problem that a can't scroll it (But, when activity is starting, I can catch the moment and do it, but one time). Another situation - I opened an application without extending Base activity in my activity for RecycleView and it works okay.

recyclerView.setHasFixedSize(true);

}
Thanks, everybody, who will help me
You first need to remove
adapter.notifyDataSetChanged()
After this if you use recycler view inside nested scrolling
You need to add a single line
recyclerView.setNestwdScrollingenable(false)
I resolved the problem. I replace my logic for recyclerview in frament, and mainly change, that I do is - in layout with appbar, I replaced <include layout="#layout/content"/> to outside of AppBarLayout and change line:
android:layout_height="match_parent"
android:background="#color/colorWhite"
to this:
android:layout_height="wrap_content"

Try this
Make below Changes in you code
First Change
Use this in your HomePage Fragment
View view = inflater.inflate(R.layout.home_page, container, false);
instead of
View view = inflater.inflate(R.layout.app_bar_main, container, false);
Second Change
Now in your home_page add android:layout_marginTop="?actionBarSize" in your FrameLayout
<?xml version="1.0" encoding="utf-8"?>
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:layout_width="match_parent"
android:layout_marginTop="?actionBarSize"
android:layout_height="match_parent"
android:orientation="vertical">
<android.support.v7.widget.RecyclerView
android:id="#+id/recycleView"
android:layout_width="match_parent"
android:layout_height="match_parent"/>
</FrameLayout>
Some Other suggestion
Use implementation instead of compile in your build.gradle
because
Configuration compile is obsolete and has been replaced with implementation.
It will be removed at the end of 2018
You are inflating app_bar_main.xml instead of home_page.xml inside the Fragment. Replace View view = inflater.inflate(R.layout.app_bar_main, container, false); with View view = inflater.inflate(R.layout.home_page, container, false);. And where is the view with ID R.id.rl?

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.

Try this
#Override

}
Override onBackPress(){} event in your MainActivity which holds your above xml layout.
#Override

finish();
}
override OnBackPressed() method , or you can write your adapter as this.
public class Adapter extends FragmentStatePagerAdapter {
public Adapter (FragmentManager fm) {

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);
im new in android im creating an app and i have a problem with a listfragment, because the list its showing but its overlapping the title bar(i had to add margin top to change that), and also im using a drawer and when im trying to open the list it shows over the options drawer too, letme paste you the code and the image so you can understan more:

your problem is your setting your list fragment to the whole view Id with this line
// android.R.id.content is the WHOLE screen of your Activity
transaction.add(android.R.id.content,fragmento,"fragmento");
transaction.commit();
Create a FrameLayout in your content_drawer_principal.xml:
<FrameLayout android:id="#+id/list_content"
android:layout_width="match_parent"
android:layout_height="match_parent"/>
then do:
transaction.add(R.id.list_content,fragmento,"fragmento");
transaction.commit();
UPDATE
The real problem here is that your telling your FragmentTransaction to load your FragmentoPrincipalChofer into android.R.id.content which is a reserved id
android.R.id.content gives you the root element of a view, without having to know its actual name/type/ID.
Revers the order of your activity layout, put list view brfore any other main content
Here, This is my implementation in java:
import static com.example.krsnv.kooc.R.id.nav_gro;

if (id == R.id.nav_account) {
Toast.makeText(Displayprofile.this, "my account",Toast.LENGTH_LONG).show();
}
else if (id == R.id.nav_settings)
{
Toast.makeText(Displayprofile.this,"settings",Toast.LENGTH_SHORT).show();
}

return true;
}
} );

When I click an item in the navigation drawer it doesn't show the Toast message. Here, setNavigationItemSelectedListener is not working So, what can be done to solve this issue ?
In order to use this setNavigationItemSelectedListener you should have menu as give below in res->menu folder
<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:android="http://schemas.android.com/apk/res/android">
<item
android:id="#+id/menu_payment"
android:checked="false"
android:icon="#drawable/ic_action_payment"
android:title="#string/menu_payment" />
<item
android:id="#+id/menu_history"
android:checked="false"
android:icon="#drawable/ic_action_history"
android:title="#string/menu_history" />
</menu>
Add this
#Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.navigation_menu, menu);
return true;
}
