Fragment doesn't match_parent

Question

I just started to use fragments but I have problems to use them correctly.

This is my case. I'm using this BottomBar with some items, when user clicks on items fragments change. That's ok, but I can't set a match_parent on the second card's height. I'd like to use all the remaining space. This is the result:

This is code in my CDetails.java where I use the BottomBar and the FragmentManager:

 // BottomBar
            mBottomBar = BottomBar.attach(CustomersDetails.this, savedInstanceState);
            //mBottomBar.hideShadow();
            mBottomBar.noNavBarGoodness();
            mBottomBar.noResizeGoodness();
            //mBottomBar.noScalingGoodness();
            mBottomBar.noTabletGoodness();
            //mBottomBar.useFixedMode();
            mBottomBar.setItems(R.menu.bottom_navigation_customers);
            mBottomBar.setOnMenuTabClickListener(new OnMenuTabClickListener() {
                @Override
                public void onMenuTabSelected(@IdRes int menuItemId) {
                    if (menuItemId == R.id.bottomBarCustomerNotes) {

                        FragmentManager fragmentManager = getFragmentManager();
                        FragmentTransaction fragmentTransaction = fragmentManager.beginTransaction();
                        CustomersFragmentsNotes notes = new CustomersFragmentsNotes();
                        fragmentTransaction.replace(R.id.fragment_container, notes);
                        fragmentTransaction.commit();

                    }
                    if (menuItemId == R.id.bottomBarCustomerTickets) {

                        FragmentManager fragmentManager = getFragmentManager();
                        FragmentTransaction fragmentTransaction = fragmentManager.beginTransaction();
                        CustomersFragmentsTickets tcks = new CustomersFragmentsTickets();
                        fragmentTransaction.replace(R.id.fragment_container, tcks);
                        fragmentTransaction.commit();

                    }
                    if (menuItemId == R.id.bottomBarCustomerContracts) {

                        FragmentManager fragmentManager = getFragmentManager();
                        FragmentTransaction fragmentTransaction = fragmentManager.beginTransaction();
                        CustomersFragmentContracts cntrs = new CustomersFragmentContracts();
                        fragmentTransaction.replace(R.id.fragment_container, cntrs);
                        fragmentTransaction.commit();

                    }
                    if (menuItemId == R.id.bottomBarCustomerContacts) {

                        FragmentManager fragmentManager = getFragmentManager();
                        FragmentTransaction fragmentTransaction = fragmentManager.beginTransaction();
                        CustomersFragmentContacts cnts = new CustomersFragmentContacts();;
                        fragmentTransaction.replace(R.id.fragment_container, cnts);
                        fragmentTransaction.commit();

                    }
                }

                @Override
                public void onMenuTabReSelected(@IdRes int menuItemId) {

                }
            });

            //Setting colors
            mBottomBar.mapColorForTab(0, "#F44336");
            mBottomBar.mapColorForTab(1, "#7E57C2");
            mBottomBar.mapColorForTab(2, "#5C6BC0");
            mBottomBar.mapColorForTab(3, "#42A5F5");

This is my activity_cdetails.xml (the container):

And this is activity_c_fragment_notes.xml (first fragment):

        android:layout_height="match_parent"
        android:layout_marginBottom="10dp"
        android:layout_marginStart="10dp"
        android:layout_marginEnd="10dp"
        card_view:cardCornerRadius="5dp"
        card_view:cardBackgroundColor="#B2EBF2"
        card_view:cardElevation="7dp"
        >

        <TextView

        android:layout_height="wrap_content"

        android:text="This is Notes"
        />

    </android.support.v7.widget.CardView>

</LinearLayout>

Could anyone please tell me where I'm wrong?

Thanks in advance.

Edit

RRR solution works only on the default selected item, the first fragment. If I change item in the BottomBar second card's layout is the same as the pic I posted. Any other ideas?

Answer 1

use android:fillViewport=true for your ScrollView inside CoordinatorLayout

<ScrollView
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:fillViewport="true">

fillViewPort defines whether the scrollview should stretch its content to fill the viewport.
