Recycler View not adjusting to match parent

Question

I have used a fragment inside which recyler view is used to load list elements.

Following is the layout file for fragment.

    <com.google.android.material.appbar.AppBarLayout
        android:id="@+id/languagebar"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        app:liftOnScroll="true">
        <com.google.android.material.appbar.CollapsingToolbarLayout
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            app:contentScrim="?attr/colorPrimary"
            app:expandedTitleGravity="top"
            app:expandedTitleMarginStart="5dp"
            app:expandedTitleMarginTop="5dp"
            android:layout_gravity="top"
            app:layout_scrollFlags="scroll|exitUntilCollapsed|snap">
            <com.google.android.flexbox.FlexboxLayout
                android:layout_width="match_parent"
                android:layout_height="30dp"
                android:layout_marginLeft="@dimen/spacing_large"
                android:layout_marginRight="@dimen/spacing_large"
                app:flexWrap="wrap"
                app:justifyContent="flex_start">

                <Button
                    style="@style/Widget.AppCompat.Button.Borderless.Colored"
                    android:id="@+id/buttonEnglish"
                    android:layout_width="wrap_content"
                    android:layout_height="wrap_content"
                    android:background="@drawable/btn_rounded_yellow_white"
                    android:onClick="outletTypeClick"
                    android:text="English"
                    android:textAllCaps="false"
                    android:textColor="@color/grey_80" />

                <Button
                    style="?android:attr/borderlessButtonStyle"
                    android:id="@+id/buttonHindi"
                    android:layout_width="wrap_content"
                    android:layout_height="wrap_content"
                    android:background="@drawable/btn_rounded_yellow_white"
                    android:onClick="outletTypeClick"
                    android:text="Hindi"
                    android:textAllCaps="false"
                    android:textColor="@color/grey_80" />

            </com.google.android.flexbox.FlexboxLayout>

        </com.google.android.material.appbar.CollapsingToolbarLayout>

    </com.google.android.material.appbar.AppBarLayout>
    <androidx.recyclerview.widget.RecyclerView
        android:id="@+id/recyclerView"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:orientation="vertical"
        android:scrollbars="none"
        android:scrollingCache="true"
        app:layout_behavior="@string/appbar_scrolling_view_behavior"/>

</androidx.coordinatorlayout.widget.CoordinatorLayout>

Following is the initialization of recylerview inside fragment -

public View onCreateView(LayoutInflater inflater, ViewGroup parent, Bundle savedInstanceState) {
    // Defines the xml file for the fragment
    View rootView = inflater.inflate(R.layout.fragment_timeline1, parent, false);
    recyclerView = (RecyclerView) rootView.findViewById(R.id.recyclerView);
    RecyclerLinearLayoutManager recyclerLinearLayoutManager =
            new RecyclerLinearLayoutManager(rootView.getContext(), RecyclerView.VERTICAL, false);

    recyclerView.setLayoutManager(recyclerLinearLayoutManager);

    recyclerView.setHasFixedSize(true);

Here is the code from viewadapter -

@Override
    public RecyclerView.ViewHolder onCreateViewHolder(ViewGroup viewGroup, int viewType) {

        RecyclerView.ViewHolder viewHolder;
        LayoutInflater inflater = LayoutInflater.from(viewGroup.getContext());
        switch (viewType) {
            case TITLE:
                View v1 = inflater.inflate(R.layout.item_timeline_title, viewGroup, false);
                v1.setMinimumWidth(viewGroup.getMinimumWidth());
                viewHolder = new TitleViewHolder(v1);
                break;
            case HEADLINE:
                View v2 = inflater.inflate(R.layout.item_timeline_headline, viewGroup, false);
                viewHolder = new ViewHolder1(v2);
                break;
            .....
        }

        return viewHolder;
    }

Adding row item's xml.

In reference to the attached image - When I set image and text in layout file itself, it is occupying more width(as shown in attached screenshot). Whereas when I load the image and text via code, view renders to 20% of width. Also, the width of the recyler-view-section(as in below image) remains same in both landscape and portrait mode. Above observations looks like recyler-view width is rendering as wrap-content and not as match_parent. But I am not able to understand why this is happening as I have not used that logic in my code.

Answer 1

As you are loading fragment in the activity, check your FrameLayout container, you could have set its width to wrap_content, please change it to match_parent.
