List View Not Scrolling In Fragment Using View Pager Inside Nestedscrollview

Hi there i needed to create layout like whatsapp, which scrolls the actionbar but not tabLayout. I used viewpager for loads fragment in it. In fragment i added listview but on List

Solution 1:

Okey first of all You warped ViewPager inside NestedScrollView, this is not necessary.

so change,

<android.support.v4.widget.NestedScrollViewandroid:layout_width="match_parent"android:layout_height="match_parent"android:layout_marginTop="?attr/actionBarSize"app:layout_behavior="@string/appbar_scrolling_view_behavior"><LinearLayoutandroid:layout_width="match_parent"android:layout_height="wrap_content"android:minHeight="1000dp"android:orientation="vertical"><android.support.v4.view.ViewPagerandroid:id="@+id/pager"android:layout_width="match_parent"android:layout_height="0dp"android:layout_weight="1"/></LinearLayout></android.support.v4.widget.NestedScrollView>

to,

<android.support.v4.view.ViewPager
     android:id="@+id/pager"
     android:layout_width="match_parent"
     android:layout_height="match_parent"
     android:layout_weight="1"
     app:layout_behavior="@string/appbar_scrolling_view_behavior"/>

Now Your are taking ListView, which is not working good with AppBarLayout, so I suggest you use RecyclerView instead.

Note: if you still want to use ListView you can use NonScrollListview wraping it under NestedScrollView.

NonScrollListView

publicclassNonScrollListViewextendsListView {

    publicNonScrollListView(Context context) {
         super(context);
    }

    publicNonScrollListView(Context context, AttributeSet attrs) {
         super(context, attrs);
    }

    publicNonScrollListView(Context context, AttributeSet attrs, int defStyle) {
         super(context, attrs, defStyle);
    }

    @OverridepublicvoidonMeasure(int widthMeasureSpec, int heightMeasureSpec) {
         intheightMeasureSpec_custom= MeasureSpec.makeMeasureSpec(Integer.MAX_VALUE >> 2, MeasureSpec.AT_MOST);
         super.onMeasure(widthMeasureSpec, heightMeasureSpec_custom);
         ViewGroup.LayoutParamsparams= getLayoutParams();
         params.height = getMeasuredHeight();
    }
}

And just change your fragment_one liske this.

<android.support.v4.widget.NestedScrollViewxmlns:android="http://schemas.android.com/apk/res/android"android:layout_width="match_parent"android:layout_height="match_parent"><packagename.NonScrollListViewandroid:id="@+id/listTest"android:layout_width="match_parent"android:layout_height="match_parent"></packagename.NonScrollListView></android.support.v4.widget.NestedScrollView>

I hope this will help you out. Happy coding..
