public class WrapContentHeightViewPager extends ViewPager {

    public WrapContentHeightViewPager(Context context) {
        super(context);
    }

    public WrapContentHeightViewPager(Context context, AttributeSet attrs) {
        super(context, attrs);
    }

    @Override
    protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec) {

        int height = 0;
        for(int i = 0; i < getChildCount(); i++) {
            View child = getChildAt(i);
            child.measure(widthMeasureSpec, MeasureSpec.makeMeasureSpec(0, MeasureSpec.UNSPECIFIED));
            int h = child.getMeasuredHeight();
            if(h > height) height = h;
        }

        heightMeasureSpec = MeasureSpec.makeMeasureSpec(height, MeasureSpec.EXACTLY);

        super.onMeasure(widthMeasureSpec, heightMeasureSpec);
    }

}

This is what is used. Just add a flag of fillViewPort

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

          <LinearLayout
              android:layout_width="match_parent"
              android:layout_height="wrap_content"
              android:orientation="vertical"
              >
<android.support.design.widget.TabLayout
          android:id="@+id/tabLayout"
          android:layout_width="match_parent"
          android:layout_height="wrap_content"
          />
      <android.support.v4.view.ViewPager
          android:id="@+id/case_data_view_pager"
          android:layout_width="match_parent"
          android:layout_height="wrap_content"
          >
      </android.support.v4.view.ViewPager>
          </LinearLayout>
 </ScrollView>
