How to scroll to a specific view and focus the view with scroll view in android

As many of the developer face this problem to scroll the view to specific view to focus the child view of scroll view. Let’s see an example, we have huge form where user need to fill to submit. But in the big form if user is missing any filling field or view then it is very difficult for user to finds the field which are missing to fill. Now we need to scroll the view to this specific view and focus this view for the user, then it becomes easy for the user to understand to finding the missing information to filled.

<ScrollView
            android:id="@+id/scrollView2"
            android:layout_width="match_parent"
            android:layout_height="0dp"
            card_view:layout_constraintBottom_toBottomOf="parent"
            card_view:layout_constraintEnd_toEndOf="parent"
            card_view:layout_constraintStart_toStartOf="parent">


  <LinearLayout
                android:id="@+id/detail_layout"
                android:layout_width="match_parent"
                android:layout_height="wrap_content"
                android:background="#f1f6fb"
                android:orientation="vertical"
                tools:visibility="visible">


                        <com.google.android.material.textfield.TextInputLayout
                            android:id="@+id/number_inputlayout">

                            <com.google.android.material.textfield.TextInputEditText
                                android:id="@+id/number_edittext"
                                android:layout_width="match_parent"
                                android:layout_height="wrap_content"
                                />

                        </com.google.android.material.textfield.TextInputLayout>

                        ..............
                       .............
   </LinearLayout>
        </ScrollView>

Here is solution.

private fun scrollToView(scrollViewParent: ScrollView, view: View) {
       // Get deepChild Offset
       val childOffset = Point()
       getDeepChildOffset(scrollViewParent, view.parent, view, childOffset)
       // Scroll to child.
       scrollViewParent.smoothScrollTo(0, childOffset.y)
   }

   private fun getDeepChildOffset(
       mainParent: ViewGroup,
       parent: ViewParent,
       child: View,
       accumulatedOffset: Point
   ) {
       val parentGroup = parent as ViewGroup
       accumulatedOffset.x += child.left
       accumulatedOffset.y += child.top
       if (parentGroup == mainParent) {
           return
       }
       getDeepChildOffset(mainParent, parentGroup.parent, parentGroup, accumulatedOffset)
   }

That is. Now it becomes easy to user to identify the view which is missing to filled. Ref 

Happy Coding.
