Android ScrollView automatically scrolls to the bottom of the view

Question

I have created one activity which is containing one map, image and another text view, and I have added "scrollview" tag for it. But after the activity starts it scrolls to the end of the page automatically. Please tell me why this happens and how to stop it from moving to end so I can scroll it by myself.

<?xml version="1.0" encoding="utf-8"?> <ScrollView xmlns:android="http://schemas.android.com/apk/res/android" xmlns:tools="http://schemas.android.com/tools" android:layout_width="match_parent" android:layout_height="match_parent" android:paddingBottom="@dimen/activity_vertical_margin" android:paddingLeft="@dimen/activity_horizontal_margin" android:paddingRight="@dimen/activity_horizontal_margin" android:orientation="vertical" android:paddingTop="@dimen/activity_vertical_margin" tools:context="com.radikallab.earch.DetailsActivity" android:background="@drawable/background10"> <LinearLayout android:orientation="vertical" android:layout_width="match_parent" android:layout_height="match_parent"> <TextView android:id="@+id/title" android:layout_width="match_parent" android:layout_height="wrap_content" android:textSize="25dp" android:text="Title" android:textStyle="italic"/> <ImageView android:layout_width="match_parent" android:layout_height="wrap_content" android:src="@drawable/background4" android:id="@+id/iv"/> <TextView android:id="@+id/rat" android:layout_width="match_parent" android:layout_height="wrap_content" android:textSize="20sp" android:text="Title" android:textStyle="italic"/> <TextView android:id="@+id/addr" android:layout_width="match_parent" android:layout_height="wrap_content" android:textSize="17sp" android:text="Title" android:textStyle="italic"/> <WebView android:layout_width="match_parent" android:layout_height="500dp" android:layout_marginTop="10dp" android:id="@+id/webView" android:layout_gravity="center_horizontal" /> </LinearLayout>

I also face the same scenario once but adding the descendantFocusability attribute to the ScrollView's containing LinearLayout, solve my issue.

android:descendantFocusability="blocksDescendants"

you can use this as :

<LinearLayout android:layout_width="match_parent" android:layout_height="wrap_content" android:orientation="vertical" android:descendantFocusability="blocksDescendants" >

Is there any other way to block any sort of auto-scrolling that does not disable focus? I have TextViews with selection capability inside of the LinearLayout. Using this method disables text selection.

Set android:focusableInTouchMode="true" in your linear layout:

<LinearLayout android:orientation="vertical" android:layout_width="match_parent" android:focusableInTouchMode="true" android:layout_height="match_parent">

What worked for me is a combination of the answers from Punit Sharma and FAЯAƸ.

My issue was a scrollable view (RecyclerView) inside another scrollable view (NestedScrollView) -- same as your WebView inside a ScrollView.

Wrapping my inner scrollable view inside a FragmentLayout with attribute android:descendantFocusability="blocksDescendants" solved my auto-to-bottom-scrolling issue.

<androidx.core.widget.NestedScrollView android:layout_width="match_parent" android:layout_height="match_parent" app:layout_behavior="@string/appbar_scrolling_view_behavior"> <androidx.constraintlayout.widget.ConstraintLayout android:layout_width="match_parent" android:layout_height="wrap_content"> .... <FrameLayout android:layout_width="match_parent" android:layout_height="wrap_content" android:descendantFocusability="blocksDescendants" ...> <androidx.recyclerview.widget.RecyclerView android:id="@+id/image_gridview" android:layout_width="match_parent" android:layout_height="wrap_content"/> </FrameLayout> </androidx.constraintlayout.widget.ConstraintLayout> </androidx.core.widget.NestedScrollView>

In case you do want to set this manually using Java; Try this- it really works: Use FOCUS_UP to scroll to the top and FOCUS_DOWN to scroll it to the Bottom.

scrollView.post(new Runnable() { public void run() { scrollView.fullScroll(View.FOCUS_UP); }

Actually i found a simple answer for this just add "setfocusable(false)" in the associated java file.....in this case the "webview" coz its scroll there first....so add "webview.setfocusable(false)" in the associated webview java class.

Actually, we will face the scrolling problem if child inside ScrollView supports scrolling too like ListView and in your case WebView.

I found a similar question with some workaround. It supports vertical scrolling but horizontal scrolling is not supported if HTML page exceeds the WebView width.

See this for reference.
