How to prevent a scrollview from scrolling to a webview after data is loaded?

Question

So I have a fascinating problem. Despite the fact that I'm not manually or programmatically scrolling my view, my WebView is being automatically scrolled to after the data inside it loads.

I've got a fragment in a viewpager. When I first load the pager, it works as expected and everything is shown. But once I "flip the page" the data loads and the WebView pops up to the top of the page, hiding the views above it, which is undesirable.

Does anyone know how to prevent this from happening?

My layout looks like such:

<?xml version="1.0" encoding="utf-8"?> <ScrollView xmlns:android="http://schemas.android.com/apk/res/android"     android:layout_width="fill_parent"     android:layout_height="fill_parent"     android:background="@color/background" >      <LinearLayout         android:layout_width="match_parent"         android:layout_height="wrap_content"         android:orientation="vertical" >          <TextView             android:id="@+id/article_title"             android:layout_width="fill_parent"             android:layout_height="wrap_content"             android:layout_marginRight="10dp"             android:layout_marginLeft="10dp"             android:layout_marginTop="10dp"             android:layout_marginBottom="2dp"             android:text="Some Title"             android:textAppearance="?android:attr/textAppearanceLarge"             android:textColor="@color/article_title"             android:textStyle="bold" />          <LinearLayout             android:id="@+id/LL_Seperator"             android:layout_width="fill_parent"             android:layout_height="1dp"             android:layout_marginLeft="10dp"             android:layout_marginRight="10dp"             android:layout_marginTop="5dp"             android:layout_marginBottom="5dp"             android:background="@color/text"             android:orientation="horizontal" >         </LinearLayout>          <WebView             android:id="@+id/article_content"             android:layout_width="match_parent"             android:layout_marginRight="10dp"             android:layout_marginLeft="10dp"             android:layout_height="wrap_content" />          <TextView             android:id="@+id/article_link"             android:layout_width="fill_parent"             android:layout_height="wrap_content"             android:layout_marginBottom="5dp"             android:layout_marginTop="5dp"             android:layout_marginRight="10dp"             android:layout_marginLeft="10dp"             android:text="View Full Article"             android:textColor="@color/article_title"             android:textStyle="bold" />     </LinearLayout>  </ScrollView> 

I'm also not giving focus to anything. By default, it seems to automatically scroll to the WebView after it has loaded. How do I prevent this?

I had the same problem, after hours of trying several ideas, what finally worked for me was simply adding the descendantFocusability attribute to the ScrollView's containing LinearLayout, with the value blocksDescendants. In your case:

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

Haven't had the problem reoccur since.
