I have a simple layout as follows :
use android:fillViewport="true" on the ScrollView may do it.
example in this thread.
I later found out that ,a similar situation has already been answered in the following thread https://stackoverflow.com/a/16885601/1474471 by @olefevre.
Adding an extra LinearLayout that surrounds the current LinearLayout with a padding and removing the inner LinearLayout's layout-margin solved the problem:
<?xml version="1.0" encoding="utf-8"?>
<ScrollView xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent" >
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="#D23456"
android:padding="10dp" >
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="#FFFFFF" >
<ImageView
android:layout_width="match_parent"
android:layout_height="800dp"
android:src="@drawable/ic_launcher" />
</LinearLayout>
</LinearLayout>
</ScrollView>
The solution posted by @Mehmet Katircioglu works well, but you can solve the problem simply changing the android:layout_margin to android:padding, without none extra view. Like this:
<?xml version="1.0" encoding="utf-8"?>
<ScrollView xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent" >
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="#D23456"
android:padding="10dp" >
<!-- Your content (ImageView, buttons...) -->
<LinearLayout/>
