IllegalStateException :Scollview can host only one direct child

ERROR/AndroidRuntime(287): java.lang.RuntimeException: Unable to start activity ComponentInfo{cem.examples.reminder/cem.examples.reminder.main}: java.lang.IllegalStateException: ScrollView can host only one direct child

ScrollView tek elemanı içinde barındırabilir. İlla birden fazla elemanı içinde barındıracaksa ScrollView içine LinearLayout ve diğer elemanlarınızıda LinearLayout içine koyarak gösterebiliriz.

Hatalı olan:

 <ScrollView
  android:id="@+id/svVertical"
  android:layout_width="match_parent"
  android:layout_height="match_parent">
   <TextView
    android:id="@+id/tvTitle"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:text="BAŞLIIIIKK"
    android:textSize="26dip" />

   <TextView
    android:id="@+id/tvContent"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:text="İÇERİKKKK"
    android:textSize="20dip" />

   <Button
    android:id="@+id/btnNext"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:text="@string/btnNext" />
 </ScrollView>

Olması gereken:

<ScrollView
 android:id="@+id/svVertical"
 android:layout_width="match_parent"
 android:layout_height="match_parent">
  <LinearLayout
   android:layout_width="wrap_content"
   android:layout_height="wrap_content"
   android:orientation="vertical">
    <TextView
     android:id="@+id/tvTitle"
     android:layout_width="fill_parent"
     android:layout_height="wrap_content"
     android:text="BAŞLIIIIKK"
     android:textSize="26dip" />

    <TextView
     android:id="@+id/tvContent"
     android:layout_width="fill_parent"
     android:layout_height="wrap_content"
     android:text="İÇERİKKKK"
     android:textSize="20dip" />

    <Button
     android:id="@+id/btnNext"
     android:layout_width="fill_parent"
     android:layout_height="wrap_content"
     android:text="@string/btnNext" />
  </LinearLayout>
</ScrollView>
