ScrollView in Android
In Android, a ScrollView is a view group that is used to make vertically scrollable views. A scroll view contains a single direct child only. In order to place multiple views in the scroll view, one needs to make a view group(like LinearLayout) as a direct child and then we can define many views inside it. A ScrollView supports Vertical scrolling only, so in order to create a horizontally scrollable view, HorizontalScrollView is used.
XML attributes of ScrollView
|android:fillViewport||Defines whether the scrollview should stretch its content to fill the viewport.|
|android:measureAllChildren||Determines whether to measure all children or just those in the VISIBLE or INVISIBLE state when measuring. Defaults to false.|
|android:alpha||alpha property of the view, as a value between 0 (completely transparent) and 1 (completely opaque).|
|android:background||A drawable to use as the background.|
|android:clickable||Defines whether this view reacts to click events.|
|android:contentDescription||Defines text that briefly describes content of the view.|
|android:id||Supply an identifier name for this view, to later retrieve it with View.findViewById() or Activity.findViewById().|
|android:isScrollContainer||Set this if the view will serve as a scrolling container, meaning that it can be resized to shrink its overall window so that there will be space for an input method.|
|android:minHeight||Defines the minimum height of the view.|
|android:minWidth||Defines the minimum width of the view.|
|android:onClick||Name of the method in this View’s context to invoke when the view is clicked.|
|android:padding||Sets the padding, in pixels, of all four edges.|
|android:scrollbars||Defines which scrollbars should be displayed on scrolling or not.|
|android:addStatesFromChildren||Sets whether this ViewGroup’s drawable states also include its children’s drawable states.|
|android:animateLayoutChanges||Defines whether changes in layout should cause a LayoutTransition to run.|
|android:clipChildren||Defines whether a child is limited to draw inside of its bounds or not.|
|android:clipToPadding||Defines whether the ViewGroup will clip its children and resize any EdgeEffect to its padding, if padding is not zero.|
|android:layoutAnimation||Defines the layout animation to use the first time the ViewGroup is laid out.|
|android:layoutMode||Defines the layout mode of this ViewGroup.|
|android:splitMotionEvents||Sets whether this ViewGroup should split MotionEvents to separate child views during touch event dispatch.|
This example demonstrates the steps involved to create a ScrollView in Android using Kotlin.
Step 1: Create a new project
- Click on File, then New => New Project.
- Choose “Empty Activity” for the project template.
- Select language as Kotlin.
- Select the minimum SDK as per your need.
Step 2: Modify strings.xml
Add some strings inside the strings.xml file to display those strings in the app.
