Modify src/AndroidSpinnerExampleActivity.java file to create a simple list view with items which are showing as spinner items You will use Android studio to create an Android application and name it as AndroidSpinnerExample under a package. To experiment with this example, you need to run this on an actual device on after developing the application according to the steps below. This example demonstrates the category of computers, you need to select a category from the category. When you are using Gmail application you would get drop down menu as shown below, you need to select an item from a drop down menu. Import 7.app.Spinner allows you to select an item from a drop down menuįor example. Step 3: Now Open src -> package -> MainActivity. So we have to jointly put 10 buttons inside Linear Layout to make it one child. Important Note: Remember ScrollView can hold only one direct child. Here we are creating a Relative Layout having 10 buttons which are nested in Linear Layout and then in ScrollView. Step 2: Open res -> layout -> activity_main. Fill the forms and click “Finish” button. Select File -> New -> New Project -> Android Application Project (or) Android Project. Step 1: Create a new project in Android Studio and name it scrollviewExample. Below is the code and final Output we will create: Įxample 1: In this example we will use 10 button and scroll them using ScrollView in vertical direction. By default scrollbars is shown in vertical direction in scrollView and in horizontal direction in HorizontalScrollView.īelow is scrollbars attribute’s example code in which we set the scrollbars in vertical direction.

Here is how Scroll View looks in Android:īelow is HorizontalScrollView syntax in Android is: Important Note 2: In android default ScrollView is used to scroll the items in vertical direction and if you want to scroll the items horizontally then you need to implement horizontal ScrollView. Just because it effectively forces the List View to display its entire list of items to fill up the infinite container supplied by a ScrollView so we don’t use it with List View. More importantly, doing this affects all of the important optimizations in a List View for dealing with large lists(list items). Important Note 1: We never use a Scroll View with a ListView because List View is default scrollable(i.e. ScrollView in Android Studio Design: It is present inside Containers > ScrollView or HorizontalScrollView Then after enclosing them in a standard layout, enclose the whole layout in ScrollView to make all the element or views scrollable. You can specify height and width in dp(density pixel) or px(pixel). You can specify layout_width and layout_height to adjust width and height of screen. This means that, if you have complex layout with more views(Buttons, TextViews or any other view) then you must enclose them inside another standard layout like Table Layout, Relative Layout or Linear Layout.
