1 2 Android CustomChoiceList Sample 3 =================================== 4 5 This sample demonstrates how to create custom checkable layouts, for use with ListView's choiceMode 6 attribute. 7 8 Introduction 9 ------------ 10 11 This sample demonstrates how to create custom single- or multi-choice [ListView][1] UIs on Android. 12 13 When a ListView has a `android:choiceMode` attribute set, it will allow users to "choose" one or more items. For 14 exmaple, refer to `res/layout/sample_main.xml` in this project: 15 16 ```xml 17 <ListView android:id="@android:id/list" 18 android:layout_width="match_parent" 19 android:layout_height="0dp" 20 android:layout_weight="1" 21 android:paddingLeft="@dimen/page_margin" 22 android:paddingRight="@dimen/page_margin" 23 android:scrollbarStyle="outsideOverlay" 24 android:choiceMode="multipleChoice" /> 25 ``` 26 27 The framework provides these default list item layouts that show standard radio buttons or check boxes next to a single 28 line of text: 29 30 - android.R.layout.simple_list_item_single_choice 31 - android.R.layout.simple_list_item_multiple_choice. 32 33 In some cases, you may want to customize this layout. When doing so, the root view must implement the Checkable 34 interface. For an example, see this sample's `CheckableLinearLayout` class. 35 36 Lastly, remember to use padding on your ListViews to adhere to the standard metrics described in the Android Design 37 guidelines. When doing so, you should set the `android:scrollbarStyle` attribute such that the scrollbar doesn't inset. 38 39 [1]: http://developer.android.com/reference/android/widget/ListView.html 40 41 Pre-requisites 42 -------------- 43 44 - Android SDK 24 45 - Android Build Tools v24.0.2 46 - Android Support Repository 47 48 Screenshots 49 ------------- 50 51 <img src="screenshots/1-main.png" height="400" alt="Screenshot"/> <img src="screenshots/2-settings.png" height="400" alt="Screenshot"/> 52 53 Getting Started 54 --------------- 55 56 This sample uses the Gradle build system.
