1 Android CustomChoiceList Sample 2 =================================== 3 4 This sample demonstrates how to create custom checkable layouts, for use with ListView's choiceMode 5 attribute. 6 7 Introduction 8 ------------ 9 10 This sample demonstrates how to create custom single- or multi-choice [ListView][1] UIs on Android. 11 12 When a ListView has a `android:choiceMode` attribute set, it will allow users to "choose" one or more items. For 13 exmaple, refer to `res/layout/sample_main.xml` in this project: 14 15 ```xml 16 <ListView android:id="@android:id/list" 17 android:layout_width="match_parent" 18 android:layout_height="0dp" 19 android:layout_weight="1" 20 android:paddingLeft="@dimen/page_margin" 21 android:paddingRight="@dimen/page_margin" 22 android:scrollbarStyle="outsideOverlay" 23 android:choiceMode="multipleChoice" /> 24 ``` 25 26 The framework provides these default list item layouts that show standard radio buttons or check boxes next to a single 27 line of text: 28 29 - android.R.layout.simple_list_item_single_choice 30 - android.R.layout.simple_list_item_multiple_choice. 31 32 In some cases, you may want to customize this layout. When doing so, the root view must implement the Checkable 33 interface. For an example, see this sample's `CheckableLinearLayout` class. 34 35 Lastly, remember to use padding on your ListViews to adhere to the standard metrics described in the Android Design 36 guidelines. When doing so, you should set the `android:scrollbarStyle` attribute such that the scrollbar doesn't inset. 37 38 [1]: http://developer.android.com/reference/android/widget/ListView.html 39 40 Pre-requisites 41 -------------- 42 43 - Android SDK v21 44 - Android Build Tools v21.1.1 45 - Android Support Repository 46 47 Screenshots 48 ------------- 49 50 <img src="screenshots/1-main.png" height="400" alt="Screenshot"/> <img src="screenshots/2-settings.png" height="400" alt="Screenshot"/> 51 52 Getting Started 53 --------------- 54 55 This sample uses the Gradle build system.
