67This sample demonstrates how to create custom single- or multi-choice [ListView][1] UIs on Android.
68
69When a ListView has a `android:choiceMode` attribute set, it will allow users to "choose" one or more items. For
70exmaple, refer to `res/layout/sample_main.xml` in this project:
71
72```xml
73<ListView android:id="@android:id/list"
74    android:layout_width="match_parent"
75    android:layout_height="0dp"
76    android:layout_weight="1"
77    android:paddingLeft="@dimen/page_margin"
78    android:paddingRight="@dimen/page_margin"
79    android:scrollbarStyle="outsideOverlay"
80    android:choiceMode="multipleChoice" />
81```
82
83The framework provides these default list item layouts that show standard radio buttons or check boxes next to a single
84line of text:
85
86- android.R.layout.simple_list_item_single_choice
87- android.R.layout.simple_list_item_multiple_choice.
88
89In some cases, you may want to customize this layout. When doing so, the root view must implement the Checkable
90interface. For an example, see this sample's `CheckableLinearLayout` class.
91
92Lastly, remember to use padding on your ListViews to adhere to the standard metrics described in the Android Design
93guidelines. When doing so, you should set the `android:scrollbarStyle` attribute such that the scrollbar doesn't inset.
