The select\_dialog\_singlechoice\_material.xml layout from the plattform source uses the android:checkMarkGravity="start"attribute:

<CheckedTextView xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@android:id/text1"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:minHeight="?android:attr/listPreferredItemHeightSmall"
android:textAppearance="?android:attr/textAppearanceMedium"
android:textColor="?android:attr/textColorAlertDialogListItem"
android:gravity="center_vertical"
android:paddingStart="@dimen/alert_dialog_padding_material"
android:paddingEnd="@dimen/alert_dialog_padding_material"
android:checkMark="?android:attr/listChoiceIndicatorSingle"
android:checkMarkGravity="start"
android:ellipsize="marquee" />

```

However I am unable to use this attribute in my project as I get the following error:

> 
> Error:(15) No resource identifier found for attribute 'checkMarkGravity' in package 'android'
> 
> 
> 

Is it possible to use this attribute in some way? I am compiling for api 21, so this should be okay:

```
minSdkVersion 21
targetSdkVersion 21

```
