部分代码如下：

xmlns:ohos="http://schemas.huawei.com/res/ohos"

ohos:height="$float:singleCardViewHeight"

ohos:width="match_parent">

ohos:id="$+id:item_content_text"

ohos:height="$float:singleCardViewTextHeight"

ohos:width="match_content"

ohos:align_parent_left="true"

ohos:center_in_parent="true"

ohos:left_margin="$float:singleCardViewLeftMargin"

ohos:text_color="$color:textColorPrimary"

ohos:text_size="$float:textSizeBody1"/>

ohos:id="$+id:item_right_icon"

ohos:height="match_content"

ohos:width="match_content"

ohos:align_parent_right="true"

ohos:center_in_parent="true"

ohos:image_src="$graphic:icon_right_grey"

ohos:right_margin="$float:singleCardViewRightMargin"/>

ohos:id="$+id:item_right_content_text"

ohos:height="$float:singleCardViewRightTextHeight"

ohos:width="match_content"

ohos:center_in_parent="true"

ohos:left_of="$id:item_right_icon"

ohos:right_margin="$float:singleCardViewRightTextRightMargin"
