CardFragment

public class CardFragment
extends Fragment

java.lang.Object
↳	android.app.Fragment
	↳	android.support.wearable.view.CardFragment

在可展开的垂直滚动卡片中呈现内容。默认布局包含标题，图标和文本，但可能会被重写onCreateContentView(LayoutInflater, ViewGroup, Bundle) 。

还提供了其他方法来调整卡的外观，包括内容是否应该剪裁或显示为可展开，以及卡的最大高度。

Returns
`View`	Return the View for the fragment's UI, or null

Parameters
`bottomPadding`	`int`: the bottom padding

setContentPaddingLeft

void setContentPaddingLeft (int leftPadding)

设置内部卡的左边缘和卡片内容之间的填充。

Parameters
`leftPadding`	`int`: the left padding

setContentPaddingRight

void setContentPaddingRight (int rightPadding)

设置内部卡的右边缘和卡内容之间的填充。

Parameters
`rightPadding`	`int`: the right padding

setContentPaddingTop

void setContentPaddingTop (int topPadding)

设置内卡顶边和卡内容之间的填充。

Parameters
`topPadding`	`int`

setExpansionDirection

void setExpansionDirection (int direction)

调整卡片高度将扩大的方向。当通过滚动获得更多内容时，这也决定了哪个边缘以褪色边缘呈现。

Parameters
`direction`	`int`: a direction constant, either `EXPAND_UP` or `EXPAND_DOWN`

setExpansionEnabled

void setExpansionEnabled (boolean enabled)

启用可能比卡的容器更大的支持内容。当启用扩展时，内容大于卡片时，顶部或底部边缘将淡入以指示此情况。扩展系数也必须增加以允许卡的高度增加。

Parameters
`enabled`	`boolean`

setExpansionFactor

void setExpansionFactor (float factor)

将卡所允许的最大高度设置为父高度的倍数。如果启用了扩展功能，卡片将根据需要增加高度，以适应内容。
