构造方法详细信息

ListView

public ListView(Element elem)

创建一个表示列表元素的新视图。

参数

elem - 创建视图的元素

方法详细信息

getAlignment

public float getAlignment(int axis)

计算列表所需的形状。

重写：

getAlignment在 BlockView

参数

axis - 可以是X_AXIS或Y_AXIS

结果

期望的跨度

另请参见：

View.getPreferredSpan(int)

paint

public void paint(Graphics g,
                  Shape allocation)

渲染使用给定的渲染表面和该表面上的区域。

重写：

paint在 BlockView

paintChild

protected void paintChild(Graphics g,
                          Rectangle alloc,
                          int index)

画一个孩子; 由paint（）调用。 默认情况下，这是所有它，但是一个子类可以使用它来绘制相对于孩子的东西。

重写：

paintChild在 BoxView类

参数

g - 图形上下文

alloc - 分配的区域来渲染孩子

index - 孩子的索引

setPropertiesFromAttributes

protected void setPropertiesFromAttributes()

描述从类别复制： BlockView

更新来自属性的任何缓存值。
