HorizontalScrollView

public class HorizontalScrollView

extends

FrameLayout

java.lang.Object
↳	android.view.View
	↳	android.view.ViewGroup
		↳	android.widget.FrameLayout
			↳	android.widget.HorizontalScrollView

已知的直接子类 TabLayout

Layout container for a view hierarchy that can be scrolled by the user, allowing it to be larger than the physical display. A HorizontalScrollView is a

FrameLayout

, meaning you should place one child in it containing the entire contents to scroll; this child may itself be a layout manager with
a complex hierarchy of objects. A child that is often used is a

LinearLayout

in a horizontal orientation, presenting a horizontal array of top-level
items that the user can scroll through.

视图层次结构的布局容器，可以由用户进行滚动，允许它的内容比物理显示屏更大。HorizontalScrollView是一个

FrameLayout

，这意味着你应该在其中放置一个子项来滚动，其包含了所有的内容；这个子项本身可能是一个具有复杂的对象层次结构的布局管理器。子项经常在水平方位中，使用一个

LinearLayout

，其呈现了一个顶层项的水平排列，用户可以滚动浏览。

The

TextView

class also takes care of its own scrolling, so does not require a HorizontalScrollView, but using the two together is possible to
achieve the effect of a text view within a larger container.

TextView

类也负责它自己的滚动，因此不需要HorizontalScrollView，但是同时使用，可以实现在较大容器中的显示文本视图的效果。

HorizontalScrollView only supports horizontal scrolling. For vertical scrolling, use either

ScrollView

or

ListView

.

HorizontalScrollView只支持水平方向的滚动。对于垂直方向的滚动，请使用哦那个

ScrollView

或

ListView

。

Public方法
void	addView(View child, int index) Adds a child view. 添加一个子视图。
void	addView(View child) Adds a child view. 添加一个子视图。
void	addView(View child, ViewGroup.LayoutParams params) Adds a child view with the specified layout parameters. 添加具有指定布局参数的子视图。
void	addView(View child, int index, ViewGroup.LayoutParams params) Adds a child view with the specified layout parameters. 添加具有指定布局参数的子视图。
boolean	arrowScroll(int direction) Handle scrolling in response to a left or right arrow click. 处理左右箭头键的滚动。
void	computeScroll() Called by a parent to request that a child update its values for mScrollX and mScrollY if necessary. 由父项调用, 以请求子项在必要时，更新mScrollX和mScrollY的值。
boolean	dispatchKeyEvent(KeyEvent event) Dispatch a key event to the next view on the focus path. 向焦点路径上的下一个视图派发一个KeyEvent。
void	draw(Canvas canvas) Manually render this view (and all of its children) to the given Canvas. 手动将此视图 (及其所有子项) 渲染到指定的Canvas。
boolean	executeKeyEvent(KeyEvent event) You can call this function yourself to have the scroll view perform scrolling from a key event, just as if the event had been dispatched to it by the view hierarchy. 你可以自己调用这个函数，让滚动视图从一个按键事件中执行滚动，就好像事件已经被视图层次结构派发给它一样。
void	fling(int velocityX) Fling the scroll view Fling滚动视图
boolean	fullScroll(int direction) Handles scrolling in response to a "home/end" shortcut press. 处理按下“home/end”快捷键的滚动。
CharSequence	getAccessibilityClassName() Return the class name of this object to be used for accessibility purposes. 返回此对象的类名，用于辅助功能目的。
int	getMaxScrollAmount()
boolean	isFillViewport() Indicates whether this HorizontalScrollView's content is stretched to fill the viewport. 这个HorizontalScrollView的内容是否被拉伸，以填充视口（viewport）。
boolean	isSmoothScrollingEnabled()
boolean	onGenericMotionEvent(MotionEvent event) Implement this method to handle generic motion events. 实现此方法以处理普通的MotionEvent。
boolean	onInterceptTouchEvent(MotionEvent ev) Implement this method to intercept all touch screen motion events. 实现此方法可拦截所有触摸屏MotionEvent。
boolean	onTouchEvent(MotionEvent ev) Implement this method to handle touch screen motion events. 实现此方法，以处理触摸屏的MotionEvent。
boolean	pageScroll(int direction) Handles scrolling in response to a "page up/down" shortcut press. 处理按下“page up/down”快捷键的滚动。
void	requestChildFocus(View child, View focused) Called when a child of this parent wants focus 当此父项的子项请求焦点时调用。
boolean	requestChildRectangleOnScreen(View child, Rect rectangle, boolean immediate) Called when a child of this group wants a particular rectangle to be positioned onto the screen. 当此组的子项希望将特定的矩形置于屏幕上时调用。
void	requestDisallowInterceptTouchEvent(boolean disallowIntercept) Called when a child does not want this parent and its ancestors to intercept touch events with onInterceptTouchEvent(MotionEvent) . 当一个子项不希望此父项，通过 onInterceptTouchEvent(MotionEvent) 截获TouchEvent时调用。
void	requestLayout() Call this when something has changed which has invalidated the layout of this view. 当使此视图的布局失效事件发生时, 调用此方法。
void	scrollTo(int x, int y) Set the scrolled position of your view. 设置此视图到滚动位置。 This version also clamps the scrolling to the bounds of our child. 这个版本还将控制滚动到子项的边界。
void	setFillViewport(boolean fillViewport) Indicates this HorizontalScrollView whether it should stretch its content width to fill the viewport or not. 此HorizontalScrollView 是否应该拉伸它的内容宽度来填充视口（viewport）。
void	setOverScrollMode(int mode) Set the over-scroll mode for this view. 设置此视图的over-scroll模式。
void	setSmoothScrollingEnabled(boolean smoothScrollingEnabled) Set whether arrow scrolling will animate its transition. 设置箭头滚动是否使用动画转换。
boolean	shouldDelayChildPressedState() Return true if the pressed state should be delayed for children or descendants of this ViewGroup. 如果这个ViewGroup的子项要延迟按下的状态，则返回true。
final void	smoothScrollBy(int dx, int dy) Like scrollBy(int, int) , but scroll smoothly instead of immediately. 和 scrollBy(int, int) ，但将平滑的滚动，而不是立刻到目的位置。
final void	smoothScrollTo(int x, int y) Like scrollTo(int, int) , but scroll smoothly instead of immediately. 和 scrollTo(int, int) ，但将平滑的滚动，而不是立刻到目的位置。
