Android组件ScrollView怎么使用

发布时间:2022-04-01 10:27:54 来源:亿速云 阅读:168 作者:iii 栏目:开发技术

今天小编给大家分享一下Android组件ScrollView怎么使用的相关知识点,内容详细,逻辑清晰,相信大部分人都还太了解这方面的知识,所以分享这篇文章给大家参考一下,希望大家阅读完这篇文章后有所收获,下面我们一起来了解一下吧。

概述

    ScrollView也是一个容器,它是FrameLayout的子类,它的主要作用就是将超出物理屏幕的内容显示出来,(就是滚动条效果)ScrollView提供垂直滚动,进而可将超出物理屏幕的内容显示出来。

      在一般情况下,可以将一个采用垂直方式布局组件的LinearLayout作为ScrollLayout容器的子组件,同时,在LinearLayout容器中可以显示超出屏幕物理高度的内容。

练习

这么说有点抽象,然后我们现在实现完成一个调试板颜色的显示,效果如下:(可以往下滚动)

代码:

Android组件ScrollView怎么使用

      当然了ScrollView只提供了垂直滚动条,若要使用水平滚动功能,则Android提供了HorizontalScrollView容器,HorizontalScrollView容器可以提供水平滚动,它的使用方法与ScrollView类似

HorizontalScrollView:

<?xml version="1.0" encoding="utf-8"?>
<HorizontalScrollView xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent">
 
 
    <LinearLayout
        android:layout_width="wrap_content"
        android:layout_height="match_parent"
        android:orientation="horizontal">

            android:layout_height="match_parent"

            <TextView
                android:layout_width="200px"
                android:layout_height="60dp"
