Android组件ScrollView怎么使用

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：

<?xml version="1.0" encoding="utf-8"?><ScrollView xmlns:android="http://schemas.android.com/apk/res/android"    android:layout_width="match_parent"    android:layout_height="match_parent">      <LinearLayout        android:layout_width="match_parent"        android:layout_height="wrap_content"        android:orientation="vertical">         <LinearLayout            android:layout_width="match_parent"            android:layout_height="wrap_content"            android:orientation="horizontal">            <View                android:layout_width="0dp"                android:layout_height="60dp"                android:layout_weight="2"                android:background="#07C2FB" />            <TextView                android:layout_width="0dp"                android:layout_height="60dp"                android:layout_weight="1"                android:gravity="center"                android:text="#07C2FB" />        </LinearLayout>         <LinearLayout            android:layout_width="match_parent"            android:layout_height="wrap_content"            android:orientation="horizontal">            <View                android:layout_width="0dp"                android:layout_height="60dp"                android:layout_weight="2"                android:background="#C60426FD" />            <TextView                android:layout_width="0dp"                android:layout_height="60dp"                android:layout_weight="1"                android:gravity="center"                android:text="#C60426FD" />        </LinearLayout>         <LinearLayout            android:layout_width="match_parent"            android:layout_height="wrap_content"            android:orientation="horizontal">            <View                android:layout_width="0dp"                android:layout_height="60dp"                android:layout_weight="2"                android:background="#032898" />            <TextView                android:layout_width="0dp"                android:layout_height="60dp"                android:layout_weight="1"                android:gravity="center"                android:text="#032898" />        </LinearLayout>        <LinearLayout            android:layout_width="match_parent"            android:layout_height="wrap_content"            android:orientation="horizontal">            <View                android:layout_width="0dp"                android:layout_height="60dp"                android:layout_weight="2"                android:background="#021173" />            <TextView                android:layout_width="0dp"                android:layout_height="60dp"                android:layout_weight="1"                android:gravity="center"                android:text="#021173" />        </LinearLayout>         <LinearLayout            android:layout_width="match_parent"            android:layout_height="wrap_content"            android:orientation="horizontal">            <View                android:layout_width="0dp"                android:layout_height="60dp"                android:layout_weight="2"                android:background="#504DAE" />            <TextView                android:layout_width="0dp"                android:layout_height="60dp"                android:layout_weight="1"                android:gravity="center"                android:text="#504DAE" />        </LinearLayout>        <LinearLayout            android:layout_width="match_parent"            android:layout_height="wrap_content"            android:orientation="horizontal">            <View                android:layout_width="0dp"                android:layout_height="60dp"                android:layout_weight="2"                android:background="#3C60A6" />            <TextView                android:layout_width="0dp"                android:layout_height="60dp"                android:layout_weight="1"                android:gravity="center"                android:text="#3C60A6" />        </LinearLayout>        <LinearLayout            android:layout_width="match_parent"            android:layout_height="wrap_content"            android:orientation="horizontal">            <View                android:layout_width="0dp"                android:layout_height="60dp"                android:layout_weight="2"                android:background="#282EA8" />            <TextView                android:layout_width="0dp"                android:layout_height="60dp"                android:layout_weight="1"                android:gravity="center"                android:text="#282EA8" />        </LinearLayout>        <LinearLayout            android:layout_width="match_parent"            android:layout_height="wrap_content"            android:orientation="horizontal">            <View                android:layout_width="0dp"                android:layout_height="60dp"                android:layout_weight="2"                android:background="#273523" />            <TextView                android:layout_width="0dp"

      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">         <LinearLayout            android:layout_width="match_parent"            android:layout_height="match_parent"            android:orientation="vertical">            <View                android:layout_width="200px"                android:layout_height="60dp"                android:layout_weight="2"                android:background="#2479CE" />             <TextView                android:layout_width="200px"                android:layout_height="60dp"                android:layout_weight="1"                android:gravity="center"                android:text="#2479CE" />        </LinearLayout>         <LinearLayout            android:layout_width="match_parent"            android:layout_height="match_parent"            android:orientation="vertical">            <View                android:layout_width="200px"                android:layout_height="60dp"                android:layout_weight="2"                android:background="#C97A06" />             <TextView                android:layout_width="200px"                android:layout_height="60dp"                android:layout_weight="1"                android:gravity="center"                android:text="#C97A06" />        </LinearLayout>         <LinearLayout            android:layout_width="match_parent"            android:layout_height="match_parent"            android:orientation="vertical">            <View                android:layout_width="200px"                android:layout_height="60dp"                android:layout_weight="2"                android:background="#68060E" />             <TextView                android:layout_width="200px"                android:layout_height="60dp"                android:layout_weight="1"                android:gravity="center"                android:text="#68060E" />        </LinearLayout>        <LinearLayout            android:layout_width="match_parent"            android:layout_height="match_parent"            android:orientation="vertical">            <View                android:layout_width="200px"                android:layout_height="60dp"                android:layout_weight="2"                android:background="#271904" />             <TextView                android:layout_width="200px"                android:layout_height="60dp"                android:layout_weight="1"                android:gravity="center"                android:text="#271904" />        </LinearLayout>          <LinearLayout            android:layout_width="match_parent"            android:layout_height="match_parent"            android:orientation="vertical">            <View                android:layout_width="200px"                android:layout_height="60dp"                android:layout_weight="2"                android:background="#673AB7" />             <TextView                android:layout_width="200px"                android:layout_height="60dp"                android:layout_weight="1"                android:gravity="center"                android:text="#673AB7" />        </LinearLayout>         <LinearLayout            android:layout_width="match_parent"            android:layout_height="match_parent"            android:orientation="vertical">            <View                android:layout_width="200px"                android:layout_height="60dp"                android:layout_weight="2"                android:background="#1B5834" />             <TextView                android:layout_width="200px"                android:layout_height="60dp"                android:layout_weight="1"                android:gravity="center"                android:text="#1B5834" />        </LinearLayout>         <LinearLayout            android:layout_width="match_parent"            android:layout_height="match_parent"            android:orientation="vertical">            <View                android:layout_width="200px"                android:layout_height="60dp"                android:layout_weight="2"                android:background="#680379" />             <TextView                android:layout_width="200px"                android:layout_height="60dp"                android:layout_weight="1"                android:gravity="center"                android:text="#680379" />        </LinearLayout>         <LinearLayout            android:layout_width="match_parent"            android:layout_height="match_parent"            android:orientation="vertical">            <View                android:layout_width="200px"                android:layout_height="60dp"                android:layout_weight="2"                android:background="#043485" />             <TextView                android:
