Android Design Support Library（一）用TabLayout实现类似网易选项卡动态滑动效果

2016-09-26 18:09 603 查看

此前我们用HorizontalScrollView也实现了类似网易选项卡动态滑动效果，详见 Android选项卡动态滑动效果这篇文章

这里我们用TabLayout来实现这一效果。TabLayout是Android Design Support Library库中的控件。

Google在2015的IO大会上，给我们带来了更加详细的Material Design设计规范，同时，也给我们带来了全新的Android Design Support Library，在这个support库里面，Google给我们提供了更加规范的MD设计风格的控件。最重要的是，Android Design Support Library的兼容性更广，直接可以向下兼容到Android 2.2。

首先我们先来看看效果：

接下来开始实现

1. 配置build.gradle

在build.gradle加入如下代码

<code class="hljs rust has-numbering" style="display: block; padding: 0px; color: inherit; box-sizing: border-box; font-family: 'Source Code Pro', monospace;font-size:undefined; white-space: pre; border-radius: 0px; word-wrap: normal; background: transparent;">dependencies {
compile fileTree(<span class="hljs-keyword" style="color: rgb(0, 0, 136); box-sizing: border-box;">dir</span>: <span class="hljs-string" style="color: rgb(0, 136, 0); box-sizing: border-box;">'libs'</span>, include: [<span class="hljs-string" style="color: rgb(0, 136, 0); box-sizing: border-box;">'*.jar'</span>])
compile <span class="hljs-string" style="color: rgb(0, 136, 0); box-sizing: border-box;">'com.android.support:appcompat-v7:22.2.0'</span>

compile <span class="hljs-string" style="color: rgb(0, 136, 0); box-sizing: border-box;">'com.android.support:cardview-v7:22.2.0'</span>
}</code><ul class="pre-numbering" style="box-sizing: border-box; position: absolute; width: 50px; top: 0px; left: 0px; margin: 0px; padding: 6px 0px 40px; border-right-width: 1px; border-right-style: solid; border-right-color: rgb(221, 221, 221); list-style: none; text-align: right; background-color: rgb(238, 238, 238);"><li style="box-sizing: border-box; padding: 0px 5px;">1</li><li style="box-sizing: border-box; padding: 0px 5px;">2</li><li style="box-sizing: border-box; padding: 0px 5px;">3</li><li style="box-sizing: border-box; padding: 0px 5px;">4</li><li style="box-sizing: border-box; padding: 0px 5px;">5</li><li style="box-sizing: border-box; padding: 0px 5px;">6</li><li style="box-sizing: border-box; padding: 0px 5px;">7</li></ul><ul class="pre-numbering" style="box-sizing: border-box; position: absolute; width: 50px; top: 0px; left: 0px; margin: 0px; padding: 6px 0px 40px; border-right-width: 1px; border-right-style: solid; border-right-color: rgb(221, 221, 221); list-style: none; text-align: right; background-color: rgb(238, 238, 238);"><li style="box-sizing: border-box; padding: 0px 5px;">1</li><li style="box-sizing: border-box; padding: 0px 5px;">2</li><li style="box-sizing: border-box; padding: 0px 5px;">3</li><li style="box-sizing: border-box; padding: 0px 5px;">4</li><li style="box-sizing: border-box; padding: 0px 5px;">5</li><li style="box-sizing: border-box; padding: 0px 5px;">6</li><li style="box-sizing: border-box; padding: 0px 5px;">7</li></ul>

com.android.support:design:22.2.0就是我们需要引入的Android Design Support Library，其次我们还引入了Recyclerview和Cardview,还不了解这两个控件的同学可以看下面这两篇文章：

2.AppBarLayout,Toolbar与TabLayout

先看看主界面的布局（activity_tab_layout.xml）

这里用到了AppBarLayout和Toolbar，AppBarLayout是Android Design Support Library新加的控件继承自LinearLayout，它用来将Toolbar和TabLayout组合起来作为一个整体。Toolbar我们在这里不讲了，如果不熟悉可以看Android5.x
Toolbar和Palette应用解析这篇文章

这布局文件最关键的一点就是android.support.design.widget.TabLayout 标签中的app:tabMode=”scrollable”，他设置tab的模式为“可滑动的”,现在我们把这句话去掉，来看看效果：

上面的tab由于太多（13个）却不能滑动就重叠了。

接下来在java中引用（TabLayoutActivity.java）

基本所有的代码都讲到了，当然这种稍微复杂的效果TabLayout能够实现，那么简单的3，4个Tab滑动TabLayout实现起来更是不再话下，修改TabLayoutActivity的initViewPager方法（TabLayoutActivity.java)

我们只保留了4个Tab,然后去掉activity_tab_layout.xml android.support.design.widget.TabLayout 标签中的app:tabMode=”scrollable”

运行代码来看看效果
