TabLayout+ViewPager的简单使用

  1、   build.gradle文件中加入

            compile 'com.android.support:design:22.2.0'

2、写Xml文件，注意TabLayout的三个属性

app:tabIndicatorColor="#0f0"                每个tab下方的下划线的颜色   
app:tabSelectedTextColor="#00f"             被选中的tab的文本颜色
app:tabTextColor="#f00"                     未被选中的tab的文本颜色

布局文件

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools" android:layout_width="match_parent"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    android:layout_height="match_parent"
    android:orientation="vertical"
    tools:context=".MainActivity">

    <android.support.design.widget.TabLayout
        android:id="@+id/tablayout"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:background="#777"
        app:tabIndicatorColor="#0f0"
        app:tabSelectedTextColor="#00f"
        app:tabTextColor="#f00"
        />


    <android.support.v4.view.ViewPager
        android:id="@+id/viewpager"
        android:layout_width="fill_parent"
        android:layout_height="0dp"
        android:layout_weight="1"
        android:background="#cccc"
        />

</LinearLayout>
