效果图片展示

1、配置依赖包

compile 'devlight.io:navigationtabbar:1.2.5'

2、布局中使用

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    xmlns:tools="http://schemas.android.com/tools"
    android:background="#423752"
    android:orientation="vertical">

    <android.support.v4.view.ViewPager
        android:id="@+id/vp_horizontal_ntb"
        android:layout_width="match_parent"
        android:layout_height="0dp"
        android:layout_weight="1"/>

    <devlight.io.library.ntb.NavigationTabBar
        android:id="@+id/ntb_horizontal"
        android:layout_width="match_parent"
        android:layout_height="60dp"
        app:ntb_badge_gravity="top"
        app:ntb_badge_position="right"
        app:ntb_badged="true"
        app:ntb_scaled="true"
        app:ntb_tinted="true"
        app:ntb_title_mode="all"
        app:ntb_titled="true"
        app:ntb_swiped="true"/>

</LinearLayout>

                }
            }
        }, 500);
    }
}

颜色资源配置（values下arrays中配置）

<?xml version="1.0" encoding="utf-8"?>
<resources>
    <string-array name="default_preview">
        <item>#df5a55</item>
        <item>#f9bb72</item>
        <item>#76afcf</item>
        <item>#dd6495</item>
        <item>#72d3b4</item>
    </string-array>
</resources>
