               导包: compile 'com.bigkoo:convenientbanner:2.0.5'

        第一步:布局

        <?xml version="1.0" encoding="utf-8"?> <RelativeLayout       xmlns:android="http://schemas.android.com/apk/res/android"    xmlns:tools="http://schemas.android.com/tools"    android:layout_width="match_parent"    android:layout_height="match_parent"    xmlns:app="http://schemas.android.com/apk/res-auto"    android:paddingBottom="@dimen/activity_vertical_margin"    android:paddingLeft="@dimen/activity_horizontal_margin"    android:paddingRight="@dimen/activity_horizontal_margin"    android:paddingTop="@dimen/activity_vertical_margin"    tools:context="com.example.myapplication.MainActivity">    <com.bigkoo.convenientbanner.ConvenientBanner        android:layout_width="match_parent"        android:layout_height="150dp"        android:id="@+id/con"        >     </com.bigkoo.convenientbanner.ConvenientBanner></RelativeLayout>

第二步:mian类里的代码逻辑

    第二步:Mian类里的代码逻辑
