Android 中Banner的使用详解

首先倒入一个依赖： compile 'com.youth.banner:banner:1.4.9'

添加的权限：

<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />

 布局文件：

<com.youth.banner.Banner
  android:id="@+id/banner_id"
  android:layout_width="match_parent"
  android:layout_height="170dp"></com.youth.banner.Banner>

在MainActivity中写入的代码

String url1 = "http://api.kkmh.com/v1/topic_new/discovery_list?gender=0&sa_event=eyJwcm9qZWN0Ijoia3VhaWthbl9hcHAiLCJ0aW1lIjoxNDg3ODM5MDM5MzE1LCJwcm9wZXJ0aWVzIjp7IkhvbWVwYWdlVGFiTmFtZSI6IueDremXqCIsIlZDb21tdW5pdHlUYWJOYW1lIjoi54Ot6ZeoIiwiJG9zX3ZlcnNpb24iOiI0LjIuMiIsIkdlbmRlclR5cGUiOiLlpbPniYgiLCJGcm9tRmluZENhdGVnb3J5VGFiTmFtZSI6IuWFqOmDqCIsIklzQXV0b0xvYWQiOmZhbHNlLCIkbGliX3ZlcnNpb24iOiIxLjYuMzQiLCIkbmV0d29ya190eXBlIjoiV0lGSSIsIiR3aWZpIjp0cnVlLCIkbWFudWZhY3R1cmVyIjoic2Ftc3VuZyIsIkZyb21GaW5kVGFiTmFtZSI6IuaOqOiNkCIsIiRzY3JlZW5faGVpZ2h0Ijo1NzYsIkNhdGVnb3J5Ijoi5peg5rOV6I635Y-WIiwiSG9tZXBhZ2VVcGRhdGVEYXRlIjowLCJQcm9wZXJ0eUV2ZW50IjoiUmVhZEZpbmRQYWdlIiwiRmluZFRhYk5hbWUiOiLmjqjojZAiLCJhYnRlc3RfZ3JvdXAiOjQ2LCIkc2NyZWVuX3dpZHRoIjoxMDI0LCJGaW5kQ2F0ZWdvcnlUYWJOYW1lIjoi5YWo6YOoIiwiJG9zIjoiQW5kcm9pZCIsIlRyaWdnZXJQYWdlIjoiSG9tZVBhZ2UiLCIkY2FycmllciI6IkNNQ0MiLCIkbW9kZWwiOiJHVC1QNTIxMCIsIiRhcHBfdmVyc2lvbiI6IjMuOC4xIn0sInR5cGUiOiJ0cmFjayIsImRpc3RpbmN0X2lkIjoiQTo5MDUxMDQyNzYzNzU1MTA5Iiwib3JpZ2luYWxfaWQiOiJBOjkwNTEwNDI3NjM3NTUxMDkiLCJldmVudCI6IlJlYWRGaW5kUGFnZSJ9";
