Add the JitPack repository to your build file Add it in your root build.gradle at the end of repositories: ```java allprojects { repositories { ... maven { url 'https://jitpack.io' } } } ``` ### Step 2. Add the dependency ```java dependencies { implementation 'com.github.loonggg:RecyclerViewBanner:v1.2.3' } ``` ### Step 3. There are a few xml attributes to customise the RecyclerViewBanner * rvb_indicatorSelectedSrc 设置底部导航指示器或者点选中的样式 * rvb_indicatorUnselectedSrc 设置底部导航指示器或者点未选中状态的样式 * rvb_interval 设置轮播图滚动间隔时间 * rvb_showIndicator 设置是否显示底部指示导航小圆点 * rvb_indicatorSize 设置指示器的大小 * rvb_indicatorSpace 设置轮播指示器的间隔 * rvb_indicatorMargin 设置轮播指示器Indicator距离外边框的间距 * rvb_indicatorGravity 设置底部轮播导航指示器的位置 [left，center，right] * rvb_autoPlaying：是否自动滚动，true自动滚动，false禁止自动滚动 #### Example ```xml ``` ### Step 4. Impelement Listener ```java public class MainActivity extends AppCompatActivity { @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); RecyclerViewBanner recyclerViewBanner1 = (RecyclerViewBanner) findViewById(R.id.rv_banner_1); RecyclerViewBanner recyclerViewBanner2 = (RecyclerViewBanner) findViewById(R.id.rv_banner_2); RecyclerViewBanner recyclerViewBanner3 = (RecyclerViewBanner) findViewById(R.id.rv_banner_3); RecyclerViewBanner recyclerViewBanner4 = (RecyclerViewBanner) findViewById(R.id.rv_banner_4); RecyclerViewBanner recyclerViewBanner5 = (RecyclerViewBanner) findViewById(R.id.rv_banner_5); final List banners = new ArrayList<>(); banners.add(new Banner("https://timgsa.baidu.com/timg?image&quality=80&size=b9999_10000&sec=1487221110004&di=d6043e4b0c90ddf3ea5096c3d8eb8f58&imgtype=0&src=http%3A%2F%2Fimage.tianjimedia.com%2FuploadImages%2F2014%2F067%2F5116EPAUD762_1000x500.jpg")); banners.add(new Banner("https://timgsa.baidu.com/timg?image&quality=80&size=b9999_10000&sec=1487221129421&di=c085432cf7c15836f8a6479138740f39&imgtype=0&src=http%3A%2F%2Fimage85.360doc.com%2FDownloadImg%2F2015%2F05%2F0517%2F53199602_2.jpg")); banners.add(new Banner("https://timgsa.baidu.com/timg?image&quality=80&size=b9999_10000&sec=1490438881557&di=e61065ccc8d7b44591e1c4ba8df672ee&imgtype=0&src=http%3A%2F%2Fc.hiphotos.baidu.com%2Fzhidao%2Fpic%2Fitem%2F18d8bc3eb13533fa00428309a0d3fd1f41345b24.jpg")); banners.add(new Banner("https://timgsa.baidu.com/timg?image&quality=80&size=b9999_10000&sec=1490440243430&di=6f8d7c608a4e3fbe4130c93fc0f20850&imgtype=0&src=http%3A%2F%2Fimg3.duitang.com%2Fuploads%2Fitem%2F201509%2F09%2F20150909184342_mkrWc.jpeg")); banners.add(new Banner("https://timgsa.baidu.com/timg?image&quality=80&size=b9999_10000&sec=1490440556037&di=ade75ba29126922124b063a2a57873f7&imgtype=0&src=http%3A%2F%2Fi2.download.fd.pchome.net%2Ft_960x600%2Fg1%2FM00%2F0E%2F05%2FooYBAFTbGOmIDPSLAAXPs6l7AQMAACSVgDyBqkABc_L421.jpg")); recyclerViewBanner1.setRvBannerData(banners); recyclerViewBanner1.setOnSwitchRvBannerListener(new RecyclerViewBanner.OnSwitchRvBannerListener() { @Override public void switchBanner(int position, AppCompatImageView bannerView) { Glide.with(bannerView.getContext()) .load(banners.get(position).getUrl()) .placeholder(R.mipmap.ic_launcher) .into(bannerView); } }); recyclerViewBanner1.setOnRvBannerClickListener(new RecyclerViewBanner.OnRvBannerClickListener() { @Override public void onClick(int position) { Toast.makeText(MainActivity.this, "position: " + position, Toast.LENGTH_SHORT).show(); } }); recyclerViewBanner2.setRvBannerData(banners); recyclerViewBanner2.setOnSwitchRvBannerListener(new RecyclerViewBanner.OnSwitchRvBannerListener() { @Override public void switchBanner(int position, AppCompatImageView bannerView) { Glide.with(bannerView.getContext()) .load(banners.get(position).getUrl()) .placeholder(R.mipmap.ic_launcher) .into(bannerView); } }); recyclerViewBanner3.setRvBannerData(banners); recyclerViewBanner3.setOnSwitchRvBannerListener(new RecyclerViewBanner.OnSwitchRvBannerListener() { @Override public void switchBanner(int position, AppCompatImageView bannerView) { Glide.with(bannerView.getContext()) .load(banners.get(position).getUrl()) .placeholder(R.mipmap.ic_launcher) .into(bannerView); } }); recyclerViewBanner4.setIndicatorInterval(2000); recyclerViewBanner4.setRvBannerData(banners); recyclerViewBanner4.setOnSwitchRvBannerListener(new RecyclerViewBanner.OnSwitchRvBannerListener() { @Override public void switchBanner(int position, AppCompatImageView bannerView) { Glide.with(bannerView.getContext()) .load(banners.get(position).getUrl()) .placeholder(R.mipmap.ic_launcher) .into(bannerView); } }); recyclerViewBanner5.setRvBannerData(banners); recyclerViewBanner5.setOnSwitchRvBannerListener(new RecyclerViewBanner.OnSwitchRvBannerListener() { @Override public void switchBanner(int position, AppCompatImageView bannerView) { Glide.with(bannerView.getContext()) .load(banners.get(position).getUrl()) .placeholder(R.mipmap.ic_launcher) .into(bannerView); } }); } private class Banner { String url; public Banner(String url) { this.url = url; } public String getUrl() { return url; } } } ``` ### 公众号 欢迎大家关注我的微信公众号：非著名程序员（smart_android），更多好的原创文章均首发于微信订阅号：非著名程序员 ![](https://raw.githubusercontent.com/loonggg/BlogImages/master/%E5%85%AC%E4%BC%97%E5%8F%B7%E4%BA%8C%E7%BB%B4%E7%A0%81/erweima.jpg) # License ```xml Copyright 2017 loonggg Licensed under the Apache License, Version 2.0 (the "License"); you may not use this file except in compliance with the License.
