(感谢[guodongAndroid](https://github.com/guodongAndroid)) 1.0.7 * 默认不再显示左侧的悬浮气泡 * 默认排序方式改为快速排序，提供一个MODE_NONE的排序方式 1.0.5 为HeaderView/FooterView添加: * `indexableLayout.removeHeaderAdapter();` * `headerAdapter.addData()` * `headerAdapter.removeData()` # 如何使用 ### gradle 项目下app的build.gradle中依赖： ````xml compile 'me.yokeyword:indexablerecyclerview:1.3.0' compile 'com.android.support:appcompat-v7:你使用的版本号' compile 'com.android.support:recyclerview-v7:你使用的版本号' ```` ### Xml ````xml // IndexBar：text lineSpace ```` ### 3步集成 **1、实体类实现IndexableEntity** ````java public class CityEntity implements IndexableEntity { ... private String name; private String pinyin; @Override public String getFieldIndexBy() { return name; // return 你需要根据该属性排序的field } @Override public void setFieldIndexBy(String indexByField) { this.name = indexByField; // 同上 } @Override public void setFieldPinyinIndexBy(String pinyin) { this.pinyin = pinyin; // 保存排序field的拼音,在执行比如搜索等功能时有用 （若不需要，空实现该方法即可） } } ```` **2、继承IndexAdapter** ````java public class CityAdapter extends IndexableAdapter { @Override public RecyclerView.ViewHolder onCreateTitleViewHolder(ViewGroup parent) { // 创建 TitleItem 布局 } @Override public RecyclerView.ViewHolder onCreateContentViewHolder(ViewGroup parent) { // 创建 内容Item 布局 } @Override public void onBindTitleViewHolder(RecyclerView.ViewHolder holder, String indexTitle) { // 填充 TitleItem 布局 } @Override public void onBindContentViewHolder(RecyclerView.ViewHolder holder, CityEntity entity) { // 填充 内容Item 布局 } } ```` **3、绑定视图和数据** ````java // 支持LinearLayoutManager, GridLayoutManager indexableLayout.setLayoutManager(LayoutManager); CityAdapter adapter = new CityAdapter(this); indexableLayout.setAdapter(adapter); // 排序过程是异步的 另有setDatas(mDatas,IndexCallback callback) // callback在datas异步排序结束后回调 adapter.setDatas(mDatas); // 另有setOnItemTitleClickListener(listener)，点击TitleItem点击事件以及LongClick adapter.setOnItemContentClickListener(listener); ```` # 拓展 ### 1、设置 索引悬浮提示框 风格 ````java // 前者Material Design风格右侧气泡 ， 后者 居中 IOS风格气泡 indexableLayout.setOverlayStyle_MaterialDesign(int Color) & setOverlayStyle_Center() ```` ### 2、多音字处理 多音字处理得益于使用了[TinyPinyin](https://github.com/promeG/TinyPinyin)，可以如下设置： ````java // 添加中文城市词典 Pinyin.init(Pinyin.newConfig().with(CnCityDict.getInstance()); // 添加自定义词典 Pinyin.init(Pinyin.newConfig() .with(new PinyinMapDict() { @Override public Map mapping() { HashMap map = new HashMap(); map.put("重庆", new String[]{"CHONG", "QING"}); return map; } })); ```` ### 3、添加自定义HeaderView，FooterView ````java indexableLayout.addHeaderAdapter(IndexableHeaderAdapter adapter) // 添加HeaderView indexableLayout.addFooterAdapter(IndexableFooterAdapter adapter) // 添加FooterView // 3个参数分别对应:IndexBar的索引,HeaderTitle,传入的Header数据源,此处泛型T可以是任何实体类,不需要和主Adapter类型一致 // 如果不想显示某块视图，则传入null即可： 比如不想显示 HeaderTitle， 则indexTitle传入null； IndexableHeaderAdapter(String index, String indexTitle, List datas){ // 需要实现3个方法： public abstract int getItemViewType(); // 每个HeaderView的type应当不同 public abstract RecyclerView.ViewHolder onCreateContentViewHolder(ViewGroup parent); public abstract void onBindContentViewHolder(RecyclerView.ViewHolder holder, T entity); } // 如果想添加的HeaderView，和主Adapter的布局完全一致，则可以使用: new SimpleHeaderAdapter(IndexableAdapter adapter, String index, String indexTitle, List datas); ```` ### 4、更改排序规则 默认根据**全拼音排序**，可根据需求更改为**按首字母排序**: ````java // 设置排序规则： // MODE_FAST:按首字母排序（默认）；MODE_ALL_LETTERS:全字母比较，效率较低； MODE_NONE:字母模块内不排序，效率最高 indexableLayout.setCompareMode(@CompareMode int mode); // 自定义排序规则 indexableLayout.setComparator(yourComparator); ```` > 更多细节使用，参见Demo ## 致谢 [TinyPinyin](https://github.com/promeG/TinyPinyin) ================================================ FILE: build.gradle ================================================ // Top-level build file where you can add configuration options common to all sub-projects/modules. buildscript { repositories { jcenter() } dependencies { classpath 'com.android.tools.build:gradle:2.3.1' // NOTE: Do not place your application dependencies here;
