5 | 6 | ## 使用方式 7 | 【最新版本号以[这里](https://github.com/Vanish136/IndexBar/releases)为准】 8 | 9 | #### ① 添加Gradle依赖 10 | ``` 11 | #last-version请查看上面的最新版本号 12 | #1.0.2版本开始后引用方式如下： 13 | implementation 'com.lwkandroid.library:IndexBar:last-version' 14 | 15 | #1.0.2版本以前引用方式如下： 16 | implementation 'com.lwkandroid:IndexBar:last-version' 17 | 18 | ``` 19 |
20 | 21 | #### ② 代码中使用 22 | ``` 23 | //在xml中定义 24 | //触摸时文字大小，默认15sp 34 | 35 | //代码中 36 | IndexBar mIndexBar = (IndexBar) findViewById(indexBar); 37 | //自定义索引数组，默认是26个大写字母 38 | mIndexBar.setTextArray(new CharSequence[]{...}); 39 | //添加相关监听 40 | mIndexBar.setOnIndexLetterChangedListener(new IndexBar.OnIndexLetterChangedListener(){ 41 | @Override 42 | public void onTouched(boolean touched) 43 | { 44 | //TODO 手指按下和抬起会回调这里 45 | } 46 | 47 | @Override 48 | public void onLetterChanged(CharSequence indexChar, int index, float y) 49 | { 50 | //TODO 索引字母改变时会回调这里 51 | } 52 | }); 53 | ``` 54 | **更详细的使用方法可参考Demo** 55 |
56 | 57 | ### 混淆配置 58 | 无需额外混淆配置 59 | 60 | ### 开源参考 61 | 1. Demo中实现`指定RecyclerView滚动到指定位置`的参考博客：http://blog.csdn.net/tyzlmjj/article/details/49227601 62 | 2. Demo中有引用我另外一个开源项目[RecyclerViewAdapter](https://github.com/Vanish136/RecyclerViewAdapter)，只是为了配合演示RecyclerView和IndexBar联动效果，实际开发过程可以去掉该库，两个库之间没有必然依赖（当然也很欢迎你一起了解下）。 63 |
