自学java和android三个月了，完全是看网上的****以及文章，说实话，网络大神们太神，有的代码高深莫测，有的“大神”写的代码小弟我有的根本看不通逻辑，哎，苦逼，谁让我是学俄语的，还是自学java和android，没人教啊，也没有做软件的朋友。。。自己写了几个小软件，一个悬浮球自己一直在用，挺简单的，没啥好说的，不扯了，进入正题：先看看目录架构。
类比较多，主Activity 用到了AppBarLayout+ViewPager,viewPager里三个fragment采用RecyclerView,可以伸缩ToolBar，喜爱列表写进了SQL，支持添加删除和清空，清空功能在右上的menu里，是单开了一个Thread,artist列表用了图片缓存，要不然加载起来卡的要死。搜索歌曲单做了一个空白activity，cardview里放一个editview，高度随键盘变化，也是用到了AppBarLayout。editview注册了addTextChangedListener。 本地列表添加了右侧快速导航栏，哎，这个逻辑是完全自己写的代码，别人是实现SectionIndexer接口，但是我真是看不懂网上大神们写的关于此接口的介绍和使用，没办法，又想实现这个功能，就只能自己写喽。逻辑很简单。写在了DataUtil里当工具用了。
歌词用的是一个大神写的代码，代码不多，但是好用~~
public static Boolean displayAA(List<Music> list,int position) { StringBuilder sb = new StringBuilder(26); for (int i = 0; i < list.size(); i++) { String name = list.get(i).getName(); String pinyin = Pinyin.toPinyin(name.charAt(0)); String pp = pinyin.substring(0, 1); sb.append(pp); } int A = sb.indexOf("A");int B = sb.indexOf("B"); int C = sb.indexOf("C");int D = sb.indexOf("D"); int E = sb.indexOf("E"); int F = sb.indexOf("F");int G = sb.indexOf("G");int H = sb.indexOf("H"); int I = sb.indexOf("I");int J = sb.indexOf("J"); int K = sb.indexOf("K");int L = sb.indexOf("L");int M = sb.indexOf("M"); int N = sb.indexOf("N");int O = sb.indexOf("O"); int P = sb.indexOf("P");int Q = sb.indexOf("Q");int R = sb.indexOf("R"); int S = sb.indexOf("S");int T = sb.indexOf("T"); int U = sb.indexOf("U");int V = sb.indexOf("V");int W = sb.indexOf("W"); int X = sb.indexOf("X");int Y = sb.indexOf("Y"); int Z = sb.indexOf("Z"); if (position ==A ||position ==B ||position ==C ||position ==D ||position ==E ||position ==F ||position ==G ||position ==H ||position ==I ||position ==J ||position ==K ||position ==L ||position ==M ||position ==N ||position ==O ||position ==P ||position ==Q || position ==R ||position ==S ||position ==T ||position ==U ||position ==V ||position ==W ||position ==X ||position ==Y || position ==Z ){ return true; }else{ return false; } } 上面的是决定哪个position对应的item显示A-Z这些字母。 下面的是触摸时让recyclerView找到应该滚动到的position。 public static int[] abc_index(List<Music> list){ StringBuilder sb = new StringBuilder(26); for (int i = 0; i< list.size(); i++){ String name = list.get(i).getName(); String pinyin = Pinyin.toPinyin(name.charAt(0)); String pp = pinyin.substring(0,1); sb.append(pp); } int A = sb.indexOf("A");int B = sb.indexOf("B"); int C = sb.indexOf("C");int D = sb.indexOf("D"); int E = sb.indexOf("E"); int F = sb.indexOf("F");int G = sb.indexOf("G");int H = sb.indexOf("H"); int I = sb.indexOf("I");int J = sb.indexOf("J"); int K = sb.indexOf("K");int L = sb.indexOf("L");int M = sb.indexOf("M"); int N = sb.indexOf("N");int O = sb.indexOf("O"); int P = sb.indexOf("P");int Q = sb.indexOf("Q");int R = sb.indexOf("R"); int S = sb.indexOf("S");int T = sb.indexOf("T"); int U = sb.indexOf("U");int V = sb.indexOf("V");int W = sb.indexOf("W"); int X = sb.indexOf("X");int Y = sb.indexOf("Y"); int Z = sb.indexOf("Z"); int[] abc_z = {A,B,C,D,E,F,G,H,I,J,K,L,M,N,O,P,Q,R,S,T,U,V,W,X,Y,Z}; return abc_z; }
A-Z的导航我做成悬浮窗了，在主activity里new出来的，viewpager翻页时sortView实现GONE。本来也写了一个在静态放在fragment里，但是因为ToolBar上下滑动，它也跟着动，烦，就写成悬浮了，测试了几个悬浮级别TYPE，实测LAST_APPLICATION_WINDOW 和 TYPE_APPLICATION_STARTING 最适用，既做到应用内的悬浮和可触摸，而且不会挡住我的悬浮球：）看完图片上代码吧，一句两句说不完，ca~~~
类太多了，布局就不上了，要不然这么多代码要死人的。。。

本来写了个内部接口，但是发现直接在此view里处理点击事件也是ok的，而更容易看逻辑。就把接口注掉了。
下面是用到的几个依赖
compile 'com.android.support:recyclerview-v7:26.1.0' compile 'com.android.support:design:26.1.0' compile 'com.jcodecraeer:xrecyclerview:1.5.9' compile 'com.android.support:palette-v7:26.1.0' compile 'com.github.promeg:tinypinyin:2.0.3'
最下面的是github上的一个汉字转拼音的。其它是android的支持包。
布局就不上了，没啥好说的。我看一下能不能上传完整包，可以的话就传上来。。
