13 | 14 | # 如何添加 15 | 16 | ### Gradle的引用方式 17 | 18 | #### 1.在Project的build.gradle 中添加仓库地址 19 | 20 | ``` 21 | //JitPack仓库 22 | maven { url 'https://jitpack.io' } 23 | ``` 24 | 25 | ##### 示例： 26 | 27 | ``` 28 | allprojects { 29 | repositories { 30 | ... 31 | //JitPack仓库 32 | maven { url 'https://jitpack.io' } 33 | } 34 | } 35 | ``` 36 | 37 | #### 2.在Module目录下的build.gradle中添加依赖 38 | 39 | ``` 40 | implementation 'com.github.jsyjst:Yuan-LrcView:LrcView-1.2' 41 | ``` 42 | 43 | ##### 示例 44 | 45 | ``` 46 | dependencies { 47 | implementation fileTree(dir: 'libs', include: ['*.jar']) 48 | implementation 'com.android.support:appcompat-v7:28.0.0' 49 | implementation 'com.android.support.constraint:constraint-layout:1.1.3' 50 | testImplementation 'junit:junit:4.12' 51 | androidTestImplementation 'com.android.support.test:runner:1.0.2' 52 | androidTestImplementation 'com.android.support.test.espresso:espresso-core:3.0.2' 53 | 54 | implementation 'com.github.jsyjst:Yuan-LrcView:LrcView-1.2' 55 | } 56 | ``` 57 | 58 | # 使用方法 59 | 60 | ## 1.第一步，在布局文件中声明 61 | 62 | ```xml 63 | 72 | ``` 73 | 74 | **属性说明:这些属性不设置的话为默认值** 75 | 76 | | 属性名 | 说明 | 默认值 | 77 | | ----------------- | ------------------------ | ---------- | 78 | | textSize | 歌词大小 | 16sp | 79 | | lineSpacing | 行间距，即歌词之间的距离 | 35dp | 80 | | lrcTextColor | 歌词的颜色 | Color.GRAY | 81 | | highLineTextColor | 当前播放歌词的颜色 | Color.BLUE | 82 | 83 | ## 2.第二步，在Java代码中传入歌词字符串和MediaPlayer对象,然后调用draw方法进行绘制 84 | 85 | ```java 86 | private LrcView lrcView; 87 | private MediaPlayer player; 88 | private String lrc; 89 | ..... 90 | lrcView.setLrc(lrc).setPlayer(player).draw(); 91 | ``` 92 | 93 | **说明** 94 | 95 | 传入的lrc必须是标准的歌词格式并且为字符串，目前来说只支持下列这种歌词格式： 96 | 97 | ```xml 98 | [ti:喜欢你] 99 | [ar:.]
