13 | 项目中引用的方法： 14 | 15 | ### Step 1. Add the JitPack repository to your build file
16 | 步骤1.将JitPack存储库添加到构建文件中
17 | 项目的根build.gradle中添加以下代码： 18 | ```Java 19 | allprojects { 20 | repositories { 21 | ... 22 | maven { url 'https://jitpack.io' } 23 | } 24 | } 25 | ``` 26 | ### Step 2. Add the dependency
27 | 步骤2.build.gradle添加依赖项 28 | ```Java 29 | dependencies { 30 | implementation 'com.github.hnsycsxhzcsh:RulerView:v1.3' 31 | } 32 | ``` 33 | ### Step 3. Reference control in layout
34 | 步骤3. 布局中引用控件 35 | ```Java 36 | 45 | ``` 46 | ### Step 4. Add listener to the activity 47 | 步骤4. activity中添加监听 48 | ```Java 49 | mSizeViewKg = findViewById(R.id.sizeview_kg); 50 | 51 | //设置初始化值 52 | mSizeViewKg.setCurrentValue(89); 53 | 54 | mSizeViewKg.setOnValueChangeListener(new SizeViewValueChangeListener() { 55 | @Override 56 | public void onValueChange(int value) { 57 | //获取现在的值 58 | } 59 | }); 60 | ``` 61 | 我的博客地址：https://blog.csdn.net/m0_38074457/article/details/85305237 62 | 63 | If my control helps you, please help click on the top right corner, thank you!
