+        }
+    }
+~~~
+### module 下添加
+~~~
+implementation 'com.yanyi.benyanyi:picker:1.0.1'
+~~~
+
+或者
+~~~
+<dependency>
+  <groupId>com.yanyi.benyanyi</groupId>
+  <artifactId>picker</artifactId>
+  <version>1.0.1</version>
+  <type>aar</type>

+### 调用
+~~~
+PickerHelper.getInstance()

+            .show()

+
+#### 注意
+
+数据源使用的实体类需要继承PickerBean，并覆写其中的name及list
+
+例如：
+~~~

+    private var name: String = ""
+    var value: String? = null
+
+    @SerializedName("children")
+    private var children: List<Children> = arrayListOf()
+
+    override fun setName(name: String) {
+        this.name = name
+    }
+
+    override fun getName(): String {
+        return name
+    }
+
+    override fun setList(list: List<Children>) {
+        this.children = list
+    }
+
+    override fun getList(): List<Children>? {
+        return children
+    }
+
+    override fun toString(): String {
+        return "CityBean(name='$name', value=$value, children=$children)"
+    }
+
+}
+
+

+
+    @SerializedName("label")
+    private var name: String = ""

+
+    @SerializedName("children")
+    private var children: List<ChildrenX> = arrayListOf()
+
+    override fun setName(name: String) {
