多层级选择器。默认提供了一个由其实现的中国大陆省市区选择器 RegionPicker。

开始使用

在项目根目录中的 build.gralde 文件中：

allprojects {
    repositories {
        ...
        maven { url 'https://jitpack.io' }
    }
}

在 Module 中的 build.graldle 文件中添加依赖：

dependencies {
    implementation 'com.github.stingzhan:MultistagePicker:1.0.0'
}

用例

Step1: 创建一个 MultistagePickerDataProvider 为选择器提供数据，示例：

    val options = mapOf(
        "业务相关" to listOf("业务员", "区域经理", "业务经理", "业务总监"),
        "销售相关" to listOf("销售员", "柜长", "销售经理", "展厅经理", "销售总监")
    )

    val dataProvider = object : MultistagePickerDataProvider() {
        private val keys = listOf("Key1", "Key2")

        override fun stageKeys(): List<String> {
            return keys
        }

        override fun stageData(stageKey: String, upperStageSelectedOptions: Map<String, String>): List<String>? {
            return when (stageKey) {
                "Key1" -> options.keys.toList()
                "Key2" -> {
                    val key = upperStageSelectedOptions["Key1"]
                    options[key]
                }
                else -> null
            }
        }
    }

Step2: 创建一个选择器，示例：

    val simplePicker = MultistagePickerDialog(this, dataProvider)
    simplePicker.setOnPickCompletedListener { selectedOptions ->
        // selectedOptions 存放着选取结果
    }

Step3: 弹出选择器, 示例：

    simplePicker.show()

省市区选择器使用：

    val regionPicker = RegionPicker(this)
    regionPicker.setOnAddressPickSuccessListener { region ->
        Log.i("ResultTag", "结果： ${region.province} - ${region.city} - ${region.district}")
    }
    regionPicker.show()

设置预选中的省市区值：

    regionPicker.setDefaultRegion(Region("广东省", "深圳市", "龙岗区"))
