工具列表

  1. setBundle        :为 fragment 设置 arguments,返回 Fragment
  2. setArguments    :为 fragment 设置 arguments,返回对应类
  4. bundleK            :fragment 中 获取 arguments 的值

使用示例

  1. class TestFg : Fragment() {
  2.     //初始化 fragment 并传值
  3.     companion object {
  4.         private const val key = "key"
  5.         fun newInstance(): TestFg = TestFg().setArguments(key to "hello")
  7.         fun newInstance2(): Fragment = TestFg().setBundle(key to "value")
  8.     }
  10.     //获取传值
  11.     val value by bundleK<String>(key)
  12.     //获取传值,带默认值
  13.     val value2 by bundleK<String>(key){
  14.         "默认值"
  15.     }
  17.     override fun onViewCreated(view: View, savedInstanceState: Bundle?) {
  18.         super.onViewCreated(view, savedInstanceState)
  21.     }
  22. }
