easyargs

With this small library you can easy navigate to activity or fragment. Convenient API allows you to put arguments (into Intent or Bundle) and to get them later.

class MasterActivity: AppCompatActivity {

  fun onItemChosen(item: Model) {
    start<DetailsActivity>(item.asArg())
  }
}

class DetailsActivity: AppCompatActivity {

  override fun onCreate(savedInstanceState: Bundle?) {
    super.onCreate(savedInstanceState)
    val item: Model = getArg()
  }
}

Usage

// Start activity. Allowed from context (activity, for example) or fragment
start<ExampleActivity>()

// With an argument
start<ExampleActivity>(item.asArg())
// Get the argument later
val item = getArg<YourModel>()

// Arguments can be the same type, but in this case you have to provide custom key for each one
start<ExampleActivity>(item.asArg("first"), anotherItem.asArg("second"))
// ..later
val anotherItem: YourModel = getArg("second")
val item: YourModel = getArg("first")

// Also you able to modify the Intent
start<ExampleActivity>() {
  type = ...
  data = ...
  ...
}

// If you want to get result from activity, you have to provide a request code
startForResult<ExampleActivity>(123, item.asArg())
// To wrap argument as result just use "asIntent" extension
val result = item.asArg().asIntent()

// Create a fragment
newInstance<ExampleFragment>(item.asArg())

Important

Only primitives, Serializable or Parcelable arguments allowed.
