将 Coroutine Dispatcher 的任务转移到另一个 Dispatcher

Question

我的问题很简单，给定 Dispatcher 1，您如何将 Dispatcher 1 的任务转移到另一个名为 Dispatcher 2 的 Dispatcher？

Answer 1

Not sure what transfer would mean but yes you can jump between threads . You can use withContext within a coroutine to switch between threads . Like so:

val customContext = newSingleThreadContext("CustomContext")

runBlocking(Dispatchers.Default) {
    // Started in DefaultDispatcher
    withContext(customContext) {
        // Working in CustomContext
    }
    // Back to DefaultDispatcher
}

runBlocking(Dispatchers.Unconfined) {
    // Started in main thread
    withContext(Dispatchers.Default) {
        // Working in DefaultDispatcher
    }
    // Back to main thread
}
