launch { whenStarted {} } 和 launchWhenStarted {} 完全一样吗?
Is launch { whenStarted {} } and launchWhenStarted {} exactly the same?
下面是不是一模一样?
lifecycleScope.launch {
whenStarted {
// Do something
}
}
和
lifecycleScope.launchWhenStarted {
// Do something
}
或者它们确实有一些不同的目的,因此提供了两种 API?
lifecycleScope.launchWhenStarted {
// Do something
}
只是
的简写
lifecycleScope.launch {
whenStarted {
// Do something
}
}
但是你可以做的是
lifecycleScope.launch {
//do something here in general
whenStarted {
// Do something onStart
}
whenCreated {
// Do something onCreate
}
whenResumed {
// Do something onResume
}
}
一天结束的方法:
launchWhenStarted
&
launchWhenResumed
&
launchWhenCreated
都在砧板上。以后会根据Android自己删除。所以我会避免使用它们,即使它可以为您节省一两行代码。
