android - Fragment uses cutscenes, how to ensure that a method is executed after the cutscenes are completed?

Question

I set a 500ms cutscene for the fragment, and then made a network request in onViewCreate. When the network request starts, I will display a progress bar, but because the cutscene has not been completed at this time, the progress bar Before the interface is shown
How can I ensure that my method of requesting the network is executed after the cutscene is completed? (without using sleep)

Answer 1

postDelayed 500ms before executing network request

Answer 2

If you can monitor the animation, just monitor the animation. If you can't monitor the animation, just postDelayed.

Answer 3

Set a listener for the animation and execute the network request when the animation is completed

Answer 4

Drunk. Have you heard of life cycle?

Answer 5

Try making network requests in the OnActivityCreate() or OnStart() method

Answer 6

Since we cannot monitor the end of the Fragment animation, we can change our thinking and add a listener to the animation, and then set the progress bar to be visible in the onEnd method
