按下按钮后延迟

Question

After I press a button, Android parse a JSON file and pick the info it needs. Until yesterday, I was using an external library created by a user and it worked perfectly. But now, I don't want to depend on him, so I've searching info about Google's GSON. I've implemented this library with no problem, but now, after pressing the button that opens a new activity there's a delay.

This delay is due to the connection and parsing that are done before the activity shows.

How can I force the app to wait the Internet connection until de Activity is shown? It's a lil bit uncomfortable because after pressing the button, it seems that the app has frozen, but after all data is loaded, the new activity appears.

Thank you in advance!

Answer 1

Use AsyncTask or Handler for network operations. Do never put "long time" operations into the UI thread

使用asyncTask ..如果服务器通信成功，则显示新的Activity或者退出..

它是可能的，通过Handler和AsyncTask看到这个如何在Android onClick函数中设置延迟你会得到如何使用Handler并看到这个为Asynctask https://stackoverflow.com/questions/7644567/need-a-simple-example -用于-Android的的AsyncTask
