The Toast in the Activity reports an error after the Activity is destroyed. The solution is to change the context to the application, toastcontext

ToastUtil. showShort (context, R. string. connection_fail );

Change

ToastUtil. showShort (BusinesslinkApplication. getInstance (), R. string. connection_fail );

Android inherits the view. I want to end the current Activity, but there is no Activity. I want to convert context to Activity.

Because activity is a subclass of Context, you can directly call the finish Method for context... Activity.

Q: Where is the Toast error in this android applet?

Toast. makeText (activity06.class, "female", Toast. LENGTH_SHORT). show ();
Change activity. class in this line to activity. this
The first parameter of the makeText method refers to the context object. The context object here is the activity itself, so the written activity. this indicates itself.
