2. This.runonuithread (new Runnable () {
4. @Override
6. public Void Run () {
8. try {
10. Thread.Sleep (+ 5);
12. } catch (Interruptedexception e) {

16. }
18. Inputmethodutils.show (context, editText);
20. System.out.println ("xx");
22. }
24. });
26. System.out.println ("xxxxxx");

In OnCreate, perform the change method. Execution results are as follows

Xx

xxxxxxx

It should also be understood that the system has only one (unique) independent main thread--uithread, all related to the interface is synchronous execution
