[Android] When the program execution Onstart () and Onresume ()? Online ! ! ! ! ! ! ! ! ! ! ! ! ! ! 1

If my program is
public class mainActivity extends Activity
{
public void OnCreat () {
super.onCreate (savedInstanceState);
setContentView (R.layout.main);
}
}

which did not perform OnStart () and OnResume (), how the simulator will enforce it ?

When executed Onstart () and Onresume it?

------ Solution ------------------------------------ --------
normal startup procedure : onCreate () -> onStart () -> onResume ();
normal exit : onPause () -> onStop () -> onDestory ()

an Activity starts another Activity: onPause () -> onStop (), and then return : onRestart () -> onStart () -> onResume ()

program by back exit : onPause () -> onStop () -> onDestory (), then enter : onCreate () -> onStart () -> onResume ();
press home to exit the program : onPause () -> onStop (), then enter : onRestart () -> onStart () -> onResume ();


------ Solution ------------------------------------ --------
will be executed after the onCreate onStart, and the screen has been displayed, but can not interact ; then perform onResume, then you can interact with the user .
add Log to see it, could not perform onStart, onResume your view on the show .

nor deep understanding of life cycle

your Activity inheritance Activity, if you do not replicate the method , it will call the parent class method

< br /> execution is the parent class onStart and onResume

Onstart what I'm asking is , when executed ( ) and Onresume (). . . . . .

I did not write the program code Onstart () and Onresume (). . . . . . . . . .

perform the entire procedure from the beginning mainActivity right ?

following execution onCreat (), then the program will perform over ah ?

not running start, resume, pause, stop, destroy ah ?

a subclass inherits a parent class , as my Activity inherit Activity. So, if there is no replication subclass superclass method , then the sub-class will automatically call the parent class's way?

If not, you have the wrong reply logical problems .

Yes onStart and onResume execution is the parent class .

subclass does not override , the direct parent Activity call this method the
