Which Activity method is called after all the layout methods?

I need to do something in an Activity after all the layout meth开发者_如何学JAVAods have been called, all the Views are in place and the Activity is ready to be displayed.

Which method can do that?

If you are trying to get a width of a view or something. This should work

Add this to your activity's onCreate

ViewTreeObserver vto = layout.getViewTreeObserver(); 
vto.addOnGlobalLayoutListener(new OnGlobalLayoutListener() { 
    @Override 
    public void onGlobalLayout() { 
        // Put your code here. 

        layout.getViewTreeObserver().removeOnGlobalLayoutListener(this); 
    } 
}); 

There's no magic method for that AFAIK. Suggest adding a Handler to your activity class, and post() a Runnable to it from onCreate() that contains the code you want to run.

If that's still too early you can postDelayed() instead.
