Hi, (Not global, just for your case following the code you written in your fist post)
[code] button.setLayoutParams(new LinearLayout.LayoutParams(100,200)); Log.v(TAG, "Size = "+button.getLayoutParams().width + "," + button.getLayoutParams().height); [/code] getWidth and getHeight will not work here, as there is one UI thread. So, the button will not be redrawn while the tasks inside the event handler for the second button is not finished. So, the button will be redrawn with new size after fully executing the onClick handler of the other button, you are calling the time to execute the full handler "a very short timespan."
