[android-developers] Window token is always null

I find that View.getWindowToken() always returns null, even when invoked from the main Activity during onCreate. For example: TextView tv = new TextView(this); tv.setText(Hello, Android); setContentView(tv); tv.getWindowToken(); // will equal null Manually adding it to the window manager

That's because the view hierarchy hasn't been added to the window manager. You find out it has been added in View.onAttachedToWindow(). On Mon, Jan 17, 2011 at 8:41 AM, APF adriennef...@gmail.com wrote: I find that View.getWindowToken() always returns null, even when invoked from the main
