I am using the following code to dynamically hide the TitleBar:
ViewGroup ob = (ViewGroup)
findViewById(android.R.id.title).getParent();
((View)ob).setVisibility(View.INVISIBLE);
ob.setLayoutParams(new LinearLayout.LayoutParams(0, 0));
getWindow().addFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN);
getWindow().clearFlags(WindowManager.LayoutParams.FLAG_FORCE_NOT_FULLSCREEN);
findViewById(android.R.id.content).getRootView().requestLayout();
I am then using the following code to dynamically show the TitleBar:
ViewGroup ob = (ViewGroup)
findViewById(android.R.id.title).getParent();
((View) ob).setLayoutParams(new
LinearLayout.LayoutParams(LayoutParams.FILL_PARENT,
LayoutParams.WRAP_CONTENT));
((View)ob).setVisibility(View.VISIBLE);
getWindow().addFlags(WindowManager.LayoutParams.FLAG_FORCE_NOT_FULLSCREEN);
getWindow().clearFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN);
findViewById(android.R.id.content).getRootView().requestLayout();
This code works on the emulator (using 2.2 and 4.0.3) as well as on a
device (Motorola Droid running Cyanogenmod 7) with no problems.
I'm nervous though about using the android.R.id.title in such a way since
there is no documentation on the title field in android.R.id. Also, all the
questions/answers/blog posts I found on the internet say that there is now
way to dynamically remove the title bar after setContentView is called; so
I'm assuming the method I'm using above is incorrect in some way.
Is what I am doing safe?
Thanks,
Vance
