In some cases, determining the height for both Status and Title Bar is necessary. Using Window.getDecorView().getWindowVisibleDisplayFrame(...), I was able to find the height for both:
code snippet
Rect rect= new Rect();
Window window= activity.getWindow();
window.getDecorView().getWindowVisibleDisplayFrame(rect);
int statusBarHeight= rect.top;
int contentViewTop=
window.findViewById(Window.ID_ANDROID_CONTENT).getTop();
int titleBarHeight= contentViewTop - statusBarHeight;
It's really great to see this article!!
ReplyDeleteBut... it seem doesn't work for me...
according to your code, both statusBarHeight and titleBarHeight get zero.
Have any idea??
Thanks a lot!!
Yes, I know why. The method View.getWindowVisibleDisplayFrame(...) will only return coords when the view is attached to a Window. Otherwise, it returns the raw display size, causing statusBarHeight to be 0. I called the above code from within a Dialog, hence, the decorView was attached to a Window. Try something like the following, assuming you are in Activity.onCreate(...), with a view from your layout (i.e. mapView):
ReplyDeletelayoutView1.post(new Runnable()
{
public void run()
{
Rect rect= new Rect();
Window window= getWindow(); layoutView1.getWindowVisibleDisplayFrame(rect);
int statusBarHeight= rect.top;
int contentViewTop= window.findViewById(Window.ID_ANDROID_CONTENT).getTop();
int titleBarHeight= contentViewTop - statusBarHeight;
}
});
This is grate idea : )
