Android - Height of title bar

Question

I want to get the title bar height (not the status bar)

I need this in order to know the real height the app can use.

I saw on SO some code and I tried it and it returned height=0.

So, I did some more search and I found that I have to put it inside a runnable and call it with a post-delayed.

Here is the code:

    Handler mHandler = new Handler();

    Runnable r = new Runnable() {  
        @Override  
        public void run() {  
            Rect frame = new Rect();  
            getWindow().getDecorView().getWindowVisibleDisplayFrame(frame);  
            int titleHeight = frame.top;  
            Log.d(TAG, titleHeight); 
        }  
    };  

    mHandler.postDelayed (r, 200);

This is working. The Log.D shows the correct height, But now there is a new problem. I cannot use the titleHeight variable for further programming inside my onCreate.

What to do?

Thanks, AJ

The scope of that variable is inside the run method. If you want to reference that variable, you should change it to a larger scope (define it outside of this method).

I did. But outside the runnable, the variable is zero! and not the real calculated height... – AJ Gottes Nov 18 '14 at 23:36
this is because is postDelayed – rnrneverdies Nov 18 '14 at 23:36
You still need to set the value of the variable, but it needs to be scoped outside that method to access it elsewhere. – Booger Nov 18 '14 at 23:37
@Deuterium, so what it the solution to be possible to use it outside of the runnable? I already defined it outside of the runnable. – AJ Gottes Nov 18 '14 at 23:43
@Deuterium, the other question suggest using known title heights. I want to calculate it. – AJ Gottes Nov 18 '14 at 23:49
@AJGottes why calculate a fixed height? – rnrneverdies Nov 18 '14 at 23:50
