Getting the height of an inflated Linearlayout at runtime

Question

I am trying to calculate the height of a linear layout after it is being inflated. However, every time the size returned is zero. Am I doing something wrong here?

The code is given below:

LayoutInflater layoutInflater = (LayoutInflater) getActivity()
            .getSystemService(Context.LAYOUT_INFLATER_SERVICE);
    mObjectActionsBar = (LinearLayout) layoutInflater
            .inflate(R.layout.object_actions_bar, null);
    mToolbarHeight = (float) mObjectActionsBar.getHeight();
    mObjectActionsBar.setVisibility(View.GONE);
    mWorkbenchFrame.addView(mObjectActionsBar);

Please help me in figuring out what the problem is here.

Missed to mention these. mWorkbenchFrame is a FrameLayout. This code is in the onCreateView of a Fragment class. — Vivek, Jan 12 '12 at 09:39

You can not calculate height of any view, unless it is drawn on the screen, so you need to use observer in this case:

LayoutInflater layoutInflater = (LayoutInflater) getActivity()
            .getSystemService(Context.LAYOUT_INFLATER_SERVICE);
mObjectActionsBar = (LinearLayout) layoutInflater
            .inflate(R.layout.object_actions_bar, null);
ViewTreeObserver observer = mObjectActionsBar .getViewTreeObserver();
observer.addOnGlobalLayoutListener(new OnGlobalLayoutListener() {
    @Override
    public void onGlobalLayout() {
        //in here, place the code that requires you to know the dimensions.
         mToolbarHeight = (float) mObjectActionsBar.getHeight();
        //this will be called as the layout is finished, prior to displaying.
    }
}

mObjectActionsBar.setVisibility(View.GONE);
mWorkbenchFrame.addView(mObjectActionsBar);

Sorry this did not work for me. It still returns zero. :( – Vivek Jan 12 '12 at 10:29 — Vivek, Jan 12 '12 at 10:29
