getMeasuredHeight() returns 16777215 on Android 4.2.2

Question

I have written a very simple viewgroup extending LinearLayout as below.

 @Override
    protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec) {



        super.onMeasure(widthMeasureSpec, heightMeasureSpec);

        ViewParent viewParent  = getParent();
        if(viewParent instanceof RelativeLayout)
        {
            RelativeLayout parentLayout  = (RelativeLayout)viewParent;

            int widthSize = MeasureSpec.getSize(widthMeasureSpec);


            Log.d(Constants.TAG, "Parent height is " + parentLayout.getMeasuredHeight());
            Log.d(Constants.TAG, "Parent height is1 " + parentLayout.getHeight());
            int height = parentLayout.getMeasuredHeight();
//            getChildAt(0).measure(MeasureSpec.EXACTLY | AndroidUtilities.dp(70), MeasureSpec.EXACTLY | (int)(parentLayout.getMeasuredHeight()*0.6));
 //           getChildAt(1).measure(MeasureSpec.EXACTLY | AndroidUtilities.dp(70), MeasureSpec.EXACTLY | (int)(parentLayout.getMeasuredHeight()*0.4));

            getChildAt(0).measure(MeasureSpec.makeMeasureSpec(AndroidUtilities.dp(70), MeasureSpec.EXACTLY), MeasureSpec.makeMeasureSpec((int)(height* 0.6), MeasureSpec.EXACTLY));
            getChildAt(1).measure(MeasureSpec.makeMeasureSpec(AndroidUtilities.dp(70), MeasureSpec.EXACTLY), MeasureSpec.makeMeasureSpec((int)(height* 0.6), MeasureSpec.EXACTLY));


            setMeasuredDimension(widthSize, parentLayout.getMeasuredHeight());

        }

The parent of this viewgroup is a RelativeLayout containing a simple TextView.

On Android 4.2.2, parentLayout.getMeasuredHeight() returns 16777215. I am not able to make the sense of this number. It is working fine for higher Android versions.

Has anyone encountered this before?

Is this being called before or after the parent layout is attached to the view hierarchy? — Kevin Krumwiede, Mar 02 '15 at 06:32
I am not sure. How do I determine that? This is a view of a list view item — Madhur Ahuja, Mar 02 '15 at 06:34

I haven't seen this, but there's a note in the docs about a bug which fits your scenario:

http://developer.android.com/reference/android/view/View.MeasureSpec.html#makeMeasureSpec(int,%20int)

As for 16777215 (which equals 2^24 - 1), I'm not sure, but it seems like a pretty big coincidence that it's equal to MEASURED_SIZE_MASK. See

http://developer.android.com/reference/android/view/View.html#MEASURED_SIZE_MASK

Thanks. It certainly seems to be that bug. But I am not sure what causes it. What order of argument it is talking about ? – Madhur Ahuja Mar 02 '15 at 06:36

I'm not sure sorry, but you might get something out of this post: [link](http://stackoverflow.com/questions/20147938/android-jelly-bean-measurespec-bug) – peterrhodesdev Mar 02 '15 at 06:47
That is very helpful and is indeed the case I am facing. Thanks. – Madhur Ahuja Mar 02 '15 at 06:51
