    <p>The <a href="http://developer.android.com/reference/android/view/View.html#SizePaddingMargins" rel="noreferrer">Android Documentation says</a> that there is two sizes for a view, the <em>measured dimensions</em> and the <em>drawing dimensions</em>. The measured dimension is the one computed in the <em>measure pass</em> (the <a href="http://developer.android.com/reference/android/view/View.html#onMeasure%28int,%20int%29" rel="noreferrer">onMeasure</a> method), while the <em>drawing dimensions</em> are the actual size on screen. Particularly, the documentation says that:</p> <blockquote> <p>These values may, but do not have to, be different from the measured width and height.</p> </blockquote> <p>So, my question is: what could make the drawing dimension be different of the measured dimension? If the <a href="http://developer.android.com/reference/android/view/View.html#onMeasure%28int,%20int%29" rel="noreferrer">onMeasure(int,int)</a> method respects the layout requirements (given as the parameters <em>widthMeasureSpec</em> and <em>heightMeasureSpec</em>, how could the SDK decides that the view should have a different drawing size?</p> <p>Additionally, how/where in the <a href="https://github.com/android" rel="noreferrer">Android Source Code</a> the measured width/height is used to compute the drawing width/height? I tryed to look into the <a href="https://github.com/android/platform_frameworks_base/blob/master/core/java/android/view/View.java" rel="noreferrer">View source code</a>, but I can't figure out how the measuredWidth/Height is used to compute the final width/height. Maybe it has something to do with the padding, but I'm not sure.</p>

    1. COI think that these measures can be different in case if a scroll is added to the view.

    2. COMaybe, but I developed a custom ViewGroup, and this is happening in my code. I am not dealing with scroll until the point where this behavior occurs. So I think that there should be more than scroll involved into this.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
