    <p>I have defined a custom view, as a Java class, and now I want to put them in a layout, programmatically.</p> <p>I can define a layout structure like this :</p> <pre><code>&lt;LinearLayout&gt; &lt;!-- vertical, main container --&gt; &lt;LinearLayout&gt; &lt;!-- 1st horizontal (consists of 2 columns (items) ) --&gt; &lt;CustomView /&gt; &lt;!-- 1 --&gt; &lt;CustomView /&gt; &lt;!-- 2 --&gt; &lt;/LinearLayout&gt; &lt;LinearLayout&gt; &lt;!-- 2nd horizontal (consists of 2 columns (items) ) --&gt; &lt;CustomView /&gt; &lt;!-- 1 --&gt; &lt;CustomView /&gt; &lt;!-- 2 --&gt; &lt;/LinearLayout&gt; &lt;!-- ..... --&gt; &lt;LinearLayout&gt; &lt;!-- nth horizontal (consists of n columns (items) ) --&gt; &lt;CustomView /&gt; &lt;!-- 1 --&gt; &lt;CustomView /&gt; &lt;!-- 2 --&gt; &lt;/LinearLayout&gt; &lt;/LinearLayout&gt;&lt;!-- vertical container --&gt; </code></pre> <p>but when I delete one of the custom views, it remains ugly. Suppose n=3 and I removed custom view number 4. I have :</p> <pre><code>1 2 3 5 6 </code></pre> <p>which does not look good, they should "fill the leading space" like this:</p> <pre><code>1 2 3 5 6 </code></pre> <p>How should I achieve such a thing?</p> <p>And please note that I construct the <code>CustomView</code>s in Java code (not in XML)</p> <p>I have tried getting the screen size, dividing it by n, and assign the value as the <code>LayoutParams.width</code> of the custom view.</p> <p>But getting the screen size in dp's is not a very accurate thing, according to some questions in StackOverflow.</p> <p>So how should I create a grid layout programmatically ?</p>

    1. COHave you considered using a `GridView`? That does everything you describe here. If you have, then perhaps you could elaborate on why you dismissed it, so we better understand your intentions. Also, `2 x 3 != n x n`. ;)

    2. COI thought that GridView was added in a later API Level. omg is this API Level 1 ? and yes, you are right, I formulized it wrong :) I'm actually trying to create an nx2 grid. Updated the question. hope it is right now :)

    3. COYou may be confusing `GridLayout` and `GridView`. The former was originally added with ICS, but is now also available for API level 7+ thanks to the support library (v7). Anyways, I'm babbling, because you're probably going to be interested in `GridView` more.

Guidance
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.
