ImageView, why different size?
<p>First thing, I know many people have asked same thing, but this one is nearly same but I have few more questions.</p>

<p>I have an image of 48px x 48px, so if I set this image in ImageView with     </p>

<pre><code>layout_width="wrap_content"
layout_height="wrap_content"
</code></pre>

<p>then image looks bigger but if I use following fixed size, it gets smaller</p>

<pre><code>layout_width="48dp"
layout_height="48dp"
</code></pre>

<p>I think it's now showing properly(not pixelated ?) with 48dp, but why it got bigger if I use wrap_content ? And if the image size through wrap_content is correct then whats the point of using dp(if it make image smaller) ?</p>
