title: Custom Elements images are blurry Android
body: <p>I'm having some issues creating custom elements in Android layout.
  I have a <code>CheckBox</code> and an <code>EditText</code>, I've created a custom <code>CheckBox</code> image (for state ON and OFF) and a custom LeftView image for my <code>EditText</code>, the size of the images I've created is the same of the checkboxes but when I run the app the images are blurry and low-quality.</p>
  
  <p>To set the <code>EditText's</code> LeftView I used:</p>
  
  <pre><code> android:drawableLeft="@drawable/user_icon"
  </code></pre>
  
  <p>And for the custom <code>CheckBox</code> image I used:</p>
  
  <pre><code>&lt;?xml version="1.0" encoding="utf-8"?&gt;
      &lt;selector xmlns:android="http://schemas.android.com/apk/res/android"&gt;
           &lt;item android:state_checked="true" android:drawable="@drawable/check_on" /&gt;
           &lt;item android:state_checked="false" android:drawable="@drawable/check_off" /&gt;
      &lt;/selector&gt;
  </code></pre>
  
  <p>Am I missing something? I can't create larger images because the elements size will just resize to the content and if I set it to be lower than the image size the image will get cut out (from top and bottom)</p>
