title: Android set android:state_checked="false" in code
body: <p>I want to create a selector using the code below:</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/sh_radio_icon_checked" /&gt;
      &lt;item android:state_checked="false" android:drawable="@drawable/sh_radio_icon_unchecked" /&gt;
  &lt;/selector&gt;
  </code></pre>
  
  <p>So far I have managed to add the first item, like this:</p>
  
  <pre><code>StateListDrawable drawable = new StateListDrawable();
  int[] sFocusedSelected = {android.R.attr.state_checked};
  Drawable dFocusedSelected = getResources().getDrawable(R.drawable.sh_radio_icon_checked);
  drawable.addState(sFocusedSelected, dFocusedSelected);
  </code></pre>
  
  <p>But do I add the state_checked=false since there's no state_unchecked constant?</p>
