title: How to show soft keyboard on Android Things?
body: <p>I'm trying to show soft keyboard on <em>Android Things</em>, <em>Raspberry Pi 3</em>. I tried the methods below, but not succeeded so far:</p>
  
  <pre><code>&lt;activity
         ...
         android:windowSoftInputMode="stateAlwaysVisible"&gt;
  </code></pre>
  
  <p>and</p>
  
  <pre><code>&lt;EditText
          ...
          android:inputType="numberDecimal"/&gt;
  </code></pre>
  
  <p>Does <em>Android Things</em> 7.0 support soft keyboard, or am I missing something? </p>
