title: Import and use android wheel as number picker
body: <p>I have a question with this project <a href="https://github.com/sephiroth74/AndroidWheel" rel="nofollow">https://github.com/sephiroth74/AndroidWheel</a> .. I have found more questions like this but its answers were not that i expected. The thing is that I cloned it to Eclipse by using IMPORT -> Clone GIT. Then i clicked project properties and ticked "Is Library" checkbox, so I went to my project, click add, and when androidwheel was selected a lot of errors appeared in my projects. Errors said this:</p>
  
  <pre><code>    R cannot be resolved to a variable
  </code></pre>
  
  <p>I managed to use devmilcolor library  with my project, so i dont know where is my error :(</p>
  
  <p>I have to say that import android.R is not used!</p>
  
  <p>Please help to identify my problem :)</p>
