title: android setText with getString using variable name
body: <p>So, searching the internet I found many examples that were not what I need...</p>
  
  <p>Here is my situation:</p>
  
  <p>Imagine that you have a resource that is an array called songs and many 's with each song name..so, imagina you have like 200 song names displayed on a listview..</p>
  
  <p>when you click a song, the app loads another activity with the lyrics for that song...
  but HOW do you do that?</p>
  
  <p>Here is how I did it.. I passed the name of the song to this new activity, loaded the resource where the lyrics are...</p>
  
  <p>BUT, at the time I have to setText with the lyrics, I got a problem... should I do a switch with 200 cases? that sounds insane, so, what I did was, I used the same name of the song to the lyrics..so it should load like this:</p>
  
  <pre><code>TextView txtProduct = (TextView) findViewById(R.id.product_label);
  
      Intent i = getIntent();
      // getting attached intent data
      String[] musicas = getResources().getStringArray(R.array.botafogo_songs);
      // this here is where it brings the name of the music to the activity
      String product = i.getStringExtra("product");
      // displaying selected product name
      if (Arrays.asList(musicas).contains(product)) {
              //just formating so they have the same name.
          String productSplit = product.split("- ")[1];
          productSplit.replace(" ", "");
          txtProduct.setText(getString(R.string.AbreAlas)); 
      }else{
          txtProduct.setText("não contem");
      }
  </code></pre>
  
  <p>Ok, AbreAlas is the name of my resource..it loads fine..
  BUT, I cant leave it like this...it should be a variable name...
  like: <code>R.string.+productSplit</code>
  or something like this..</p>
  
  <p>I can't find the solution nowhere..</p>
