title: TextView + variable
body: <p>I've added to my TextView, after it has been modified with set.Text, a variable of type int (CONT1) 
  How do I change only the color of the variable cont1? 
  part of my code:</p>
  
  <pre><code>TextView cpu=(TextView) findViewById(R.id.cpu);
  cpu.setText("CPU: " + cont1);
  </code></pre>
  
  <p>I tried to put the value of cont1 in a new TextView and then add it to the first TextView in this way:</p>
  
  <pre><code>TextView cpu=(TextView) findViewById(R.id.cpu);
  TextView color=new TextView(this);
  color.setText(cont1);
  color.setTextColor(220);
  cpu.setText("CPU: " + color);
  </code></pre>
  
  <p>but the output gives me strange values,how can I do to change only the color of the variable CONT1?</p>
  
  <p>the problem is that I'm not merge two TextView</p>
  
  <p>cpu.setText("CPU: " + color);
  this code no work ,Why can not I merge two TextView?</p>
