title: How to display two numbers in minute in android
body: <p>I´m trying to display the "two numbers" of minute in my code with an Android TimePicker. But I didn´t get it yet...  The time is only displayed in this format X:X. For example 9:05 will show in my app 9:5.</p>
  
  <p>Can anyone help me please?</p>
  
  <p>This is my code...</p>
  
  <pre><code>idtime.setText(new StringBuilder()
           .append(String.valueOf(mHour)).append(":")
           .append(String.valueOf(mMinute)).toString());
  </code></pre>
