  private List&lt;Integer&gt; list;
  @Override
  public void onCreate(Bundle savedInstanceState) {
    (savedInstanceState);
    setContentView();
    sb = new StringBuffer();
    list = new ArrayList&lt;Integer&gt;();
    textView = (TextView) findViewById();
    for (int i = 0; i &lt; (); i++) {
      if (matcherReg(((i)))) {
        (i);
      }
    }
    SpannableStringBuilder style=new SpannableStringBuilder(tempStr);
    for (int i = 0; i &lt; (); i++) {
      ((i)+", ");
// (new BackgroundColorSpan(),(i),(i)+1,Spannable.SPAN_EXCLUSIVE_INCLUSIVE); //Set the background color of the specified location textview      (new ForegroundColorSpan(),(i),(i)+1,Spannable.SPAN_EXCLUSIVE_INCLUSIVE);   //Set the color of the text at the specified location    }
    (style); 
  }
  private boolean matcherReg(CharSequence c){
    String regEx="[^0-9]";  
    Pattern p = (regEx);  
    Matcher m = (());  
    if (()) {
      return false;
    }
