StringTokenizer变量分隔符

我想制作一个用特殊符号和数字着色单词的function。 这样的事情：如果用户输入^2Hi ^3everyone! Hi = green . everyone = red. ^2Hi ^3everyone! Hi = green . everyone = red. 但仅当符号"^x"存在时，（x =指定颜色的数字）。

然后我想用textview和html格式来设置颜色。

像这样的东西：

 int x;   TextView show = (TextView)findViewById(R.id.show); //gen is my button to print the result in the textview gen.setOnClickListener(new View.OnClickListener() {  public void onClick(View v) {    String txt = tv.getText().toString();    //"+x+ doesnt work :s here i want to pu a int x between 0 and 9    StringTokenizer tokenizer = new StringTokenizer(txt,"^"+x+);        switch(x) {    case 1:    s = "red";    break;    case 2:    s = "green";    break;    default:    s = "white";    }        show.setttext(function to set text in html format)  } } 

抱歉，但我不明白要正确发布代码：谢谢:)’
