Required Output

我尝试修改代码，但没有得到预期的结果。

我的代码:

public void setCompulsoryAsterisk() {
    txt_name="Name : ";
    String colored="*";
    SpannableStringBuilder strBuilder=new SpannableStringBuilder();
    strBuilder.append(txt_name);
    int start=strBuilder.length();
    strBuilder.append(colored);
    int end=strBuilder.length();
    strBuilder.setSpan(new ForegroundColorSpan(Color.RED), start, end, Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);
    txtName.setText(strBuilder);
}

尝试这样的事情:

string = "<font color='#000000'>Name </font>" + "<font color='#FF0000'>*</font>" + "<font color='#000000'>:</font>";
textView.setText(Html.fromHtml(string));
