TextView设置 多种颜色，封装好的工具类

/**
* textview设置2种颜色
*/
public static void textViewShowTwoColor(TextView textView, String oneStr, String twoStr, String oneColor, String twoColor) {
String focus_content = oneStr + twoStr;

SpannableStringBuilder builder = new SpannableStringBuilder(focus_content.toString());
ForegroundColorSpan redSpan = new ForegroundColorSpan( Color.parseColor(oneColor));
ForegroundColorSpan whiteSpan = new ForegroundColorSpan(Color.parseColor(twoColor));

builder.setSpan(redSpan, 0, oneStr.length(),Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);
builder.setSpan(whiteSpan, oneStr.length(), focus_content.length(), Spannable.SPAN_INCLUSIVE_INCLUSIVE);
textView.setText(builder);
}

其他的有需要，可以 根据我上面的改动
