1.只贴代码,不解释,留作以后用/** * @param tv Display a message that include title and content * @param title Title of message * @param content Content of message * @param titleColorID The color id for Title * @param contentColorID The color id for Content */ public static void colorForTextView(Context context, TextView tv, String title, String content, int titleColorID, int contentColorID) { if (content == null) { content = ""; } SpannableStringBuilder spannableBuilder = new SpannableStringBuilder(); ForegroundColorSpan titleColorSpan = new ForegroundColorSpan(ContextCompat.getColor(context, titleColorID)); ForegroundColorSpan contentColorSpan = new ForegroundColorSpan(ContextCompat.getColor(context, contentColorID)); spannableBuilder.append(title); int temp = spannableBuilder.length(); spannableBuilder.setSpan(titleColorSpan, 0, temp, Spanned.SPAN_INCLUSIVE_INCLUSIVE); spannableBuilder.append(content); spannableBuilder.setSpan(contentColorSpan, temp, spannableBuilder.length(), Spanned.SPAN_EXCLUSIVE_INCLUSIVE); tv.setText(spannableBuilder, TextView.BufferType.SPANNABLE); }
