android开发之EditText默认hint字体大小

直接看代码

String hintStr = "请输入相关信息";
        SpannableString ss = new SpannableString(hintStr);
        AbsoluteSizeSpan ass = new AbsoluteSizeSpan(14, true);
        ss.setSpan(ass, 0, ss.length(), Spanned.SPAN_EXCLUSIVE_EXCLUSIVE);
        leaveLong.setHint(new SpannedString(ss));
