Question

String[] datesReason = {
            "New Years Day",
            "Martin Luther King, Jr.'s Birthday",
            "Asian Lunar New Year"
};
public String[] suspendedDates = {
            "Friday, January 1",
            "Monday, January 18",
            "Saturday, March 5"
};

DateFormat df = new SimpleDateFormat("EEEEE, LLLL d", Locale.US);

Spannable WordToSpan = new SpannableString("Today is: ");
WordToSpan.setSpan(new ForegroundColorSpan(R.color.dateholiday), 0, WordToSpan.length(), Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);
tvTD.setText(WordToSpan);

Spannable WordToSpan1 = new SpannableString("" + df.format(new Date()) + "");
WordToSpan1.setSpan(new ForegroundColorSpan(Color.parseColor("#4787ED")), 0, WordToSpan1.length(), Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);
tvTD.append(WordToSpan1);

当我从PC调试到Android模拟器时，上面的代码显示Today is: Saturday, March 5。当我使用Android设备调试（运行Lollipop，Jellybean等）时，它会显示Today is: S, March 5

我也使用上面的内容来比较当天做其他功能的日期，我有以下内容，将日期与今天进行比较：

SetRows myImage = data.get(position); //SetRows is what I am using to populate a ListView with texts/images
int inReason = myImage.name.indexOf(",");
String strR = myImage.name.substring(0, inReason);
Spannable WordToSpan = new SpannableString(strR); //e.g. strR = "Saturday"
WordToSpan.setSpan(new ForegroundColorSpan(Color.parseColor("#4787ED")), 0, WordToSpan.length(), Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);
String strRNext = myImage.name.substring(inReason, myImage.name.length());
Spannable WordToSpan1 = new SpannableString(strRNext); //e.g. strRNext = "March 5"
WordToSpan1.setSpan(new ForegroundColorSpan(R.color.dateholiday), 0, WordToSpan1.length(), Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);

if (myImage.name.contains(df.format(Calendar.getInstance(Locale.US).getTime()))) { //if Today is Saturday, March 5, the set the background of the list item...
   Toast.makeText(getContext(), String.valueOf(myImage.name.contains(df.format(Calendar.getInstance(Locale.US).getTime()))), 2000).show();
   row.setBackgroundColor(Color.parseColor("#F0DEEDF3"));
}
else { //otherwise use the default background...
   row.setBackgroundColor(Color.parseColor("#CCF5F5F5"));
}

在模拟器中，正确的列表项将获得背景，但在手机中，它不会，因为它显示S而不是Saturday

知道为什么会这样，我该如何解决呢。

来自documentation：

每周的E日（文字）E / EE / EEE：周二，EEEE：周二，EEEEE：T

您正在使用＆＃34; EEEEE＆＃34;这将只显示第一个字母，因此您需要删除一个E＆＃39; E＆＃39;如果你想展示一整天。

为什么模拟器和手机中的显示效果不一样
