如何在字符串的末尾和/或开头保留空格? [英] How to keep the spaces at the end and/or at the beginning of a String?

问题描述

我必须将我的资源/值文件中的这两个字符串连接起来:

I have to concatenate these two strings from my resource/value files:

<string name="Toast_Memory_GameWon_part1">you found ALL PAIRS ! on </string>
<string name="Toast_Memory_GameWon_part2"> flips !</string>

我这样做:

String message_all_pairs_found = getString(R.string.Toast_Memory_GameWon_part1)+total_flips+getString(R.string.Toast_Memory_GameWon_part2);

Toast.makeText(this, message_all_pairs_found, 1000).show();

但是第一个字符串末尾和第二个字符串开头的空格 已经消失了(显示Toast时)...

But the spaces at the end of the first string and at the beginning of the second string have disappeared (when the Toast is shown) ...

我该怎么办?

我猜答案在此文档中的某处链接

还是类似于对<&>使用 &amp ; 字符??

or is it something like using &amp ; for the "&" character ??

推荐答案

即使您使用字符串格式设置，有时您仍然需要在字符串的开头或结尾使用空格.对于这些情况，使用\转义和xml:space属性都无济于事.您必须将HTML实体 用于空白.

Even if you use string formatting, sometimes you still need white spaces at the beginning or the end of your string. For these cases, neither escaping with \, nor xml:space attribute helps. You must use HTML entity   for a whitespace.

将 用于不可中断的空白.
将 用于常规空间.

Use   for non-breakable whitespace.
Use   for regular space.
