How to keep the spaces at the end and/or at the beginning of a String?
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>
I do it this way :
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();
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) ...
What should I do ?
I guess the answer is somewhere here in this documentation link
or is it something like using & ; for the "&" character ??
Solution 1:
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.
Use   for non-breakable whitespace.
Use   for regular space.
Solution 2:
I ran into the same issue. I wanted to leave a blank at the end of a resource string representing an on-screen field name.
I found a solution on this issue report : https://github.com/iBotPeaches/Apktool/issues/124
This is the same idea that Duessi suggests. Insert \u0020 directly in the XML for a blank you would like to preserve.
Example :
<string name="your_id">Score :\u0020</string>
The replacement is done at build time, therefore it will not affect the performance of your game.
Solution 3:
This documentation suggests quoting will work:
<string name="my_str_spaces">" Before and after? "</string>
