negative number within RTL AlertDialog

1

using the following resource:

ltr: <string name="err_field_range_hint_f">Possible values: [%1$.0f .. %2$.0f]</string> 
rtl: <string name="err_field_range_hint_f">ערכים אפשריים:
 [%2$.0f .. %1$.0f]</string> 

in the following code:

 _AlertDialog = new AlertDialog.Builder(this).
 setTitle(getString(R.string.title)) 
 .setMessage(getString(R.string.err_field_range_hint_f, valLow, valHigh) ) 
 .setPositiveButton(getString(R.string.ok), null)
 .show();

I receive [25- .. 100] instead of [-25 .. 100]

I solved similiar problem in the layout with forcing LTR in EditText fields, using:

android:inputType="numberSigned|numberDecimal" 
android:textDirection="ltr"

but how can I force LTR on specific "words" (or numbers) inside AlertDialog.Message?

Note: I saw a solution in here but I prefer android would handle formatting numbers...

I am not sure you want to receive

and not

At any rate, the easiest fix is to insert the Unicode BIDI override markers, e.g. LRO:

<string name="err_field_range_hint_f">ערכים אפשריים:
 u202D[%2$.0f .. %1$.0f]u202C;</string>

  If you ask about uXXXX vs. U+XXXX – these are simply different notations. The former is supported in Android XML. Maybe you can use other notations, too.

  As for the behaviour of different Unicode markers, Left-to-Right Mark (LRM) u200E is an invisible character that is equivalent to letter A. It does not change the 'paragraph order', or android:textDirection of the text field. The LRO character starts a 'span' that is almost like android:textDirection="ltr" within the text field.

You can find the "message" text view inside the alert dialog, and than apply the same method you used on your edit text to correct the LTR issue.

Consider this SO answer to find the inner text view:
