negative number within RTL AlertDialog

Question

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...

Answer 1

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>
