title: force textview to show numbers with only english digits
body: <p>I use below code to force my textview to show its text numbers with English digits:</p>
  
  <pre><code>txtScale.setText("x" + String.format(Locale.ENGLISH, String.valueOf(scaleValue)));
  </code></pre>
  
  <p>but it is not working and keep showing the numbers with selected locale. If application locale set to Arabic, it show numbers to Arabic, if set to English it show them English but I want to force to show numbers in English at all states.</p>
  
  <p>For example I want to show below text in Arabic:</p>
  
  <pre><code>۱۲۳۴ //are one two three four
  </code></pre>
  
  <p>As:</p>
  
  <pre><code>1234
  </code></pre>
  
  <p>If it helps, I use below code for changing the language of the app manually:</p>
  
  <pre><code>    Locale locale = new Locale(CurrentLanguage);
      Locale.setDefault(locale);
      Configuration config = new Configuration();
      config.locale = locale;
      context.getResources().updateConfiguration(config,
              context.getResources().getDisplayMetrics());
  </code></pre>
