title: Unable to input negative sign in EditText created programmatically
body: <p>I create an EditText programmatically using these lines of code:</p>
  
  <pre><code>ContextThemeWrapper mContextThemeWrapper = new ContextThemeWrapper(context, R.style.AppTheme);
  EditText mEditText = new EditText(mContextThemeWrapper);
  mEditText.setInputType(InputType.TYPE_CLASS_NUMBER | InputType.TYPE_NUMBER_FLAG_DECIMAL | InputType.TYPE_NUMBER_FLAG_SIGNED);
  </code></pre>
  
  <p>The keyboard that shows when I focus on the input is the following:</p>
  
  <p><a href="https://i.stack.imgur.com/BNTdr.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/BNTdr.png" alt="enter image description here"></a></p>
  
  <p>However, I am unable to select the "<strong>-</strong>" sign. I've tried pressing once, twice, holding, and the button always inputs a "<strong>.</strong>".</p>
  
  <p>Any ideas on how to input the minus sign before my negative number?</p>
  
  <p><strong>Edit 1</strong>
  Apparently the problem is with the device I need to use. I'm using a Samsung Tablet E with Android 4.4.4.
  Testing the same EditText on a different device worked as expected, but I need to run on the tablet. </p>
