title: Disable SPACE key in EditText android
body: <p>I'd created EditText with following. </p>
  
  <pre><code>&lt;EditText
          android:id="@+id/et_regis_num"
          android:maxLines="1"
          android:layout_width="match_parent"
          android:layout_height="wrap_content"
          android:digits="1234567890ABCDEFGHIJKLMNOPQRSTUVWXYZ"
          android:hint="@string/txt_reg_num"
          android:inputType="textCapCharacters"
          android:maxLength="10" /&gt;
  </code></pre>
  
  <p>in this edittext I don't want to press SPACE key but when I'm pressing SPACE key it's working as BACKSPACE key. means it's deleting one character in each twice press.</p>
