title: Android disable space only for Edittext
body: <p>In my android application I need to disABLE  Spacebar only. But I didn't find a solution for this problem. I need to disable space bar and when user enter space should not work, special characters, letters, digits and all other should work. What I tried is,</p>
  
  <pre><code>etPass.addTextChangedListener(new TextWatcher() {
  
              @Override
              public void onTextChanged(CharSequence s, int start, int before, int count) {
                  // TODO Auto-generated method stub
                  String str = s.toString();
                  if(str.length() &gt; 0 &amp;&amp; str.contains(" "))
                  {
                      etPass.setError("Space is not allowed");
                      etPass.setText("");
                  }
              }
  
              @Override
              public void beforeTextChanged(CharSequence s, int start, int count,
                                            int after) {
                  // TODO Auto-generated method stub
  
              }
  
              @Override
              public void afterTextChanged(Editable s) {
                  // TODO Auto-generated method stub
  
              }
          });
  </code></pre>
  
  <p>But the problem here is once space comes whole text is deleting. I removed </p>
  
  <pre><code>etPass.setText("");
  </code></pre>
  
  <p>this line, so at that time error message is showing, but at that time user can still able to type space. But what I need is user shouldn't able to type the space.</p>
