title: How to add text to editext
body: <p>I've got a problem with populating an edittext. Using the following code i can set the text just fine, however what i am trying to do is add to the edittext. For example the following code displays a "1" in my edittext but if I press it again it just replaces the "1" with "1" and so on. What i need is it to display "1111" if I press it four times.</p>
  
  <p>heres my code:</p>
  
  <pre><code>@Override
      public void onClick(View v) {
          switch (v.getId()) {
                      case R.id.button1:
  
                          Button txtnum = (Button) findViewById(R.id.button1);
  
                          Bundle bundle = new Bundle();
                          bundle.putString("number1", txtnum.getText().toString());
                          String title = bundle.getString("number1");
                          ((EditText) findViewById(R.id.editText1)).setText(title);
  
  
  
                          break;
  </code></pre>
  
  <p>Hope this makes sence. (I'm a noob)
  If anyone can help me with this I'd really appreciate it.
  thanks Steve</p>
