title: Customise Android Talkback in Alert Dialogue?
body: <p>I've checked with all default alert dialogue box via Android TalkBack. Default Android Talkback behaviour is that it reads all contents(non stop) in dialogue box. Is there any way I can customise it according to my need. 
  For example : </p>
  
  <pre><code>AlertDialog alertDialog = new AlertDialog.Builder(AlertDialogActivity.this).create();
  alertDialog.setTitle("Alert Dialog");
  alertDialog.setMessage("This is my alert dialog");
  alertDialog.setButton("OK", new DialogInterface.OnClickListener() {
      public void onClick(DialogInterface dialog, int which) {
          Toast.makeText(getApplicationContext(), "You clicked on OK", Toast.LENGTH_SHORT).show();
      }
  });
  
  alertDialog.show();
  </code></pre>
  
  <p>When dialog appears, it reads automatically "Alert Dialogue. This is my alert dialogue. OK." But I want to control it, like it should read only "Alert Dialogue" or "This is my alert dialogue" etc.</p>
  
  <p>And while tapping on "OK" it reads only "OK", instead "OK button".</p>
