title: add read more TextView on another TextView android
body: <p>I want to add a simply "Read more" / "Read less" Button on an existing TextView combinating another..</p>
  
  <p>I did this:</p>
  
  <pre><code> this.announcer_description = (TextView) findViewById(R.id.announcer_description);
      this.readmore = (TextView) findViewById(R.id.readmore);
      this.readmore.setOnClickListener(new OnClickListener() {
              public void onClick(View v) {
                  if (readmore.getText().equals("Read More"))
                  {
                      announcer_description.setText("");
                      announcer_description.setText(currentAnnouncer.getDescription_fr());
                      readmore.setText("");
                      readmore.append("Read less");
                  }
                  else if (readmore.getText().equals("Read less"))
                  {
                      announcer_description.setText("");
                      announcer_description.setText(shortDesc);
                      readmore.setText("");
                      readmore.append("Read more");
                  }
              }});
  </code></pre>
  
  <p>My "announcer_description" TextView is initialize to "Read more".. but this doesn't work..
  The only way I found using Read more and Read Less is to nest some many OnClickListener in this OnClickListener..</p>
  
  <p>Someone does have an idea?</p>
