help me guys task 1 to task 3, completely confused by ben deitch, cant figure out what he wants , thank you in advance

Challenge Task 1 of 3 We're currently creating a new Thread each time we want to update our Twitter app. Instead, let's now use a Handler. Start by creating a new inner class extending Handler, and move the call to 'twitterClient.update()' into this new Handler's 'handleMessage' method.

MainActivity.java 
public class MainActivity extends Activity {
  Button button;
  TwitterClient twitterClient = new TwitterClient();

  @Override
  public void onCreate(Bundle savedInstanceState) {
    setContentView(R.layout.activity_main);

    final TwitterThread twitterThread = new TwitterThread();
    twitterThread.setName("TwitterThread");
    twitterThread.start();

    button = (Button) findViewById(R.id.update_button);
    button.setOnClickListener(new View.OnClickListener() {
      @Override
      public void onClick(View v){

      }
    });
  }

  class TwitterThread extends Thread {
    @Override
    public void run() {
      twitterClient.update();
    }
  }
}

Hi Ted. We need to do exactly the same thing as we did in the video (except that we're creating an inner class and not a separate class):

  • Create an inner class (name of your choice) that extends Handler
  • Override the handleMessage() method inside that class
  • Move the twitterClient.update() method inside that handleMessage() method

Hope that helps :)
