title: How can I make my button to do something in Fragments,ViewPager
body: <p>First I must say that I'm not good at English and "completely new" to Android Programming.</p>
  
  <p>I want to create an app like Android's home screen which can slide left-right to see the views. On my app, each view will have a button to do something; Now I have accomplished the sliding part by using ViewPager and Fragments. When I run my app, it can smoothly go left-right views but I can't find the solution to make a button in each view to working. How can I do this? Thank you very much for every of your answers. Followings are my code(I modified it from examples over the internet).</p>
  
  <p>This the main fragment class that contains many fragments in it.</p>
  
  <pre><code>public class LessonsActivity extends FragmentActivity{
  /** maintains the pager adapter */
  private PagerAdapter mPagerAdapter;
  
  /*
   * (non-Javadoc)
   * 
   * @see android.support.v4.app.FragmentActivity#onCreate(android.os.Bundle)
   */
  @Override
  protected void onCreate(Bundle savedInstanceState) {
      super.onCreate(savedInstanceState);
      super.setContentView(R.layout.viewpager_layout);
      // initialsie the pager
      this.initialisePaging();
  }
  
  /**
   * Initialise the fragments to be paged
   */
  private void initialisePaging() {
  
      List&lt;Fragment&gt; fragments = new Vector&lt;Fragment&gt;();
      fragments.add(Fragment.instantiate(this, Lesson_1.class.getName()));
      fragments.add(Fragment.instantiate(this, Lesson_2.class.getName()));
      fragments.add(Fragment.instantiate(this, Lesson_3.class.getName()));
      fragments.add(Fragment.instantiate(this, Lesson_4.class.getName()));
      this.mPagerAdapter = new PagerAdapter(
              super.getSupportFragmentManager(), fragments);
      //
      ViewPager pager = (ViewPager) super.findViewById(R.id.viewpager);
      pager.setAdapter(this.mPagerAdapter);
  
  }
  </code></pre>
  
  <p>}</p>
  
  <p>This below is the fragment class that I used to display the layout.</p>
  
  <pre><code>public class Lesson_1 extends Fragment {
  /**
   * (non-Javadoc)
   * 
   * @see android.support.v4.app.Fragment#onCreateView(android.view.LayoutInflater,
   *      android.view.ViewGroup, android.os.Bundle)
   */
  public View onCreateView(LayoutInflater inflater, ViewGroup container,
          Bundle savedInstanceState) {
  
      if (container == null) {
          // We have different layouts, and in one of them this
          // fragment's containing frame doesn't exist. The fragment
          // may still be created from its saved state, but there is
          // no reason to try to create its view hierarchy because it
          // won't be displayed. Note this is not needed -- we could
          // just run the code below, where we would create and return
          // the view hierarchy; it would just never be used.
          return null;
      }
      return (LinearLayout) inflater.inflate(R.layout.lessons1, container,
              false);
  
  }
  </code></pre>
  
  <p>}</p>
  
  <p>And this is my PagerAdapterClass</p>
  
  <pre><code>public class PagerAdapter extends FragmentPagerAdapter {
  
  private List&lt;Fragment&gt; fragments;
  /**
   * @param fm
   * @param fragments
   */
  public PagerAdapter(FragmentManager fm, List&lt;Fragment&gt; fragments) {
      super(fm);
      this.fragments = fragments;
  }
  /* (non-Javadoc)
   * @see android.support.v4.app.FragmentPagerAdapter#getItem(int)
   */
  @Override
  public Fragment getItem(int position) {
      return this.fragments.get(position);
  }
  
  /* (non-Javadoc)
   * @see android.support.v4.view.PagerAdapter#getCount()
   */
  @Override
  public int getCount() {
      return this.fragments.size();
  }
  </code></pre>
  
  <p>}</p>
