title: Start an activity from a fragment
body: <p>I have 2 fragments with on both fragments a button. When I press the button I'd like to start a new Activity. But I can't get it to work.</p>
  
  <p>The error I'm getting: <strong>ERROR here: Type mismatch: cannot convert from mFragmentFavorite to Fragment</strong></p>
  
  <p>What am I doing wrong?</p>
  
  <p><strong><em>MyFragmentPagerAdapter</em></strong></p>
  
  <pre><code>import android.support.v4.app.Fragment;
  import android.support.v4.app.FragmentManager;
  import android.support.v4.app.FragmentPagerAdapter;
  
  public class MyFragmentPagerAdapter extends FragmentPagerAdapter{
  
      final int PAGE_COUNT = 3;
  
      /** Constructor of the class */
      public MyFragmentPagerAdapter(FragmentManager fm) {
          super(fm);
      }
  
      /** This method will be invoked when a page is requested to create */
      @Override
      public Fragment getItem(int arg0) {
  
          switch(arg0){
  
          case 0:
              return new FavoriteActivity();
                      //ERROR: Type mismatch: cannot convert from FavoriteActivity to Fragment
  
  
          case 1:
              return new SettingsActivity();
  
  
          default:
              return null;
  
          }       
      }
  
      /** Returns the number of pages */
      @Override
      public int getCount() {
          return PAGE_COUNT;
      }
  }

  <p><strong><em>FavoriteActivity</em></strong></p>
  
  <pre><code>import android.app.Activity;
  import android.content.Intent;
  import android.os.Bundle;
  import android.view.LayoutInflater;
  import android.view.View;
  import android.view.View.OnClickListener;
  import android.view.ViewGroup;
  import android.widget.Button;
  
  public class FavoriteActivity extends Activity{
  
      public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
          View v = inflater.inflate(R.layout.main_favorite, container, false);
  
  
          OnClickListener listnr=new OnClickListener() {
              @Override
              public void onClick(View v) {
                    Intent i= new Intent("aFavorite");
                    startActivity(i);
              }
          };
  
            Button btn =(Button) v.findViewById(R.id.mainFavorite);
            btn.setOnClickListener(listnr);
  
            return v;
      }
  }
  </code></pre>
  
  <p>If FavoriteActivity extends fragments, the error is gone but then I get an error at <code>findViewById(R.id.mainFavorite);</code> and the error is</p>
  
  <blockquote>
    <p>The method findViewById(int) is undefined for the type
    FavoriteActivity</p>
  </blockquote>
  
  <p><strong>EDIT:</strong></p>
  
  <p>When I press the button in the fragment to start the activity then the app crashes
  this is my logcat</p>
