title: How to implement RecyclerView with CardView rows in a Fragment with TabLayout
body: <p>I would like to implement a ListFragment in an Activity that uses a TabLayout, so that I can swipe between the different lists. In the end it should become a booking application so that you can choose between different disciplines and book a certain time slot withing it. However so far I only achieve to do either a ListActivity OR the tabbed activity (the standard one from android studio) but not both. Would be glad if someone could help on this.
  The tabbed activity:</p>
  
  <pre><code>public class Diciplines extends AppCompatActivity {
  
      /**
       * The {@link android.support.v4.view.PagerAdapter} that will provide
       * fragments for each of the sections. We use a
       * {@link FragmentPagerAdapter} derivative, which will keep every
       * loaded fragment in memory. If this becomes too memory intensive, it
       * may be best to switch to a
       * {@link android.support.v4.app.FragmentStatePagerAdapter}.
       */
      private SectionsPagerAdapter mSectionsPagerAdapter;
  
      /**
       * The {@link ViewPager} that will host the section contents.
       */
      private ViewPager mViewPager;
  
      @Override
      protected void onCreate(Bundle savedInstanceState) {
          super.onCreate(savedInstanceState);
          setContentView(R.layout.activity_diciplines);
  
          Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
          setSupportActionBar(toolbar);
          // Create the adapter that will return a fragment for each of the three
          // primary sections of the activity.
          mSectionsPagerAdapter = new SectionsPagerAdapter(getSupportFragmentManager());
  
          // Set up the ViewPager with the sections adapter.
          mViewPager = (ViewPager) findViewById(R.id.container);
          mViewPager.setAdapter(mSectionsPagerAdapter);
  
  
          FloatingActionButton fab = (FloatingActionButton) findViewById(R.id.fab);
          fab.setOnClickListener(new View.OnClickListener() {
              @Override
              public void onClick(View view) {
                  Snackbar.make(view, "Replace with your own action", Snackbar.LENGTH_LONG)
                          .setAction("Action", null).show();
              }
          });
  
      }
  
  
      @Override
      public boolean onCreateOptionsMenu(Menu menu) {
          // Inflate the menu; this adds items to the action bar if it is present.
          getMenuInflater().inflate(R.menu.menu_diciplines, menu);
          return true;
      }
  
      @Override
      public boolean onOptionsItemSelected(MenuItem item) {
          // Handle action bar item clicks here. The action bar will
          // automatically handle clicks on the Home/Up button, so long
          // as you specify a parent activity in AndroidManifest.xml.
          int id = item.getItemId();
  
          //noinspection SimplifiableIfStatement
          if (id == R.id.action_settings) {
              return true;
          }
  
          return super.onOptionsItemSelected(item);
      }
  
  
      /**

       * one of the sections/tabs/pages.

  <p>And I would like to include the listview like this into the upper tabbed activity:</p>
  
  <pre><code>public class DailyCalendar extends ListActivity {
  
  
  public void onCreate(Bundle icicle) {
      super.onCreate(icicle);
      String[] values = new String[] { "9am" ,"10am" ,"11am", "12pm",
      "1pm" , "2pm", "3pm", "4pm" , "5pm", "6pm", "7pm", "8pm", "9pm"};
      ArrayAdapter&lt;String&gt; adapter = new ArrayAdapter&lt;String&gt;(this,
              android.R.layout.simple_list_item_1, values);
      setListAdapter(adapter);
  }
  
  @Override
  protected void onListItemClick(ListView listView, View view, int position, long id) {
      String item = (String) getListAdapter().getItem(position);
      Toast.makeText(this, item + " selected", Toast.LENGTH_LONG).show();
  }
  </code></pre>
  
  <p>Thanks for help!</p>
