Cómo implementar RecyclerView con filas de CardView en un Fragmento con TabLayout

Me gustaría implementar un ListFragment en una actividad que utiliza un TabLayout, de modo que pueda deslizarme entre las diferentes listas. Al final, se convertirá en una aplicación de reserva para que pueda elegir entre diferentes disciplinas y reservar un determinado intervalo de tiempo. Sin embargo, hasta ahora solo logro hacer una actividad de lista O la actividad con tabs (la estándar de android studio) pero no ambas. Me alegraría si alguien pudiera ayudarme con esto. La actividad con tabs:

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); } /** * A {@link FragmentPagerAdapter} that returns a fragment corresponding to * one of the sections/tabs/pages. */ public class SectionsPagerAdapter extends FragmentPagerAdapter { public SectionsPagerAdapter(FragmentManager fm) { super(fm); } @Override public Fragment getItem(int position) { // getItem is called to instantiate the fragment for the given page. // Return a PlaceholderFragment (defined as a static inner class below). return PlaceholderFragment.newInstance(position + 1); } @Override public int getCount() { // Show 3 total pages. return 3; } @Override public CharSequence getPageTitle(int position) { switch (position) { case 0: return "SECTION 1"; case 1: return "SECTION 2"; case 2: return "SECTION 3"; } return null; } } /** * A placeholder fragment containing a simple view. */ public static class PlaceholderFragment extends Fragment { /** * The fragment argument representing the section number for this * fragment. */ private static final String ARG_SECTION_NUMBER = "section_number"; /** * Returns a new instance of this fragment for the given section * number. */ public static PlaceholderFragment newInstance(int sectionNumber) { PlaceholderFragment fragment = new PlaceholderFragment(); Bundle args = new Bundle(); args.putInt(ARG_SECTION_NUMBER, sectionNumber); fragment.setArguments(args); return fragment; } public PlaceholderFragment() { } @Override public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) { View rootView = inflater.inflate(R.layout.fragment_diciplines, container, false); TextView textView = (TextView) rootView.findViewById(R.id.section_label); textView.setText(getString(R.string.section_format, getArguments().getInt(ARG_SECTION_NUMBER))); return rootView; } } } 

Y me gustaría incluir la vista de lista como esta en la actividad de tabs superior:

 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 adapter = new ArrayAdapter(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(); } 

¡Gracias por la ayuda!

Aquí hay un ejemplo simple usando un TabLayout y un RecyclerView con un CardView en cada fila.

Primero, MainActivity, que configura ViewPager y TabLayout:

 public class MainActivity extends AppCompatActivity { @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar); setSupportActionBar(toolbar); // Get the ViewPager and set it's PagerAdapter so that it can display items ViewPager viewPager = (ViewPager) findViewById(R.id.viewpager); PagerAdapter pagerAdapter = new PagerAdapter(getSupportFragmentManager(), MainActivity.this); viewPager.setAdapter(pagerAdapter); // Give the TabLayout the ViewPager TabLayout tabLayout = (TabLayout) findViewById(R.id.tab_layout); tabLayout.setupWithViewPager(viewPager); // Iterate over all tabs and set the custom view for (int i = 0; i < tabLayout.getTabCount(); i++) { TabLayout.Tab tab = tabLayout.getTabAt(i); tab.setCustomView(pagerAdapter.getTabView(i)); } } @Override public void onResume() { super.onResume(); } @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_main, menu); return true; } @Override public boolean onOptionsItemSelected(MenuItem item) { int id = item.getItemId(); if (id == R.id.action_settings) { return true; } return super.onOptionsItemSelected(item); } class PagerAdapter extends FragmentPagerAdapter { String tabTitles[] = new String[] { "Tab One", "Tab Two", "Tab Three" }; Context context; public PagerAdapter(FragmentManager fm, Context context) { super(fm); this.context = context; } @Override public int getCount() { return tabTitles.length; } @Override public Fragment getItem(int position) { switch (position) { case 0: return new BlankFragment(); case 1: return new BlankFragment(); case 2: return new BlankFragment(); } return null; } @Override public CharSequence getPageTitle(int position) { // Generate title based on item position return tabTitles[position]; } public View getTabView(int position) { View tab = LayoutInflater.from(MainActivity.this).inflate(R.layout.custom_tab, null); TextView tv = (TextView) tab.findViewById(R.id.custom_text); tv.setText(tabTitles[position]); return tab; } } } 

activity_main.xml:

      

custom_tab.xml para cada pestaña en TabLayout:

     

Aquí está la clase BlankFragment, que usa un RecyclerView para mostrar una lista:

 import android.support.v4.app.Fragment; import android.support.v7.widget.LinearLayoutManager; import android.support.v7.widget.RecyclerView; import android.view.LayoutInflater; import android.view.View; import android.view.ViewGroup;; public class BlankFragment extends Fragment { public BlankFragment() { // Required empty public constructor } @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); } @Override public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) { // Inflate the layout for this fragment View rootView = inflater.inflate(R.layout.fragment_blank, container, false); RecyclerView rv = (RecyclerView) rootView.findViewById(R.id.rv_recycler_view); rv.setHasFixedSize(true); MyAdapter adapter = new MyAdapter(new String[]{"test one", "test two", "test three", "test four", "test five" , "test six" , "test seven"}); rv.setAdapter(adapter); LinearLayoutManager llm = new LinearLayoutManager(getActivity()); rv.setLayoutManager(llm); return rootView; } } 

fragment_blank.xml:

      

card_item.xml para la lista RecyclerView:

              

Clase MyAdapter para RecyclerView, esto es muy básico y simplemente establece el texto en una de las TextViews:

 import android.support.v7.widget.CardView; import android.support.v7.widget.RecyclerView; import android.view.LayoutInflater; import android.view.View; import android.view.ViewGroup; import android.widget.TextView; public class MyAdapter extends RecyclerView.Adapter { private String[] mDataset; // Provide a reference to the views for each data item // Complex data items may need more than one view per item, and // you provide access to all the views for a data item in a view holder public static class MyViewHolder extends RecyclerView.ViewHolder { public CardView mCardView; public TextView mTextView; public MyViewHolder(View v) { super(v); mCardView = (CardView) v.findViewById(R.id.card_view); mTextView = (TextView) v.findViewById(R.id.tv_text); } } // Provide a suitable constructor (depends on the kind of dataset) public MyAdapter(String[] myDataset) { mDataset = myDataset; } // Create new views (invoked by the layout manager) @Override public MyAdapter.MyViewHolder onCreateViewHolder(ViewGroup parent, int viewType) { // create a new view View v = LayoutInflater.from(parent.getContext()) .inflate(R.layout.card_item, parent, false); // set the view's size, margins, paddings and layout parameters MyViewHolder vh = new MyViewHolder(v); return vh; } @Override public void onBindViewHolder(MyViewHolder holder, final int position) { holder.mTextView.setText(mDataset[position]); holder.mCardView.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View view) { String currentValue = mDataset[position]; Log.d("CardView", "CardView Clicked: " + currentValue); } }); } @Override public int getItemCount() { return mDataset.length; } } 

Dependencias de Gradle utilizadas:

 dependencies { compile fileTree(dir: 'libs', include: ['*.jar']) compile 'com.android.support:appcompat-v7:23.0.1' compile 'com.android.support:design:23.0.1' compile 'com.android.support:cardview-v7:23.0.1' compile 'com.android.support:recyclerview-v7:23.0.1' } 

Aquí está el resultado:
