I can not understand how I create TextView and the rest for each tab separately. I'm a newbie, please explain how you do it: D

Here is the code

package com.example.hondle.biling.activity; import android.annotation.SuppressLint; import android.content.Intent; import android.os.Bundle; import android.support.design.widget.TabLayout; import android.support.v4.app.Fragment; import android.support.v4.app.FragmentManager; import android.support.v4.app.FragmentPagerAdapter; import android.support.v4.view.ViewPager; import android.support.v7.app.AppCompatActivity; import android.support.v7.widget.LinearLayoutManager; import android.support.v7.widget.RecyclerView; import android.support.v7.widget.Toolbar; import android.view.LayoutInflater; import android.view.Menu; import android.view.MenuItem; import android.view.View; import android.view.ViewGroup; import android.widget.FrameLayout; import android.widget.Toast; import com.example.hondle.biling.R; import com.example.hondle.biling.SimpleRecyclerAdapter; import com.example.hondle.biling.TabsHeaderActivity; import com.example.hondle.biling.VersionModel; import java.util.ArrayList; import java.util.List; public class TabAnimationActivity extends AppCompatActivity { @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_tab); final Toolbar toolbar = (Toolbar) findViewById(R.id.tabanim_toolbar); setSupportActionBar(toolbar); getSupportActionBar().setDisplayHomeAsUpEnabled(true); final ViewPager viewPager = (ViewPager) findViewById(R.id.tabanim_viewpager); setupViewPager(viewPager); TabLayout tabLayout = (TabLayout) findViewById(R.id.tabanim_tabs); tabLayout.setupWithViewPager(viewPager); tabLayout.setOnTabSelectedListener(new TabLayout.OnTabSelectedListener() { @Override public void onTabSelected(TabLayout.Tab tab) { viewPager.setCurrentItem(tab.getPosition()); switch (tab.getPosition()) { case 0: showToast("One"); break; case 1: showToast("Two"); break; case 2: showToast("Three"); break; } } @Override public void onTabUnselected(TabLayout.Tab tab) { } @Override public void onTabReselected(TabLayout.Tab tab) { } }); } void showToast(String msg) { Toast.makeText(this, msg, Toast.LENGTH_SHORT).show(); } private void setupViewPager(ViewPager viewPager) { ViewPagerAdapter adapter = new ViewPagerAdapter(getSupportFragmentManager()); adapter.addFrag(new DummyFragment(getResources().getColor(R.color.accent_material_light)), "Инфо"); adapter.addFrag(new DummyFragment(getResources().getColor(R.color.ripple_material_light)), "Офисы"); adapter.addFrag(new DummyFragment(getResources().getColor(R.color.button_material_dark)), "Карта"); viewPager.setAdapter(adapter); } @Override public boolean onCreateOptionsMenu(Menu menu) { getMenuInflater().inflate(R.menu.menu_tab_switch, menu); return true; } @Override public boolean onOptionsItemSelected(MenuItem item) { switch (item.getItemId()) { case android.R.id.home: finish(); return true; case R.id.action_switch: Intent intent = new Intent(TabAnimationActivity.this, TabsHeaderActivity.class); startActivity(intent); return true; } return super.onOptionsItemSelected(item); } static class ViewPagerAdapter extends FragmentPagerAdapter { private final List<Fragment> mFragmentList = new ArrayList<>(); private final List<String> mFragmentTitleList = new ArrayList<>(); public ViewPagerAdapter(FragmentManager manager) { super(manager); } @Override public Fragment getItem(int position) { return mFragmentList.get(position); } @Override public int getCount() { return mFragmentList.size(); } public void addFrag(Fragment fragment, String title) { mFragmentList.add(fragment); mFragmentTitleList.add(title); } @Override public CharSequence getPageTitle(int position) { return mFragmentTitleList.get(position); } } public static class DummyFragment extends Fragment { int color; SimpleRecyclerAdapter adapter; public DummyFragment() { } @SuppressLint("ValidFragment") public DummyFragment(int color) { this.color = color; } @Override public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) { View view = inflater.inflate(R.layout.dummy_fragment, container, false); final FrameLayout frameLayout = (FrameLayout) view.findViewById(R.id.dummyfrag_bg); frameLayout.setBackgroundColor(color); RecyclerView recyclerView = (RecyclerView) view.findViewById(R.id.dummyfrag_scrollableview); LinearLayoutManager linearLayoutManager = new LinearLayoutManager(getActivity().getBaseContext()); recyclerView.setLayoutManager(linearLayoutManager); recyclerView.setHasFixedSize(true); List<String> list = new ArrayList<String>(); for (int i = 0; i < VersionModel.data.length; i++) { list.add(VersionModel.data[i]); } adapter = new SimpleRecyclerAdapter(list); recyclerView.setAdapter(adapter); return view; } } }

UPD: Who is not clear what I want. I have 3 tabs and I cannot understand how to interact with the ViewPageAdapter, so that for each tab you can create buttons, text and the rest for each tab. All code led, for more understanding. The design seems to be ordinary, for those who understand, he will understand.

  • Your task and problem in solving it is completely unclear. And why do we need all your code? Show only the problem area. - Yuriy SPb ♦
  • I updated the cap. - Slava Nenashev
  • The problem is still not clear ... Do you know how to display different fragments on different pages? .. - Yuriy SPb ♦

Your problem with this method is:

  private void setupViewPager(ViewPager viewPager) { ViewPagerAdapter adapter = new ViewPagerAdapter(getSupportFragmentManager()); adapter.addFrag(new DummyFragment(getResources().getColor(R.color.accent_material_light)), "Инфо"); adapter.addFrag(new DummyFragment(getResources().getColor(R.color.ripple_material_light)), "Офисы"); adapter.addFrag(new DummyFragment(getResources().getColor(R.color.button_material_dark)), "Карта"); viewPager.setAdapter(adapter); }

If you want to display different elements on each page - you need different fragments.

Alternatively, in the adapter, override the method:

  @Override public Fragment getItem(int i) { DummyFragment fragment = DummyFragment(getResources().getColor(R.color.button_material_dark)), "Карта"); //Тут можно произвести манипуляции с вашим фрагментом return fragment; }
