I'm trying to do an activity with tabs and pagerviewI found this code in a blog but it does not come like making the tabs have icons instead of text ... I put the code:
ViewPagerAdapter.java
class ViewPagerAdapter extends FragmentPagerAdapter {private final List<Fragment> mFragmentList = new ArrayList<>();private final List<String> mFragmentTitleList = new ArrayList<>();public ViewPagerAdapter(FragmentManager manager) {super(manager);}@Overridepublic Fragment getItem(int position) {return mFragmentList.get(position);}@Overridepublic int getCount() {return mFragmentList.size();}public void addFrag(Fragment fragment, String title) {mFragmentList.add(fragment);mFragmentTitleList.add(title);}@Overridepublic CharSequence getPageTitle(int position) {return mFragmentTitleList.get(position);}}Tablayout_in_Android.java
public class Tablayout_in_Android extends Fragment {public Tablayout_in_Android() {// Required empty public constructor}@Overridepublic void onCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState);}@Overridepublic View onCreateView(LayoutInflater inflater, ViewGroup container,Bundle savedInstanceState) {// Inflate the layout for this fragmentreturn inflater.inflate(R.layout.fragment_tablayout_in__android, container, false);}}Method onCreate main class
viewPager = (ViewPager) findViewById(R.id.viewpager);addTabs(viewPager);tabLayout = (TabLayout) findViewById(R.id.pestañas);tabLayout.setupWithViewPager(viewPager);}private void addTabs(ViewPager viewPager) {ViewPagerAdapter adapter = new ViewPagerAdapter(getSupportFragmentManager());adapter.addFrag(new Tablayout_in_Android(), "ONE");adapter.addFrag(new Tablayout_in_Android(), "TWO");adapter.addFrag(new Tablayout_in_Android(), "THREE");viewPager.setAdapter(adapter);}class ViewPagerAdapter extends FragmentPagerAdapter {private final List<Fragment> mFragmentList = new ArrayList<>();private final List<String> mFragmentTitleList = new ArrayList<>();public ViewPagerAdapter(FragmentManager manager) {super(manager);}@Overridepublic Fragment getItem(int position) {return mFragmentList.get(position);}@Overridepublic int getCount() {return mFragmentList.size();}public void addFrag(Fragment fragment, String title) {mFragmentList.add(fragment);mFragmentTitleList.add(title);}@Overridepublic CharSequence getPageTitle(int position) {return mFragmentTitleList.get(position);}}how can i change text for icons? Thanks

Try this:
tabLayout.setupWithViewPager(mViewPager);for (int i = 0; i < mTabLayout.getTabCount(); i++) {tabLayout.getTabAt(i).setIcon(R.drawable.your_icon);}To expand on Jonathan's answer, you can also have a list of icons to show in the tabs. Ensure the icons match the number of tabs you have.
tabLayout.setupWithViewPager(mViewPager);int[] tabIcons = {R.drawable.ic_icon_1,R.drawable.ic_icon_2,R.drawable.ic_icon_3};for(int i=0; i<tabLayout.getTabCount(); i++){if(tabLayout.getTabAt(i) != null){tabLayout.getTabAt(i).setIcon(tabIcons[i]);}}Also, you may want to have the icon and tab label to be in a horizontal orientation, the use app:tabInlineLabel="true" in the TabLayout's xml layout
