Tablayout with icons only

I am using design support to create tabs. I am also using ViewPager for swipable tabs.

Now, I don't know how to use only icons instead of texts in tabs. I tried finding out but didn't get any success.

My code:

Toolbar toolbar;
private TabLayout tabLayout;
private ViewPager viewPager;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    viewPager = (ViewPager) findViewById(R.id.pager);
    setupViewPager(viewPager);
    setupTablayout();
}

private void setupTablayout() {
    tabLayout = (TabLayout) findViewById(R.id.tabLayout);
    tabLayout.setTabGravity(TabLayout.GRAVITY_FILL);
    tabLayout.setupWithViewPager(viewPager);
}

class MyPagerAdapter extends FragmentPagerAdapter {

    private final List<Fragment> mFragmentList = new ArrayList<>();
    private final List<String> mFragmentTitleList = new ArrayList<>();

    public MyPagerAdapter(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) {
        mFragmentTitleList.get(position)
    }
}

private void setupViewPager(ViewPager viewPager) {
    MyPagerAdapter adapter = new MyPagerAdapter(getSupportFragmentManager());
    adapter.addFrag(new frag(), "CAT");
    adapter.addFrag(new frag(), "DOG");
    adapter.addFrag(new frag(), "BIRD");
    viewPager.setAdapter(adapter);
}

One approach is setting the icons after TabLayout.setupWithViewPager() method.

mTabLayout.setupWithViewPager(mViewPager);
for (int i = 0; i < mTabLayout.getTabCount(); i++) {
  mTabLayout.getTabAt(i).setIcon(R.drawable.your_icon);
}

The tutorial shown in the following link should cover what you want. https://github.com/codepath/android_guides/wiki/Google-Play-Style-Tabs-using-TabLayout#add-icons-to-tablayout

I copied the relevant section below.

Add Icons to TabLayout

Currently, the TabLayout class does not provide a clean abstraction model that allows for icons in your tab. There are many posted workarounds, one of which is to return a SpannableString, containing your icon in an ImageSpan, from your PagerAdapter's getPageTitle(position) method as shown in the code snippet below:

private int[] imageResId = {
        R.drawable.ic_one,
        R.drawable.ic_two,
        R.drawable.ic_three
};

// ...

@Override
public CharSequence getPageTitle(int position) {
    // Generate title based on item position
    // return tabTitles[position];
    Drawable image = context.getResources().getDrawable(imageResId[position]);
    image.setBounds(0, 0, image.getIntrinsicWidth(), image.getIntrinsicHeight());
    SpannableString sb = new SpannableString(" ");
    ImageSpan imageSpan = new ImageSpan(image, ImageSpan.ALIGN_BOTTOM);
    sb.setSpan(imageSpan, 0, 1, Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);
    return sb;
}

By default, the tab created by TabLayout sets the textAllCaps property to be true, which prevents ImageSpans from being rendered. You can override this behavior by changing the tabTextAppearance property.

  <style name="MyCustomTabLayout" parent="Widget.Design.TabLayout">
        <item name="tabTextAppearance">@style/MyCustomTextAppearance</item>
  </style>

  <style name="MyCustomTextAppearance" parent="TextAppearance.Design.Tab">
        <item name="textAllCaps">false</item>
  </style>

In new version of TabLayout, google added TabItem which easily can add Icon through your XML with following code:

<android.support.design.widget.TabLayout
         app:tabTextColor="@color/gray"
         app:tabMode="fixed"
         app:tabBackground="@color/red"
         app:tabIndicatorHeight="4dp"
         app:tabIndicatorColor="@color/purple"
         app:tabPadding="2dp"
         app:tabSelectedTextColor="@color/white"
         app:tabMinWidth="64dp"
         android:layout_height="wrap_content"
         android:layout_width="match_parent">

     <!--add height and width to TabItem -->
     <android.support.design.widget.TabItem 
             android:text="@string/tab_text"/>

     <android.support.design.widget.TabItem
             android:icon="@drawable/ic_android"/>

 </android.support.design.widget.TabLayout>

try this

    public class GlobalActivity extends AppCompatActivity {
    Toolbar toolbar;
    ViewPager viewPager;
    TabLayout tabLayout;
    ViewPagerAdapter adapter;
    private int[] tabIcons = {
            R.drawable.home_ic,
            R.drawable.biz_ic,
            R.drawable.network_ic,
            R.drawable.offers_ic,
            R.drawable.message_ic_b
    };

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_global_hub);
        tab();
    }
    public void tab(){
        viewPager = (ViewPager) findViewById(R.id.viewpager);
        setupViewPager(viewPager);
        tabLayout = (TabLayout) findViewById(R.id.tablayout);
        tabLayout.setupWithViewPager(viewPager);
        setupTabIcons();

    }
    private void setupTabIcons() {
        tabLayout.getTabAt(0).setIcon(tabIcons[0]);
        tabLayout.getTabAt(1).setIcon(tabIcons[1]);
        tabLayout.getTabAt(2).setIcon(tabIcons[2]);
        tabLayout.getTabAt(3).setIcon(tabIcons[3]);
        tabLayout.getTabAt(4).setIcon(tabIcons[4]);

    }
    public void setupViewPager(ViewPager viewPager){
        adapter = new ViewPagerAdapter(getSupportFragmentManager());
        adapter.addFrag(new GlHubFragment(),"HOME");
        adapter.addFrag(new BizForumFragment(), "BIZ FORUM");
        adapter.addFrag(new NetworkFragment(), "NETWORK");
        adapter.addFrag(new MessagesFragment(), "MESSAGEs");
        adapter.addFrag(new OfferFragmentActivity(), "OFFER");
        viewPager.setAdapter(adapter);
    }

    public class ViewPagerAdapter extends FragmentPagerAdapter{
        private final List<Fragment> mfragmentlist =new ArrayList<>();
        private final List<String> mFragmentTitleList = new ArrayList<>();
        public ViewPagerAdapter(FragmentManager fm) {
            super(fm);
        }

        @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);
        }
    }
