}

解决方案

很简单.

Tab tab = tabLayout.newTab();tab.setCustomLayout( R.layout.whatever );tabLayout.addTab(添加);

您的布局将是一个简单的 TextView，带有一个指定您的图标的 drawableRight.

I am working on Tablayout with text and icon from the following tutorial ..

My question is how to make the icon placed next to the text instead of above them? I am new in Android Development, hopefully you guys can help me out. Thank you in advance, really appreciate the answer..

Here is my java file

public class AllProducts extends AppCompatActivity {

public ViewPager viewPager;
public TabLayout tabLayout;
    public int[] tabIcons = {
    R.drawable.ic_directions_car_white_24dp,
    R.drawable.ic_motorcycle_white_24dp,
    R.drawable.ic_build_white_24dp
};

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.all_products);
    Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
    setSupportActionBar(toolbar);
    getSupportActionBar().setDisplayHomeAsUpEnabled(true);
    getSupportActionBar().setDisplayShowHomeEnabled(true);


    viewPager = (ViewPager) findViewById(R.id.viewpager2);
    setupViewPager(viewPager);

    tabLayout = (TabLayout) findViewById(R.id.sliding_tabs);
    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]);
}


private void setupViewPager(ViewPager viewPager) {
    ViewPagerAdapter adapter = new ViewPagerAdapter(getSupportFragmentManager());
    adapter.addFragment(new Tab1(), "CAR");
    adapter.addFragment(new Tab2(), "MOTORCYCLE");
    adapter.addFragment(new Tab3(), "OTHERS");
    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);
    }

    @Override
    public Fragment getItem(int position) {
        return mFragmentList.get(position);
    }

    @Override
    public int getCount() {
        return mFragmentList.size();
    }

    public void addFragment(Fragment fragment, String title) {
        mFragmentList.add(fragment);
        mFragmentTitleList.add(title);
    }

    @Override
    public CharSequence getPageTitle(int position) {
        return mFragmentTitleList.get(position);
    }
}

@Override
public boolean onOptionsItemSelected(MenuItem item) {
    switch (item.getItemId()) {
        case android.R.id.home:
            finish();
            return true;
        default:
            return super.onOptionsItemSelected(item);
    }
}

}

解决方案

It's easy.

Tab tab = tabLayout.newTab();
tab.setCustomLayout( R.layout.whatever );
tabLayout.addTab(add);

Your layout would be a simple TextView with a drawableRight that specifies your icon.
