仅带有图标的布局 [英] Tablayout with icons only

问题描述

我正在使用设计支持来创建选项卡.我还将ViewPager用于可滑动标签.

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

现在，我不知道如何仅使用图标而不是标签中的文本.我试图找出答案，但没有成功.

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.

我的代码:

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);
}
