滑动正在使用TabLayout点击不起作用？如何在TabLayout上添加点击监听器？

内部活动

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


    tabLayout = (TabLayout) findViewById(R.id.tabs);
    tabLayout.setupWithViewPager(viewPager);

    viewPager.addOnPageChangeListener(new TabLayout.TabLayoutOnPageChangeListener(tabLayout));
    tabLayout.addOnTabSelectedListener(new TabLayout.OnTabSelectedListener() {
        @Override
        public void onTabSelected(TabLayout.Tab tab) {
            viewPager.setCurrentItem(tab.getPosition());
        }

        @Override
        public void onTabUnselected(TabLayout.Tab tab) {

        }

        @Override
        public void onTabReselected(TabLayout.Tab tab) {

        }
    });

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);
    }

}

private void setupViewPager（ViewPager viewPager）{

ViewPagerAdapter adapter = new ViewPagerAdapter（getSupportFragmentManager（））;

    adapter.addFragment(new TabOneFragment(), "TAB1");

    adapter.addFragment(new TabTwoFragement(), "TAB2");

    viewPager.setAdapter(adapter);

}

布局xml文件

    <android.support.design.widget.TabLayout
        android:id="@+id/tabs"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        app:tabMode="fixed"
        app:tabGravity="fill"/>

    <android.support.v4.view.ViewPager
        android:id="@+id/viewpager"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        app:layout_behavior="@string/appbar_scrolling_view_behavior"  />

这对我有用

ViewPager viewPager = (ViewPager) findViewById(R.id.viewpager);
TabLayout tabLayout = (TabLayout) findViewById(R.id.tabs);

ViewPagerAdapter adapter = new ViewPagerAdapter(getSupportFragmentManager());
viewPager.setAdapter(adapter);

SearchFragment searchFragment = new SearchFragment();
MyApplyFragment myApplyFragment = new MyApplyFragment();

adapter.addFragment(searchFragment, "SearchFragment");
adapter.addFragment(myApplyFragment, "MyApplyFragment");

adapter.notifyDataSetChanged();
tabLayout.setupWithViewPager(viewPager);

class ViewPagerAdapter extends FragmentPagerAdapter {
        private final List<Fragment> mFragmentList = new ArrayList<>();
        private final List<String> mFragmentTitleList = new ArrayList<>();

        public ViewPagerAdapter(FragmentManager manager) {
            super(manager);
        }

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

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

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

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

        @Override
        public int getItemPosition(Object object) {
            return super.getItemPosition(object);
        }

    }
