android - TabLayout 的setOnTabSelectedListener 和它的setupWithViewPager 有冲突吗？

Question

我用TabLayout和ViewPager，同样，我必须监听TabReselected事件，但似乎它们是冲突的:

mViewPager.setAdapter(...);
mTabLayout.setOnTabSelectedListener(new TabLayout.OnTabSelectedListener() {
            @Override
            public void onTabSelected(TabLayout.Tab tab) {
                Toast.makeText(getActivity(), "selected...", Toast.LENGTH_LONG).show();
            }

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

            }

            @Override
            public void onTabReselected(TabLayout.Tab tab) {
                Toast.makeText(getActivity(), "reselected...", Toast.LENGTH_LONG).show();
            }
});
mTabLayout.setupWithViewPager(mViewPager);

好像我使用setupWithViewPager(mViewPager)时，之前添加的Listener会失效。关键是当选项卡 [[reselected]] 时我需要做其他事情，但是怎么做？

//使用 runnable，因为它需要时间来设置 viewpager :

    viewPager.setAdapter(viewpagerAdapter);
    tabLayout.post(new Runnable() {
        @Override
        public void run() {
            tabLayout.setupWithViewPager(viewPager);

            tabLayout.setOnTabSelectedListener(new TabLayout.OnTabSelectedListener() {
                @Override
                public void onTabSelected(TabLayout.Tab tab) {

                    Toast.makeText(MainActivity.this, "selected...", Toast.LENGTH_LONG).show();
                }

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

                }

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

                    Toast.makeText(MainActivity.this, "reselected...", Toast.LENGTH_LONG).show();
                }
            });
        }
    });
