    ...

    @Override

        ...
        mSectionsPagerAdapter = new SectionsPagerAdapter(getSupportFragmentManager());
        tabLayout = (TabLayout) findViewById(R.id.tabs);

推荐答案

可以使用OnTabChangeListener.见下

You can use OnTabChangeListener.See below

    TabLayout tabLayout = new TabLayout(this);
    tabLayout.addOnTabSelectedListener(new TabLayout.OnTabSelectedListener() {
        @Override
        public void onTabSelected(TabLayout.Tab tab) {
            //do stuff here
        }

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

        }

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

        }
    });

希望能帮到你.
