虽然使用了setOnTabSelectedListener（）但无法选择标签

Question

我是android新手我试图使用制表符布局实现滑动视图。 我已经实现了以下滑动工作正常但无法选择选项卡值

TabLayout tabLayout;
ViewPager viewPager;
@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_contacts);
    tabLayout = (TabLayout)findViewById(R.id.tablayout);
    viewPager = (ViewPager)findViewById(R.id.viewPager);
    viewPager.setAdapter(new CustomAdapter(getSupportFragmentManager(),getApplicationContext()));
    tabLayout.setupWithViewPager(viewPager);
    tabLayout.setOnTabSelectedListener(new TabLayout.OnTabSelectedListener() {
        @Override
        public void onTabSelected(TabLayout.Tab tab) {
            viewPager.setCurrentItem(tab.getPosition());
        }

        @Override
        public void onTabUnselected(TabLayout.Tab tab) {
            viewPager.setCurrentItem(tab.getPosition());
        }

        @Override
        public void onTabReselected(TabLayout.Tab tab) {
            viewPager.setCurrentItem(tab.getPosition());
        }
    });
}

Answer 1

添加监听器，

 tabLayout.setupWithViewPager(viewPager);
 viewPager.addOnPageChangeListener(new TabLayout.TabLayoutOnPageChangeListener(tabLayout));

Answer 2

尝试评论这些内容：

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

    @Override
    public void onTabUnselected(TabLayout.Tab tab) {
        //viewPager.setCurrentItem(tab.getPosition());
    }

    @Override
    public void onTabReselected(TabLayout.Tab tab) {
        //viewPager.setCurrentItem(tab.getPosition());
    }
});
