Android 在Tablayout Tablayout.AddOnAbsSelectedListener中（新的Tablayout.OnAbsSelectedListener（）方法无效

我在activity中有三个选项卡，其中有fragment，但方法AddOnAbsSelectedListener不工作，我的片段工作正常，并且我在调试时也有viewPager，它不在方法中

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

    Intent intent = getIntent();
    pos = intent.getIntExtra("position",0);
    tabLayout.addOnTabSelectedListener(new TabLayout.OnTabSelectedListener() {
        @Override
        public void onTabSelected(TabLayout.Tab tab) {
            viewPager.setCurrentItem(tab.getPosition());

            if (tab.getPosition() == 1) {
              tabLayout.getTabAt(pos).select();
                tabLayout.setBackgroundColor(ContextCompat.getColor(Shop.this,
                        R.color.white));
                if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
                    getWindow().setStatusBarColor(ContextCompat.getColor(Shop.this,
                            R.color.white));
                }
            } else if (tab.getPosition() == 2) {
               /* toolbar.setBackgroundColor(ContextCompat.getColor(Shop.this,
                        android.R.color.white));*/
                tabLayout.setBackgroundColor(ContextCompat.getColor(Shop.this,
                        android.R.color.white));
                if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
                    getWindow().setStatusBarColor(ContextCompat.getColor(Shop.this,
                            android.R.color.white));
                }
            } else {
               /* toolbar.setBackgroundColor(ContextCompat.getColor(Shop.this,
                        R.color.white));*/
                tabLayout.setBackgroundColor(ContextCompat.getColor(Shop.this,
                        R.color.white));
                if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
                    getWindow().setStatusBarColor(ContextCompat.getColor(Shop.this,
                            R.color.white));
                }
            }
        }
        @Override
        public void onTabUnselected(TabLayout.Tab tab) {
        }
        @Override
        public void onTabReselected(TabLayout.Tab tab) {
        }
    });

你能这样试试吗

tabLayout.setupWithViewPager(viewPager);
tabLayout.setOnTabSelectedListener(
 new TabLayout.ViewPagerOnTabSelectedListener(viewPager) {
  @Override
  public void onTabSelected(TabLayout.Tab tab) {
      //for selected tab, write your code here...
  }
});

newTabLayout这是什么对不起，请使用您的Tablayout参考'Tablayout'，而不是'newTabLayout'，我将更改answertabLayout.setOnTabSelectedListener（new Tablayout.ViewPagerOnTabSelectedListener）（viewPager）{@Override public void onTabSelected（TabLayout.Tab）{super.onTabSelected（Tab）；}}}）；调试未进入方法抱歉，我已更改了答案，键入错误，您能再试一次吗？抱歉，错误。
