当我尝试调用此方法“ setupWithViewPager（）”时，我没有找到它

Question

在父类中，因为父类是从LinearLayout扩展而来的，此函数在类Horizo​​ntalScrollView中，我该如何解决此问题

@Override 
protected void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    setContentView(R.layout.activity_main); 

    ViewPager viewPager = findViewById(R.id.viewpager); 
    CategoryAdapter adapter = new CategoryAdapter(getSupportFragmentManager(), this); 
    viewPager.setAdapter(adapter); 
    TableLayout tabLayout = findViewById(R.id.tabs); 
    tabLayout.setupWithViewPager(viewPager); 
} 

Answer 1

此处输入简单错误：

TableLayout tabLayout = findViewById(R.id.tabs); 

应该是：

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