從一個活動到另一個包含製表符的意圖

我想訪問一個有3個選項卡即3個片段的活動。我通過了一個意圖打開該活動，但只要我點擊它，應用程序就會停止。我究竟做錯了什麼？這是意圖。從一個活動到另一個包含製表符的意圖

public void Registernow() { 

     Intent intent = new Intent(this, Payment.class); 
     startActivity(intent); 

    }

，這裏是我的活動我試圖訪問代碼。

public class Payment extends AppCompatActivity { 

    private Toolbar toolbar; 
    private TabLayout tabLayout; 
    private ViewPager viewPager; 

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

     toolbar = (Toolbar) findViewById(R.id.toolbar); 
     setSupportActionBar(toolbar); 

     getSupportActionBar().setDisplayHomeAsUpEnabled(true); 

     viewPager = (ViewPager) findViewById(R.id.viewpager); 
     setupViewPager(viewPager); 

     tabLayout = (TabLayout) findViewById(R.id.tabs); 
     tabLayout.setupWithViewPager(viewPager);   //assigns viewpager to tablayout 
    } 

    private void setupViewPager(ViewPager viewPager) {  //defines number of tabs by setting appropriate fragment and tab name 
     ViewPagerAdapter adapter = new ViewPagerAdapter(getSupportFragmentManager()); 
     adapter.addFragment(new Recharge(), "RECHARGE"); 
     adapter.addFragment(new Bill(), "BILL"); 
     adapter.addFragment(new Transfer(), "TRANSFER"); 
     viewPager.setAdapter(adapter);      //custom adapter class provides fragments required for the view pager. 
    } 


}

我提到我在調試應用程序時遇到的錯誤。只要我點擊按鈕，就會發生這種情況。

請包括含有錯誤 –

你的錯誤說堆棧跟蹤擴展？您是否已將_Payment_活動註冊到清單文件？ – Piyush

最新錯誤？它的內涵！ – Vijay

您的應用程序的主題應該從Theme.AppCompat.NoActionBar爲了使用Toolbar爲ActionBar
