不知道为什么会出现此错误并且应用程序崩溃。请帮助大家。其他任何地方都有问题

这是我的班级文件

public class MainActivity extends ActionBarActivity {
    Button login_b1;

    @Override

    protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    requestWindowFeature(Window.FEATURE_NO_TITLE);
    getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,WindowManager.LayoutParams.FLAG_FULLSCREEN);


        setContentView(R.layout.activity_main);


        TextView registerScreen = (TextView) findViewById(R.id.link_to_register);

        // Listening to register new account link
        registerScreen.setOnClickListener(new View.OnClickListener() {

            public void onClick(View v) {
                // Switching to Register screen
                Intent i = new Intent(getApplicationContext(), RegisterActivity.class);
                startActivity(i);
            }
        });

    }
}

将此代码放在注册活动下方。我猜测应该是错误

<intent-filter>
    <action android:name="android.intent.action.DEFAULT" />

    <category android:name="android.intent.category.LAUNCHER" />
</intent-filter>

无法找到显式活动类错误
