清单中的Android Studio未声明的活动（尽管我已将其声明）

Question

我目前正在为决赛编写一个应用程序，但似乎无法启动我的一项活动。假设它是一个recyclerView，它将允许用户为自己创建锻炼清单。但是，当我去启动活动时，程序崩溃了。我的错误代码询问我是否已在清单中声明了活动，而我已经这样做了，我想我虽然没有正确执行某些操作，但是我不知道自己做了什么。我进行了搜索，但似乎我的问题很少见，可能是因为它很简单，而且我自己遇到了用户错误。感谢您的任何帮助，谢谢。

我的常规寻呼机活动：

package hbratcher1992.buccaneer.atlantic.edu.fightingforfitness.Main.RoutineList;

import android.content.Context;
import android.content.Intent;
import android.os.Bundle;
import android.support.v4.app.Fragment;
import android.support.v4.app.FragmentManager;
import android.support.v4.app.FragmentStatePagerAdapter;
import android.support.v4.view.ViewPager;
import android.support.v7.app.AppCompatActivity;
import java.util.List;
import java.util.UUID;
import hbratcher1992.buccaneer.atlantic.edu.fightingforfitness.R;

public class RoutinePagerActivity extends AppCompatActivity
{

private static final String EXTRA_ROUTINE_ID = "com.bignerdranch.android.routinelist.routine_id";

private ViewPager mViewPager;
private List<Routine> mRoutines;

public static Intent newIntent(Context packageContext, UUID routineId) {
    Intent intent = new Intent(packageContext, RoutinePagerActivity.class);
    intent.putExtra(EXTRA_ROUTINE_ID, routineId);
    return intent;
}


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

    UUID routineId = (UUID) getIntent().getSerializableExtra(EXTRA_ROUTINE_ID);

    mViewPager = (ViewPager) findViewById(R.id.routine_view_pager);

    mRoutines = RoutineLab.get(this).getRoutines();
    FragmentManager fragmentManager = getSupportFragmentManager();
    mViewPager.setAdapter(new FragmentStatePagerAdapter(fragmentManager) {
        @Override
        public Fragment getItem(int position) {
            Routine crime = mRoutines.get(position);
            return RoutineFragment.newInstance(crime.getId());
        }

        @Override
        public int getCount() {
            return mRoutines.size();
        }
    });

    for (int i = 0; i < mRoutines.size(); i++) {
        if (mRoutines.get(i).getId().equals(routineId)) {
            mViewPager.setCurrentItem(i);
            break;
        }
    }

}

}

我的例行列表活动：

package hbratcher1992.buccaneer.atlantic.edu.fightingforfitness.Main.RoutineList;

import android.support.v4.app.Fragment;

public class RoutineListActivity extends SingleFragmentActivity
{
@Override
protected Fragment createFragment()
{
    return new RoutineListFragment();
}


}
