Активность не запускается, даже если она объявлена ​​в файле манифеста

Question

У меня есть активность, которая не запускается.

Ошибка получает:

android.content.ActivityNotFoundException: Не удается найти явную активность класс {com.example.its_time/com.example.its_time.actiongenre.ActioncomedyActivity}; Вы объявили эту активность в своем AndroidManifest.xml?

Я проверил, и действие объявлено в файле манифеста.

Почему я все еще получаю эту ошибку, хотя ее объявили?

     ListView list = (ListView)findViewById(R.id.listViewGenres); 
     list.setAdapter(adapter); 

    } 


    } 

Это первая часть кода, который берет меня к следующему шагу, этот процесс работает

Это следующий шаги код, который заберет меня к третьему шагу :

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

     populateListView(); 
     registerClickCallback(); 

    } 

    private void registerClickCallback() { 

ListView list = (ListView)findViewById(R.id.listViewActionSubgenres); 

     list.setOnItemClickListener(new AdapterView.OnItemClickListener() { 

      @Override 
      public void onItemClick(AdapterView<?> parent, View view, 
        int position, long id) { 

       Intent intent; 
       switch(position) 
       { 
       case 0: 
        intent = new Intent(ActiongenreActivity.this,Actioncomedyactivity.class); 
        startActivity(intent); 
        break; 
       case 1: 
        intent = new Intent(ActiongenreActivity.this,Actionadventureactivity.class); 
        startActivity(intent); 
        break; 
       case 2: 
        intent = new Intent(ActiongenreActivity.this,ActionWesternActivity.class); 
        startActivity(intent); 
        break; 
       case 3: 
        intent = new Intent(ActiongenreActivity.this,ActiondramaActivity.class); 
        startActivity(intent); 
        break; 
       case 4: 
        intent = new Intent(ActiongenreActivity.this,ActionthrillerActivity.class); 
        startActivity(intent); 
        break; 
       case 5: 
        intent = new Intent(ActiongenreActivity.this,ActionfantaasyActivity.class); 
        startActivity(intent); 
        break; 
       default: 
        break; 
       } 

      } 
     }); 



    } 
    private void populateListView() { 
     String[] myItems = {"Komedi","Äventyr","Western","Drama","Thriller","Fantasi"}; 
     ArrayAdapter<String> adapter = new ArrayAdapter<String>(this,R.layout.the_list,myItems); 
     ListView list = (ListView)findViewById(R.id.listViewActionSubgenres); 
     list.setAdapter(adapter); 
    } 


} 

Но это его третий шаг, который не работает, и как вы можете увидеть код для первого процесса почти идентичен второму

Answer 1

Ваш код имеет Actioncomedyactivity в то время как манифеста ActioncomedyActivity. a против A имеет значение.

Answer 2

Просто замените этот

android:name=".actiongenre.ActioncomedyActivity" 

с вашим полным именем пакета ограждающих ActionComedyActivity как этот

android:name="youCompletePackageName.Actioncomedyactivity"
