    } 
}

我有一個啓動畫面（活動），運行測試以查看用戶是否有會話。如果不是，則打開LoginActivity。

我認爲這可能是我的RecyclerView的問題。我無法解決它。我希望你能幫助我。謝謝。

編輯

SessionManager：

public void checkLogin(){ 
     // Check login status 
     if(!this.isLoggedIn()){ 
      // user is not logged in redirect him to Login Activity 
      Intent i = new Intent(_context, LoginActivity.class); 
      // Closing all the Activities 
      i.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP); 

      // Add new Flag to start new Activity 
      i.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK); 

      // Starting Login Activity 
      _context.startActivity(i); 
     } else { 
      Intent i = new Intent(_context, MainActivity.class); 
      i.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP); 

      i.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK); 

      _context.startActivity(i); 
     } 

    } 

public boolean isLoggedIn(){ 
     return pref.getBoolean(IS_LOGGED, false); 
    } 
}

要設置到適配器後，初始化的最愛嗎？ – droidev

是的，我是。聲明：'List favoritos;'Initialized：'favoritos = new ArrayList <>（）;'設置爲適配器：'MainAdapter adapter = new MainAdapter（favoritos）;' – Alan

但列表爲空，您正在填充數據AsyncTask對不對？它應該在 – droidev

@Override 
protected void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    setContentView(R.layout.activity_main); 
    new getFavoritos().execute(email); 
} 

private class getFavoritos extends AsyncTask<String, String,List<Podcasts>>{ 

    @Override 
    protected void onPreExecute() { 
     dialog.show(); 
    } 

    @Override 
    protected JSONObject doInBackground(String... args) { 
     //operations 
     return favoritos; 
    } 

    @Override 
    protected void onPostExecute(List<Podcasts> favoritos) { 
     if (dialog != null && dialog.isShowing()) { 
      dialog.dismiss(); 
     } 
     if(List<Podcasts>!=null){ 
     showFavoritosList(List<Podcasts>) 
     } 
    } 
} 

public void showFavoritosList(List<Podcasts>){ 
     final LinearLayoutManager layoutManager = new LinearLayoutManager(this); 
     layoutManager.setOrientation(LinearLayoutManager.VERTICAL); 
     mRecyclerView.setLayoutManager(layoutManager); 

     MainAdapter adapter = new MainAdapter(favoritos); 
     mRecyclerView.setAdapter(adapter); 
}

試試這個，這可能工作。

UPDATE

mRecyclerView = new RecyclerView(this); 
mRecyclerView = (RecyclerView) findViewById(R.id.my_recycler_view);

我看到了這行代碼，你不需要兩次初始化回收視圖。當您使用findViewById時，您將收到RecyclerView的對象，因此new RecyclerView(this);不是必需的，在此情況下無法使用。

更新2

正如我懷疑你又開始在這是一個錯誤的做法您checkLogin方法MainActivity，而不是你可以直接返回boolean值。

例如：

@Override 
protected void onCreate(Bundle savedInstanceState) { 
       boolean isSessionExist = sessionManager.isLoggedIn(); 
       if(isSessionExist){ 
       //open home screen 
       }else{ 
       //open login screen 
       } 
      }

isLoggedIn

public boolean isLoggedIn(){ 
      return pref.getBoolean(IS_LOGGED, false); 
     } 

}

它不再顯示錯誤，但仍在循環中。它保持顯示啓動畫面。 – Alan

你仍然在循環中意味着什麼？ – droidev

我已將日誌添加到我的代碼onStart，onCreate，onResume。所以，如果你看看我發佈的logcat，它永遠不會停止，應用程序仍在運行。 Logcat顯示它正在啓動，創建，不斷恢復。 – Alan
