            }
        }
    }
}

我有一個啟動屏幕（活動），可以運行測試以查看用戶是否有會話。 如果沒有，它將打開LoginActivity。

我認為RecyclerView可能有問題。 我無法解決。 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);
    }
}

  @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，這可能行得通。

UPDATE 

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

我在您的代碼中看到了這一行，您不需要兩次初始化回收站視圖。 當您使用findViewById您將獲得RecyclerView的對象，因此new RecyclerView(this); 不需要，在這種情況下也沒有用。

更新2

我懷疑您會在checkLogin方法中再次啟動MainActivity，這是錯誤的方法，相反，您可以直接返回布爾值。

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);
        }

}
