Square up FLOW navigation

Question

我跟着Lukaspili Demo爲電機創建MVP架構項目&流程框架集成。我想在登錄後登錄&之前進行兩項不同的活動。我無法獲取父活動實例來創建新的Intent（ParentActivity.this，NewActivity.class）。有沒有人遇到這種情況？

您應該能夠獲得您的視圖的base context活動。

public static Activity getActivity(Context context) { 
    if(context instanceof Activity) { 
     return (Activity) context; 
    } else if(context instanceof ContextWrapper) { 
     Context baseContext = ((ContextWrapper) context).getBaseContext(); 
     if(baseContext instanceof Activity) { 
      return (Activity) baseContext; 
     } 
    } 
    Log.e(TAG, "No activity could be found in [" + context + "]"); 
    throw new IllegalStateException("No activity could be found in [" + context + "]"); 
}
