Java 在片段和活动之间交换数据-NullPointerException

java android android-fragments

Java 在片段和活动之间交换数据-NullPointerException,java,android,android-activity,android-fragments,Java,Android,Android Activity,Android Fragments,我的应用程序具有登录功能。登录成功后，您将导航到具有导航抽屉的应用程序的第一页，因此我的大多数屏幕都是片段，而不是活动，并且由BaseActivity.java调用我有一个片段AddShopFragment，用户可以在其中添加有关商店的信息并保存它。在这个片段中，我有一个名为moreinfo的按钮。按下该按钮后，您将导航到名为addmoreforshopActivity的活动。此活动有一个名为lessinfo的按钮，可将您导航到BaseActivity，然后此活动将您和数据发送到AddShop

我的应用程序具有登录功能。登录成功后，您将导航到具有导航抽屉的应用程序的第一页，因此我的大多数屏幕都是片段，而不是活动，并且由

BaseActivity.java

调用

我有一个片段

AddShopFragment

，用户可以在其中添加有关商店的信息并保存它。在这个片段中，我有一个名为

moreinfo

的按钮。按下该按钮后，您将导航到名为

addmoreforshopActivity

的活动。此活动有一个名为

lessinfo

的按钮，可将您导航到

BaseActivity

，然后此活动将您和数据发送到

AddShopFragment

片段

到目前为止，我一直在使用activity和fragment中的数据保存一个商店。因此，我可以在活动之间交换这些信息，以获得更多保存数据的基于数据的活动片段

现在唯一剩下的是，当按下按钮获取更多数据，然后按下按钮获取更少数据时，我不希望删除我的

AddShopFragment

片段中的所有数据

因此，我尝试将数据从

AddShopFragment

fragment发送到

AddMoreInfoForShopActivity

activity，然后发送到

BaseActivity

，然后再次发送到

AddShopFragment

，以便填充文本区域和微调器

请注意，我试图在片段中显示的数据是：类别、子类别、店名、位置、电子邮件和电话。

在尝试显示这些数据之前，所有信息都正确保存在Parse中，因此错误仅与将这些特定数据发送到其他活动并返回片段有关。

这是用户成功登录时发生的异常，因此应用程序必须导航到我已设置的第一个片段：

AddMoreInfoForShopActivity

代码的一部分，用于向

BaseActivity

发送数据：

Intent i = new Intent(AddMoreInfoForShopActivity.this,
                        BaseActivity.class);

                //pass data to an intent to load a specific fragment of reader activity
                i.putExtra("opening", OpeningTime);
                i.putExtra("closing", ClosingTime);
                i.putExtra("dresscoding", dresscoding2);
                i.putExtra("music", music2);
                i.putExtra("otherinfo", otherinfo2);
                i.putExtra("facebook", fb2);
                i.putExtra("moneyperperson", moneyperperson2);
                i.putExtra("smokingarea", smokingarea2);
                i.putExtra("parking", parking2);
                i.putExtra("creditcards", creditcards2);
                i.putExtra("takeout", takeout2);

                i.putExtra("happyhour", happyhour2);
                i.putExtra("outdoorseating", outdoorseating2);
                i.putExtra("reservations", reservations2);
                i.putExtra("appropriategroups", appropriategroup2);
                i.putExtra("appropriatekids", appropratekids2);

                i.putExtra("category", category);
                i.putExtra("subcategory", subcategory);
                i.putExtra("shopname", shopname);
                i.putExtra("location", location);
                i.putExtra("email", email);
                i.putExtra("telephone", telephone);

                overridePendingTransition(R.anim.push_up_in, R.anim.push_up_out);

                startActivity(i);

我的

BaseActivity

部分从活动获取数据，并将其发送回片段：

if (getIntent() != null) { Intent intent = getIntent(); category = intent.getStringExtra("category"); subcategory = intent.getStringExtra("subcategory"); shopname = intent.getStringExtra("shopname"); location = intent.getStringExtra("location"); email = intent.getStringExtra("email"); telephone = intent.getStringExtra("telephone"); } else{ category = ""; subcategory = ""; shopname = ""; location = ""; email = ""; telephone = ""; }

if (getIntent() != null) { Intent i = getIntent(); String opening = i.getStringExtra("opening"); String closing = i.getStringExtra("closing"); String dresscoding = i.getStringExtra("dresscoding"); String music = i.getStringExtra("music"); String otherinfo = i.getStringExtra("otherinfo"); String facebook = i.getStringExtra("facebook"); String moneyperperson = i.getStringExtra("moneyperperson"); String smokingarea = i.getStringExtra("smokingarea"); String creditcards = i.getStringExtra("creditcards"); String parking = i.getStringExtra("parking"); String takeout = i.getStringExtra("takeout"); String delivery = i.getStringExtra("delivery"); String freewifi = i.getStringExtra("freewifi"); String happyhour = i.getStringExtra("happyhour"); String outdoorseating = i.getStringExtra("outdoorseating"); String reservations = i.getStringExtra("reservations"); String appropriategroup = i.getStringExtra("appropriategroups"); String appropratekids = i.getStringExtra("appropriatekids"); String category = i.getStringExtra("category"); String subcategory = i.getStringExtra("subcategory"); String shopname = i.getStringExtra("shopname"); String location = i.getStringExtra("location"); String email = i.getStringExtra("email"); String telephone = i.getStringExtra("telephone"); Fragment fragment = new AddShopFragment(); Bundle bundle=new Bundle(); bundle.putString("opening", opening); bundle.putString("closing", closing); bundle.putString("dresscoding", dresscoding); bundle.putString("music", music); bundle.putString("otherinfo", otherinfo); bundle.putString("facebook", facebook); bundle.putString("moneyperperson", moneyperperson); bundle.putString("smokingarea", smokingarea); bundle.putString("creditcards", creditcards); bundle.putString("parking", parking); bundle.putString("takeout", takeout); bundle.putString("delivery", delivery); bundle.putString("freewifi", freewifi); bundle.putString("happyhour", happyhour); bundle.putString("outdoorseating", outdoorseating); bundle.putString("reservations", reservations); bundle.putString("appropriategroups", appropriategroup); bundle.putString("appropriatekids", appropratekids); bundle.putString("category", category); bundle.putString("subcategory", subcategory); bundle.putString("shopname", shopname); bundle.putString("location", location); bundle.putString("email", email); bundle.putString("telephone", telephone); //set Fragmentclass Arguments fragment.setArguments(bundle); FragmentManager fm = getSupportFragmentManager(); fm.beginTransaction().replace(R.id.content_frame, fragment).commit(); //} }

最后，这是我从
BaseActivity
获取数据并尝试在屏幕上显示数据的方式-
AddShopFragment
：
