【问题描述】：

您好，我正在尝试通过 contentprovider 从联系人表中获取数据，但每次启动我的应用程序时它都会崩溃，

这是我的源代码：

public class WebpreneurActivity extends ListActivity 



        private DBHandler dbHelper;

            private Cursor phones;
            ImageButton imageButton;
             public static long  rowId;
            @Override
            protected void onCreate(Bundle savedInstanceState) 
                Log.d("database1" ,"0");
                Log.d("Your Location4", "ok4:");
                super.onCreate(savedInstanceState);
                Log.d("database1" ,"1");
                setContentView(R.layout.activity_webpreneur);
                Log.d("database1" ,"2");
                //dbHelper = new DBHandler(this);
                Log.d("database1" ,"3");
            //  dbHelper.open();
                  phones = getContentResolver().query(
                            ContactsContract.CommonDataKinds.Phone.CONTENT_URI, null,
                            ContactsContract.Contacts._ID, null,
                            ContactsContract.Contacts.DISPLAY_NAME + " ASC");
                  if (phones.getCount() > 0)  
                        while (phones.moveToFirst()) 

                            if (Integer.parseInt(phones.getString(phones
                                            .getColumnIndex(ContactsContract.Contacts.HAS_PHONE_NUMBER))) > 0) 


                                    String name = phones
                                            .getString(phones
                                                    .getColumnIndex(ContactsContract.CommonDataKinds.Phone.DISPLAY_NAME));

                                    String phoneNumber = phones
                                            .getString(phones
                                                    .getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER));
                                    String contactId = phones
                                            .getString(phones
                                                    .getColumnIndex(ContactsContract.CommonDataKinds.Phone.CONTACT_ID));
                                    System.out.println("contactId="+ contactId+ ", name=" + name + ", phoneNumber=" + phoneNumber);

                            

                        
                        phones.close();

                    

而我的 Logcat 是：

【问题讨论】：

为什么要遍历返回的光标？

我尝试了不同的代码从联系人表中获取数据，这是我从堆栈溢出中复制的代码之一，因为我自己的代码无法获得结果，请您帮我解决这个问题解决，因为我陷入了困境。

再次：为什么要遍历返回的光标？

您的意思是 (phones.getCount() > 0) 先生吗？实际上我刚开始在 android 中编程，我没有足够的想法，请帮助我并告诉我我在哪里制作的错误。

不，我在问为什么你会遍历返回的光标吗？

【参考方案1】：

只是不要将ContactsContract.Contacts._ID 传递给query() 请求：

phones = getContentResolver().query(
                            ContactsContract.CommonDataKinds.Phone.CONTENT_URI, null,
                            null, null,
                            ContactsContract.Contacts.DISPLAY_NAME + " ASC");

更新： 实际上，您的代码中还有一些问题

ContactsContract.CommonDataKinds.Phone 表中没有 ContactsContract.Contacts.HAS_PHONE_NUMBER 列。您应该只取ContactsContract.CommonDataKinds.Phone.NUMBER 并检查它是否为空。

您还应该使用while (phones.moveToNext()) 而不是while (phones.moveToFirst())

请试试这个代码：

phones = getContentResolver().query(
             ContactsContract.CommonDataKinds.Phone.CONTENT_URI, null,
             null, null,
             ContactsContract.Contacts.DISPLAY_NAME + " ASC");
   if (phones.getCount() > 0)  
         while (phones.moveToNext()) 

             String phoneNumber = phones.getString(phones.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER));
             if (!TextUtils.isEmpty(phoneNumber)) 


                     String name = phones.getString(phones.getColumnIndex(ContactsContract.CommonDataKinds.Phone.DISPLAY_NAME));
                     String contactId = phones.getString(phones.getColumnIndex(ContactsContract.CommonDataKinds.Phone.CONTACT_ID));
                     System.out.println("contactId="+ contactId+ ", name=" + name + ", phoneNumber=" + phoneNumber);

好吧，你真的很摇滚，先生，你真的很棒，非常感谢你，非常感谢......
