【问题描述】：

我正在尝试从我的设备中检索所有联系电话。我已经为此编写了代码段。但我在检索联系号码列表时遇到错误。我在这里发布我的代码和错误日志。 谢谢。

MainActivity 的 onCreate 中的代码

        contactListText = (TextView) findViewById(R.id.ContactsListText);
        ContactsProvider c = new ContactsProvider(this);
        c.setContactsString();
        String contactList = c.getContactString();
        contactListText.setText(contactList);

ContactsProvider.java

public class ContactsProvider 

    ArrayList<String> contactList;
    Context context;
    String name;

    public ContactsProvider(Context context) 
        this.context = context;
    

    public ArrayList<String> getContactList() 
        return contactList;
    

    public void setContactsString() 

        contactList = new ArrayList<String>();

        Uri uri = ContactsContract.CommonDataKinds.Phone.CONTENT_URI;
        String[] projection    = new String[] ContactsContract.CommonDataKinds.Phone.NUMBER;
         Cursor people = context.getContentResolver().query(uri, projection, null, null, null);

         int indexNumber = people.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER);

         people.moveToFirst();
         do 
             String number = people.getString(indexNumber);
             contactList.add(number);

          while (people.moveToNext());
    

    public String getContactString() 

        if (contactList.size() > 0) 
            StringBuilder contactString = new StringBuilder();

            for (String n : contactList) 

                if (n.length() >= 10  && !n.startsWith("0217")) 
                    n = n.replace(" ", "");
                    n = n.replace("+", "");
                    n = n.replace("-", "");
                    n = n.substring(n.length() - 10);

                    if (contactString.length() != 0) 
                        contactString.append(",");
                    
                    contactString.append(n);
                

            

            return contactString.toString();
         else 
            return null;

在这里查看我的答案***.com/a/26820544/2252830

【参考方案1】：

try 
Log.d(TAG, "Contacts: " + people.getCount());
        people.moveToFirst();
        while (!people.isAfterLast()) 
            String number = people.getString(indexNumber);
         people.add(number);
        
     catch (Exception ignored) 
    

【参考方案2】：

代码在这里：

int indexNumber = people.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER);
people.moveToFirst();
do 
    String number = people.getString(indexNumber);
    contactList.add(number);
 while (people.moveToNext());

不对。你为什么打电话给String number = people.getString(indexNumber);？没有意义。

试试这个：

while (people.moveToNext())
    String number = people.getString(people.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER));
    contactList.add(number);
