以下是我正在使用的代码

主要活动代码

 public class ManipulationActivity extends Activity {


@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

    setContentView(R.layout.contacts_list_layout);

    Cursor cursor = getCursor();


    ListView contactList = (ListView)findViewById(R.id.contactList);
    contactList.setAdapter(new ContactListCustomCursorAdapter(this, cursor)); //ContactListCustomCursorAdapter is a customized CursorAdapter. I have put the code below this class

}

    //Get Cursor pointing Contacts
private Cursor getCursor() {

    Cursor cursor = getContentResolver().query(ContactsContract.Contacts.CONTENT_URI,null, null, null, null); 
    while (cursor.moveToNext()) { 
       String contactId = cursor.getString(cursor.getColumnIndex( 
       ContactsContract.Contacts._ID)); 
       String hasPhone = cursor.getString(cursor.getColumnIndex(ContactsContract.Contacts.HAS_PHONE_NUMBER)); 
       if (Boolean.parseBoolean(hasPhone)) { 
          // You know it has a number so now query it like this
          Cursor phones = getContentResolver().query( ContactsContract.CommonDataKinds.Phone.CONTENT_URI, null, ContactsContract.CommonDataKinds.Phone.CONTACT_ID +" = "+ contactId, null, null); 
          while (phones.moveToNext()) { 
             String phoneNumber = phones.getString(phones.getColumnIndex( ContactsContract.CommonDataKinds.Phone.NUMBER));                 
          } 
       phones.close(); 
       }
    }
    cursor.close();
    return cursor;
}      

}

ContactListCustomCursorAdapter代码

public class ContactListCustomCursorAdapter extends CursorAdapter {

private Context context;
private Cursor cursor;
private LayoutInflater inflater;
private int username;
private int phoneNumber;

public ContactListCustomCursorAdapter(Context context, Cursor c) {
    super(context, c);
    this.context = context;
    this.cursor = c;
    inflater = LayoutInflater.from(context);

    username = cursor.getColumnIndexOrThrow(ContactsContract.Contacts.DISPLAY_NAME);
}

@Override
public void bindView(View view, Context context, Cursor cursor) {
    TextView userName = (TextView)view.findViewById(R.id.userName);
    userName.setText(cursor.getString(username));

    TextView phoneNumber = (TextView)view.findViewById(R.id.userNumber);
    phoneNumber.setText(cursor.getString(cursor.getColumnIndexOrThrow(ContactsContract.CommonDataKinds.Phone.NUMBER)));
}

@Override
public View newView(Context context, Cursor cursor, ViewGroup parent) {
    final View view = inflater.inflate(R.layout.custom_contact_list_item, parent, false);

    return view;
}

}

我不想使用联系人选择器。

Answer 1

我也得到了这个错误，花了几个小时后我得到了答案。存在CONSTANT COLUMN MISMATCH问题，'data1'或NUMBER是常量属于电话类。

ContactsContract。联系人 .CONTENT_URI不提供编号，因为您必须提及带有查询的投影，它会为您提供结果，借助此功能，您可以获得._id，display_name。但是，如果你想从id获得数字，那么你必须这样，

Cursor cursorPhone = getContentResolver().query(
                ContactsContract.CommonDataKinds.Phone.CONTENT_URI,
                new String[]{ContactsContract.CommonDataKinds.Phone.NUMBER},
                ContactsContract.Contacts._ID +" = " + item_ID,
                null,
                null);

谢谢

Answer 2

首先，关闭传递给CursorAdapter的光标。如果要将光标分配给适配器，则不应将其关闭，只需在onDestroy中为您的活动调用changeCursor（null）。

其次，从代码中我假设您要显示所有联系人及其电话号码的列表，因此您的getCursor方法应该是这样的

private Cursor getCursor() {

    Cursor cursor = getContentResolver().query( ContactsContract.CommonDataKinds.Phone.CONTENT_URI, null, null, null, null); 

    return cursor;
}

你的bindView应该像

@Override
public void bindView(View view, Context context, Cursor cursor) {
    TextView userName = (TextView)view.findViewById(R.id.userName);
    userName.setText(cursor.getString(cursor.getColumnIndexOrThrow(ContactsContract.Contacts.DISPLAY_NAME)));

    TextView phoneNumber = (TextView)view.findViewById(R.id.userNumber);
    phoneNumber.setText(cursor.getString(cursor.getColumnIndexOrThrow(ContactsContract.CommonDataKinds.Phone.NUMBER)));
}

我已经解决了这个问题，确保数据库在需要时打开，在没有时关闭。

获取illegalargumentException：Android中不存在列'data1'
