我正在尝试借助 Custom CursorAdapter 将联系人中的姓名和电话号码放入我的自定义 listView，但出现以下错误

例外

这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。

我也遇到了这个错误，花了几个小时后我得到了答案。存在CONSTANT COLUMN MISMATCH 问题，'data1' 或NUMBER 是属于Phone类的常量。

联系人合同。联系人.CONTENT_URI 不提供号码，因为您必须在查询中提及投影，它会给您结果，借助此您可以获得 ._id、display_name。但是，如果你想从 id 获取号码，那么你必须这样做，

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

谢谢

首先，您传递给 CursorAdapter 的光标已关闭。如果您将光标分配给适配器，则不应关闭它，只需在 onDestroy 中为您的活动调用 changeCursor(null) 即可。

其次，从代码中我假设您想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)));
}

我通过确保在需要时打开数据库并在不需要时关闭数据库来解决问题。
