试图获取联系信息无效的列数据1

Question

我正在尝试获取有关所选联系人的信息,但不幸的是我得到了异常 Caused by: java.lang.IllegalArgumentException: Invalid column data1 我从Android手册中复制了代码.这是我的代码.我从结果方法的活动中的片段做到这一点.数据不为null,它在查询方法中抛出异常.

case REQUEST_CODE_CONTACT:
                        // Get the URI that points to the selected contact
                        Uri contactUri = data.getData();
                        // We only need the NUMBER column, because there will be only one row in the result
                        String[] projection = {ContactsContract.CommonDataKinds.Phone.NUMBER, ContactsContract.CommonDataKinds.Phone.DISPLAY_NAME};

                        // Perform the query on the contact to get the NUMBER column
                        // We don't need a selection or sort order (there's only one result for the given URI)
                        // CAUTION: The query() method should be called from a separate thread to avoid blocking
                        // your app's UI thread. (For simplicity of the sample, this code doesn't do that.)
                        // Consider using CursorLoader to perform the query.
                        Cursor cursor = getActivity().getApplicationContext().getContentResolver().query(contactUri, projection, null, null, null);
                        cursor.moveToFirst();

                        // Retrieve the phone number from the NUMBER column
                        int columnNumber = cursor.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER);
                        int columnName = cursor.getColumnIndex(ContactsContract.CommonDataKinds.Phone.DISPLAY_NAME);
                        String number = cursor.getString(columnNumber);
                        String name = cursor.getString(columnName);

                        Toast.makeText(getActivity().getApplicationContext(),"You have selected "+name + " " + number,Toast.LENGTH_LONG).show();

你如何开始挑选联系活动？
试试这个.因为我没有设置意图类型而导致类似的问题.

Intent intent = new Intent(Intent.ACTION_PICK, ContactsContract.Contacts.CONTENT_URI);
        intent.setType(ContactsContract.CommonDataKinds.Phone.CONTENT_TYPE);
        startActivityForResult(intent, REQUEST_CODE_CONTACT);

我希望这能帮到您.
