Question

我有一个独立的应用程序，可以提取联系人的电话号码并将其填入文本框。这作为一个活动很好，但是当我将相同的代码放入一个片段时，我得到一个错误，它无法解析方法'managedQuerry'。我也得到了getContentResover（）的消息。

@Override
public void onActivityResult(int reqCode, int resultCode, Intent data) {
    super.onActivityResult(reqCode, resultCode, data);

    try {
        if (resultCode == Activity.RESULT_OK) {
            Uri contactData = data.getData();
            Cursor cur = managedQuery(contactData, null, null, null, null);
            ContentResolver contect_resolver = getContentResolver();

            if (cur.moveToFirst()) {
                String id = cur.getString(cur.getColumnIndexOrThrow(ContactsContract.Contacts._ID));
                String name = "";
                String no = "";

                Cursor phoneCur = contect_resolver.query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI, null,
                        ContactsContract.CommonDataKinds.Phone.CONTACT_ID + " = ?", new String[] { id }, null);

                if (phoneCur.moveToFirst()) {
                    name = phoneCur.getString(phoneCur.getColumnIndex(ContactsContract.CommonDataKinds.Phone.DISPLAY_NAME));
                    no = phoneCur.getString(phoneCur.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER));
                }

                Log.e("Phone no & name :***: ", name + " : " + no);
                //txt.append(name + " : " + no + "\n");

                editPhoneNum.setText(no);

                id = null;
                name = null;
                no = null;
                phoneCur = null;
            }
            contect_resolver = null;
            cur = null;
            //                      populateContacts();
        }
    } catch (IllegalArgumentException e) {
        e.printStackTrace();
        Log.e("IllegalArgException :: ", e.toString());
    } catch (Exception e) {
        e.printStackTrace();
        Log.e("Error :: ", e.toString());
    }
}

我和你有同样的问题。

这是我的项目对话框，可以获取联系人信息并显示

 private void contactsdialog() {
        final Dialog dialog = new Dialog(getContext());
        dialog.requestWindowFeature(Window.FEATURE_NO_TITLE);
        dialog.setContentView(R.layout.contactsdialog);
        ListView contacts_list = (ListView)dialog.findViewById(R.id.listView);
        Uri uri = ContactsContract.Contacts.CONTENT_URI;

        String[] projection = new String[] {
                ContactsContract.Contacts._ID,
                ContactsContract.Contacts.DISPLAY_NAME,
                ContactsContract.Contacts.PHOTO_ID
        };

        String sortOrder = ContactsContract.Contacts.DISPLAY_NAME + " COLLATE LOCALIZED ASC";
        Cursor cursor =dialog.getContext().getContentResolver().query(uri, projection, null, null, sortOrder);

        ArrayList<String> columnArray1 = new ArrayList<String>();
        ArrayList<String> columnArray2 = new ArrayList<String>();

        while (cursor.moveToNext()) {
            try {
                columnArray2.add(cursor.getString(0));
                columnArray1.add(cursor.getString(1));
            } catch(Exception e) {
                // Log.d("error",e.toString());
            }
        }

        cursor.close();
        String[] colStrArr1 = (String[]) columnArray1.toArray(new String[columnArray1.size()]);
        String[] colStrArr2 = (String[]) columnArray2.toArray(new String[columnArray1.size()]);

        contactadapter adapter = new contactadapter(getActivity(),colStrArr1,colStrArr2);
        contacts_list.setAdapter(adapter);

        dialog.show();
    }

正如您所看到的，我没有使用managedquery，因为它已被弃用。相反，我使用了“getContentResolver（）。query”，它与managedquery相同。你还需要一个像“我的代码中的对话框”这样的对话框名称来绑定getContentResolver（）。查询（因为它不在一个活动上，而我的主类就像你的情况一样是片段）。抱歉英语不好

如果您在managedQuery中使用Fragment，请在getActivity()之前使用managedQuery

Cursor cursor = getActivity().managedQuery(uri, projection, null, null, null);

无法解析方法'managedQuery'
