android - 在android中使用内容提供者获取联系电话

Question

我按照本教程学习了内容提供程序的基础知识:http://www.vogella.de/articles/AndroidSQLite/article.html

但想知道如何获取存储在显示名称中的联系电话。尝试使用“ContactsContract.Contacts.CONTENT_VCARD_TYPE”。但是得到一个错误。

如果有解决办法请告诉我。

谢谢

这是一篇关于在an​​droid中使用content provider获取联系电话的好教程

和

可以这样选择联系方式

添加按钮点击事件如

button1.setOnClickListener(new View.OnClickListener() {

            @Override
            public void onClick(View v) {
                // TODO Auto-generated method stub

                i = new Intent(Intent.ACTION_PICK,
                        ContactsContract.Contacts.CONTENT_URI);
                startActivityForResult(i, PICK_CONTACT);
            }
        });


//outside button click

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

        switch (reqCode) {
        case (PICK_CONTACT):


            if (resultCode == Activity.RESULT_OK) {
                getContactInfo(data);
            }
        }
    }

    // onActivityResult

    private void getContactInfo(Intent data) {
        // TODO Auto-generated method stub

         ContentResolver cr = getContentResolver();




        Cursor cursor = managedQuery(data.getData(), null, null, null, null);
        while (cursor.moveToNext()) {
            String contactId = cursor.getString(cursor
                    .getColumnIndex(ContactsContract.Contacts._ID));
            Name = cursor
                    .getString(cursor
                            .getColumnIndexOrThrow(ContactsContract.Contacts.DISPLAY_NAME));

            String hasPhone = cursor
                    .getString(cursor
                            .getColumnIndex(ContactsContract.Contacts.HAS_PHONE_NUMBER));

            Cursor emailCur = cr.query( 
                    ContactsContract.CommonDataKinds.Email.CONTENT_URI, 
                    null,
                    ContactsContract.CommonDataKinds.Email.CONTACT_ID + " = ?", 
                    new String[]{contactId}, null); 


            emailCur.close();






     if (hasPhone.equalsIgnoreCase("1"))
                hasPhone = "true";
            else
                hasPhone = "false";

            if (Boolean.parseBoolean(hasPhone)) {
                Cursor phones = getContentResolver().query(
                        ContactsContract.CommonDataKinds.Phone.CONTENT_URI,
                        null,
                        ContactsContract.CommonDataKinds.Phone.CONTACT_ID
                                + " = " + contactId, null, null);
                while (phones.moveToNext()) {
                    phoneNo = phones
                            .getString(phones
                                    .getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER));
                }
                phones.close();
            }

            pname.setText(Name);
            //
            phno.setText(phoneNo);

        Toast.makeText(this, Name + "   " + phoneNo, Toast.LENGTH_SHORT).show();


        }

    }
