Android 簡單聯系人操作

Android中的Contacts聯系人通過ContentProvider對外提供聯系人數據及操作接口。

下面通過簡單例子，來看看有關聯系人的基本操作。

    public class MainActivity extends ListActivity {

        private ArrayList<String> list = new ArrayList<String>();

        private ArrayAdapter adapter;

        /* Called when the activity is first created. /

        @Override

        public void onCreate(Bundle savedInstanceState) {

            super.onCreate(savedInstanceState);

            insert();

            queryByName();

            queryAll();

            adapter = new ArrayAdapter(this,R.layout.main,list);

            this.setListAdapter(adapter);

        }

        //查詢所有聯系人

        public void queryAll() {

            ContentResolver resolver = this.getContentResolver();

            Uri uri = Uri.parse("content://com.android.contacts/contacts");

            Cursor idCursor = resolver.query(uri, new String[] { "_id" }, null, null, null);

            while (idCursor.moveToNext()) {

                //獲取到raw_contacts表中的id

                int id = idCursor.getInt(0);

                //根據獲取到的ID查詢data表中的數據

                uri = Uri.parse("content://com.android.contacts/contacts/" + id + "/data");

                Cursor dataCursor = resolver.query(uri, new String[] { "data1", "mimetype" }, null, null, null);

                StringBuilder sb = new StringBuilder();

                sb.append("id=" + id);

                //查詢聯系人表中的

                while (dataCursor.moveToNext()) {

                    String data = dataCursor.getString(0);

                    String type = dataCursor.getString(1);

                    if ("vnd.android.cursor.item/name".equals(type))

                        sb.append(", name=" + data);

                    else if ("vnd.android.cursor.item/phone_v2".equals(type))

                        sb.append(", phone=" + data);

                    else if ("vnd.android.cursor.item/email_v2".equals(type))

                        sb.append(", email=" + data);

                }

                list.add(sb.toString());

            }

        }

        //根據電話號碼查詢聯系人名稱

        private void queryByName() {

            ContentResolver resolver = this.getContentResolver();

            Uri uri = Uri.parse("content://com.android.contacts/data/phones/filter/1234567");

            Cursor c = resolver.query(uri, new String[] { "display_name" }, null, null, null);

            while (c.moveToNext()) {

                System.out.println(c.getString(0));

            }

        }

        //添加聯系人

        private void insert() {

            ContentValues values = new ContentValues();

            //向raw_contacts插入一條除了ID之外, 其他全部為NULL的記錄, ID是自動生成的

            long id = ContentUris.parseId(resolver.insert(uri, values));
