本文給大家分享的是在安卓系統(tǒng)中實現(xiàn)讀取搜索聯(lián)系人的代碼，非常的實用，想學(xué)習(xí)安卓開發(fā)的小伙伴一定不要錯過。

代碼很簡單，就不多廢話了

//讀取聯(lián)系人

public static Uri CONTACTSURI = ContactsContract.Contacts.CONTENT_URI;//聯(lián)系人

    public static void getContactsInfo(Context context,String tag){

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

        Cursor cursor = context.getContentResolver().query(CONTACTSURI, projections, null, null, null);

        int albumIndex = cursor.getColumnIndexOrThrow(projections[0]);

        int titleIndex = cursor.getColumnIndexOrThrow(projections[1]);

        Log.d(tag, cursor.getCount()+"");

        while(cursor.moveToNext()){

            String album = cursor.getString(albumIndex);

            String title = cursor.getString(titleIndex);

            Log.d(tag, album+":"+title);

        }

        cursor.close();

    }

    //根據(jù)聯(lián)系人搜索聯(lián)系人信息

    public static void searchContacts(Context context,String tag){

        String searchName = "Wang";

        Uri uri = Uri.withAppendedPath(ContactsContract.Contacts.CONTENT_FILTER_URI, searchName);

    //  Uri uri2 = Uri.withAppendedPath(ContactsContract.PhoneLookup.CONTENT_FILTER_URI, phoneNumber); 根據(jù)電話號碼查找聯(lián)系人

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

        Cursor cursor = context.getContentResolver().query(uri, projection, null, null, null);

        String id = null;

        if (cursor.moveToFirst()) {

            id = cursor.getString(cursor.getColumnIndexOrThrow(ContactsContract.Contacts._ID));

        }

        cursor.close();

        if (id!=null) {

            String where = ContactsContract.Data._ID+"="+id;

            projection = new String[]{ContactsContract.Data.DISPLAY_NAME,ContactsContract.CommonDataKinds.Phone.NUMBER};

            Cursor searchcCursor = context.getContentResolver().query(ContactsContract.Data.CONTENT_URI, projection, where, null, null);

            Log.d(tag, searchcCursor.getCount()+"");

            int nameIndex = searchcCursor.getColumnIndex(projection[0]);

            int numberIndex = searchcCursor.getColumnIndex(projection[1]);

            while(searchcCursor.moveToNext()){

                String name = searchcCursor.getString(nameIndex);

                String number = searchcCursor.getString(numberIndex);

                Log.d(tag, number+":"+name);

            }

            searchcCursor.close();

        }

    }
