Android系统联系人

介绍

对Android系统联系人的CRUD操作

使用说明

放在service中操作是最好的，但是试过系统监听联系人变化的onChange方法并不是很好用，有时候会调用多次直接导致ANR

1.这个查询的是在显示界面的字段 剩下的字段是在联系人的详情界面去查询，这样的好处是每次都只需要去查询一个人不用查询全部 查询一个联系人剩下的那些信息还是非常快的

private void updateContactsInfo() { startTime = System.currentTimeMillis(); Uri phoneUri = ContactsContract.CommonDataKinds.Phone.CONTENT_URI; // 联系人Uri； // 查询的字段 String[] phoneProjection = { ContactsContract.CommonDataKinds.Phone.CONTACT_ID,//联系人ID ContactsContract.CommonDataKinds.Phone.RAW_CONTACT_ID, ContactsContract.CommonDataKinds.Phone.DISPLAY_NAME,//姓名 ContactsContract.CommonDataKinds.Phone.DATA,//具体数据项 PHONE_BOOK_LABLE,//首字母 ContactsContract.CommonDataKinds.Phone.PHOTO_ID//图像ID }; // 按照sort_key升序查詢 mQueryHandler.startQuery(0, null, phoneUri, phoneProjection, null, null, ContactsContract.CommonDataKinds.Phone.SORT_KEY_PRIMARY); }

  public class MyAsyncQueryHandler extends AsyncQueryHandler {
    public MyAsyncQueryHandler(ContentResolver resolver) {
        super(resolver);
    }

    @Override
    protected void onQueryComplete(int token, Object cookie, Cursor cursor) {
        super.onQueryComplete(token, cookie, cursor);
        mContactList.clear();
        if (cursor != null && cursor.getCount() > 0) {
            cursor.moveToFirst();
            for (int i = 0; i < cursor.getCount(); i++) {
                cursor.moveToPosition(i);
                int contactId = cursor.getInt(0);
                int rawId = cursor.getInt(1);
                String name = cursor.getString(2);
                String number = cursor.getString(3);
                String sortKey = cursor.getString(4);
                long photoId = cursor.getLong(5);
                // 创建联系人对象
                SortModel contact = new SortModel();
                contact.setSort_id(contactId);
                contact.setRawId(rawId);
                contact.setName(name);
                contact.setNumber(number);
                contact.setSortKey(sortKey);
                contact.setPhotoId(photoId);
                contact.setSortLetters(sortKey);
                mContactList.add(contact);
                if (photoId != 0) {
                    Bitmap bitmap = ContactsTools.getPhoto(contactId, MainActivity.this);
                    contact.setBtHead(bitmap);
                }
            }
        }
        adapter.notifyDataSetChanged();
        adapter.updateListView(mContactList);
        Log.d(TAG, "loadContacts time = " + (System.currentTimeMillis() - startTime));
    }
}

2. 将我们在主界面查询到的RawId传到联系人详情界面，以便查询剩下的所有信息

    mContactId = getIntent().getIntExtra("raw_contact_id", 0);
    if (mContactId > 0) {
        //根据raw_contact_id查询data数据库表，得到联系人邮箱和地址
        ContentResolver contentResolver = this.getContentResolver();
        Cursor cursor = contentResolver.query(ContactsContract.CommonDataKinds.Email.CONTENT_URI,
                new String[]{ContactsContract.CommonDataKinds.Email.DATA},
                ContactsContract.CommonDataKinds.Email.RAW_CONTACT_ID + "=?", new String[]{String.valueOf(mContactId)}, null);
        while (cursor.moveToNext()) {
            String email = cursor.getString(0);
            tvEmail.setText(email);
            MyApplication.sortModel.setEmail(email);
        }
        cursor.close();
        Cursor cursor1 = contentResolver.query(ContactsContract.CommonDataKinds.StructuredPostal.CONTENT_URI, new String[]{ContactsContract.CommonDataKinds.StructuredPostal.STREET,
                        ContactsContract.CommonDataKinds.StructuredPostal.POBOX, ContactsContract.CommonDataKinds.StructuredPostal.NEIGHBORHOOD,
                        ContactsContract.CommonDataKinds.StructuredPostal.CITY, ContactsContract.CommonDataKinds.StructuredPostal.REGION, ContactsContract.CommonDataKinds.StructuredPostal.POSTCODE},
                ContactsContract.CommonDataKinds.StructuredPostal.RAW_CONTACT_ID + "=?", new String[]{String.valueOf(mContactId)}, null);
        while (cursor1.moveToNext()) {
            String street = cursor1.getString(0);
            String pobx = cursor1.getString(1);
            String community = cursor1.getString(2);
            String city = cursor1.getString(3);
            String region = cursor1.getString(4);
            String postCode = cursor1.getString(5);
            StringBuilder sb = new StringBuilder();
            if (street != null) {
                sb.append(street);
            }
            if (pobx != null) {
                sb.append(pobx);
            }
            if (community != null) {
                sb.append(community);
            }
            if (city != null) {
                sb.append(city);
            }
            if (region != null) {
                sb.append(region);
            }
            if (postCode != null) {
                sb.append(postCode);
            }
            tvAddress.setText(sb.toString());
            MyApplication.sortModel.setAddress(sb.toString());
        }
        cursor1.close();
    }
