Android 快速获取联系人列表

1.首先要获取相应权限

<uses-permission android:name="android.permission.READ_CONTACTS"/>

<uses-permission android:name="android.permission.WRITE_CONTACTS"/>

<uses-permission android:name="android.permission.GET_ACCOUNTS"/>

注意：6.0以上要动态获取权限

2.获取到相应权限后  开始快速读取本地联系人列表 （handler + Thread 结合使用读取联系人列表 并通过回调回去）

    public void getContactList(final BaseDataSource.GetDataSourceCallback<List<ContactsInfo>> callback) {

        ActivityUtil.runOnUiThread(new Runnable() {

            @Override

            public void run() {

                ContactAsyncQueryHandler asyncQueryHandler = new ContactAsyncQueryHandler(CCApplication.getInstance().getContentResolver(), callback);

                Uri uri = ContactsContract.CommonDataKinds.Phone.CONTENT_URI;

                String[] projection = {

                        ContactsContract.CommonDataKinds.Phone.CONTACT_ID,

                        ContactsContract.CommonDataKinds.Phone._ID,

                        ContactsContract.CommonDataKinds.Phone.DISPLAY_NAME,

                        ContactsContract.CommonDataKinds.Phone.DATA1,

                        ContactsContract.CommonDataKinds.Phone.STARRED,

                        ContactsContract.CommonDataKinds.Phone.PHOTO_THUMBNAIL_URI,

                        "sort_key"};

                asyncQueryHandler.startQuery(0, null, uri, projection, null, null, "sort_key COLLATE LOCALIZED asc");

            }

        });

    }

    private static class ContactAsyncQueryHandler extends AsyncQueryHandler {

        private BaseDataSource.GetDataSourceCallback<List<ContactsInfo>> mCallback;

        public ContactAsyncQueryHandler(ContentResolver cr, BaseDataSource.GetDataSourceCallback<List<ContactsInfo>> callback) {

            super(cr);

            this.mCallback = callback;

        }

        @Override

        protected void onQueryComplete(int token, Object cookie, Cursor cursor) {

            Map<Integer, ContactsInfo> contactIdMap;

            List<ContactsInfo> contactsInfos = new ArrayList<ContactsInfo>();

            if (cursor != null && cursor.getCount() > 0) {

                contactIdMap = new HashMap<>();

                cursor.moveToFirst();

                for (int i = 0; i < cursor.getCount(); i++) {

                    cursor.moveToPosition(i);

                    int contactId = cursor.getInt(0);

                    int id = cursor.getInt(1);

                    String name = cursor.getString(2);

                    String number = cursor.getString(3);

                    int isStarted = cursor.getInt(4);

                    String photo = cursor.getString(5);

                    if (!contactIdMap.containsKey(contactId) && name != null && number != null) {

                        ContactsInfo contactsInfo = new ContactsInfo();

                        contactsInfo.setContactId(contactId);

                        contactsInfo.setName(name);

                        contactsInfo.setPhone(number);

                        contactsInfo.setPhoto(photo);

                        contactsInfo.setStared(isStarted == 1);

                        contactsInfos.add(contactsInfo);

                        contactIdMap.put(contactId, contactsInfo);

                    }

                }

                cursor.close();

            }

            mCallback.onLoaded(contactsInfos);

        }

    }
