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);
    }
}
