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);         }     } ---------------------   作者：徐朵朵的小太阳   来源：   原文：https://blog.csdn.net/GodnessIsMyMine/article/details/83785794   版权声明：本文为博主原创文章，转载请附上博文链接！
