Android快速获取联系人

获取联系人在Android开发中经常会遇到，最近项目需要用到获取手机联系人的功能，于是写了一个先查询联系人id然后再根据id查询手机号demo，结果慢到怀疑人生（亲测联系人数据1500+）。最后经过优化查询方式后，查询时间在200ms左右（亲测联系人数据1500+）在这里分享给大家，以方便自己好直接拿来用。国际惯例，注：以下测试只查询名字和手机号码

1、查询所有联系人

/**
 * 获取所有联系人
 *
 * @param context 上下文
 * @return 联系人集合
 */
public List<PhoneBookEntity> getContacts(Context context) {
    long currentTimeMillis = System.currentTimeMillis();

    contacts.clear();
    Cursor cursor = null;
    ContentResolver cr = context.getContentResolver();
    try {
        cursor = cr.query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI, PROJECTION, null, null, "sort_key");
        if (cursor != null) {
            final int displayNameIndex = cursor.getColumnIndex(ContactsContract.Contacts.DISPLAY_NAME);
            final int mobileNoIndex = cursor.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER);
            String mobileNo, displayName;
            while (cursor.moveToNext()) {
                mobileNo = cursor.getString(mobileNoIndex);
                displayName = cursor.getString(displayNameIndex);
                contacts.add(new PhoneBookEntity(displayName, mobileNo));
            }
        }
    } catch (Exception e) {
        e.printStackTrace();
    } finally {
        if (cursor != null) {
            Log.d(TAG, "获取所有联系人耗时: " + (System.currentTimeMillis() - currentTimeMillis) + "，共计：" + cursor.getCount());
            cursor.close();
        }
    }
    return contacts;
}

2、通过姓名获取联系人

/**
 * 通过姓名获取联系人
 *
 * @param context     上下文
 * @param contactName 联系人姓名
 * @return 联系人集合
 */
public List<PhoneBookEntity> getContactByName(Context context, String contactName) {
    long currentTimeMillis = System.currentTimeMillis();
    contacts.clear();

    Cursor cursor = null;
    ContentResolver cr = context.getContentResolver();
    String selection = ContactsContract.CommonDataKinds.Phone.DISPLAY_NAME + " like ? ";
    String[] selectionArgs = new String[]{"%" + contactName + "%"};
    try {
        cursor = cr.query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI, PROJECTION, selection, selectionArgs, "sort_key");
        if (cursor != null) {
            final int displayNameIndex = cursor.getColumnIndex(ContactsContract.Contacts.DISPLAY_NAME);
            final int mobileNoIndex = cursor.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER);
            String mobileNo, displayName;
            while (cursor.moveToNext()) {
                mobileNo = cursor.getString(mobileNoIndex);
                displayName = cursor.getString(displayNameIndex);
                contacts.add(new PhoneBookEntity(displayName, mobileNo));
            }
        }
    } catch (Exception e) {
        e.printStackTrace();
    } finally {
        if (cursor != null) {
            cursor.close();
        }
        Log.d(TAG, "通过姓名获取联系人耗时: " + (System.currentTimeMillis() - currentTimeMillis));
    }
    return contacts;
}

3、通过手机号码查询联系人

/**
 * 通过手机号获取联系人
 *
 * @param context 上下文
 * @param number  手机号码
 * @return 联系人集合
 */
public List<PhoneBookEntity> getContactByNumber(Context context, String number) {
    long currentTimeMillis = System.currentTimeMillis();
    contacts.clear();

    Cursor cursor = null;
    ContentResolver cr = context.getContentResolver();
    String selection = ContactsContract.CommonDataKinds.Phone.NUMBER + " like ? ";
    String[] selectionArgs = new String[]{"%" + number + "%"};
    try {
        cursor = cr.query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI, PROJECTION, selection, selectionArgs, "sort_key");
        if (cursor != null) {
            final int displayNameIndex = cursor.getColumnIndex(ContactsContract.Contacts.DISPLAY_NAME);
            final int mobileNoIndex = cursor.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER);
            String mobileNo, displayName;
            while (cursor.moveToNext()) {
                mobileNo = cursor.getString(mobileNoIndex);
                displayName = cursor.getString(displayNameIndex);
                contacts.add(new PhoneBookEntity(displayName, mobileNo));
            }
        }
    } catch (Exception e) {
        e.printStackTrace();
    } finally {
        if (cursor != null) {
            cursor.close();
        }
        Log.d(TAG, "通过手机号获取联系人耗时: " + (System.currentTimeMillis() - currentTimeMillis));
    }
    return contacts;
}
