如何获取联系人照片URI [英] how to get contact photo URI

问题描述

我与Android联系ContentProvider的工作。我有一个的电话号码的，我需要得到的照片的的的 URI 的与该电话号码相关联的接触。我该怎么办呢???

我知道我能得到的的原始数据的照片和建设的的InputStream 的，但我不想输入流，我需要的 URI 。

编辑：最初我用以下code，以获取联系人信息

 开放的URI = Uri.withAppendedPath（PhoneLookup.CONTENT_FILTER_URI，Uri.en code（PHONENO））;
    光标光标= context.getContentResolver（）查询（URI，细节，NULL，NULL，NULL）;
 

解决方案

要使用的电话号码请使用以下code得到conatct ID：

 进口android.provider.ContactsContract.PhoneLookup;

公共字符串fetchContactIdFromPhoneNumber（字符串phoneNumber的）{
    开放的我们的uri = Uri.withAppendedPath（PhoneLookup.CONTENT_FILTER_URI，
        Uri.en code（phoneNumber的））;
    光标光标= this.getContentResolver（）查询（URI，
        新的String [] {PhoneLookup.DISPLAY_NAME，PhoneLookup._ID}，
        NULL，NULL，NULL）;

    字符串的ContactID =;

    如果（cursor.moveToFirst（））{
        做 {
        使用ContactID = cursor.getString（光标
            .getColumnIndex（PhoneLookup._ID））;
        }而（cursor.moveToNext（））;
    }

    返回的ContactID;
  }
 

和使用得到得到contatc照片URI的接触ID。使用下面的code获取照片URI：

 进口android.provider.ContactsContract;
进口android.provider.ContactsContract.CommonDataKinds.Phone;

公众开放的getPhotoUri（长的ContactID）{
    ContentResolver的ContentResolver的= getContentResolver（）;

    尝试 {
        光标光标= ContentResolver的
            .query（ContactsContract.Data.CONTENT_URI，
                空值，
                ContactsContract.Data.CONTACT_ID
                    +=
                    +的ContactID
                    +和

                    + ContactsContract.Data.MIMETYPE
                    +=
                    + ContactsContract.CommonDataKinds.Photo.CONTENT_ITEM_TYPE
                    +'，NULL，NULL）;

        如果（光标！= NULL）{
        如果（！cursor.moveToFirst（））{
            返回null; //没有照片
        }
        } 其他 {
        返回null; //在光标过程中的错误
        }

    }赶上（例外五）{
        e.printStackTrace（）;
        返回null;
    }

    乌里人= ContentUris.withAppendedId（
        ContactsContract.Contacts.CONTENT_URI，使用ContactID）;
    返回Uri.withAppendedPath（人，
        ContactsContract.Contacts.Photo.CONTENT_DIRECTORY）;
  }
 

希望这会有所帮助。

I am working with Android Contact ContentProvider. I have a Phone Number and I need to get the URI of the Photo of the contact associated with this phone number. How can I do it???

I know I can get the raw data of the photo and build an InputStream, but I dont want the input stream, I need the URI.

EDIT: Originally I'm using following code to fetch contact info

    Uri uri = Uri.withAppendedPath(PhoneLookup.CONTENT_FILTER_URI, Uri.encode(phoneNo));
    Cursor cursor = context.getContentResolver().query(uri, details, null, null, null);

解决方案

To get the conatct id using the phone number use the following code:

import android.provider.ContactsContract.PhoneLookup;

public String fetchContactIdFromPhoneNumber(String phoneNumber) {
    Uri uri = Uri.withAppendedPath(PhoneLookup.CONTENT_FILTER_URI,
        Uri.encode(phoneNumber));
    Cursor cursor = this.getContentResolver().query(uri,
        new String[] { PhoneLookup.DISPLAY_NAME, PhoneLookup._ID },
        null, null, null);

    String contactId = "";

    if (cursor.moveToFirst()) {
        do {
        contactId = cursor.getString(cursor
            .getColumnIndex(PhoneLookup._ID));
        } while (cursor.moveToNext());
    }

    return contactId;
  }

and use the contact id obtained to get the contatc photo URI. Use the following code for getting photo URI:

import android.provider.ContactsContract;
import android.provider.ContactsContract.CommonDataKinds.Phone;

public Uri getPhotoUri(long contactId) {
    ContentResolver contentResolver = getContentResolver();

    try {
        Cursor cursor = contentResolver
            .query(ContactsContract.Data.CONTENT_URI,
                null,
                ContactsContract.Data.CONTACT_ID
                    + "="
                    + contactId
                    + " AND "

                    + ContactsContract.Data.MIMETYPE
                    + "='"
                    + ContactsContract.CommonDataKinds.Photo.CONTENT_ITEM_TYPE
                    + "'", null, null);

        if (cursor != null) {
        if (!cursor.moveToFirst()) {
            return null; // no photo
        }
        } else {
        return null; // error in cursor process
        }

    } catch (Exception e) {
        e.printStackTrace();
        return null;
    }

    Uri person = ContentUris.withAppendedId(
        ContactsContract.Contacts.CONTENT_URI, contactId);
    return Uri.withAppendedPath(person,
        ContactsContract.Contacts.Photo.CONTENT_DIRECTORY);
  }

Hope this would help.
