Question

我正在开发一个处理联系人的Android应用程序。

我在android 1.6中使用了以下代码，它运行正常。

public static Uri getProfilepicture(Activity activity, String address)
{
    Uri personUri = Uri.withAppendedPath(Phones.CONTENT_FILTER_URL, address);
    Cursor phoneCursor = activity.getContentResolver().query(personUri,PHONE_PROJECTION, null, null, null);
    if (phoneCursor.moveToFirst()) 
    {
        int indexPersonId = phoneCursor.getColumnIndex(Phones.PERSON_ID);
        long personId = phoneCursor.getLong(indexPersonId);
        phoneCursor.close();

        Uri uri = ContentUris.withAppendedId(People.CONTENT_URI, personId);
        return uri;
    }
    return null;
}

并在位图中获取照片，如

Bitmap bm =  People.loadContactPhoto(activity,getProfilepicture(activity, ConNum, R.drawable.artist, null);

任何人都可以为Android 2.1建议代码吗？

感谢朋友们试图帮助我。我通过以下代码解决了这个问题。

public static Bitmap getContactPhoto(Activity activity,int contactId) 
{
    Bitmap photo = null;

    final String[] projection = new String[] {
            Contacts.PHOTO_ID                       // the id of the column in the data table for the image
    };

    final Cursor contact = activity.managedQuery(ContactsContract.CommonDataKinds.Phone.CONTENT_URI,projection,Contacts._ID + "=?",new String[]{String.valueOf(contactId)},null);

    if(contact.moveToFirst()) 
    {
        final String photoId = contact.getString(
                contact.getColumnIndex(Contacts.PHOTO_ID));
        if(photoId != null) 
        {
            photo = queryContactBitmap(activity,photoId);
        } 
        else 
        {
            photo = null;
        }
        contact.close();

    }
    contact.close();
    return photo;
}


private static Bitmap queryContactBitmap(Activity activity,String photoId) 
{
    final Cursor photo = activity.managedQuery(Data.CONTENT_URI,new String[] {Photo.PHOTO},Data._ID + "=?",new String[]{photoId},null);

    final Bitmap photoBitmap;
    if(photo.moveToFirst()) 
    {
        byte[] photoBlob = photo.getBlob(
                photo.getColumnIndex(Photo.PHOTO));
        photoBitmap = BitmapFactory.decodeByteArray(
                photoBlob, 0, photoBlob.length);
    } 
    else 
    {
        photoBitmap = null;
    }
    photo.close();
    return photoBitmap;
}

只需传递activity对象和contactId即可。并将其存储到bitmam中。

代码在android 2.1中不起作用
