如何使用Glide Android加载带有"content://"前缀的URI？

Question

我正在尝试使用Glide加载带有URI"content://com.android.contacts/contacts/295"的联系人照片.

我用的时候

Glide.with(context).load(Uri.parse(contactPhoto).into(imageview)

Glide给了我一个FileNotFoundException

java.io.FileNotFoundException: File does not exist; URI: content://com.android.contacts/contacts/264, calling user: android.uid.shared:10006, calling package is one of: [com.android.providers.contacts, com.android.contacts, com.android.providers.userdictionary]

显然Glide试图从错误的地方获取图像.

如果有人指出我如何使用"content://"URI加载照片,我将不胜感激.

ContentResolver为此，您需要使用 a 。

ContentResolver contextResolver = context.getContentResolver();
Uri uri = Uri.parse("content://com.android.contacts/contacts/295");
Bitmap thumbnail = null;
Cursor cursor = contentResolver.query(uri, new String[] {ContactsContract.CommonDataKinds.Photo.PHOTO}, null, null, null);

try {
    if (cursor.moveToFirst()) {
        final byte[] thumbnailBytes = cursor.getBlob(0);
        if (thumbnailBytes != null) {
            thumbnail = BitmapFactory.decodeByteArray(thumbnailBytes, 0, thumbnailBytes.length);
        }
    }
}
finally {
    cursor.close();
}

if (thumbnail != null) {
    imageView.setImageBitmap(thumbnail);
}

尝试这个。这应该有效。
