Android ImageView无法访问某些联系人照片

我获取联系人 ID (ContactsContract.Contacts._ID)

我通过检查相应的 ContactsContract.Contacts.PHOTO_ID 是否为 null 来确定照片是否可用代码>.

如果不是，我会为照片构建一个 URI：

Uri personUri = ContentUris.withAppendedId(ContactsContract.Contacts.CONTENT_URI,id);
Uri photoUri=Uri.withAppendedPath(personUri, ContactsContract.Contacts.Photo.CONTENT_DIRECTORY);

然后，我使用其 setImageURI 方法将 photoUri 设置为 ImageView。

对于某些照片，我看到其他联系人的图片，但出现以下异常：

Unable to open content: content://com.android.contacts/contacts/1912/photo
java.io.FileNotFoundException: java.io.FileNotFoundException: No results.
    at android.database.DatabaseUtils.readExceptionWithFileNotFoundExceptionFromParcel(DatabaseUtils.java:123)
    at android.content.ContentProviderProxy.openAssetFile(ContentProviderNative.java:538)
    at android.content.ContentResolver.openAssetFileDescriptor(ContentResolver.java:484)
    at android.content.ContentResolver.openInputStream(ContentResolver.java:319)
    at android.widget.ImageView.resolveUri(ImageView.java:521)
    at android.widget.ImageView.setImageURI(ImageView.java:305)

我不确定为什么它对某些联系人不起作用？

但最重要的是我想知道我应该测试什么以避免这种异常？

原文

I get the contact ID (ContactsContract.Contacts._ID)

I determine if a photo is available by checking if the corrisponding ContactsContract.Contacts.PHOTO_ID is null.

If it's not I build a URI to the photo:

Uri personUri = ContentUris.withAppendedId(ContactsContract.Contacts.CONTENT_URI,id);
Uri photoUri=Uri.withAppendedPath(personUri, ContactsContract.Contacts.Photo.CONTENT_DIRECTORY);

Then I set the photoUri to an ImageView using its setImageURI method.

For some photos I see the picture for other contacts I get the following exception:

Unable to open content: content://com.android.contacts/contacts/1912/photo
java.io.FileNotFoundException: java.io.FileNotFoundException: No results.
    at android.database.DatabaseUtils.readExceptionWithFileNotFoundExceptionFromParcel(DatabaseUtils.java:123)
    at android.content.ContentProviderProxy.openAssetFile(ContentProviderNative.java:538)
    at android.content.ContentResolver.openAssetFileDescriptor(ContentResolver.java:484)
    at android.content.ContentResolver.openInputStream(ContentResolver.java:319)
    at android.widget.ImageView.resolveUri(ImageView.java:521)
    at android.widget.ImageView.setImageURI(ImageView.java:305)

I'm not sure why it is not working for some contacts?

But mostly I'd like do know what should I test for in order to avoid this exception?

您可以使用 ContactsContract.Contacts.openContactPhotoInputStream(Context, Uri) 方法检查与联系人关联的照片是否可读。

例如

InputStream is = ContactsContract.Contacts.openContactPhotoInputStream(getContext().getContentResolver(), personUri);

if (is == null) {
 // Your contact doesn't have a valid photo 
 // i.e. use the default photo for your app
} else {
 // This will always succeed when assigned to an ImageView!
 return Uri photoUri=Uri.withAppendedPath(personUri, ContactsContract.Contacts.Photo.CONTENT_DIRECTORY);  
}

You can use ContactsContract.Contacts.openContactPhotoInputStream(Context, Uri) method to check if the photo associated with a contact is readable or not.

E.g.

InputStream is = ContactsContract.Contacts.openContactPhotoInputStream(getContext().getContentResolver(), personUri);

if (is == null) {
 // Your contact doesn't have a valid photo 
 // i.e. use the default photo for your app
} else {
 // This will always succeed when assigned to an ImageView!
 return Uri photoUri=Uri.withAppendedPath(personUri, ContactsContract.Contacts.Photo.CONTENT_DIRECTORY);  
}
