Question

我想把未加密的接触图像照片设置为 Android 2. 0 上方的完整屏幕图像背景。我使用以下代码来获得一个剪切的缩略图, 但是由于照片在画廊里是完整的屏幕, 我如何访问这张照片?

这个代码给出了裁剪缩缩图, 我如何获得全屏未加密?

       public static Bitmap loadContactPhoto(ContentResolver cr, long  id) {
        Uri uri =             ContentUris.withAppendedId(ContactsContract.Contacts.CONTENT_URI, id);
        InputStream input = ContactsContract.Contacts.openContactPhotoInputStream(cr, uri);
        if (input == null) {
            return null;
        }
        return BitmapFactory.decodeStream(input);
    }

和机器人文件说

A read-only sub-directory of a single contact that contains the contact s primary photo. The photo may be stored in up to two ways - the default "photo" is a thumbnail-sized image stored directly in the data row, while the "display photo", if present, is a larger version stored as a file.

重复从文件重复到文件

public InputStream openDisplayPhoto(long contactId) {
     Uri contactUri = ContentUris.withAppendedId(Contacts.CONTENT_URI, contactId);
     Uri displayPhotoUri = Uri.withAppendedPath(contactUri, Contacts.Photo.DISPLAY_PHOTO);
     try {
         AssetFileDescriptor fd =
             getContentResolver().openAssetFileDescriptor(displayPhotoUri, "r");
         return fd.createInputStream();
     } catch (IOException e) {
         return null;
     }
 }
