谁能告诉我哪里出了问题，并指导我去拿照片吗。我搜索了所有地方并实现了代码。但是它们都没有产生所需的结果。以下是您可以从联系人URI获取图像的代码
String image_uri = cursor.getString(cursor.getColumnIndex(ContactsContract.Contacts.PHOTO_THUMBNAIL_URI));
bitmap = MediaStore.Images.Media .getBitmap(this.getContentResolver(), Uri.parse(image_uri));
contactpic.setImageBitmap(bitmap) ;
尝试以下方法获取联系人姓名和联系人照片
private void retrieveContactPhoto() {
Bitmap photo = null;
try {
InputStream inputStream = ContactsContract.Contacts.openContactPhotoInputStream(getContentResolver(),
ContentUris.withAppendedId(ContactsContract.Contacts.CONTENT_URI, new Long(contactID)));
if (inputStream != null) {
photo = BitmapFactory.decodeStream(inputStream);
ImageView imageView = (ImageView) findViewById(R.id.imageView1);
imageView.setImageBitmap(photo);
}
assert inputStream != null;
inputStream.close();
} catch (IOException e) {
e.printStackTrace();
}
}
