コードに問題があります。連絡先の写真 uri を取得し、ImageView に写真を表示する必要があります。このコードは私が書いたもので、Android 2.3 で正しく動作します。
Uri myUri = getPhotoUriById( this, contactId );
(ImageView)myImageView.setImageUri( myUri );
public static Uri getPhotoUriById( Context context, Long id ) {
if( id == null || context == null ) return null;
Uri photo = Uri.parse( "android.resource://"+ context.getPackageName() +"/" + R.drawable.no_photo );
Cursor cursor = context.getContentResolver().query( Contacts.CONTENT_URI,
new String[]{ Contacts.PHOTO_ID },
Contacts._ID + " = " + id + " AND " + Contacts.PHOTO_ID + " != 0",
null,
null );
if( cursor != null ) {
if( cursor.moveToFirst()) {
photo = ContentUris.withAppendedId( Contacts.CONTENT_URI, id );
photo = Uri.withAppendedPath( photo, Contacts.Photo.CONTENT_DIRECTORY );
}
cursor.close();
}
return photo;
}
しかし、Android 4.0 (ICS) でテストしていたとき。私は多くの問題を抱えてきました。
