我想从联系人中挑选照片。我从堆栈溢出得到以下代码，但是我需要为该方法传递哪些参数？请帮帮我
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);
}
【问题讨论】：
不知道你是不是同一个链接，但是你可以参考this。
我没有尝试过。但是参考这个链接，我认为，你必须传递 ContactsContract.Contact 表的 _id。
Cursor cursor=getContentResolver.query(ContactsContract.Contacts.CONTENT_URI,null,null,null,null);
cursor.moveToFirst();
long id=cursor.getString(cursor.getColumnIndex(ContactsContract.Contacts._ID));
loadContactPhoto(getContentResolver(),id) 应该在这里作为参数传递。

我希望这能帮助您获取联系人图片、电话号码和电子邮件地址。
