我想从联系人中选取照片。我从堆栈溢出中得到了下面的代码，但是我需要为该方法传递什么参数？请帮我从联系人中选取照片
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);
}
我不知道你是否来自同一个链接或没有提及，但你可以参考this。
我还没有试过这个。但是参照这个链接，我想你必须通过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。
我希望这可以帮助您获得联系人图片，电话号码和电子邮件地址。

我需要通过哪个ID。 –
我明白了，谢谢。 –
我也面临着同样的问题，“身份证”是什么ID？与我们分享prabhu M .. – sanjay
