Question

我想要做的是在回收者查看器中放置联系人列表。联系人列表应包含联系人图像，联系电话和联系人姓名。我已经解决了三个中的后者，但问题是图像没有分配给联系人姓名。基本上我希望每个联系人都可以从联系人列表或Facebook分配图像。任何人都可以试着看看我哪里出错了。提前谢谢。

public class allContacts extends Fragment {
RecyclerView r;
ContactAdapter adapter;
List <contactInfo> contactLists = new ArrayList<>();

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
    View view = inflater.inflate(R.layout.fragment_all_contacts, container, false);
    r =(RecyclerView)view.findViewById(R.id.contactView);
   loadContact contact = new loadContact();
    contact.execute();
    return view;
}


public class loadContact extends AsyncTask<Void, Void, ArrayList<contactInfo>> {
    ProgressDialog pd;
    ArrayList<contactInfo> contacts;
    contactInfo contact;
    String imnage;
    Cursor phonesCursor;
    Bitmap contactPhoto;

    @Override
    protected void onPreExecute() {
        super.onPreExecute();
        pd = ProgressDialog.show(getActivity(), "Loading Contacts", "Please Wait");
    }


    @Override
    protected ArrayList<contactInfo> doInBackground(Void... params) {
        ContentResolver contentResolver = getActivity().getContentResolver();
        Cursor cursor = contentResolver.query(Contacts.CONTENT_URI, null, null, null, CommonDataKinds.Phone.DISPLAY_NAME + " ASC");


        if (cursor.getCount() > 0) while (cursor.moveToNext()) {

            int hasPhoneNumber = Integer.parseInt(cursor.getString(cursor.getColumnIndex(Contacts.HAS_PHONE_NUMBER)));

            if (hasPhoneNumber > 0) {
                String id = cursor.getString(cursor.getColumnIndex(Contacts._ID));
                String name = cursor.getString(cursor.getColumnIndex(Contacts.DISPLAY_NAME));

                contact = new contactInfo();
                contact.setName(name);

                Cursor phoneCursor = contentResolver.query(
                        CommonDataKinds.Phone.CONTENT_URI, null, CommonDataKinds.Phone.CONTACT_ID + " = ?", new String[]{id}, null);
                if (phoneCursor.moveToNext()) {
                    String phoneNumber = phoneCursor.getString(phoneCursor.getColumnIndex(CommonDataKinds.Phone.NUMBER));
                    contact.setPhoneNumber(phoneNumber);

                    String contactId = cursor.getString(cursor.getColumnIndex(Contacts._ID));


                    Uri uri = ContentUris.withAppendedId(Contacts.CONTENT_URI, Long.parseLong(contactId));
                    InputStream input = Contacts.openContactPhotoInputStream(contentResolver, uri);
                    contactPhoto = BitmapFactory.decodeStream(input);

                }
                phoneCursor.close();


                Cursor emailCursor = contentResolver.query(
                        CommonDataKinds.Email.CONTENT_URI,

                }
                contactLists.add(contact);

        }
        return null;

Answer 1

在你的onBindViewHolder方法中，你试图像这样再次设置相同的图像

loadContact l = new loadContact();
holder.contactPic.setImageBitmap(l.contactPhoto);

而是尝试设置

holder.contactPic.setImageBitmap(contact.getImage());

将联系人图像添加到我的回收者查看器联系号码
