Android - Retrieve Contact Photo and Display

Question

I am creating a simple application that retrieves the name and phone number of each individual contact and display in a list view along with the contact's photo in a thumbnail sized image-view at the beginning of the row.

I have managed to retrieve and display the name and number but have failed at getting the photo to display after going through many tutorials and stacks.

I eventually rolled it back to just displaying the name and number.

Can anyone help with the contact photo, I have provided my code below.

Thanks in advance!

---Contact getters and setters--- This method gets the name and number correctly but i am not sure if im getting the photo correctly.

 package content;

 import android.net.Uri;


 public class ContactBean {
private String name;
private String phoneNo;
private Uri proPic;

public String getName() {
    return name;
}
public void setName(String name) {
    this.name = name;
}
public String getPhoneNo() {
    return phoneNo;
}
public void setPhoneNo(String phoneNo) {
    this.phoneNo = phoneNo;
}

public Uri getPhotoUri() {
    return this.proPic;
}

public void setPhotoUri(Uri photoUri) {
    this.proPic = proPic;
}

}

    super(act, row, items);

    this.activity = act;
    this.row = row;
    this.items = items;

    for (int i = 0; i < this.getCount(); i++) {
        itemChecked.add(i, false); // initializes all items value with false
    }

}

@Override
public View getView(final int position, View convertView, ViewGroup parent) {
    View view = convertView;
    ViewHolder holder;
    if (view == null) {
        LayoutInflater inflater = (LayoutInflater) activity
                .getSystemService(Context.LAYOUT_INFLATER_SERVICE);
        view = inflater.inflate(row, null);

        holder = new ViewHolder();
        view.setTag(holder);


    } else {
        holder = (ViewHolder) view.getTag();
    }

    if ((items == null) || ((position + 1) > items.size()))
        return view;

    objBean = items.get(position);

    holder.tvname = (TextView) view.findViewById(R.id.tvname);
    holder.tvPhoneNo = (TextView) view.findViewById(R.id.tvphone);
    holder.ivPic = (ImageView) view.findViewById(R.id.profile_pic);

    if (holder.tvname != null && null != objBean.getName()
            && objBean.getName().trim().length() > 0) {
        holder.tvname.setText(Html.fromHtml(objBean.getName()));
    }
    if (holder.tvPhoneNo != null && null != objBean.getPhoneNo()
            && objBean.getPhoneNo().trim().length() > 0) {
        holder.tvPhoneNo.setText(Html.fromHtml(objBean.getPhoneNo()));
    }


    final CheckBox cBox = (CheckBox) view.findViewById(R.id.chkMarkContact); // your
    // CheckBox
    cBox.setOnClickListener(new OnClickListener() {

        public void onClick(View v) {

            CheckBox cb = (CheckBox) v.findViewById(R.id.chkMarkContact);

            if (cb.isChecked()) {
                itemChecked.set(position, true);
                // do some operations here
            } else if (!cb.isChecked()) {
                itemChecked.set(position, false);
                // do some operations here
            }
        }
    });
    cBox.setChecked(itemChecked.get(position)); // this will Check or Uncheck the
    // CheckBox in ListView
    // according to their original
    // position and CheckBox never
    // loss his State when you
    // Scroll the List Items.



    return view;
}

public class ViewHolder {
    public TextView tvname, tvPhoneNo;
    public ImageView ivPic;
}

@Override
public void onClick(View arg0) {
    // TODO Auto-generated method stub

}

}

In the above code i believe i need something similar to this

if (holder.tvPhoneNo != null && null != objBean.getPhoneNo()
            && objBean.getPhoneNo().trim().length() > 0) {
        holder.tvPhoneNo.setText(Html.fromHtml(objBean.getPhoneNo()));
    }

except for the photos to be displayed.

I also have already created an imageview in the xml and declared it in the above code

  holder.ivPic = (ImageView) view.findViewById(R.id.profile_pic);

Answer 1

You try to get the contact id of the contact(phonenumber) and use Bitmapfactory to decode the image as shown in below working code.

InputStream inputStream=null;
String[] projection = new String[]{Contacts._ID};
Uri contactUri = Uri.withAppendedPath(Contacts.CONTENT_FILTER_URI,Uri.encode(phnumber));
Cursor c = getContentResolver().query(contactUri, projection,
    null, null, null);
if (c.moveToFirst()) {
    long contactId=c.getColumnIndex(Contacts._ID);

    inputStream = Contacts.openContactPhotoInputStream(activity.getContentResolver(),
                            ContentUris.withAppendedId(Contacts.CONTENT_URI, cntID));
    c.close();

}

use the inputstream to get bitmap

Bitmap bitmap= BitmapFactory.decodeStream(inputStream);
 holder.ivPic.setImageBitmap(bitmap);
