I have created a ListView which should Display Contact-(Name,Number,Image).
I retrieved the name and number but, failed to display image.
I used custom adapter here is the adapter code
public class PranzAdapter extends BaseAdapter {
ArrayList<SingleRow> list;
Context c;
PranzAdapter(Context context, ArrayList<SingleRow> listItem){
c = context;
list= listItem;
}
@Override
public int getCount() {
return list.size();
}
@Override
public Object getItem(int position) {
return list.get(position);
}
@Override
public long getItemId(int position) {
return position;
}
@Override
public View getView(int position, View convertView, ViewGroup parent) {
LayoutInflater inflater = (LayoutInflater) c.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
View row = inflater.inflate(R.layout.single_row,null,false);
TextView name = (TextView) row.findViewById(R.id.textView1);
TextView number = (TextView) row.findViewById(R.id.textView2);
ImageView image = (ImageView) row.findViewById(R.id.imageView);
SingleRow singleRow = list.get(position);
name.setText(singleRow.name);
number.setText(singleRow.number);
//Error is this, Previously when any contact doesn't have image it pass `null`
if (singleRow.image!= null) {
image.setImageURI(Uri.parse(singleRow.image));
}
return row;
}
}
Update: I didn't put any default Image for the contact Image, so if any contact doesn't have Image it is throwing NullPointer so you can put a default Image or you have to handle the Exception using if condition.
I can display the name and number but while retrieving the image there is problem.
Here is the code for getting the contact info
public class MainActivity extends Activity {
ListView list;
ArrayList<SingleRow> listItem;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
list = (ListView) findViewById(R.id.listView);
listItem = new ArrayList<SingleRow>();
ContentResolver resolver = getContentResolver();
Cursor cursor = resolver.query(ContactsContract.Contacts.CONTENT_URI, null, null, null, null);
String id;
String name;
String number;
String image;
if (cursor.getCount() > 0) {
while (cursor.moveToNext()) {
id = cursor.getString(cursor.getColumnIndex(ContactsContract.Contacts._ID));
name = cursor.getString(cursor.getColumnIndex(ContactsContract.Contacts.DISPLAY_NAME));
if (Integer.parseInt(cursor.getString(cursor.getColumnIndex(ContactsContract.Contacts.HAS_PHONE_NUMBER))) > 0)
{
Cursor pCur = resolver.query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI, null, ContactsContract.CommonDataKinds.Phone.CONTACT_ID +" = ?", new String[]{id}, null);
while (pCur.moveToNext())
{
number = pCur.getString(pCur.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER));
image = pCur.getString(pCur.getColumnIndex(ContactsContract.CommonDataKinds.Phone.PHOTO_URI));
SingleRow s = new SingleRow(name,number,image);
listItem.add(s);
}
pCur.close();
}
}
}
cursor.close();
list.setAdapter(new PranzAdapter(this, listItem));
}
}
Here is the model class I Used for Individual contact:
public class SingleRow {
String name;
String number;
String image;
//Constructor for Single row
SingleRow (String name,String number,String image){
this.name = name;
this.number = number;
this.image = image;
}
}
