Получение фотографий контактов
Я работаю над получением контактов через курсор. Все работает нормально, но отображение фотографий контактов ничего не возвращает. Я не получаю никаких сбоев или ошибок. Мой код
ContactListActivity.java
Cursor cur= getContentResolver().query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI, null,null,null,null);
list.setAdapter(new contactAdapter(getApplicationContext(), cur));
Мой специально созданный адаптер курсора
class contactAdapter extends CursorAdapter{
String Name, phoneNumber;
private Cursor cursor;
private Context ccontext;
private LayoutInflater inflater;
public contactAdapter(Context context, Cursor c) {
super(context, c);
// TODO Auto-generated constructor stub
cursor = c;
ccontext = context;
inflater = LayoutInflater.from(context);
inflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
}

@Override
public void bindView(View view, Context arg1, Cursor arg2) {
// TODO Auto-generated method stub
ViewHolder holder = (ViewHolder) view.getTag();
if (holder == null) {
holder = new ViewHolder();
holder.contactsImage = (ImageView) view.findViewById(R.id.contact_image);
holder.ContactName = (TextView) view.findViewById(R.id.contact_name);
holder.contactCheck = (CheckBox) view.findViewById(R.id.contact_check);
view.setTag(holder);
holder.contactCheck.setOnClickListener(new View.OnClickListener() {

cb.setChecked(cb.isChecked());
// ContactPerson selected = (ContactPerson)cb.getTag();
Log.d("selcted", cb.getTag().toString());
if(cb.isChecked()){
phoneID.add(cb.getTag().toString());
}
}
});
}else{
holder = (ViewHolder) view.getTag();
}
// Uri uri = ContentUris.withAppendedId(ContactsContract.CommonDataKinds.Phone.CONTENT_URI, cursor.getLong(cursor.getColumnIndex(ContactsContract.CommonDataKinds.Phone._ID)));

if(cursor.getString(cursor.getColumnIndex("mimetype")).equals(ContactsContract.CommonDataKinds.Photo.CONTENT_ITEM_TYPE)){
byte[] photoByte = cursor.getBlob(cursor.getColumnIndex("data15"));

Может кто-нибудь, пожалуйста, скажите мне, где я иду не так, и направьте меня, чтобы получить фотографии. Я гуглю везде и внедряю код. Но ни один из них не дал требуемого результата.

Попробуй этот код
private void getContactsDetails() {
Cursor phones = getContentResolver().query(
ContactsContract.CommonDataKinds.Phone.CONTENT_URI, null, null,
null, null);
while (phones.moveToNext()) {
String Name = phones
.getString(phones
.getColumnIndex(ContactsContract.CommonDataKinds.Phone.DISPLAY_NAME));
String Number = phones
.getString(phones
.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER));
String image_uri = phones
.getString(phones
.getColumnIndex(ContactsContract.CommonDataKinds.Phone.PHOTO_URI));
System.out.println("Contact1 : " + Name + ", Number " + Number
+ ", image_uri " + image_uri);
if (image_uri != null) {
image.setImageURI(Uri.parse(image_uri));
}
}
Вот код, который вы можете получить изображение из контактного URI.
String image_uri = cursor.getString(cursor.getColumnIndex(ContactsContract.Contacts.PHOTO_THUMBNAIL_URI));
bitmap = MediaStore.Images.Media .getBitmap(this.getContentResolver(), Uri.parse(image_uri));
contactpic.setImageBitmap(bitmap) ;
Попробуйте описанный ниже метод, чтобы получить имя контакта и фотографию контакта.
private void retrieveContactPhoto() {
Bitmap photo = null;
try {
InputStream inputStream = ContactsContract.Contacts.openContactPhotoInputStream(getContentResolver(),
ContentUris.withAppendedId(ContactsContract.Contacts.CONTENT_URI, new Long(contactID)));
if (inputStream != null) {
photo = BitmapFactory.decodeStream(inputStream);
ImageView imageView = (ImageView) findViewById(R.id.imageView1);
imageView.setImageBitmap(photo);
}
assert inputStream != null;
inputStream.close();
} catch (IOException e) {
e.printStackTrace();
}
}
